1 This document details the changes between this version, readline-8.2, and
|
|
jpayne@68
|
2 the previous version, readline-8.1.
|
|
jpayne@68
|
3
|
|
jpayne@68
|
4 1. Changes to Readline
|
|
jpayne@68
|
5
|
|
jpayne@68
|
6 a. Fixed a problem with cleaning up active marks when using callback mode.
|
|
jpayne@68
|
7
|
|
jpayne@68
|
8 b. Fixed a problem with arithmetic comparison operators checking the version.
|
|
jpayne@68
|
9
|
|
jpayne@68
|
10 c. Fixed a problem that could cause readline not to build on systems without
|
|
jpayne@68
|
11 POSIX signal functions.
|
|
jpayne@68
|
12
|
|
jpayne@68
|
13 d. Fixed a bug that could cause readline to crash if the application removed
|
|
jpayne@68
|
14 the callback line handler before readline read all typeahead.
|
|
jpayne@68
|
15
|
|
jpayne@68
|
16 e. Added additional checks for read errors in the middle of readline commands.
|
|
jpayne@68
|
17
|
|
jpayne@68
|
18 f. Fixed a redisplay problem that occurred when switching from the digit-
|
|
jpayne@68
|
19 argument prompt `(arg: N)' back to the regular prompt and the regular
|
|
jpayne@68
|
20 prompt contained invisible characters.
|
|
jpayne@68
|
21
|
|
jpayne@68
|
22 g. Fixed a problem with restoring the prompt when aborting an incremental
|
|
jpayne@68
|
23 search.
|
|
jpayne@68
|
24
|
|
jpayne@68
|
25 h. Fix a problem with characters > 128 not being displayed correctly in certain
|
|
jpayne@68
|
26 single-byte encodings.
|
|
jpayne@68
|
27
|
|
jpayne@68
|
28 i. Fixed a problem with unix-filename-rubout that caused it to delete too much
|
|
jpayne@68
|
29 when applied to a pathname consisting only of one or more slashes.
|
|
jpayne@68
|
30
|
|
jpayne@68
|
31 j. Fixed a display problem that caused the prompt to be wrapped incorrectly if
|
|
jpayne@68
|
32 the screen changed dimensions during a call to readline() and the prompt
|
|
jpayne@68
|
33 became longer than the screen width.
|
|
jpayne@68
|
34
|
|
jpayne@68
|
35 k. Fixed a problem that caused the \r output by turning off bracketed paste
|
|
jpayne@68
|
36 to overwrite the line if terminal echo was disabled.
|
|
jpayne@68
|
37
|
|
jpayne@68
|
38 l. Fixed a bug that could cause colored-completion-prefix to not display if
|
|
jpayne@68
|
39 completion-prefix-display-length was set.
|
|
jpayne@68
|
40
|
|
jpayne@68
|
41 m. Fixed a problem with line wrapping prompts when a group of invisible
|
|
jpayne@68
|
42 characters runs to the right edge of the screen and the prompt extends
|
|
jpayne@68
|
43 longer then the screen width.
|
|
jpayne@68
|
44
|
|
jpayne@68
|
45 n. Fixed a couple problems that could cause rl_end to be set incorrectly by
|
|
jpayne@68
|
46 transpose-words.
|
|
jpayne@68
|
47
|
|
jpayne@68
|
48 o. Prevent some display problems when running a command as the result of a
|
|
jpayne@68
|
49 trap or one bound using `bind -x' and the command generates output.
|
|
jpayne@68
|
50
|
|
jpayne@68
|
51 p. Fixed an issue with multi-line prompt strings that have one or more
|
|
jpayne@68
|
52 invisible characters at the end of a physical line.
|
|
jpayne@68
|
53
|
|
jpayne@68
|
54 q. Fixed an issue that caused a history line's undo list to be cleared when
|
|
jpayne@68
|
55 it should not have been.
|
|
jpayne@68
|
56
|
|
jpayne@68
|
57 r. When replacing a history entry, make sure the existing entry has a non-NULL
|
|
jpayne@68
|
58 timestamp before copying it; it may have been added by the application, not
|
|
jpayne@68
|
59 the history library.
|
|
jpayne@68
|
60
|
|
jpayne@68
|
61 2. New Features in Readline
|
|
jpayne@68
|
62
|
|
jpayne@68
|
63 a. There is now an HS_HISTORY_VERSION containing the version number of the
|
|
jpayne@68
|
64 history library for applications to use.
|
|
jpayne@68
|
65
|
|
jpayne@68
|
66 b. History expansion better understands multiple history expansions that may
|
|
jpayne@68
|
67 contain strings that would ordinarily inhibit history expansion (e.g.,
|
|
jpayne@68
|
68 `abc!$!$').
|
|
jpayne@68
|
69
|
|
jpayne@68
|
70 c. There is a new framework for readline timeouts, including new public
|
|
jpayne@68
|
71 functions to set timeouts and query how much time is remaining before a
|
|
jpayne@68
|
72 timeout hits, and a hook function that can trigger when readline times
|
|
jpayne@68
|
73 out. There is a new state value to indicate a timeout.
|
|
jpayne@68
|
74
|
|
jpayne@68
|
75 d. Automatically bind termcap key sequences for page-up and page-down to
|
|
jpayne@68
|
76 history-search-backward and history-search-forward, respectively.
|
|
jpayne@68
|
77
|
|
jpayne@68
|
78 e. There is a new `fetch-history' bindable command that retrieves the history
|
|
jpayne@68
|
79 entry corresponding to its numeric argument. Negative arguments count back
|
|
jpayne@68
|
80 from the end of the history.
|
|
jpayne@68
|
81
|
|
jpayne@68
|
82 f. `vi-undo' is now a bindable command.
|
|
jpayne@68
|
83
|
|
jpayne@68
|
84 g. There is a new option: `enable-active-region'. This separates control of
|
|
jpayne@68
|
85 the active region and bracketed-paste. It has the same default value as
|
|
jpayne@68
|
86 bracketed-paste, and enabling bracketed paste enables the active region.
|
|
jpayne@68
|
87 Users can now turn off the active region while leaving bracketed paste
|
|
jpayne@68
|
88 enabled.
|
|
jpayne@68
|
89
|
|
jpayne@68
|
90 h. rl_completer_word_break_characters is now `const char *' like
|
|
jpayne@68
|
91 rl_basic_word_break_characters.
|
|
jpayne@68
|
92
|
|
jpayne@68
|
93 i. Readline looks in $LS_COLORS for a custom filename extension
|
|
jpayne@68
|
94 (*.readline-colored-completion-prefix) and uses that as the default color
|
|
jpayne@68
|
95 for the common prefix displayed when `colored-completion-prefix' is set.
|
|
jpayne@68
|
96
|
|
jpayne@68
|
97 j. Two new bindable string variables: active-region-start-color and
|
|
jpayne@68
|
98 active-region-end-color. The first sets the color used to display the
|
|
jpayne@68
|
99 active region; the second turns it off. If set, these are used in place
|
|
jpayne@68
|
100 of terminal standout mode.
|
|
jpayne@68
|
101
|
|
jpayne@68
|
102 k. New readline state (RL_STATE_EOF) and application-visible variable
|
|
jpayne@68
|
103 (rl_eof_found) to allow applications to detect when readline reads EOF
|
|
jpayne@68
|
104 before calling the deprep-terminal hook.
|
|
jpayne@68
|
105
|
|
jpayne@68
|
106 l. There is a new configuration option: --with-shared-termcap-library, which
|
|
jpayne@68
|
107 forces linking the shared readline library with the shared termcap (or
|
|
jpayne@68
|
108 curses/ncurses/termlib) library so applications don't have to do it.
|
|
jpayne@68
|
109
|
|
jpayne@68
|
110 m. Readline now checks for changes to locale settings (LC_ALL/LC_CTYPE/LANG)
|
|
jpayne@68
|
111 each time it is called, and modifies the appropriate locale-specific display
|
|
jpayne@68
|
112 and key binding variables when the locale changes.
|
|
jpayne@68
|
113

114 -------------------------------------------------------------------------------
|
|
jpayne@68
|
115 This document details the changes between this version, readline-8.1, and
|
|
jpayne@68
|
116 the previous version, readline-8.0.
|
|
jpayne@68
|
117
|
|
jpayne@68
|
118 1. Changes to Readline
|
|
jpayne@68
|
119
|
|
jpayne@68
|
120 a. There are a number of fixes that were found as the result of fuzzing with
|
|
jpayne@68
|
121 random input.
|
|
jpayne@68
|
122
|
|
jpayne@68
|
123 b. Changed the revert-all-at-newline behavior to make sure to start at the end
|
|
jpayne@68
|
124 of the history list when doing it, instead of the line where the user hit
|
|
jpayne@68
|
125 return.
|
|
jpayne@68
|
126
|
|
jpayne@68
|
127 c. When parsing `set' commands from the inputrc file or an application, readline
|
|
jpayne@68
|
128 now allows trailing whitespace.
|
|
jpayne@68
|
129
|
|
jpayne@68
|
130 d. Fixed a bug that left a file descriptor open to the history file if the
|
|
jpayne@68
|
131 file size was 0.
|
|
jpayne@68
|
132
|
|
jpayne@68
|
133 e. Fixed a problem with binding key sequences containing meta characters.
|
|
jpayne@68
|
134
|
|
jpayne@68
|
135 f. Fixed a bug that caused the wrong line to be displayed if the user tried to
|
|
jpayne@68
|
136 move back beyond the beginning of the history list, or forward past the end
|
|
jpayne@68
|
137 of the history list.
|
|
jpayne@68
|
138
|
|
jpayne@68
|
139 g. If readline catches SIGTSTP, it now sets a hook that allows the calling
|
|
jpayne@68
|
140 application to handle it if it desires.
|
|
jpayne@68
|
141
|
|
jpayne@68
|
142 h. Fixed a redisplay problem with a prompt string containing embedded newlines.
|
|
jpayne@68
|
143
|
|
jpayne@68
|
144 i. Fixed a problem with completing filenames containing invalid multibyte
|
|
jpayne@68
|
145 sequences when case-insensitive comparisons are enabled.
|
|
jpayne@68
|
146
|
|
jpayne@68
|
147 j. Fixed a redisplay problem with prompt strings containing invisible multibyte
|
|
jpayne@68
|
148 characters.
|
|
jpayne@68
|
149
|
|
jpayne@68
|
150 k. Fixed a problem with multibyte characters mapped to editing commands that
|
|
jpayne@68
|
151 modify the search string in incremental search.
|
|
jpayne@68
|
152
|
|
jpayne@68
|
153 l. Fixed a bug with maintaining the key sequence while resolving a bound
|
|
jpayne@68
|
154 command in the presence of ambiguous sequences (sequences with a common
|
|
jpayne@68
|
155 prefix), in most cases while attempting to unbind it.
|
|
jpayne@68
|
156
|
|
jpayne@68
|
157 m. Fixed several buffer overflows found as the result of fuzzing.
|
|
jpayne@68
|
158
|
|
jpayne@68
|
159 n. Reworked backslash handling when translating key sequences for key binding
|
|
jpayne@68
|
160 to be more uniform and consistent, which introduces a slight backwards
|
|
jpayne@68
|
161 incompatibility.
|
|
jpayne@68
|
162
|
|
jpayne@68
|
163 o. Fixed a bug with saving the history that resulted in errors not being
|
|
jpayne@68
|
164 propagated to the calling application when the history file is not writable.
|
|
jpayne@68
|
165
|
|
jpayne@68
|
166 p. Readline only calls chown(2) on a newly-written history file if it really
|
|
jpayne@68
|
167 needs to, instead of having it be a no-op.
|
|
jpayne@68
|
168
|
|
jpayne@68
|
169 q. Readline now behaves better when operate-and-get-next is used when the
|
|
jpayne@68
|
170 history list is `full': when there are already $HISTSIZE entries.
|
|
jpayne@68
|
171
|
|
jpayne@68
|
172 r. Fixed a bug that could cause vi redo (`.') of a replace command not to work
|
|
jpayne@68
|
173 correctly in the C or POSIX locale.
|
|
jpayne@68
|
174
|
|
jpayne@68
|
175 s. Fixed a bug with vi-mode digit arguments that caused the last command to be
|
|
jpayne@68
|
176 set incorrectly. This prevents yank-last-arg from working as intended, for
|
|
jpayne@68
|
177 example.
|
|
jpayne@68
|
178
|
|
jpayne@68
|
179 t. Make sure that all undo groups are closed when leaving vi insertion mode.
|
|
jpayne@68
|
180
|
|
jpayne@68
|
181 u. Make sure that the vi-mode `C' and `c' commands enter insert mode even if
|
|
jpayne@68
|
182 the motion command doesn't have any effect.
|
|
jpayne@68
|
183
|
|
jpayne@68
|
184 v. Fixed several potential memory leaks in the callback mode context handling.
|
|
jpayne@68
|
185
|
|
jpayne@68
|
186 w. If readline is handling a SIGTTOU, make sure SIGTTOU is blocked while
|
|
jpayne@68
|
187 executing the terminal cleanup code, since it's no longer run in a signal
|
|
jpayne@68
|
188 handling context.
|
|
jpayne@68
|
189
|
|
jpayne@68
|
190 x. Fixed a bug that could cause an application with an application-specific
|
|
jpayne@68
|
191 redisplay function to crash if the line data structures had not been
|
|
jpayne@68
|
192 initialized.
|
|
jpayne@68
|
193
|
|
jpayne@68
|
194 y. Terminals that are named "dumb" or unknown do not enable bracketed paste
|
|
jpayne@68
|
195 by default.
|
|
jpayne@68
|
196
|
|
jpayne@68
|
197 z. Ensure that disabling bracketed paste turns off highlighting the incremental
|
|
jpayne@68
|
198 search string when the search is successful.
|
|
jpayne@68
|
199
|
|
jpayne@68
|
200 2. New Features in Readline
|
|
jpayne@68
|
201
|
|
jpayne@68
|
202 a. If a second consecutive completion attempt produces matches where the first
|
|
jpayne@68
|
203 did not, treat it as a new completion attempt and insert a match as
|
|
jpayne@68
|
204 appropriate.
|
|
jpayne@68
|
205
|
|
jpayne@68
|
206 b. Bracketed paste mode works in more places: incremental search strings, vi
|
|
jpayne@68
|
207 overstrike mode, character search, and reading numeric arguments.
|
|
jpayne@68
|
208
|
|
jpayne@68
|
209 c. Readline automatically switches to horizontal scrolling if the terminal has
|
|
jpayne@68
|
210 only one line.
|
|
jpayne@68
|
211
|
|
jpayne@68
|
212 d. Unbinding all key sequences bound to a particular readline function now
|
|
jpayne@68
|
213 descends into keymaps for multi-key sequences.
|
|
jpayne@68
|
214
|
|
jpayne@68
|
215 e. rl-clear-display: new bindable command that clears the screen and, if
|
|
jpayne@68
|
216 possible, the scrollback buffer (bound to emacs mode M-C-l by default).
|
|
jpayne@68
|
217
|
|
jpayne@68
|
218 f. New active mark and face feature: when enabled, it will highlight the text
|
|
jpayne@68
|
219 inserted by a bracketed paste (the `active region') and the text found by
|
|
jpayne@68
|
220 incremental and non-incremental history searches. This is tied to bracketed
|
|
jpayne@68
|
221 paste and can be disabled by turning off bracketed paste.
|
|
jpayne@68
|
222
|
|
jpayne@68
|
223 g. Readline sets the mark in several additional commands.
|
|
jpayne@68
|
224
|
|
jpayne@68
|
225 h. Bracketed paste mode is enabled by default. There is a configure-time
|
|
jpayne@68
|
226 option (--enable-bracketed-paste-default) to set the default to on or off.
|
|
jpayne@68
|
227
|
|
jpayne@68
|
228 i. Readline tries to take advantage of the more regular structure of UTF-8
|
|
jpayne@68
|
229 characters to identify the beginning and end of characters when moving
|
|
jpayne@68
|
230 through the line buffer.
|
|
jpayne@68
|
231
|
|
jpayne@68
|
232 j. The bindable operate-and-get-next command (and its default bindings) are
|
|
jpayne@68
|
233 now part of readline instead of a bash-specific addition.
|
|
jpayne@68
|
234
|
|
jpayne@68
|
235 k. The signal cleanup code now blocks SIGINT while processing after a SIGINT.
|
|
jpayne@68
|
236

