+.SH NAME
+\fBeditline\fP
+\- line editing user interface
+.SH DESCRIPTION
+When a program using the
+\fBeditline\fP(3)
+library prompts for an input string using the function
+\fBel_wgets\fP(3),
+it reads characters from the terminal.
+Invalid input bytes that do not form characters are silently
+discarded.
+For each character read, one editor command is executed.
+The mapping of input characters to editor commands depends on the
+editing mode.
+There are three editing modes: vi insert mode, vi command mode,
+and emacs mode.
+The default is vi insert mode.
+The program can switch the default to emacs mode by using the
+\fBel_set\fP(3)
+or
+\fBel_parse\fP(3)
+functions, and the user can switch to emacs mode either in the
+\fBeditrc\fP(5)
+configuration file or interactively with the
+\fBed-command\fP
+editor command, in all three cases executing the
+\fBbind Fl e\fP
+builtin command.
+
+If trying to read from the terminal results in end of file or an
+error, the library signals end of file to the program and does not
+return a string.
+.SS Input character bindings
+All default bindings described below can be overridden by individual
+programs and can be changed with the
+\fBeditrc\fP(5)
+\fBbind\fP
+builtin command.
+
+In the following tables,
+`Ctrl-'
+indicates a character with the bit 0x40 flipped, and
+`Meta-'
+indicates a character with the bit 0x80 set.
+In vi insert mode and in emacs mode, all Meta-characters considered
+printable by the current
+\fBlocale\fP(1)
+are bound to
+\fBed-insert\fP
+instead of to the editor command listed below.
+Consequently, in UTF-8 mode, most of the Meta-characters are not
+directly accessible because their code points are occupied by
+printable Unicode characters, and Meta-