238 This document details the changes between this version, readline-8.0, and the
|
|
jpayne@68
|
239 previous version, readline-7.0.
|
|
jpayne@68
|
240
|
|
jpayne@68
|
241 1. Changes to Readline
|
|
jpayne@68
|
242
|
|
jpayne@68
|
243 a. Added a guard to prevent nested macros from causing an infinite expansion
|
|
jpayne@68
|
244 loop.
|
|
jpayne@68
|
245
|
|
jpayne@68
|
246 b. Instead of allocating enough history list entries to hold the maximum list
|
|
jpayne@68
|
247 size, cap the number allocated initially.
|
|
jpayne@68
|
248
|
|
jpayne@68
|
249 c. Added a strategy to avoid allocating huge amounts of memory if a block of
|
|
jpayne@68
|
250 history entries without timestamps occurs after a block with timestamps.
|
|
jpayne@68
|
251
|
|
jpayne@68
|
252 d. Added support for keyboard timeouts when an ESC character is the last
|
|
jpayne@68
|
253 character in a macro.
|
|
jpayne@68
|
254
|
|
jpayne@68
|
255 e. There are several performance improvements when in a UTF-8 locale.
|
|
jpayne@68
|
256
|
|
jpayne@68
|
257 f. Readline does a better job of preserving the original set of blocked
|
|
jpayne@68
|
258 signals when using pselect() to wait for input.
|
|
jpayne@68
|
259
|
|
jpayne@68
|
260 g. Fixed a bug that caused multibyte characters in macros to be mishandled.
|
|
jpayne@68
|
261
|
|
jpayne@68
|
262 h. Fixed several bugs in the code that calculates line breaks when expanding
|
|
jpayne@68
|
263 prompts that span several lines, contain multibyte characters, and contain
|
|
jpayne@68
|
264 invisible character seqeuences.

jpayne@68
|
268
|
|
jpayne@68
|
269 j. When performing case-insensitive completion, Readline no longer sorts the
|
|
jpayne@68

270 list of matches unless directed to do so.
|
|
jpayne@68
|
271
|
|

|
|
jpayne@68
|
277
|
|
jpayne@68
|
278 n. Fixed a problem with the case-changing operators in the case where the
|
|
jpayne@68
|
279 lower and upper case versions of a character do not have the same number
|
|
jpayne@68
|
280 of bytes.

281
|
|
jpayne@68

|
|
jpayne@68
|
285 sequence could be misinterpreted.
|
|
jpayne@68
|
286
|
|
jpayne@68
|
287 q. The history library now prints a meaningful error message if the history
|
|
jpayne@68
|
288 file isn't a regular file.
|
|
jpayne@68
|
289
|
|
jpayne@68
|
290 r. Fixed a problem with vi-mode redo (`.') on a command when trying to replace
|
|
jpayne@68
|
291 a multibyte character.
|
|
jpayne@68
|
292
|
|
jpayne@68
|
293 s. The key binding code now attempts to remove a keymap if a key unbinding

|
|
jpayne@68
|
301
|
|
jpayne@68
|
302 v. Fixed a problem with exiting bracketed paste mode on terminals that assume
|
|
jpayne@68

|
|
jpayne@68
|
307
|
|
jpayne@68
|

|
|
jpayne@68
|
309 existing functions if the current locale uses UTF-8 encoding.
|
|
jpayne@68
|
310
|
|
jpayne@68
|
311 y. Fixed a problem with bracketed-paste inserting more than one character and

|
|
jpayne@68
|
313
|
|
jpayne@68
|
314 z. Fixed a bug that caused the history library to attempt to append a history
|
|
jpayne@68
|
315 line to a non-existent history entry.
|
|
jpayne@68
|
316
|
|
jpayne@68
|
317 aa. If using bracketed paste mode, output a newline after the \r that is the
|
|
jpayne@68
|
318 last character of the mode disable string to avoid overwriting output.
|
|
jpayne@68
|
319
|
|
jpayne@68
|
320 bb. Fixes to the vi-mode `b', `B', `w', `W', `e', and `E' commands to better

321 handle multibyte characters.
|
|
jpayne@68
|
322
|
|
jpayne@68
|
323 cc. Fixed a redisplay problem that caused an extra newline to be generated on
|
|
jpayne@68
|
324 accept-line when the line length is exactly the screenwidth.
|
|
jpayne@68
|
325
|
|
jpayne@68
|
326 dd. Fixed a bug with adding multibyte characters to an incremental search
|
|
jpayne@68

|
|
jpayne@68
|
330
|
|
jpayne@68
|
331 ff. Fixed a bug with pasting text into an incremental search string if bracketed
|
|
jpayne@68
|
332 paste mode is enabled. ESC cannot be one of the incremental search
|
|
jpayne@68
|
333 terminator characters for this to work.
|
|
jpayne@68
|
334
|
|
jpayne@68

|
|
jpayne@68
|
337
|
|
jpayne@68
|
338 2. New Features in Readline
|
|
jpayne@68
|
339
|
|
jpayne@68
|
340 a. Non-incremental vi-mode search (`N', `n') can search for a shell pattern, as
|
|
jpayne@68
|
341 Posix specifies (uses fnmatch(3) if available).
|
|
jpayne@68
|
342
|
|
jpayne@68
|
343 b. There are new `next-screen-line' and `previous-screen-line' bindable
|
|
jpayne@68
|
344 commands, which move the cursor to the same column in the next, or previous,
|
|
jpayne@68
|
345 physical line, respectively.
|
|
jpayne@68
|
346
|
|
jpayne@68
|
347 c. There are default key bindings for control-arrow-key key combinations.
|
|
jpayne@68
|
348
|
|
jpayne@68
|
349 d. A negative argument (-N) to `quoted-insert' means to insert the next N
|
|
jpayne@68
|
350 characters using quoted-insert.
|
|
jpayne@68
|
351
|
|
jpayne@68
|
352 e. New public function: rl_check_signals(), which allows applications to
|
|
jpayne@68
|
353 respond to signals that readline catches while waiting for input using
|
|
jpayne@68
|
354 a custom read function.
|
|
jpayne@68
|
355
|
|
jpayne@68
|
356 f. There is new support for conditionally testing the readline version in an
|
|
jpayne@68
|
357 inputrc file, with a full set of arithmetic comparison operators available.
|
|
jpayne@68
|
358
|
|
jpayne@68
|
359 g. There is a simple variable comparison facility available for use within an
|
|
jpayne@68
|
360 inputrc file. Allowable operators are equality and inequality; string
|
|
jpayne@68
|
361 variables may be compared to a value; boolean variables must be compared to
|
|
jpayne@68
|
362 either `on' or `off'; variable names are separated from the operator by
|
|
jpayne@68
|
363 whitespace.
|
|
jpayne@68
|
364
|
|
jpayne@68
|
365 h. The history expansion library now understands command and process
|
|
jpayne@68
|
366 substitution and extended globbing and allows them to appear anywhere in a
|
|
jpayne@68
|
367 word.
|
|
jpayne@68
|
368
|
|
jpayne@68
|
369 i. The history library has a new variable that allows applications to set the
|
|
jpayne@68
|
370 initial quoting state, so quoting state can be inherited from a previous
|
|
jpayne@68
|
371 line.
|
|
jpayne@68
|
372
|
|
jpayne@68
|
373 j. Readline now allows application-defined keymap names; there is a new public
|
|
jpayne@68
|
374 function, rl_set_keymap_name(), to do that.
|
|
jpayne@68
|
375
|
|
jpayne@68
|
376 k. The "Insert" keypad key, if available, now puts readline into overwrite
|
|
jpayne@68
|
377 mode.
|
|

|
380 This document details the changes between this version, readline-7.0, and the
|
|
jpayne@68
|
381 previous version, readline-6.3.
|
|
jpayne@68
|
382
|
|
jpayne@68
|
383 1. Changes to Readline
|
|
jpayne@68
|
384
|
|
jpayne@68
|
385 a. A bug that caused vi-mode `.' to be unable to redo `c', `d', and `y'
|
|
jpayne@68
|
386 commands with modifiers was fixed.
|
|
jpayne@68
|
387
|
|
jpayne@68
|
388 b. Fixed a bug that caused callback mode to dump core when reading a
|
|
jpayne@68
|
389 multiple-key sequence (e.g., arrow keys).
|
|
jpayne@68
|
390
|
|
jpayne@68
|
391 c. Fixed a bug that caused the redisplay code to erase some of the line when
|
|
jpayne@68
|
392 using horizontal scrolling with incremental search.
|
|
jpayne@68
|
393
|
|
jpayne@68
|
394 d. Readline's input handler now performs signal processing if read(2) is
|
|
jpayne@68
|
395 interrupted by SIGALRM or SIGVTALRM.
|
|
jpayne@68
|
396
|
|
jpayne@68
|
397 e. Fixed a problem with revert-all-at-newline freeing freed memory.
|
|
jpayne@68
|
398
|
|
jpayne@68
|
399 f. Clarified the documentation for the history_quotes_inhibit_expansion
|
|
jpayne@68
|
400 variable to note that it inhibits scanning for the history comment
|
|
jpayne@68
|
401 character and that it only affects double-quoted strings.
|
|
jpayne@68
|
402
|
|
jpayne@68
|
403 g. Fixed an off-by-one error in the prompt printed when performing searches.
|
|
jpayne@68
|
404
|
|
jpayne@68
|
405 h. Use pselect(2), if available, to wait for input before calling read(2), so
|
|
jpayne@68
|
406 a SIGWINCH can interrupt it, since it doesn't interrupt read(2).
|
|
jpayne@68
|
407
|
|
jpayne@68
|
408 i. Some memory leaks caused by signals interrupting filename completion have
|
|
jpayne@68
|
409 been fixed.
|
|
jpayne@68
|
410
|
|
jpayne@68
|
411 j. Reading EOF twice on a non-empty line causes EOF to be returned, rather
|
|
jpayne@68
|
412 than the partial line. This can cause partial lines to be executed on
|
|
jpayne@68
|
413 SIGHUP, for example.
|
|
jpayne@68
|
414
|
|
jpayne@68
|
415 k. Fixed a bug concerning deleting multibyte characters from the search
|
|
jpayne@68
|
416 string while performing an incremental search.
|
|
jpayne@68
|
417
|
|
jpayne@68
|
418 l. Fixed a bug with tilde expanding directory names in filename completion.
|
|
jpayne@68
|
419
|
|
jpayne@68
|
420 m. Fixed a bug that did not allow binding sequences beginning with a `\'.
|
|
jpayne@68
|
421
|
|
jpayne@68
|
422 n. Fixed a redisplay bug involving incorrect line wrapping when the prompt
|
|
jpayne@68
|
423 contains a multibyte character in the last screen column.
|
|
jpayne@68
|
424
|
|
jpayne@68
|
425 o. Fixed a bug that caused history expansion to disregard characters that are
|
|
jpayne@68
|
426 documented to delimit a history event specifier without requiring `:'.
|
|
jpayne@68
|
427
|
|
jpayne@68
|
428 p. Fixed a bug that could cause reading past the end of a string when reading
|
|
jpayne@68
|
429 the value when binding the set of isearch terminators.
|
|
jpayne@68
|
430
|
|
jpayne@68
|
431 q. Fixed a bug that caused readline commands that depend on knowing which
|
|
jpayne@68
|
432 key invoked them to misbehave when dispatching key sequences that are
|
|
jpayne@68
|
433 prefixes of other key bindings.
|
|
jpayne@68
|
434
|
|
jpayne@68
|
435 r. Paren matching now works in vi insert mode.
|
|
jpayne@68
|
436
|
|
jpayne@68
|
437 s. Colored completion prefixes are now displayed using a different color, less
|
|
jpayne@68
|
438 likely to collide with files.
|
|
jpayne@68
|
439
|
|
jpayne@68
|
440 t. Fixed a bug that caused vi-mode character search to misbehave when
|
|
jpayne@68
|
441 running in callback mode.
|
|
jpayne@68
|
442
|
|
jpayne@68
|
443 u. Fixed a bug that caused output to be delayed when input is coming from a
|
|
jpayne@68
|
444 macro in vi-mode.
|
|
jpayne@68
|
445
|
|
jpayne@68
|
446 v. Fixed a bug that caused the vi-mode `.' command to misbehave when redoing
|
|
jpayne@68
|
447 a multi-key key sequence via a macro.
|
|
jpayne@68
|
448
|
|
jpayne@68
|
449 w. Fixed a bug that caused problems with applications that supply their own
|
|
jpayne@68
|
450 input function when performing completion.
|
|
jpayne@68
|
451
|
|
jpayne@68
|
452 x. When read returns -1/EIO when attempting to read a key, return an error
|
|
jpayne@68
|
453 instead of line termination back to the caller.
|
|
jpayne@68
|
454
|
|
jpayne@68
|
455 y. Updated tty auditing feature based on patch from Red Hat.
|
|
jpayne@68
|
456
|
|
jpayne@68
|
457 z. Fixed a bug that could cause the history library to crash on overflows
|
|
jpayne@68
|
458 introduced by malicious editing of timestamps in the history file.
|
|
jpayne@68
|
459
|
|
jpayne@68
|
460 aa. The history file writing functions only attempt to create and use a backup
|
|
jpayne@68
|
461 history file if the history file exists and is a regular file.
|
|
jpayne@68
|
462
|
|
jpayne@68
|
463 bb. Fixed an out-of-bounds read in readline's internal tilde expansion interface.
|
|
jpayne@68
|
464
|
|
jpayne@68
|
465 cc. Fixed several redisplay bugs with prompt strings containing multibyte
|
|
jpayne@68
|
466 and non-visible characters whose physical length is longer than the screen
|
|
jpayne@68
|
467 width.
|
|
jpayne@68
|
468
|
|
jpayne@68
|
469 dd. Fixed a redisplay bug with prompt strings containing invisible characters
|
|
jpayne@68
|
470 whose physical length exceeds the screen width and using incremental search.
|
|
jpayne@68
|
471
|
|
jpayne@68
|
472 ee. Readline prints more descriptive error messages when it encounters errors
|
|
jpayne@68
|
473 while reading an inputrc file.
|
|
jpayne@68
|
474
|
|
jpayne@68
|
475 ff. Fixed a bug in the character insertion code that attempts to optimize
|
|
jpayne@68
|
476 typeahead when it reads a character that is not bound to self-insert and
|
|
jpayne@68
|
477 resets the key sequence state.
|
|
jpayne@68
|
478
|
|
jpayne@68
|
479 gg. When refreshing the line as the result of a key sequence, Readline attempts
|
|
jpayne@68
|
480 to redraw only the last line of a multiline prompt.
|
|
jpayne@68
|
481
|
|
jpayne@68
|
482 hh. Fixed an issue that caused completion of git commands to display
|
|
jpayne@68
|
483 incorrectly when using colored-completion-prefix.
|
|
jpayne@68
|
484
|
|
jpayne@68
|
485 ii. Fixed several redisplay bugs having to do with multibyte characters and
|
|
jpayne@68
|
486 invisible characters in prompt strings.
|
|
jpayne@68
|
487
|
|
jpayne@68
|
488 jj. Fixed a bug that caused mode strings to be displayed incorrectly if the
|
|
jpayne@68
|
489 prompt was shorter than the mode string.
|
|
jpayne@68
|
490
|
|
jpayne@68
|
491 2. New Features in Readline
|
|
jpayne@68
|
492
|
|
jpayne@68
|
493 a. The history truncation code now uses the same error recovery mechanism as
|
|
jpayne@68
|
494 the history writing code, and restores the old version of the history file
|
|
jpayne@68
|
495 on error. The error recovery mechanism handles symlinked history files.
|
|
jpayne@68
|
496
|
|
jpayne@68
|
497 b. There is a new bindable variable, `enable-bracketed-paste', which enables
|
|
jpayne@68
|
498 support for a terminal's bracketed paste mode.
|
|
jpayne@68
|
499
|
|
jpayne@68
|
500 c. The editing mode indicators can now be strings and are user-settable
|
|
jpayne@68
|
501 (new `emacs-mode-string', `vi-cmd-mode-string' and `vi-ins-mode-string'
|
|
jpayne@68
|
502 variables). Mode strings can contain invisible character sequences.
|
|
jpayne@68
|
503 Setting mode strings to null strings restores the defaults.
|
|
jpayne@68
|
504
|
|
jpayne@68
|
505 d. Prompt expansion adds the mode string to the last line of a multi-line
|
|
jpayne@68
|
506 prompt (one with embedded newlines).
|
|
jpayne@68
|
507
|
|
jpayne@68
|
508 e. There is a new bindable variable, `colored-completion-prefix', which, if
|
|
jpayne@68
|
509 set, causes the common prefix of a set of possible completions to be
|
|
jpayne@68
|
510 displayed in color.
|
|
jpayne@68
|
511
|
|
jpayne@68
|
512 f. There is a new bindable command `vi-yank-pop', a vi-mode version of emacs-
|
|
jpayne@68
|
513 mode yank-pop.
|
|
jpayne@68
|
514
|
|
jpayne@68
|
515 g. The redisplay code underwent several efficiency improvements for multibyte
|
|
jpayne@68
|
516 locales.
|
|
jpayne@68
|
517
|
|
jpayne@68
|
518 h. The insert-char function attempts to batch-insert all pending typeahead
|
|
jpayne@68
|
519 that maps to self-insert, as long as it is coming from the terminal.
|
|
jpayne@68
|
520
|
|
jpayne@68
|
521 i. rl_callback_sigcleanup: a new application function that can clean up and
|
|
jpayne@68
|
522 unset any state set by readline's callback mode. Intended to be used
|
|
jpayne@68
|
523 after a signal.
|
|
jpayne@68
|
524
|
|
jpayne@68
|
525 j. If an incremental search string has its last character removed with DEL, the
|
|
jpayne@68
|
526 resulting empty search string no longer matches the previous line.
|
|
jpayne@68
|
527
|
|
jpayne@68
|
528 k. If readline reads a history file that begins with `#' (or the value of
|
|
jpayne@68
|
529 the history comment character) and has enabled history timestamps, the history
|
|
jpayne@68
|
530 entries are assumed to be delimited by timestamps. This allows multi-line
|
|
jpayne@68
|
531 history entries.
|
|
jpayne@68
|
532
|
|
jpayne@68
|
533 l. Readline now throws an error if it parses a key binding without a terminating
|
|
jpayne@68
|
534 `:' or whitespace.
|
|
jpayne@68
|
535
|
|
jpayne@68
|
536 m. The default binding for ^W in vi mode now uses word boundaries specified
|
|
jpayne@68
|
537 by Posix (vi-unix-word-rubout is bindable command name).
|
|
jpayne@68
|
538
|
|
jpayne@68
|
539 n. rl_clear_visible_line: new application-callable function; clears all
|
|
jpayne@68
|
540 screen lines occupied by the current visible readline line.
|
|
jpayne@68
|
541
|
|
jpayne@68
|
542 o. rl_tty_set_echoing: application-callable function that controls whether
|
|
jpayne@68
|
543 or not readline thinks it is echoing terminal output.
|
|
jpayne@68
|
544
|
|
jpayne@68
|
545 p. Handle >| and strings of digits preceding and following redirection
|
|
jpayne@68
|
546 specifications as single tokens when tokenizing the line for history
|
|
jpayne@68
|
547 expansion.
|
|
jpayne@68
|
548
|
|
jpayne@68
|
549 q. Fixed a bug with displaying completions when the prefix display length
|
|
jpayne@68
|
550 is greater than the length of the completions to be displayed.
|
|
jpayne@68
|
551
|
|
jpayne@68
|
552 r. The :p history modifier now applies to the entire line, so any expansion
|
|
jpayne@68
|
553 specifying :p causes the line to be printed instead of expanded.
|
|
jpayne@68
|
554
|
|
jpayne@68
|
555 s. New application-callable function: rl_pending_signal(): returns the signal
|
|
jpayne@68
|
556 number of any signal readline has caught but not yet handled.
|
|
jpayne@68
|
557
|
|
jpayne@68
|
558 t. New application-settable variable: rl_persistent_signal_handlers: if set
|
|
jpayne@68
|
559 to a non-zero value, readline will enable the readline-6.2 signal handler
|
|
jpayne@68
|
560 behavior in callback mode: handlers are installed when
|
|
jpayne@68
|
561 rl_callback_handler_install is called and removed removed when a complete
|
|
jpayne@68
|
562 line has been read.

566 previous version, readline-6.2.
|
|
jpayne@68
|
567
|
|
jpayne@68
|
568 1. Changes to Readline
|
|
jpayne@68
|
569
|
|
jpayne@68
|
570 a. Fixed a bug that did not allow the `dd', `cc', or `yy' vi editing mode
|
|
jpayne@68
|
571 commands to work on the entire line.
|
|
jpayne@68
|
572
|
|
jpayne@68
|
573 b. Fixed a bug that caused redisplay problems with prompts longer than 128
|
|
jpayne@68
|
574 characters and history searches.
|
|
jpayne@68
|
575
|
|
jpayne@68
|
576 c. Fixed a bug that caused readline to try and run code to modify its idea
|
|
jpayne@68
|
577 of the screen size in a signal handler context upon receiving a SIGWINCH.
|
|
jpayne@68
|
578
|
|
jpayne@68
|
579 d. Fixed a bug that caused the `meta' key to be enabled beyond the duration
|
|
jpayne@68
|
580 of an individual call top readline().
|
|
jpayne@68
|
581
|
|
jpayne@68
|
582 e. Added a workaround for a wcwidth bug in Mac OS X that caused readline's
|
|
jpayne@68
|
583 redisplay to mishandle zero-width combining characters.
|
|
jpayne@68
|
584
|
|
jpayne@68
|
585 f. Fixed a bug that caused readline to `forget' part of a key sequence when
|
|
jpayne@68
|
586 a multiple-key sequence caused it to break out of an incremental search.
|
|
jpayne@68
|
587
|
|
jpayne@68
|
588 g. Fixed bugs that caused readline to execute code in a signal handler
|
|
jpayne@68
|
589 context if interrupted while reading from the file system during completion.
|
|
jpayne@68
|
590
|
|
jpayne@68
|
591 h. Fixed a bug that caused readline to `forget' part of a key sequence when
|
|
jpayne@68
|
592 reading an unbound multi-character key sequence.
|
|
jpayne@68
|
593
|
|
jpayne@68
|
594 i. Fixed a bug that caused Readline's signal handlers to be installed beyond
|
|
jpayne@68
|
595 the bounds of a single call to readline().
|
|
jpayne@68
|
596
|
|
jpayne@68
|
597 j. Fixed a bug that caused the `.' command to not redo the most recent `R'
|
|
jpayne@68
|
598 command in vi mode.
|
|
jpayne@68
|
599
|
|
jpayne@68
|
600 k. Fixed a bug that caused ignoring case in completion matches to result in
|
|
jpayne@68
|
601 readline using the wrong match.
|
|
jpayne@68
|
602
|
|
jpayne@68
|
603 l. Paren matching now works in vi insert mode.
|
|
jpayne@68
|
604
|
|
jpayne@68
|
605 m. Fix menu-completion to make show-all-if-ambiguous and menu-complete-display-prefix
|
|
jpayne@68
|
606 work together.
|
|
jpayne@68
|
607
|
|
jpayne@68
|
608 n. Fixed a bug that didn't allow the `cc', `dd', or `yy' commands to be redone
|
|
jpayne@68
|
609 in vi editing mode.
|
|
jpayne@68
|
610
|
|
jpayne@68
|
611 o. Fixed a bug that caused the filename comparison code to not compare
|
|
jpayne@68
|
612 multibyte characters correctly when using case-sensitive or case-mapping
|
|
jpayne@68
|
613 comparisons.
|
|
jpayne@68
|
614
|
|
jpayne@68
|
615 p. Fixed the input reading loop to call the input hook function only when there
|
|
jpayne@68
|
616 is no terminal input available.
|
|
jpayne@68
|
617
|
|
jpayne@68
|
618 q. Fixed a bug that caused binding a macro to a multi-character key sequence
|
|
jpayne@68
|
619 where the sequence and macro value share a common prefix to not perform
|
|
jpayne@68
|
620 the macro replacement.
|
|
jpayne@68
|
621
|
|
jpayne@68
|
622 r. Fixed several redisplay errors with multibyte characters and prompts
|
|
jpayne@68
|
623 containing invisible characters when using horizontal scrolling.
|
|
jpayne@68
|
624
|
|
jpayne@68
|
625 s. Fixed a bug that caused redisplay errors when trying to overwrite
|
|
jpayne@68
|
626 existing characters using multibyte characters.
|
|
jpayne@68
|
627
|
|
jpayne@68
|
628 t. Fixed a bug in vi mode that caused the arrow keys to set the saved last
|
|
jpayne@68
|
629 vi-mode command to the wrong value.
|
|
jpayne@68
|
630
|
|
jpayne@68
|
631 u. Fixed a bug that caused double-quoted strings to be scanned incorrectly
|
|
jpayne@68
|
632 when being used as the value of a readline variable assignment.
|
|
jpayne@68
|
633
|
|
jpayne@68
|
634 v. Fixed a bug with vi mode that prevented `.' from repeating a command
|
|
jpayne@68
|
635 entered on a previous line (command).
|
|
jpayne@68
|
636
|
|
jpayne@68
|
637 w. Fixed a bug that could cause completion to core dump if it was interrupted
|
|
jpayne@68
|
638 by a signal.
|
|
jpayne@68
|
639
|
|
jpayne@68
|
640 x. Fixed a bug that could cause readline to crash and seg fault attempting to
|
|
jpayne@68
|
641 expand an empty history entry.
|
|
jpayne@68
|
642
|
|
jpayne@68
|
643 y. Fixed a bug that caused display problems with multi-line prompts containing
|
|
jpayne@68
|
644 invisible characters on multiple lines.
|
|
jpayne@68
|
645
|
|
jpayne@68
|
646 z. Fixed a bug that caused effects made by undoing changes to a history line to
|
|
jpayne@68
|
647 be discarded.
|
|
jpayne@68
|
648
|
|
jpayne@68
|
649 2. New Features in Readline
|
|
jpayne@68
|
650
|
|
jpayne@68
|
651 a. Readline is now more responsive to SIGHUP and other fatal signals when
|
|
jpayne@68
|
652 reading input from the terminal or performing word completion but no
|
|
jpayne@68
|
653 longer attempts to run any not-allowable functions from a signal handler
|
|
jpayne@68
|
654 context.
|
|
jpayne@68
|
655
|
|
jpayne@68
|
656 b. There are new bindable commands to search the history for the string of
|
|
jpayne@68
|
657 characters between the beginning of the line and the point
|
|
jpayne@68
|
658 (history-substring-search-forward, history-substring-search-backward)
|
|
jpayne@68
|
659
|
|
jpayne@68
|
660 c. Readline allows quoted strings as the values of variables when setting
|
|
jpayne@68
|
661 them with `set'. As a side effect, trailing spaces and tabs are ignored
|
|
jpayne@68
|
662 when setting a string variable's value.
|
|
jpayne@68
|
663
|
|
jpayne@68
|
664 d. The history library creates a backup of the history file when writing it
|
|
jpayne@68
|
665 and restores the backup on a write error.
|
|
jpayne@68
|
666
|
|
jpayne@68
|
667 e. New application-settable variable: rl_filename_stat_hook: a function called
|
|
jpayne@68
|
668 with a filename before using it in a call to stat(2). Bash uses it to
|
|
jpayne@68
|
669 expand shell variables so things like $HOME/Downloads have a slash
|
|
jpayne@68
|
670 appended.
|
|
jpayne@68
|
671
|
|
jpayne@68
|
672 f. New bindable function `print-last-kbd-macro', prints the most-recently-
|
|
jpayne@68
|
673 defined keyboard macro in a reusable format.
|
|
jpayne@68
|
674
|
|
jpayne@68
|
675 g. New user-settable variable `colored-stats', enables use of colored text
|
|
jpayne@68
|
676 to denote file types when displaying possible completions (colored analog
|
|
jpayne@68
|
677 of visible-stats).
|
|
jpayne@68
|
678
|
|
jpayne@68
|
679 h. New user-settable variable `keyseq-timout', acts as an inter-character
|
|
jpayne@68
|
680 timeout when reading input or incremental search strings.
|
|
jpayne@68
|
681
|
|
jpayne@68
|
682 i. New application-callable function: rl_clear_history. Clears the history list
|
|
jpayne@68
|
683 and frees all readline-associated private data.
|
|
jpayne@68
|
684
|
|
jpayne@68
|
685 j. New user-settable variable, show-mode-in-prompt, adds a characters to the
|
|
jpayne@68
|
686 beginning of the prompt indicating the current editing mode.
|
|
jpayne@68
|
687
|
|
jpayne@68
|
688 k. New application-settable variable: rl_input_available_hook; function to be
|
|
jpayne@68
|
689 called when readline needs to check whether there is data available on its
|
|
jpayne@68
|
690 input source. The default hook checks rl_instream.
|
|
jpayne@68
|
691
|
|
jpayne@68
|
692 l. Readline calls an application-set event hook (rl_signal_event_hook) after
|
|
jpayne@68
|
693 it gets a signal while reading input (read returns -1/EINTR but readline
|
|
jpayne@68
|
694 does not handle the signal immediately) to allow the application to handle
|
|
jpayne@68
|
695 or otherwise note it. Not currently called for SIGHUP or SIGTERM.
|
|
jpayne@68
|
696
|
|
jpayne@68
|
697 m. If the user-settable variable `history-size' is set to a value less than
|
|
jpayne@68
|
698 0, the history list size is unlimited.
|
|
jpayne@68
|
699
|
|
jpayne@68
|
700 n. When creating shared libraries on Mac OS X, the pathname written into the
|
|
jpayne@68
|
701 library (install_name) no longer includes the minor version number.
|
|
jpayne@68
|
702

704 This document details the changes between this version, readline-6.2,
|
|
jpayne@68
|
705 and the previous version, readline-6.1.
|
|
jpayne@68
|
706
|
|
jpayne@68
|
707 1. Changes to Readline
|
|
jpayne@68
|
708
|
|
jpayne@68
|
709 a. Fixed a bug that caused the unconverted filename to be added to the list of
|
|
jpayne@68
|
710 completions when the application specified filename conversion functions.
|
|
jpayne@68
|
711
|
|
jpayne@68
|
712 b. Fixed a bug that caused the wrong filename to be passed to opendir when the
|
|
jpayne@68
|
713 application has specified a filename dequoting function.
|
|
jpayne@68
|
714
|
|
jpayne@68
|
715 c. Fixed a bug when repeating a character search in vi mode in the case where
|
|
jpayne@68
|
716 there was no search to repeat.
|
|
jpayne@68
|
717
|
|
jpayne@68
|
718 d. When show-all-if-ambiguous is set, the completion routines no longer insert
|
|
jpayne@68
|
719 a common match prefix that is shorter than the text being completed.
|
|
jpayne@68
|
720
|
|
jpayne@68
|
721 e. The full set of vi editing commands may now be used in callback mode.
|
|
jpayne@68
|
722
|
|
jpayne@68
|
723 f. Fixed a bug that caused readline to not update its idea of the terminal
|
|
jpayne@68
|
724 dimensions while running in `no-echo' mode.
|
|
jpayne@68
|
725
|
|
jpayne@68
|
726 h. Fixed a bug that caused readline to dump core if an application called
|
|
jpayne@68
|
727 rl_prep_terminal without setting rl_instream.
|
|
jpayne@68
|
728
|
|
jpayne@68
|
729 i. Fixed a bug that caused meta-prefixed characters bound to incremental
|
|
jpayne@68
|
730 search forward or backward to not be recognized if they were typed
|
|
jpayne@68
|
731 subsequently.
|
|
jpayne@68
|
732
|
|
jpayne@68
|
733 j. The incremental search code treats key sequences that map to the same
|
|
jpayne@68
|
734 functions as (default) ^G, ^W, and ^Y as equivalent to those characters.
|
|
jpayne@68
|
735
|
|
jpayne@68
|
736 k. Fixed a bug in menu-complete that caused it to misbehave with large
|
|
jpayne@68
|
737 negative argument.
|
|
jpayne@68
|
738
|
|
jpayne@68
|
739 l. Fixed a bug that caused vi-mode yank-last-arg to ring the bell when invoked
|
|
jpayne@68
|
740 at the end of the line.
|
|
jpayne@68
|
741
|
|
jpayne@68
|
742 m. Fixed a bug that made an explicit argument of 0 to yank-last-arg behave
|
|
jpayne@68
|
743 as if it were a negative argument.
|
|
jpayne@68
|
744
|
|
jpayne@68
|
745 n. Fixed a bug that caused directory names in words to be completed to not
|
|
jpayne@68
|
746 be dequoted correctly.
|
|
jpayne@68
|
747
|
|
jpayne@68
|
748 2. New Features in Readline
|
|
jpayne@68
|
749
|
|
jpayne@68
|
750 a. The history library does not try to write the history filename in the
|
|
jpayne@68
|
751 current directory if $HOME is unset. This closes a potential security
|
|
jpayne@68
|
752 problem if the application does not specify a history filename.
|
|
jpayne@68
|
753
|
|
jpayne@68
|
754 b. New bindable variable `completion-display-width' to set the number of
|
|
jpayne@68
|
755 columns used when displaying completions.
|
|
jpayne@68
|
756
|
|
jpayne@68
|
757 c. New bindable variable `completion-case-map' to cause case-insensitive
|
|
jpayne@68
|
758 completion to treat `-' and `_' as identical.
|
|
jpayne@68
|
759
|
|
jpayne@68
|
760 d. There are new bindable vi-mode command names to avoid readline's case-
|
|
jpayne@68
|
761 insensitive matching not allowing them to be bound separately.
|
|
jpayne@68
|
762
|
|
jpayne@68
|
763 e. New bindable variable `menu-complete-display-prefix' causes the menu
|
|
jpayne@68
|
764 completion code to display the common prefix of the possible completions
|
|
jpayne@68
|
765 before cycling through the list, instead of after.
|
|
jpayne@68
|
766

768 This document details the changes between this version, readline-6.1,
|
|
jpayne@68
|
769 and the previous version, readline-6.0.
|
|
jpayne@68
|
770
|
|
jpayne@68
|
771 1. Changes to Readline
|
|
jpayne@68
|
772
|
|
jpayne@68
|
773 a. The SIGWINCH signal handler now avoids calling the redisplay code if
|
|
jpayne@68
|
774 one arrives while in the middle of redisplay.
|
|
jpayne@68
|
775
|
|
jpayne@68
|
776 b. Changes to the timeout code to make sure that timeout values greater
|
|
jpayne@68
|
777 than one second are handled better.
|
|
jpayne@68
|
778
|
|
jpayne@68
|
779 c. Fixed a bug in the redisplay code that was triggered by a prompt
|
|
jpayne@68
|
780 containing invisible characters exactly the width of the screen.
|
|
jpayne@68
|
781
|
|
jpayne@68
|
782 d. Fixed a bug in the redisplay code encountered when running in horizontal
|
|
jpayne@68
|
783 scroll mode.
|
|
jpayne@68
|
784
|
|
jpayne@68
|
785 e. Fixed a bug that prevented menu completion from properly completing
|
|
jpayne@68
|
786 filenames.
|
|
jpayne@68
|
787
|
|
jpayne@68
|
788 f. Fixed a redisplay bug caused by a multibyte character causing a line to
|
|
jpayne@68
|
789 wrap.
|
|
jpayne@68
|
790
|
|
jpayne@68
|
791 g. Fixed a bug that caused key sequences of two characters to not be
|
|
jpayne@68
|
792 recognized when a longer sequence identical in the first two characters
|
|
jpayne@68
|
793 was bound.
|
|
jpayne@68
|
794
|
|
jpayne@68
|
795 h. Fixed a bug that caused history expansion to be attempted on $'...'
|
|
jpayne@68
|
796 single-quoted strings.
|
|
jpayne@68
|
797
|
|
jpayne@68
|
798 i. Fixed a bug that caused incorrect redisplay when the prompt contained
|
|
jpayne@68
|
799 multibyte characters in an `invisible' sequence bracketed by \[ and
|
|
jpayne@68
|
800 \].
|
|
jpayne@68
|
801
|
|
jpayne@68
|
802 j. Fixed a bug that caused history expansion to short-circuit after
|
|
jpayne@68
|
803 encountering a multibyte character.
|
|
jpayne@68
|
804
|
|
jpayne@68
|
805 k. Fixed a bug that caused applications using the callback interface to not
|
|
jpayne@68
|
806 react to SIGINT (or other signals) until another character arrived.
|
|
jpayne@68
|
807
|
|
jpayne@68
|
808 2. New Features in Readline
|
|
jpayne@68
|
809
|
|
jpayne@68
|
810 a. New bindable function: menu-complete-backward.
|
|
jpayne@68
|
811
|
|
jpayne@68
|
812 b. In the vi insertion keymap, C-n is now bound to menu-complete by default,
|
|
jpayne@68
|
813 and C-p to menu-complete-backward.
|
|
jpayne@68
|
814
|
|
jpayne@68
|
815 c. When in vi command mode, repeatedly hitting ESC now does nothing, even
|
|
jpayne@68
|
816 when ESC introduces a bound key sequence. This is closer to how
|
|
jpayne@68
|
817 historical vi behaves.
|
|
jpayne@68
|
818
|
|
jpayne@68
|
819 d. New bindable function: skip-csi-sequence. Can be used as a default to
|
|
jpayne@68
|
820 consume key sequences generated by keys like Home and End without having
|
|
jpayne@68
|
821 to bind all keys.
|
|
jpayne@68
|
822
|
|
jpayne@68
|
823 e. New application-settable function: rl_filename_rewrite_hook. Can be used
|
|
jpayne@68
|
824 to rewrite or modify filenames read from the file system before they are
|
|
jpayne@68
|
825 compared to the word to be completed.
|
|
jpayne@68
|
826
|
|
jpayne@68
|
827 f. New bindable variable: skip-completed-text, active when completing in the
|
|
jpayne@68
|
828 middle of a word. If enabled, it means that characters in the completion
|
|
jpayne@68
|
829 that match characters in the remainder of the word are "skipped" rather
|
|
jpayne@68
|
830 than inserted into the line.
|
|
jpayne@68
|
831
|
|
jpayne@68
|
832 g. The pre-readline-6.0 version of menu completion is available as
|
|
jpayne@68
|
833 "old-menu-complete" for users who do not like the readline-6.0 version.
|
|
jpayne@68
|
834
|
|
jpayne@68
|
835 h. New bindable variable: echo-control-characters. If enabled, and the
|
|
jpayne@68
|
836 tty ECHOCTL bit is set, controls the echoing of characters corresponding
|
|
jpayne@68
|
837 to keyboard-generated signals.
|
|
jpayne@68
|
838
|
|
jpayne@68
|
839 i. New bindable variable: enable-meta-key. Controls whether or not readline
|
|
jpayne@68
|
840 sends the smm/rmm sequences if the terminal indicates it has a meta key
|
|
jpayne@68
|
841 that enables eight-bit characters.

844 This document details the changes between this version, readline-6.0,
|
|
jpayne@68
|
845 and the previous version, readline-5.2.
|
|
jpayne@68
|
846
|
|
jpayne@68
|
847 1. Changes to Readline
|
|
jpayne@68
|
848
|
|
jpayne@68
|
849 a. Fixed a number of redisplay errors in environments supporting multibyte
|
|
jpayne@68
|
850 characters.
|
|
jpayne@68
|
851
|
|
jpayne@68
|
852 b. Fixed bugs in vi command mode that caused motion commands to inappropriately
|
|
jpayne@68
|
853 set the mark.
|
|
jpayne@68
|
854
|
|
jpayne@68
|
855 c. When using the arrow keys in vi insertion mode, readline allows movement
|
|
jpayne@68
|
856 beyond the current end of the line (unlike command mode).
|
|
jpayne@68
|
857
|
|
jpayne@68
|
858 d. Fixed bugs that caused readline to loop when the terminal has been taken
|
|
jpayne@68
|
859 away and reads return -1/EIO.
|
|
jpayne@68
|
860
|
|
jpayne@68
|
861 e. Fixed bugs in redisplay occurring when displaying prompts containing
|
|
jpayne@68
|
862 invisible characters.
|
|
jpayne@68
|
863
|
|
jpayne@68
|
864 f. Fixed a bug that caused the completion append character to not be reset to
|
|
jpayne@68
|
865 the default after an application-specified completion function changed it.
|
|
jpayne@68
|
866
|
|
jpayne@68
|
867 g. Fixed a problem that caused incorrect positioning of the cursor while in
|
|
jpayne@68
|
868 emacs editing mode when moving forward at the end of a line while using
|
|
jpayne@68
|
869 a locale supporting multibyte characters.
|
|
jpayne@68
|
870
|
|
jpayne@68
|
871 h. Fixed an off-by-one error that caused readline to drop every 511th
|
|
jpayne@68
|
872 character of buffered input.
|
|
jpayne@68
|
873
|
|
jpayne@68
|
874 i. Fixed a bug that resulted in SIGTERM not being caught or cleaned up.
|
|
jpayne@68
|
875
|
|
jpayne@68
|
876 j. Fixed redisplay bugs caused by multiline prompts with invisible characters
|
|
jpayne@68
|
877 or no characters following the final newline.
|
|
jpayne@68
|
878
|
|
jpayne@68
|
879 k. Fixed redisplay bug caused by prompts consisting solely of invisible
|
|
jpayne@68
|
880 characters.
|
|
jpayne@68
|
881
|
|
jpayne@68
|
882 l. Fixed a bug in the code that buffers characters received very quickly in
|
|
jpayne@68
|
883 succession which caused characters to be dropped.
|
|
jpayne@68
|
884
|
|
jpayne@68
|
885 m. Fixed a bug that caused readline to reference uninitialized data structures
|
|
jpayne@68
|
886 if it received a SIGWINCH before completing initialization.
|
|
jpayne@68
|
887
|
|
jpayne@68
|
888 n. Fixed a bug that caused the vi-mode `last command' to be set incorrectly
|
|
jpayne@68
|
889 and therefore unrepeatable.
|
|
jpayne@68
|
890
|
|
jpayne@68
|
891 o. Fixed a bug that caused readline to disable echoing when it was being used
|
|
jpayne@68
|
892 with an output file descriptor that was not a terminal.
|
|
jpayne@68
|
893
|
|
jpayne@68
|
894 p. Readline now blocks SIGINT while manipulating internal data structures
|
|
jpayne@68
|
895 during redisplay.
|
|
jpayne@68
|
896
|
|
jpayne@68
|
897 q. Fixed a bug in redisplay that caused readline to segfault when pasting a
|
|
jpayne@68
|
898 very long line (over 130,000 characters).
|
|
jpayne@68
|
899
|
|
jpayne@68
|
900 r. Fixed bugs in redisplay when using prompts with no visible printing
|
|
jpayne@68
|
901 characters.
|
|
jpayne@68
|
902
|
|
jpayne@68
|
903 s. Fixed a bug that caused redisplay errors when using prompts with invisible
|
|
jpayne@68
|
904 characters and numeric arguments to a command in a multibyte locale.
|
|
jpayne@68
|
905
|
|
jpayne@68
|
906 t. Fixed a bug that caused redisplay errors when using prompts with invisible
|
|
jpayne@68
|
907 characters spanning more than two physical screen lines.
|
|
jpayne@68
|
908
|
|
jpayne@68
|
909 2. New Features in Readline
|
|
jpayne@68
|
910
|
|
jpayne@68
|
911 a. A new variable, rl_sort_completion_matches; allows applications to inhibit
|
|
jpayne@68
|
912 match list sorting (but beware: some things don't work right if
|
|
jpayne@68
|
913 applications do this).
|
|
jpayne@68
|
914
|
|
jpayne@68
|
915 b. A new variable, rl_completion_invoking_key; allows applications to discover
|
|
jpayne@68
|
916 the key that invoked rl_complete or rl_menu_complete.
|
|
jpayne@68
|
917
|
|
jpayne@68
|
918 c. The functions rl_block_sigint and rl_release_sigint are now public and
|
|
jpayne@68
|
919 available to calling applications who want to protect critical sections
|
|
jpayne@68
|
920 (like redisplay).
|
|
jpayne@68
|
921
|
|
jpayne@68
|
922 d. The functions rl_save_state and rl_restore_state are now public and
|
|
jpayne@68
|
923 available to calling applications; documented rest of readline's state
|
|
jpayne@68
|
924 flag values.
|
|
jpayne@68
|
925
|
|
jpayne@68
|
926 e. A new user-settable variable, `history-size', allows setting the maximum
|
|
jpayne@68
|
927 number of entries in the history list.
|
|
jpayne@68
|
928
|
|
jpayne@68
|
929 f. There is a new implementation of menu completion, with several improvements
|
|
jpayne@68
|
930 over the old; the most notable improvement is a better `completions
|
|
jpayne@68
|
931 browsing' mode.
|
|
jpayne@68
|
932
|
|
jpayne@68
|
933 g. The menu completion code now uses the rl_menu_completion_entry_function
|
|
jpayne@68
|
934 variable, allowing applications to provide their own menu completion
|
|
jpayne@68
|
935 generators.
|
|
jpayne@68
|
936
|
|
jpayne@68
|
937 h. There is support for replacing a prefix of a pathname with a `...' when
|
|
jpayne@68
|
938 displaying possible completions. This is controllable by setting the
|
|
jpayne@68
|
939 `completion-prefix-display-length' variable. Matches with a common prefix
|
|
jpayne@68
|
940 longer than this value have the common prefix replaced with `...'.
|
|
jpayne@68
|
941
|
|
jpayne@68
|
942 i. There is a new `revert-all-at-newline' variable. If enabled, readline will
|
|
jpayne@68
|
943 undo all outstanding changes to all history lines when `accept-line' is
|
|
jpayne@68
|
944 executed.
|
|
jpayne@68
|
945

jpayne@68
|
947 This document details the changes between this version, readline-5.2,
|
|
jpayne@68
|
948 and the previous version, readline-5.1.
|
|
jpayne@68
|
949
|
|
jpayne@68
|
950 1. Changes to Readline
|
|
jpayne@68
|
951
|
|
jpayne@68
|
952 a. Fixed a problem that caused segmentation faults when using readline in
|
|
jpayne@68
|
953 callback mode and typing consecutive DEL characters on an empty line.
|
|
jpayne@68
|
954
|
|
jpayne@68
|
955 b. Fixed several redisplay problems with multibyte characters, all having to
|
|
jpayne@68
|
956 do with the different code paths and variable meanings between single-byte
|
|
jpayne@68
|
957 and multibyte character redisplay.
|
|
jpayne@68
|
958
|
|
jpayne@68
|
959 c. Fixed a problem with key sequence translation when presented with the
|
|
jpayne@68
|
960 sequence \M-\C-x.
|
|
jpayne@68
|
961
|
|
jpayne@68
|
962 d. Fixed a problem that prevented the `a' command in vi mode from being
|
|
jpayne@68
|
963 undone and redone properly.
|
|
jpayne@68
|
964
|
|
jpayne@68
|
965 e. Fixed a problem that prevented empty inserts in vi mode from being undone
|
|
jpayne@68
|
966 properly.
|
|
jpayne@68
|
967
|
|
jpayne@68
|
968 f. Fixed a problem that caused readline to initialize with an incorrect idea
|
|
jpayne@68
|
969 of whether or not the terminal can autowrap.
|
|
jpayne@68
|
970
|
|
jpayne@68
|
971 g. Fixed output of key bindings (like bash `bind -p') to honor the setting of
|
|
jpayne@68
|
972 convert-meta and use \e where appropriate.
|
|
jpayne@68
|
973
|
|
jpayne@68
|
974 h. Changed the default filename completion function to call the filename
|
|
jpayne@68
|
975 dequoting function if the directory completion hook isn't set. This means
|
|
jpayne@68
|
976 that any directory completion hooks need to dequote the directory name,
|
|
jpayne@68
|
977 since application-specific hooks need to know how the word was quoted,
|
|
jpayne@68
|
978 even if no other changes are made.
|
|
jpayne@68
|
979
|
|
jpayne@68
|
980 i. Fixed a bug with creating the prompt for a non-interactive search string
|
|
jpayne@68
|
981 when there are non-printing characters in the primary prompt.
|
|
jpayne@68
|
982
|
|
jpayne@68
|
983 j. Fixed a bug that caused prompts with invisible characters to be redrawn
|
|
jpayne@68
|
984 multiple times in a multibyte locale.
|
|
jpayne@68
|
985
|
|
jpayne@68
|
986 k. Fixed a bug that could cause the key sequence scanning code to return the
|
|
jpayne@68
|
987 wrong function.
|
|
jpayne@68
|
988
|
|
jpayne@68
|
989 l. Fixed a problem with the callback interface that caused it to fail when
|
|
jpayne@68
|
990 using multi-character keyboard macros.
|
|
jpayne@68
|
991
|
|
jpayne@68
|
992 m. Fixed a bug that could cause a core dump when an edited history entry was
|
|
jpayne@68
|
993 re-executed under certain conditions.
|
|
jpayne@68
|
994
|
|
jpayne@68
|
995 n. Fixed a bug that caused readline to reference freed memory when attmpting
|
|
jpayne@68
|
996 to display a portion of the prompt.
|
|
jpayne@68
|
997
|
|
jpayne@68
|
998 o. Fixed a bug with prompt redisplay in a multi-byte locale to avoid redrawing
|
|
jpayne@68
|
999 the prompt and input line multiple times.
|
|
jpayne@68
|
1000
|
|
jpayne@68
|
1001 p. Fixed history expansion to not be confused by here-string redirection.
|
|
jpayne@68
|
1002
|
|
jpayne@68
|
1003 q. Readline no longer treats read errors by converting them to newlines, as
|
|
jpayne@68
|
1004 it does with EOF. This caused partial lines to be returned from readline().
|
|
jpayne@68
|
1005
|
|
jpayne@68
|
1006 r. Fixed a redisplay bug that occurred in multibyte-capable locales when the
|
|
jpayne@68
|
1007 prompt was one character longer than the screen width.
|
|
jpayne@68
|
1008
|
|
jpayne@68
|
1009 2. New Features in Readline
|
|
jpayne@68
|
1010
|
|
jpayne@68
|
1011 a. Calling applications can now set the keyboard timeout to 0, allowing
|
|
jpayne@68
|
1012 poll-like behavior.
|
|
jpayne@68
|
1013
|
|
jpayne@68
|
1014 b. The value of SYS_INPUTRC (configurable at compilation time) is now used as
|
|
jpayne@68
|
1015 the default last-ditch startup file.
|
|
jpayne@68
|
1016
|
|
jpayne@68
|
1017 c. The history file reading functions now allow windows-like \r\n line
|
|
jpayne@68
|
1018 terminators.
|
|
jpayne@68
|
1019
|
|

1021 This document details the changes between this version, readline-5.1,
|
|
jpayne@68
|
1022 and the previous version, readline-5.0.
|
|
jpayne@68
|
1023
|
|
jpayne@68
|
1024 1. Changes to Readline
|
|
jpayne@68
|
1025
|
|
jpayne@68
|
1026 a. Fixed a bug that caused multiliine prompts to be wrapped and displayed
|
|
jpayne@68
|
1027 incorrectly.
|
|
jpayne@68
|
1028
|
|
jpayne@68
|
1029 b. Fixed a bug that caused ^P/^N in emacs mode to fail to display the current
|
|
jpayne@68
|
1030 line correctly.
|
|
jpayne@68
|
1031
|
|
jpayne@68
|
1032 c. Fixed a problem in computing the number of invisible characters on the first
|
|
jpayne@68
|
1033 line of a prompt whose length exceeds the screen width.
|
|
jpayne@68
|
1034
|
|
jpayne@68
|
1035 d. Fixed vi-mode searching so that failure preserves the current line rather
|
|
jpayne@68
|
1036 than the last line in the history list.
|
|
jpayne@68
|
1037
|
|
jpayne@68
|
1038 e. Fixed the vi-mode `~' command (change-case) to have the correct behavior at
|
|
jpayne@68
|
1039 end-of-line when manipulating multibyte characters.
|
|

|
|
jpayne@68
|
1043
|
|
jpayne@68
|
1044 g. Fixed multiple bugs in the redisplay of multibyte characters: displaying
|
|
jpayne@68
|
1045 prompts longer than the screen width containing multibyte characters,
|
|
jpayne@68
|
1046
|
|
jpayne@68
|
1047 h. Fix the calculation of the number of physical characters in the prompt
|
|
jpayne@68
|
1048 string when it contains multibyte characters.
|
|
jpayne@68
|
1049
|
|
jpayne@68
|
1050 i. A non-zero value for the `rl_complete_suppress_append' variable now causes
|
|
jpayne@68
|
1051 no `/' to be appended to a directory name.
|
|
jpayne@68
|
1052
|
|
jpayne@68
|
1053 j. Fixed forward-word and backward-word to work when words contained
|
|
jpayne@68

1054 multibyte characters.
|
|
jpayne@68
|
1055
|
|
jpayne@68

|
|
jpayne@68
|
1060
|
|
jpayne@68

1061 m. Fixed a bug that caused "\M-x" style key bindings to not obey the setting
|
|
jpayne@68
|
1062 of the `convert-meta' variable.
|
|
jpayne@68
|
1063
|
|
jpayne@68
|
1064 n. Fixed saving and restoring primary prompt when prompting for incremental
|
|
jpayne@68
|
1065 and non-incremental searches; search prompts now display multibyte
|
|
jpayne@68
|
1066 characters correctly.
|
|
jpayne@68
|
1067
|
|
jpayne@68
|
1068 o. Fixed a bug that caused keys originally bound to self-insert but shadowed
|
|
jpayne@68
|
1069 by a multi-character key sequence to not be inserted.
|
|
jpayne@68
|
1070
|
|
jpayne@68
|
1071 p. Fixed code so rl_prep_term_function and rl_deprep_term_function aren't
|
|
jpayne@68
|
1072 dereferenced if NULL (matching the documentation).
|
|
jpayne@68
|
1073
|
|
jpayne@68
|
1074 q. Extensive changes to readline to add enough state so that commands
|
|
jpayne@68
|
1075 requiring additional characters (searches, multi-key sequences, numeric
|
|
jpayne@68
|
1076 arguments, commands requiring an additional specifier character like
|
|
jpayne@68
|
1077 vi-mode change-char, etc.) work without synchronously waiting for
|
|
jpayne@68
|
1078 additional input.
|
|
jpayne@68
|
1079
|
|
jpayne@68
|
1080 r. Lots of changes so readline builds and runs on MinGW.
|
|
jpayne@68
|
1081
|
|
jpayne@68
|
1082 s. Readline no longer tries to modify the terminal settings when running in
|
|
jpayne@68

1084
|
|
jpayne@68
|
1085 t. The Readline display code no longer sets the location of the last invisible
|

jpayne@68
|
1087
|
|
jpayne@68
|
1088 u. The `change-case' command now correctly changes the case of multibyte
|
|
jpayne@68

1090
|
|
jpayne@68
|
1091 v. Changes to the shared library construction scripts to deal with Windows
|
|
jpayne@68

|
|
jpayne@68
|
1094 w. Fixed the redisplay code to avoid core dumps resulting from a poorly-timed
|
|
jpayne@68
|
1095 SIGWINCH.
|
|
jpayne@68
|
1096
|
|
jpayne@68
|
1097 x. Fixed the non-incremental search code in vi mode to dispose of any current
|
|
jpayne@68
|
1098 undo list when copying a line from the history into the current editing
|
|
jpayne@68
|
1099 buffer.
|
|
jpayne@68
|
1100
|
|
jpayne@68
|
1101 y. Fixed a bug that caused reversing the incremental search direction to
|
|
jpayne@68
|
1102 not work correctly.
|
|
jpayne@68
|
1103
|
|
jpayne@68
|
1104 z. Fixed the vi-mode `U' command to only undo up to the first time insert mode
|
|
jpayne@68
|
1105 was entered, as Posix specifies.
|
|
jpayne@68
|
1106
|
|
jpayne@68
|
1107 aa. Fixed a bug in the vi-mode `r' command that left the cursor in the wrong
|
|
jpayne@68
|
1108 place.
|

jpayne@68
|
1109
|
|
jpayne@68
|
1110 bb. Fixed a redisplay bug caused by moving the cursor vertically to a line

jpayne@68
|
1112
|
|
jpayne@68
|
1113 cc. Fixed a bug that could cause the terminal special chars to be bound in the

|
1114 wrong keymap in vi mode.
|
|
jpayne@68
|
1115
|
|
jpayne@68
|
1116 2. New Features in Readline
|
|
jpayne@68
|
1117
|
|
jpayne@68
|
1118 a. The key sequence sent by the keypad `delete' key is now automatically
|
|
jpayne@68
|
1119 bound to delete-char.
|
|
jpayne@68
|
1120
|
|
jpayne@68
|
1121 b. A negative argument to menu-complete now cycles backward through the
|
|
jpayne@68

1122 completion list.
|
|
jpayne@68
|
1123
|
|
jpayne@68
|
1124 c. A new bindable readline variable: bind-tty-special-chars. If non-zero,
|
|
jpayne@68
|
1125 readline will bind the terminal special characters to their readline
|
|
jpayne@68
|
1126 equivalents when it's called (on by default).
|
|
jpayne@68
|
1127
|
|
jpayne@68
|
1128 d. New bindable command: vi-rubout. Saves deleted text for possible
|
|
jpayne@68
|
1129 reinsertion, as with any vi-mode `text modification' command; `X' is bound
|
|
jpayne@68
|
1130 to this in vi command mode.
|
|
jpayne@68
|
1131
|
|
jpayne@68
|
1132 e. If the rl_completion_query_items is set to a value < 0, readline never
|
|
jpayne@68
|
1133 asks the user whether or not to view the possible completions.
|
|
jpayne@68
|
1134
|
|
jpayne@68
|
1135 f. The `C-w' binding in incremental search now understands multibyte
|
|
jpayne@68
|
1136 characters.
|
|
jpayne@68
|
1137
|
|
jpayne@68
|
1138 g. New application-callable auxiliary function, rl_variable_value, returns
|
|
jpayne@68
|
1139 a string corresponding to a readline variable's value.
|
|
jpayne@68
|
1140
|
|
jpayne@68
|
1141 h. When parsing inputrc files and variable binding commands, the parser
|
|
jpayne@68
|
1142 strips trailing whitespace from values assigned to boolean variables
|
|
jpayne@68
|
1143 before checking them.
|
|
jpayne@68
|
1144
|
|
jpayne@68
|
1145 i. A new external application-controllable variable that allows the LINES
|
|
jpayne@68
|
1146 and COLUMNS environment variables to set the window size regardless of
|
|
jpayne@68
|
1147 what the kernel returns.

1150 This document details the changes between this version, readline-5.0,
|
|
jpayne@68
|
1151 and the previous version, readline-4.3.
|
|
jpayne@68
|
1152
|
|
jpayne@68
|
1153 1. Changes to Readline
|
|
jpayne@68
|
1154
|
|
jpayne@68
|
1155 a. Fixes to avoid core dumps because of null pointer references in the
|
|
jpayne@68
|
1156 multibyte character code.
|
|
jpayne@68
|
1157
|
|
jpayne@68
|
1158 b. Fix to avoid infinite recursion caused by certain key combinations.
|
|
jpayne@68
|
1159
|
|
jpayne@68
|
1160 c. Fixed a bug that caused the vi-mode `last command' to be set incorrectly.
|
|
jpayne@68
|
1161
|
|
jpayne@68
|
1162 d. Readline no longer tries to read ahead more than one line of input, even
|
|
jpayne@68

1163 when more is available.
|
|
jpayne@68
|
1164
|
|
jpayne@68
|
1165 e. Fixed the code that adjusts the point to not mishandle null wide
|
|
jpayne@68
|
1166 characters.
|
|
jpayne@68
|
1167
|
|
jpayne@68
|
1168 f. Fixed a bug in the history expansion `g' modifier that caused it to skip
|
|
jpayne@68
|
1169 every other match.
|
|
jpayne@68
|
1170
|
|
jpayne@68
|
1171 g. Fixed a bug that caused the prompt to overwrite previous output when the
|
|
jpayne@68
|
1172 output doesn't contain a newline and the locale supports multibyte
|
|
jpayne@68
|
1173 characters. This same change fixes the problem of readline redisplay
|
|
jpayne@68
|
1174 slowing down dramatically as the line gets longer in multibyte locales.
|
|
jpayne@68
|
1175
|
|
jpayne@68
|
1176 h. History traversal with arrow keys in vi insertion mode causes the cursor
|
|
jpayne@68
|
1177 to be placed at the end of the new line, like in emacs mode.
|
|
jpayne@68
|
1178
|
|
jpayne@68
|
1179 i. The locale initialization code does a better job of using the right
|
|
jpayne@68
|
1180 precedence and defaulting when checking the appropriate environment
|
|
jpayne@68
|
1181 variables.
|
|
jpayne@68
|
1182
|
|
jpayne@68

1185
|
|
jpayne@68
|
1186 k. The overwrite mode code received several bug fixes to improve undo.
|
|
jpayne@68
|
1187
|
|
jpayne@68

|
|
jpayne@68
|
1189
|
|
jpayne@68
|
1190 m. The callback character reading interface should not hang waiting to read
|
|
jpayne@68
|
1191 keyboard input.
|
|
jpayne@68
|
1192
|
|
jpayne@68
|
1193 n. Fixed a bug with redoing vi-mode `s' command.
|
|
jpayne@68
|
1194
|
|
jpayne@68
|
1195 o. The code that initializes the terminal tracks changes made to the terminal
|
|
jpayne@68
|
1196 special characters with stty(1) (or equivalent), so that these changes
|
|
jpayne@68
|
1197 are reflected in the readline bindings. New application-callable function
|
|
jpayne@68
|
1198 to make it work: rl_tty_unset_default_bindings().
|
|
jpayne@68
|
1199
|
|
jpayne@68
|
1200 p. Fixed a bug that could cause garbage to be inserted in the buffer when
|
|
jpayne@68
|
1201 changing character case in vi mode when using a multibyte locale.
|
|
jpayne@68
|
1202
|
|
jpayne@68
|
1203 q. Fixed a bug in the redisplay code that caused problems on systems
|
|
jpayne@68
|
1204 supporting multibyte characters when moving between history lines when the
|
|
jpayne@68
|
1205 new line has more glyphs but fewer bytes.
|
|
jpayne@68
|
1206
|
|
jpayne@68
|
1207 r. Undo and redo now work better after exiting vi insertion mode.
|
|
jpayne@68
|
1208
|
|
jpayne@68
|
1209 s. Make sure system calls are restarted after a SIGWINCH is received using
|
|
jpayne@68
|
1210 SA_RESTART.
|
|
jpayne@68
|
1211
|
|
jpayne@68
|
1212 t. Improvements to the code that displays possible completions when using
|
|
jpayne@68
|
1213 multibyte characters.
|
|
jpayne@68
|
1214
|
|
jpayne@68
|
1215 u. Fixed a problem when parsing nested if statements in inputrc files.
|
|
jpayne@68
|
1216
|
|
jpayne@68
|
1217 v. The completer now takes multibyte characters into account when looking for
|
|
jpayne@68
|
1218 quoted substrings on which to perform completion.
|
|
jpayne@68
|
1219
|
|
jpayne@68
|
1220 w. The history search functions now perform better bounds checking on the
|
|
jpayne@68
|
1221 history list.
|
|
jpayne@68
|
1222
|
|
jpayne@68
|
1223 x. Change to history expansion functions to treat `^' as equivalent to word
|
|
jpayne@68
|
1224 one, as the documentation states.
|
|
jpayne@68
|
1225
|
|
jpayne@68
|
1226 y. Some changes to the display code to improve display and redisplay of

|
|
jpayne@68
|
1230
|
|
jpayne@68

|
|
jpayne@68
|
1232 last character of a word if invoked while point was on the word's
|
|
jpayne@68
|
1233 next-to-last character.
|
|
jpayne@68
|
1234
|
|
jpayne@68
|
1235 bb. Fixed a bug that could cause incorrect filename quoting when
|
|
jpayne@68
|
1236 case-insensitive completion was enabled and the word being completed
|
|
jpayne@68
|
1237 contained backslashes quoting word break characters.
|
|
jpayne@68
|
1238
|
|
jpayne@68
|
1239 cc. Fixed a bug in redisplay triggered when the prompt string contains
|
|
jpayne@68
|
1240 invisible characters.
|
|
jpayne@68
|
1241
|
|
jpayne@68
|
1242 dd. Fixed some display (and other) bugs encountered in multibyte locales

jpayne@68
|
1249
|
|

|
jpayne@68
|
1258
|
|
jpayne@68
|
1259 jj. Fixed a bug in vi-mode that caused multi-digit count arguments to work
|
|
jpayne@68
|
1260 incorrectly.
|
|
jpayne@68
|
1261
|
|
jpayne@68
|
1262 kk. Fixed a problem in vi-mode that caused the last text modification command
|
|
jpayne@68
|
1263 to not be remembered across different command lines.
|
|
jpayne@68
|
1264
|
|
jpayne@68
|
1265 ll. Fixed problems with changing characters and changing case at the end of
|
|
jpayne@68

jpayne@68
|
1275
|
|
jpayne@68

1276 2. New Features in Readline
|
|
jpayne@68
|
1277
|
|
jpayne@68
|
1278 a. History expansion has a new `a' modifier equivalent to the `g' modifier
|
|
jpayne@68
|
1279 for compatibility with the BSD csh.
|
|
jpayne@68
|
1280
|
|
jpayne@68
|
1281 b. History expansion has a new `G' modifier equivalent to the BSD csh `g'
|
|
jpayne@68
|
1282 modifier, which performs a substitution once per word.
|
|
jpayne@68
|
1283
|
|
jpayne@68
|
1284 c. All non-incremental search operations may now undo the operation of

|
|
jpayne@68
|
1289
|
|
jpayne@68
|
1290 e. New bindable variable, `show-all-if-unmodified'. If set, the readline
|
|
jpayne@68
|
1291 completer will list possible completions immediately if there is more
|
|
jpayne@68
|
1292 than one completion and partial completion cannot be performed.
|
|
jpayne@68
|
1293
|
|
jpayne@68
|
1294 f. There is a new application-callable `free_history_entry()' function.
|
|
jpayne@68
|
1295
|
|
jpayne@68
|
1296 g. History list entries now contain timestamp information; the history file
|
|
jpayne@68
|
1297 functions know how to read and write timestamp information associated
|
|
jpayne@68
|
1298 with each entry.
|
|
jpayne@68
|
1299
|
|
jpayne@68
|
1300 h. Four new key binding functions have been added:
|
|
jpayne@68
|
1301
|
|
jpayne@68
|
1302 rl_bind_key_if_unbound()
|
|
jpayne@68
|
1303 rl_bind_key_if_unbound_in_map()
|
|
jpayne@68
|
1304 rl_bind_keyseq_if_unbound()
|
|
jpayne@68
|
1305 rl_bind_keyseq_if_unbound_in_map()
|
|
jpayne@68
|
1306
|
|
jpayne@68
|
1307 i. New application variable, rl_completion_quote_character, set to any
|
|
jpayne@68
|
1308 quote character readline finds before it calls the application completion
|
|
jpayne@68
|
1309 function.
|
|
jpayne@68
|
1310
|
|
jpayne@68
|
1311 j. New application variable, rl_completion_suppress_quote, settable by an
|
|
jpayne@68
|
1312 application completion function. If set to non-zero, readline does not
|
|
jpayne@68
|
1313 attempt to append a closing quote to a completed word.
|
|
jpayne@68
|
1314
|
|
jpayne@68
|
1315 k. New application variable, rl_completion_found_quote, set to a non-zero
|
|
jpayne@68
|
1316 value if readline determines that the word to be completed is quoted.
|
|
jpayne@68
|
1317 Set before readline calls any application completion function.
|
|
jpayne@68
|
1318
|
|
jpayne@68
|
1319 l. New function hook, rl_completion_word_break_hook, called when readline
|
|
jpayne@68
|
1320 needs to break a line into words when completion is attempted. Allows
|
|
jpayne@68
|
1321 the word break characters to vary based on position in the line.
|
|
jpayne@68
|
1322
|
|
jpayne@68
|
1323 m. New bindable command: unix-filename-rubout. Does the same thing as
|
|
jpayne@68
|
1324 unix-word-rubout, but adds `/' to the set of word delimiters.
|
|
jpayne@68
|
1325
|
|
jpayne@68
|
1326 n. When listing completions, directories have a `/' appended if the
|
|
jpayne@68
|
1327 `mark-directories' option has been enabled.
|
|
jpayne@68
|

1330 This document details the changes between this version, readline-4.3,
|
|
jpayne@68
|
1331 and the previous version, readline-4.2a.
|
|
jpayne@68
|
1332
|
|
jpayne@68
|
1333 1. Changes to Readline
|
|
jpayne@68
|
1334
|
|
jpayne@68
|
1335 a. Fixed output of comment-begin character when listing variable values.
|
|
jpayne@68
|
1336
|
|
jpayne@68
|
1337 b. Added some default key bindings for common escape sequences produced by
|
|
jpayne@68
|
1338 HOME and END keys.
|
|
jpayne@68
|
1339
|
|
jpayne@68
|
1340 c. Fixed the mark handling code to be more emacs-compatible.
|
|
jpayne@68
|
1341
|
|
jpayne@68
|
1342 d. A bug was fixed in the code that prints possible completions to keep it
|
|
jpayne@68
|
1343 from printing empty strings in certain circumstances.
|
|
jpayne@68
|
1344
|
|
jpayne@68
|
1345 e. Change the key sequence printing code to print ESC as M\- if ESC is a
|
|
jpayne@68
|
1346 meta-prefix character -- it's easier for users to understand than \e.
|
|
jpayne@68
|
1347
|
|
jpayne@68
|
1348 f. Fixed unstifle_history() to return values that match the documentation.
|
|
jpayne@68
|
1349
|
|
jpayne@68
|
1350 g. Fixed the event loop (rl_event_hook) to handle the case where the input
|
|
jpayne@68
|
1351 file descriptor is invalidated.
|
|
jpayne@68
|
1352
|
|
jpayne@68
|
1353 h. Fixed the prompt display code to work better when the application has a
|
|
jpayne@68
|
1354 custom redisplay function.
|
|
jpayne@68
|
1355
|
|
jpayne@68
|
1356 i. Changes to make reading and writing the history file a little faster, and
|
|
jpayne@68
|
1357 to cope with huge history files without calling abort(3) from xmalloc.
|
|
jpayne@68
|
1358
|
|
jpayne@68
|
1359 j. The vi-mode `S' and `s' commands are now undone correctly.
|
|
jpayne@68
|
1360
|
|
jpayne@68
|
1361 k. Fixed a problem which caused the display to be messed up when the last
|
|
jpayne@68
|
1362 line of a multi-line prompt (possibly containing invisible characters)
|
|
jpayne@68
|
1363 was longer than the screen width.
|
|
jpayne@68
|
1364
|
|
jpayne@68
|
1365 2. New Features in Readline
|
|
jpayne@68
|
1366
|
|
jpayne@68
|
1367 a. Support for key `subsequences': allows, e.g., ESC and ESC-a to both
|
|
jpayne@68
|
1368 be bound to readline functions. Now the arrow keys may be used in vi
|
|
jpayne@68
|
1369 insert mode.
|
|
jpayne@68
|
1370
|
|
jpayne@68
|
1371 b. When listing completions, and the number of lines displayed is more than
|
|
jpayne@68
|
1372 the screen length, readline uses an internal pager to display the results.
|
|
jpayne@68
|
1373 This is controlled by the `page-completions' variable (default on).
|
|
jpayne@68
|
1374
|
|
jpayne@68
|
1375 c. New code to handle editing and displaying multibyte characters.
|
|
jpayne@68
|
1376
|
|
jpayne@68
|
1377 d. The behavior introduced in bash-2.05a of deciding whether or not to
|
|
jpayne@68
|
1378 append a slash to a completed name that is a symlink to a directory has
|
|
jpayne@68
|
1379 been made optional, controlled by the `mark-symlinked-directories'
|
|
jpayne@68
|
1380 variable (default is the 2.05a behavior).
|
|
jpayne@68
|
1381
|
|
jpayne@68
|
1382 e. The `insert-comment' command now acts as a toggle if given a numeric
|
|
jpayne@68
|
1383 argument: if the first characters on the line don't specify a
|
|
jpayne@68
|
1384 comment, insert one; if they do, delete the comment text
|
|
jpayne@68
|
1385
|
|
jpayne@68
|
1386 f. New application-settable completion variable:
|
|
jpayne@68
|
1387 rl_completion_mark_symlink_dirs, allows an application's completion
|
|
jpayne@68
|
1388 function to temporarily override the user's preference for appending
|
|
jpayne@68
|
1389 slashes to names which are symlinks to directories.
|
|
jpayne@68
|
1390
|
|
jpayne@68
|
1391 g. New function available to application completion functions:
|
|
jpayne@68
|
1392 rl_completion_mode, to tell how the completion function was invoked
|
|
jpayne@68
|
1393 and decide which argument to supply to rl_complete_internal (to list
|
|
jpayne@68
|
1394 completions, etc.).
|
|
jpayne@68
|
1395
|
|
jpayne@68
|
1396 h. Readline now has an overwrite mode, toggled by the `overwrite-mode'
|
|
jpayne@68
|
1397 bindable command, which could be bound to `Insert'.
|
|
jpayne@68
|
1398
|
|
jpayne@68
|
1399 i. New application-settable completion variable:
|
|
jpayne@68
|
1400 rl_completion_suppress_append, inhibits appending of
|
|
jpayne@68
|
1401 rl_completion_append_character to completed words.
|
|
jpayne@68
|
1402
|
|
jpayne@68
|
1403 j. New key bindings when reading an incremental search string: ^W yanks
|
|
jpayne@68
|
1404 the currently-matched word out of the current line into the search
|
|
jpayne@68
|
1405 string; ^Y yanks the rest of the current line into the search string,
|
|
jpayne@68
|
1406 DEL or ^H deletes characters from the search string.
|
|
jpayne@68
|
1407
|
|
jpayne@68
|
1408 -------------------------------------------------------------------------------
|
|
jpayne@68
|
1409 This document details the changes between this version, readline-4.2a,
|
|
jpayne@68
|
1410 and the previous version, readline-4.2.
|
|
jpayne@68
|
1411
|
|
jpayne@68
|
1412 1. Changes to Readline
|
|
jpayne@68
|
1413
|
|
jpayne@68
|
1414 a. More `const' and type casting fixes.
|
|
jpayne@68
|
1415
|
|
jpayne@68
|
1416 b. Changed rl_message() to use vsnprintf(3) (if available) to fix buffer
|
|
jpayne@68
|
1417 overflow problems.
|
|
jpayne@68
|
1418
|
|
jpayne@68
|
1419 c. The completion code no longer appends a `/' or ` ' to a match when
|
|
jpayne@68
|
1420 completing a symbolic link that resolves to a directory name, unless
|
|
jpayne@68
|
1421 the match does not add anything to the word being completed. This
|
|
jpayne@68
|
1422 means that a tab will complete the word up to the full name, but not
|
|
jpayne@68
|
1423 add anything, and a subsequent tab will add a slash.
|
|
jpayne@68
|
1424
|
|
jpayne@68
|
1425 d. Fixed a trivial typo that made the vi-mode `dT' command not work.
|
|
jpayne@68
|
1426
|
|
jpayne@68
|
1427 e. Fixed the tty code so that ^S and ^Q can be inserted with rl_quoted_insert.
|
|
jpayne@68
|
1428
|
|
jpayne@68
|
1429 f. Fixed the tty code so that ^V works more than once.
|
|
jpayne@68
|
1430
|
|
jpayne@68
|
1431 g. Changed the use of __P((...)) for function prototypes to PARAMS((...))
|
|
jpayne@68
|
1432 because the use of __P in typedefs conflicted g++ and glibc.
|
|
jpayne@68
|
1433
|
|
jpayne@68
|
1434 h. The completion code now attempts to do a better job of preserving the
|
|
jpayne@68
|
1435 case of the word the user typed if ignoring case in completions.
|
|
jpayne@68
|
1436
|
|
jpayne@68
|
1437 i. Readline defaults to not echoing the input and lets the terminal
|
|
jpayne@68
|
1438 initialization code enable echoing if there is a controlling terminal.
|
|
jpayne@68
|
1439
|
|
jpayne@68
|
1440 j. The key binding code now processes only two hex digits after a `\x'
|
|
jpayne@68
|
1441 escape sequence, and the documentation was changed to note that the
|
|
jpayne@68
|
1442 octal and hex escape sequences result in an eight-bit value rather
|
|
jpayne@68
|
1443 than strict ASCII.
|
|
jpayne@68
|
1444
|
|
jpayne@68
|
1445 k. Fixed a few places where negative array subscripts could have occurred.
|
|
jpayne@68
|
1446
|
|
jpayne@68
|
1447 l. Fixed the vi-mode code to use a better method to determine the bounds of
|
|
jpayne@68
|
1448 the array used to hold the marks, and to avoid out-of-bounds references.
|
|
jpayne@68
|
1449
|
|
jpayne@68
|
1450 m. Fixed the defines in chardefs.h to work better when chars are signed.
|
|
jpayne@68
|
1451
|
|
jpayne@68
|
1452 n. Fixed configure.in to use the new names for bash autoconf macros.
|
|
jpayne@68
|
1453
|
|
jpayne@68
|
1454 o. Readline no longer attempts to define its own versions of some ctype
|
|
jpayne@68
|
1455 macros if they are implemented as functions in libc but not as macros in
|
|
jpayne@68
|
1456 <ctype.h>.
|
|
jpayne@68
|
1457
|
|
jpayne@68
|
1458 p. Fixed a problem where rl_backward could possibly set point to before
|
|
jpayne@68
|
1459 the beginning of the line.
|
|
jpayne@68
|
1460
|
|
jpayne@68
|
1461 q. Fixed Makefile to not put -I/usr/include into CFLAGS, since it can cause
|
|
jpayne@68
|
1462 include file problems.
|
|
jpayne@68
|
1463
|
|
jpayne@68
|
1464 2. New Features in Readline
|
|
jpayne@68
|
1465
|
|
jpayne@68
|
1466 a. Added extern declaration for rl_get_termcap to readline.h, making it a
|
|
jpayne@68
|
1467 public function (it was always there, just not in readline.h).
|
|
jpayne@68
|
1468
|
|
jpayne@68
|
1469 b. New #defines in readline.h: RL_READLINE_VERSION, currently 0x0402,
|
|
jpayne@68
|
1470 RL_VERSION_MAJOR, currently 4, and RL_VERSION_MINOR, currently 2.
|
|
jpayne@68
|
1471
|
|
jpayne@68
|
1472 c. New readline variable: rl_readline_version, mirrors RL_READLINE_VERSION.
|
|
jpayne@68
|
1473
|
|
jpayne@68
|
1474 d. New bindable boolean readline variable: match-hidden-files. Controls
|
|
jpayne@68
|
1475 completion of files beginning with a `.' (on Unix). Enabled by default.
|
|
jpayne@68
|
1476
|
|
jpayne@68
|
1477 e. The history expansion code now allows any character to terminate a
|
|
jpayne@68
|
1478 `:first-' modifier, like csh.
|
|
jpayne@68
|
1479
|
|
jpayne@68
|
1480 f. The incremental search code remembers the last search string and uses
|
|
jpayne@68
|
1481 it if ^R^R is typed without a search string.
|
|
jpayne@68
|
1482
|
|
jpayne@68
|
1483 h. New bindable variable `history-preserve-point'. If set, the history
|
|
jpayne@68
|
1484 code attempts to place the user at the same location on each history
|
|
jpayne@68
|
1485 line retrieved with previous-history or next-history.
|
|
jpayne@68
|
1486
|
|
jpayne@68
|
1487 -------------------------------------------------------------------------------
|
|
jpayne@68
|
1488 This document details the changes between this version, readline-4.2,
|
|
jpayne@68
|
1489 and the previous version, readline-4.1.
|
|
jpayne@68
|
1490
|
|
jpayne@68
|
1491 1. Changes to Readline
|
|
jpayne@68
|
1492
|
|
jpayne@68
|
1493 a. When setting the terminal attributes on systems using `struct termio',
|
|
jpayne@68
|
1494 readline waits for output to drain before changing the attributes.
|
|
jpayne@68
|
1495
|
|
jpayne@68
|
1496 b. A fix was made to the history word tokenization code to avoid attempts to
|
|
jpayne@68
|
1497 dereference a null pointer.
|
|
jpayne@68
|
1498
|
|
jpayne@68
|
1499 c. Readline now defaults rl_terminal_name to $TERM if the calling application
|
|
jpayne@68
|
1500 has left it unset, and tries to initialize with the resultant value.
|
|
jpayne@68
|
1501
|
|
jpayne@68
|
1502 d. Instead of calling (*rl_getc_function)() directly to get input in certain
|
|
jpayne@68
|
1503 places, readline now calls rl_read_key() consistently.
|
|
jpayne@68
|
1504
|
|
jpayne@68
|
1505 e. Fixed a bug in the completion code that allowed a backslash to quote a
|
|
jpayne@68
|
1506 single quote inside a single-quoted string.
|
|
jpayne@68
|
1507
|
|
jpayne@68
|
1508 f. rl_prompt is no longer assigned directly from the argument to readline(),
|
|
jpayne@68
|
1509 but uses memory allocated by readline. This allows constant strings to
|
|
jpayne@68
|
1510 be passed to readline without problems arising when the prompt processing
|
|
jpayne@68
|
1511 code wants to modify the string.
|
|
jpayne@68
|
1512
|
|
jpayne@68
|
1513 g. Fixed a bug that caused non-interactive history searches to return the
|
|
jpayne@68
|
1514 wrong line when performing multiple searches backward for the same string.
|
|
jpayne@68
|
1515
|
|
jpayne@68
|
1516 h. Many variables, function arguments, and function return values are now
|
|
jpayne@68
|
1517 declared `const' where appropriate, to improve behavior when linking with
|
|
jpayne@68
|
1518 C++ code.
|
|
jpayne@68
|
1519
|
|
jpayne@68
|
1520 i. The control character detection code now works better on systems where
|
|
jpayne@68
|
1521 `char' is unsigned by default.
|
|
jpayne@68
|
1522
|
|
jpayne@68
|
1523 j. The vi-mode numeric argument is now capped at 999999, just like emacs mode.
|
|
jpayne@68
|
1524
|
|
jpayne@68
|
1525 k. The Function, CPFunction, CPPFunction, and VFunction typedefs have been
|
|
jpayne@68
|
1526 replaced with a set of specific prototyped typedefs, though they are
|
|
jpayne@68
|
1527 still in the readline header files for backwards compatibility.
|
|
jpayne@68
|
1528
|
|
jpayne@68
|
1529 m. Nearly all of the (undocumented) internal global variables in the library
|
|
jpayne@68
|
1530 now have an _rl_ prefix -- there were a number that did not, like
|
|
jpayne@68
|
1531 screenheight, screenwidth, alphabetic, etc.
|
|
jpayne@68
|
1532
|
|
jpayne@68
|
1533 n. The ding() convenience function has been renamed to rl_ding(), though the
|
|
jpayne@68
|
1534 old function is still defined for backwards compatibility.
|
|
jpayne@68
|
1535
|
|
jpayne@68
|
1536 o. The completion convenience functions filename_completion_function,
|
|
jpayne@68
|
1537 username_completion_function, and completion_matches now have an rl_
|
|
jpayne@68
|
1538 prefix, though the old names are still defined for backwards compatibility.
|
|
jpayne@68
|
1539
|
|
jpayne@68
|
1540 p. The functions shared by readline and bash (linkage is satisfied from bash
|
|
jpayne@68
|
1541 when compiling with bash, and internally otherwise) now have an sh_ prefix.
|
|
jpayne@68
|
1542
|
|
jpayne@68
|
1543 q. Changed the shared library creation procedure on Linux and BSD/OS 4.x so
|
|
jpayne@68
|
1544 that the `soname' contains only the major version number rather than the
|
|
jpayne@68
|
1545 major and minor numbers.
|
|
jpayne@68
|
1546
|
|
jpayne@68
|
1547 r. Fixed a redisplay bug that occurred when the prompt spanned more than one
|
|
jpayne@68
|
1548 physical line and contained invisible characters.
|
|
jpayne@68
|
1549
|
|
jpayne@68
|
1550 s. Added a missing `includedir' variable to the Makefile.
|
|
jpayne@68
|
1551
|
|
jpayne@68
|
1552 t. When installing the shared libraries, make sure symbolic links are relative.
|
|
jpayne@68
|
1553
|
|
jpayne@68
|
1554 u. Added configure test so that it can set `${MAKE}' appropriately.
|
|
jpayne@68
|
1555
|
|
jpayne@68
|
1556 v. Fixed a bug in rl_forward that could cause the point to be set to before
|
|
jpayne@68
|
1557 the beginning of the line in vi mode.
|
|
jpayne@68
|
1558
|
|
jpayne@68
|
1559 w. Fixed a bug in the callback read-char interface to make it work when a
|
|
jpayne@68
|
1560 readline function pushes some input onto the input stream with
|
|
jpayne@68
|
1561 rl_execute_next (like the incremental search functions).
|
|
jpayne@68
|
1562
|
|
jpayne@68
|
1563 x. Fixed a file descriptor leak in the history file manipulation code that
|
|
jpayne@68
|
1564 was tripped when attempting to truncate a non-regular file (like
|
|
jpayne@68
|
1565 /dev/null).
|
|
jpayne@68
|
1566
|
|
jpayne@68
|
1567 y. Changes to make all of the exported readline functions declared in
|
|
jpayne@68
|
1568 readline.h have an rl_ prefix (rltty_set_default_bindings is now
|
|
jpayne@68
|
1569 rl_tty_set_default_bindings, crlf is now rl_crlf, etc.)
|
|
jpayne@68
|
1570
|
|
jpayne@68
|
1571 z. The formatted documentation included in the base readline distribution
|
|
jpayne@68
|
1572 is no longer removed on a `make distclean'.
|
|
jpayne@68
|
1573
|
|
jpayne@68
|
1574 aa. Some changes were made to avoid gcc warnings with -Wall.
|
|
jpayne@68
|
1575
|
|
jpayne@68
|
1576 bb. rl_get_keymap_by_name now finds keymaps case-insensitively, so
|
|
jpayne@68
|
1577 `set keymap EMACS' works.
|
|
jpayne@68
|
1578
|
|
jpayne@68
|
1579 cc. The history file writing and truncation functions now return a useful
|
|
jpayne@68
|
1580 status on error.
|
|
jpayne@68
|
1581
|
|
jpayne@68
|
1582 dd. Fixed a bug that could cause applications to dereference a NULL pointer
|
|
jpayne@68
|
1583 if a NULL second argument was passed to history_expand().
|
|
jpayne@68
|
1584
|
|
jpayne@68
|
1585 ee. If a hook function assigned to rl_event_hook sets rl_done to a non-zero
|
|
jpayne@68
|
1586 value, rl_read_key() now immediately returns '\n' (which is assumed to
|
|
jpayne@68
|
1587 be bound to accept-line).
|
|
jpayne@68
|
1588
|
|
jpayne@68
|
1589 2. New Features in Readline
|
|
jpayne@68
|
1590
|
|
jpayne@68
|
1591 a. The blink timeout for paren matching is now settable by applications,
|
|
jpayne@68
|
1592 via the rl_set_paren_blink_timeout() function.
|
|
jpayne@68
|
1593
|
|
jpayne@68
|
1594 b. _rl_executing_macro has been renamed to rl_executing_macro, which means
|
|
jpayne@68
|
1595 it's now part of the public interface.
|
|
jpayne@68
|
1596
|
|
jpayne@68
|
1597 c. Readline has a new variable, rl_readline_state, which is a bitmap that
|
|
jpayne@68
|
1598 encapsulates the current state of the library; intended for use by
|
|
jpayne@68
|
1599 callbacks and hook functions.
|
|
jpayne@68
|
1600
|
|
jpayne@68
|
1601 d. rlfe has a new -l option to log input and output (-a appends to logfile),
|
|
jpayne@68
|
1602 a new -n option to set the readline application name, and -v and -h
|
|
jpayne@68
|
1603 options for version and help information.
|
|
jpayne@68
|
1604
|
|
jpayne@68
|
1605 e. rlfe can now perform filename completion for the inferior process if the
|
|
jpayne@68
|
1606 OS has a /proc/<PID>/cwd that can be read with readlink(2) to get the
|
|
jpayne@68
|
1607 inferior's current working directory.
|
|
jpayne@68
|
1608
|
|
jpayne@68
|
1609 f. A new file, rltypedefs.h, contains the new typedefs for function pointers
|
|
jpayne@68
|
1610 and is installed by `make install'.
|
|
jpayne@68
|
1611
|
|
jpayne@68
|
1612 g. New application-callable function rl_set_prompt(const char *prompt):
|
|
jpayne@68
|
1613 expands its prompt string argument and sets rl_prompt to the result.
|
|
jpayne@68
|
1614
|
|
jpayne@68
|
1615 h. New application-callable function rl_set_screen_size(int rows, int cols):
|
|
jpayne@68
|
1616 public method for applications to set readline's idea of the screen
|
|
jpayne@68
|
1617 dimensions.
|
|
jpayne@68
|
1618
|
|
jpayne@68
|
1619 i. The history example program (examples/histexamp.c) is now built as one
|
|
jpayne@68
|
1620 of the examples.
|
|
jpayne@68
|
1621
|
|
jpayne@68
|
1622 j. The documentation has been updated to cover nearly all of the public
|
|
jpayne@68
|
1623 functions and variables declared in readline.h.
|
|
jpayne@68
|
1624
|
|
jpayne@68
|
1625 k. New function, rl_get_screen_size (int *rows, int *columns), returns
|
|
jpayne@68
|
1626 readline's idea of the screen dimensions.
|
|
jpayne@68
|
1627
|
|
jpayne@68
|
1628 l. The timeout in rl_gather_tyi (readline keyboard input polling function)
|
|
jpayne@68
|
1629 is now settable via a function (rl_set_keyboard_input_timeout()).
|
|
jpayne@68
|
1630
|
|
jpayne@68
|
1631 m. Renamed the max_input_history variable to history_max_entries; the old
|
|
jpayne@68
|
1632 variable is maintained for backwards compatibility.
|
|
jpayne@68
|
1633
|
|
jpayne@68
|
1634 n. The list of characters that separate words for the history tokenizer is
|
|
jpayne@68
|
1635 now settable with a variable: history_word_delimiters. The default
|
|
jpayne@68
|
1636 value is as before.
|
|
jpayne@68
|
1637
|
|
jpayne@68
|
1638 o. There is a new history.3 manual page documenting the history library.
|
|
jpayne@68

|
1641 This document details the changes between this version, readline-4.1,
|
|
jpayne@68
|
1642 and the previous version, readline-4.0.
|
|
jpayne@68
|
1643
|
|
jpayne@68
|
1644 1. Changes to Readline
|
|
jpayne@68
|
1645
|
|
jpayne@68
|
1646 a. Changed the HTML documents so that the table-of-contents is no longer
|
|
jpayne@68
|
1647 a separate file.
|
|
jpayne@68
|
1648
|
|
jpayne@68
|
1649 b. Changes to the shared object configuration for: Irix 5.x, Irix 6.x,
|
|
jpayne@68
|
1650 OSF/1.
|
|
jpayne@68
|
1651
|
|
jpayne@68
|
1652 c. The shared library major and minor versions are now constructed
|
|
jpayne@68
|
1653 automatically by configure and substituted into the makefiles.
|
|
jpayne@68
|
1654
|
|
jpayne@68
|
1655 d. It's now possible to install the shared libraries separately from the
|
|
jpayne@68
|
1656 static libraries.
|
|
jpayne@68
|
1657
|
|
jpayne@68
|
1658 e. The history library tries to truncate the history file only if it is a
|
|
jpayne@68
|
1659 regular file.
|
|
jpayne@68
|
1660
|
|
jpayne@68
|
1661 f. A bug that caused _rl_dispatch to address negative array indices on
|
|
jpayne@68
|
1662 systems with signed chars was fixed.
|
|
jpayne@68
|
1663
|
|
jpayne@68
|
1664 g. rl-yank-nth-arg now leaves the history position the same as when it was
|
|
jpayne@68
|
1665 called.
|
|
jpayne@68
|
1666
|
|
jpayne@68
|
1667 h. Changes to the completion code to handle MS-DOS drive-letter:pathname
|
|
jpayne@68
|
1668 filenames.
|
|
jpayne@68
|
1669
|
|
jpayne@68
|
1670 i. Completion is now case-insensitive by default on MS-DOS.
|
|
jpayne@68
|
1671
|
|
jpayne@68
|
1672 j. Fixes to the history file manipulation code for MS-DOS.
|
|
jpayne@68
|
1673
|
|
jpayne@68
|
1674 k. Readline attempts to bind the arrow keys to appropriate defaults on MS-DOS.
|
|
jpayne@68
|
1675
|
|
jpayne@68
|
1676 l. Some fixes were made to the redisplay code for better operation on MS-DOS.
|
|
jpayne@68
|
1677
|
|
jpayne@68
|
1678 m. The quoted-insert code will now insert tty special chars like ^C.
|
|
jpayne@68
|
1679
|
|
jpayne@68
|
1680 n. A bug was fixed that caused the display code to reference memory before
|
|
jpayne@68
|
1681 the start of the prompt string.
|
|
jpayne@68
|
1682
|
|
jpayne@68
|
1683 o. More support for __EMX__ (OS/2).
|
|
jpayne@68
|
1684
|
|
jpayne@68
|
1685 p. A bug was fixed in readline's signal handling that could cause infinite
|
|
jpayne@68
|
1686 recursion in signal handlers.
|
|
jpayne@68
|
1687
|
|
jpayne@68
|
1688 q. A bug was fixed that caused the point to be less than zero when rl_forward
|
|
jpayne@68
|
1689 was given a very large numeric argument.
|
|
jpayne@68
|
1690
|
|
jpayne@68
|
1691 r. The vi-mode code now gets characters via the application-settable value
|
|
jpayne@68
|
1692 of rl_getc_function rather than calling rl_getc directly.
|
|
jpayne@68
|
1693
|
|
jpayne@68
|
1694 s. The history file code now uses O_BINARY mode when reading and writing
|
|
jpayne@68
|
1695 the history file on cygwin32.
|
|
jpayne@68
|
1696
|
|
jpayne@68
|
1697 t. Fixed a bug in the redisplay code for lines with more than 256 line
|
|
jpayne@68
|
1698 breaks.
|
|
jpayne@68
|
1699
|
|
jpayne@68
|
1700 u. A bug was fixed which caused invisible character markers to not be
|
|
jpayne@68
|
1701 stripped from the prompt string if the terminal was in no-echo mode.
|
|
jpayne@68
|
1702
|
|
jpayne@68
|
1703 v. Readline no longer tries to get the variables it needs for redisplay
|
|
jpayne@68
|
1704 from the termcap entry if the calling application has specified its
|
|
jpayne@68
|
1705 own redisplay function. Readline treats the terminal as `dumb' in
|
|
jpayne@68
|
1706 this case.
|
|
jpayne@68
|
1707
|
|
jpayne@68
|
1708 w. Fixes to the SIGWINCH code so that a multiple-line prompt with escape
|
|
jpayne@68
|
1709 sequences is redrawn correctly.
|
|
jpayne@68
|
1710
|
|
jpayne@68
|
1711 x. Changes to the install and install-shared targets so that the libraries
|
|
jpayne@68
|
1712 and header files are installed separately.
|
|
jpayne@68
|
1713
|
|
jpayne@68
|
1714 2. New Features in Readline
|
|
jpayne@68
|
1715
|
|
jpayne@68
|
1716 a. A new Readline `user manual' is in doc/rluserman.texinfo.
|
|
jpayne@68
|
1717
|
|
jpayne@68
|
1718 b. Parentheses matching is now always compiled into readline, and enabled
|
|
jpayne@68
|
1719 or disabled when the value of the `blink-matching-paren' variable is
|
|
jpayne@68
|
1720 changed.
|
|
jpayne@68
|
1721
|
|
jpayne@68
|
1722 c. MS-DOS systems now use ~/_inputrc as the last-ditch inputrc filename.
|
|
jpayne@68
|
1723
|
|
jpayne@68
|
1724 d. MS-DOS systems now use ~/_history as the default history file.
|
|
jpayne@68
|
1725
|
|
jpayne@68
|
1726 e. history-search-{forward,backward} now leave the point at the end of the
|
|
jpayne@68
|
1727 line when the string to search for is empty, like
|
|
jpayne@68
|
1728 {reverse,forward}-search-history.
|
|
jpayne@68
|
1729
|
|
jpayne@68
|
1730 f. history-search-{forward,backward} now leave the last history line found
|
|
jpayne@68
|
1731 in the readline buffer if the second or subsequent search fails.
|
|
jpayne@68
|
1732
|
|
jpayne@68
|
1733 g. New function for use by applications: rl_on_new_line_with_prompt, used
|
|
jpayne@68
|
1734 when an application displays the prompt itself before calling readline().
|
|
jpayne@68
|
1735
|
|
jpayne@68
|
1736 h. New variable for use by applications: rl_already_prompted. An application
|
|
jpayne@68
|
1737 that displays the prompt itself before calling readline() must set this to
|
|
jpayne@68
|
1738 a non-zero value.
|
|
jpayne@68
|
1739
|
|
jpayne@68
|
1740 i. A new variable, rl_gnu_readline_p, always 1. The intent is that an
|
|
jpayne@68
|
1741 application can verify whether or not it is linked with the `real'
|
|
jpayne@68
|
1742 readline library or some substitute.
|
|
jpayne@68
|
1743
|
|
jpayne@68
|
1744 j. Per Bothner's `rlfe' (pronounced `Ralphie') readline front-end program
|
|
jpayne@68
|
1745 is included in the examples subdirectory, though it is not built
|
|
jpayne@68
|
1746 by default.
|
|
jpayne@68
|
1747
|
|
jpayne@68
|
1748 -------------------------------------------------------------------------------

|
jpayne@68
|
1749 This document details the changes between this version, readline-4.0,
|
|
jpayne@68
|
1750 and the previous version, readline-2.2.
|
|
jpayne@68
|
1751
|
|
jpayne@68
|
1752 1. Changes to Readline
|
|
jpayne@68
|
1753
|
|
jpayne@68
|
1754 a. The version number is now 4.0, to match the major and minor version
|
|
jpayne@68
|
1755 numbers on the shared readline and history libraries. Future
|
|
jpayne@68
|
1756 releases will maintain the identical numbering.
|
|
jpayne@68
|
1757
|
|
jpayne@68
|
1758 b. Fixed a typo in the `make install' recipe that copied libreadline.a
|
|
jpayne@68
|
1759 to libhistory.old right after installing it.
|
|
jpayne@68
|
1760
|
|
jpayne@68
|
1761 c. The readline and history info files are now installed out of the source
|
|
jpayne@68
|
1762 directory if they are not found in the build directory.
|
|
jpayne@68
|
1763
|
|
jpayne@68
|
1764 d. The library no longer exports a function named `savestring' -- backwards
|
|
jpayne@68
|
1765 compatibility be damned.
|
|
jpayne@68
|
1766
|
|
jpayne@68
|
1767 e. There is no longer any #ifdef SHELL code in the source files.
|
|
jpayne@68
|
1768
|
|
jpayne@68
|
1769 f. Some changes were made to the key binding code to fix memory leaks and
|
|
jpayne@68
|
1770 better support Win32 systems.
|
|
jpayne@68
|
1771
|
|
jpayne@68
|
1772 g. Fixed a silly typo in the paren matching code -- it's microseconds, not
|
|
jpayne@68
|
1773 milliseconds.
|
|
jpayne@68
|
1774
|
|
jpayne@68
|
1775 h. The readline library should be compilable by C++ compilers.
|
|
jpayne@68
|
1776
|
|
jpayne@68
|
1777 i. The readline.h public header file now includes function prototypes for
|
|
jpayne@68
|
1778 all readline functions, and some changes were made to fix errors in the
|
|
jpayne@68
|
1779 source files uncovered by the use of prototypes.
|
|
jpayne@68
|
1780
|
|
jpayne@68
|
1781 j. The maximum numeric argument is now clamped at 1000000.
|
|
jpayne@68
|
1782
|
|
jpayne@68
|
1783 k. Fixes to rl_yank_last_arg to make it behave better.
|
|
jpayne@68
|
1784
|
|
jpayne@68
|
1785 l. Fixed a bug in the display code that caused core dumps if the prompt
|
|
jpayne@68
|
1786 string length exceeded 1024 characters.
|
|
jpayne@68
|
1787
|
|
jpayne@68
|
1788 m. The menu completion code was fixed to properly insert a single completion
|
|
jpayne@68
|
1789 if there is only one match.
|
|
jpayne@68
|
1790
|
|
jpayne@68
|
1791 n. A bug was fixed that caused the display code to improperly display tabs
|
|
jpayne@68
|
1792 after newlines.
|
|
jpayne@68
|
1793
|
|
jpayne@68
|
1794 o. A fix was made to the completion code in which a typo caused the wrong
|
|
jpayne@68
|
1795 value to be passed to the function that computed the longest common
|
|
jpayne@68
|
1796 prefix of the list of matches.
|
|
jpayne@68
|
1797
|
|
jpayne@68
|
1798 p. The completion code now checks the value of rl_filename_completion_desired,
|
|
jpayne@68
|
1799 which is set by application-supplied completion functions to indicate
|
|
jpayne@68
|
1800 that filename completion is being performed, to decide whether or not to
|
|
jpayne@68
|
1801 call an application-supplied `ignore completions' function.
|
|
jpayne@68
|
1802
|
|
jpayne@68
|
1803 q. Code was added to the history library to catch history substitutions
|
|
jpayne@68
|
1804 using `&' without a previous history substitution or search having been
|
|
jpayne@68
|
1805 performed.
|
|
jpayne@68
|
1806
|
|
jpayne@68
|
1807

|
jpayne@68
|
1808 2. New Features in Readline
|
|
jpayne@68
|
1809
|
|
jpayne@68
|
1810 a. There is a new script, support/shobj-conf, to do system-specific shared
|
|
jpayne@68
|
1811 object and library configuration. It generates variables for configure
|
|
jpayne@68
|
1812 to substitute into makefiles. The README file provides a detailed
|
|
jpayne@68
|
1813 explanation of the shared library creation process.
|
|
jpayne@68
|
1814
|
|
jpayne@68
|
1815 b. Shared libraries and objects are now built in the `shlib' subdirectory.
|
|
jpayne@68
|
1816 There is a shlib/Makefile.in to control the build process. `make shared'
|
|
jpayne@68
|
1817 from the top-level directory is still the right way to build shared
|
|
jpayne@68
|
1818 versions of the libraries.
|
|
jpayne@68
|
1819
|
|
jpayne@68
|
1820 c. rlconf.h is now installed, so applications can find out which features
|
|
jpayne@68
|
1821 have been compiled into the installed readline and history libraries.
|
|
jpayne@68
|
1822
|
|
jpayne@68
|
1823 d. rlstdc.h is now an installed header file.
|
|
jpayne@68
|
1824
|
|
jpayne@68
|
1825 e. Many changes to the signal handling:
|
|
jpayne@68
|
1826 o Readline now catches SIGQUIT and cleans up the tty before returning;
|
|
jpayne@68
|
1827 o A new variable, rl_catch_signals, is available to application writers
|
|
jpayne@68
|
1828 to indicate to readline whether or not it should install its own
|
|
jpayne@68
|
1829 signal handlers for SIGINT, SIGTERM, SIGQUIT, SIGALRM, SIGTSTP,
|
|
jpayne@68
|
1830 SIGTTIN, and SIGTTOU;
|
|
jpayne@68
|
1831 o A new variable, rl_catch_sigwinch, is available to application
|
|
jpayne@68
|
1832 writers to indicate to readline whether or not it should install its
|
|
jpayne@68
|
1833 own signal handler for SIGWINCH, which will chain to the calling
|
|
jpayne@68
|
1834 applications's SIGWINCH handler, if one is installed;
|
|
jpayne@68
|
1835 o There is a new function, rl_free_line_state, for application signal
|
|
jpayne@68
|
1836 handlers to call to free up the state associated with the current
|
|
jpayne@68
|
1837 line after receiving a signal;
|
|
jpayne@68
|
1838 o There is a new function, rl_cleanup_after_signal, to clean up the
|
|
jpayne@68
|
1839 display and terminal state after receiving a signal;
|
|
jpayne@68
|
1840 o There is a new function, rl_reset_after_signal, to reinitialize the
|
|
jpayne@68
|
1841 terminal and display state after an application signal handler
|
|
jpayne@68
|
1842 returns and readline continues
|
|
jpayne@68
|
1843
|
|
jpayne@68
|
1844 f. There is a new function, rl_resize_terminal, to reset readline's idea of
|
|
jpayne@68
|
1845 the screen size after a SIGWINCH.
|
|
jpayne@68
|
1846
|
|
jpayne@68
|
1847 g. New public functions: rl_save_prompt and rl_restore_prompt. These were
|
|
jpayne@68
|
1848 previously private functions with a `_' prefix. These functions are
|
|
jpayne@68
|
1849 used when an application wants to write a message to the `message area'
|
|
jpayne@68
|
1850 with rl_message and have the prompt restored correctly when the message
|
|
jpayne@68
|
1851 is erased.
|
|
jpayne@68
|
1852
|
|
jpayne@68
|
1853 h. New function hook: rl_pre_input_hook, called just before readline starts
|
|
jpayne@68
|
1854 reading input, after initialization.
|
|
jpayne@68
|
1855
|
|
jpayne@68
|
1856 i. New function hook: rl_display_matches_hook, called when readline would
|
|
jpayne@68
|
1857 display the list of completion matches. The new function
|
|
jpayne@68
|
1858 rl_display_match_list is what readline uses internally, and is available
|
|
jpayne@68
|
1859 for use by application functions called via this hook.
|
|
jpayne@68
|
1860
|
|
jpayne@68
|
1861 j. New bindable function, delete-char-or-list, like tcsh.
|
|
jpayne@68
|
1862
|
|
jpayne@68
|
1863 k. A new variable, rl_erase_empty_line, which, if set by an application using
|
|
jpayne@68
|
1864 readline, will cause readline to erase, prompt and all, lines on which the
|
|
jpayne@68
|
1865 only thing typed was a newline.
|
|
jpayne@68
|
1866
|
|
jpayne@68
|
1867 l. There is a new script, support/shlib-install, to install and uninstall
|
|
jpayne@68
|
1868 the shared readline and history libraries.
|
|
jpayne@68
|
1869
|
|
jpayne@68
|
1870 m. A new bindable variable, `isearch-terminators', which is a string
|
|
jpayne@68
|
1871 containing the set of characters that should terminate an incremental
|
|
jpayne@68
|
1872 search without being executed as a command.
|
|
jpayne@68
|
1873
|
|
jpayne@68
|
1874 n. A new bindable function, forward-backward-delete-char.
|
|
jpayne@68

1877 This document details the changes between this version, readline-2.2,
|
|
jpayne@68
|
1878 and the previous version, readline-2.1.
|
|
jpayne@68
|
1879
|
|
jpayne@68
|
1880 1. Changes to Readline
|
|
jpayne@68
|
1881
|
|
jpayne@68
|
1882 a. Added a missing `extern' to a declaration in readline.h that kept
|
|
jpayne@68
|
1883 readline from compiling cleanly on some systems.
|
|
jpayne@68
|
1884
|
|
jpayne@68
|
1885 b. The history file is now opened with mode 0600 when it is written for
|
|
jpayne@68
|
1886 better security.
|
|
jpayne@68
|
1887
|
|
jpayne@68
|
1888 c. Changes were made to the SIGWINCH handling code so that prompt redisplay
|
|
jpayne@68
|
1889 is done better.
|
|
jpayne@68
|
1890
|
|
jpayne@68
|
1891 d. ^G now interrupts incremental searches correctly.
|
|
jpayne@68
|
1892
|
|
jpayne@68
|
1893 e. A bug that caused a core dump when the set of characters to be quoted
|
|
jpayne@68
|
1894 when completing words was empty was fixed.
|
|
jpayne@68
|
1895
|
|
jpayne@68
|
1896 f. Fixed a problem in the readline test program rltest.c that caused a core
|
|
jpayne@68
|
1897 dump.
|
|
jpayne@68
|
1898
|
|
jpayne@68
|
1899 g. The code that handles parser directives in inputrc files now displays
|
|
jpayne@68
|
1900 more error messages.
|
|
jpayne@68
|
1901
|
|
jpayne@68
|
1902 h. The history expansion code was fixed so that the appearance of the
|
|
jpayne@68
|
1903 history comment character at the beginning of a word inhibits history
|
|
jpayne@68
|
1904 expansion for that word and the rest of the input line.
|
|
jpayne@68
|
1905
|
|
jpayne@68
|
1906 i. The code that prints completion listings now behaves better if one or
|
|
jpayne@68
|
1907 more of the filenames contains non-printable characters.
|
|
jpayne@68
|
1908
|
|
jpayne@68
|
1909 j. The time delay when showing matching parentheses is now 0.5 seconds.
|
|
jpayne@68
|
1910
|
|
jpayne@68
|
1911
|
|
jpayne@68
|
1912 2. New Features in Readline
|
|
jpayne@68
|
1913
|
|
jpayne@68
|
1914 a. There is now an option for `iterative' yank-last-arg handline, so a user
|
|
jpayne@68
|
1915 can keep entering `M-.', yanking the last argument of successive history
|
|
jpayne@68
|
1916 lines.
|
|
jpayne@68
|
1917
|
|
jpayne@68
|
1918 b. New variable, `print-completions-horizontally', which causes completion
|
|
jpayne@68
|
1919 matches to be displayed across the screen (like `ls -x') rather than up
|
|
jpayne@68
|
1920 and down the screen (like `ls').
|
|
jpayne@68
|
1921
|
|
jpayne@68
|
1922 c. New variable, `completion-ignore-case', which causes filename completion
|
|
jpayne@68
|
1923 and matching to be performed case-insensitively.
|
|
jpayne@68
|
1924
|
|
jpayne@68
|
1925 d. There is a new bindable command, `magic-space', which causes history
|
|
jpayne@68
|
1926 expansion to be performed on the current readline buffer and a space to
|
|
jpayne@68
|
1927 be inserted into the result.
|
|
jpayne@68
|
1928
|
|
jpayne@68
|
1929 e. There is a new bindable command, `menu-complete', which enables tcsh-like
|
|
jpayne@68
|
1930 menu completion (successive executions of menu-complete insert a single
|
|
jpayne@68
|
1931 completion match, cycling through the list of possible completions).
|
|
jpayne@68
|
1932
|
|
jpayne@68
|
1933 f. There is a new bindable command, `paste-from-clipboard', for use on Win32
|
|
jpayne@68
|
1934 systems, to insert the text from the Win32 clipboard into the editing
|
|
jpayne@68
|
1935 buffer.
|
|
jpayne@68
|
1936
|
|
jpayne@68
|
1937 g. The key sequence translation code now understands printf-style backslash
|
|
jpayne@68
|
1938 escape sequences, including \NNN octal escapes. These escape sequences
|
|
jpayne@68
|
1939 may be used in key sequence definitions or macro values.
|
|
jpayne@68
|
1940
|
|
jpayne@68
|
1941 h. An `$include' inputrc file parser directive has been added.
|
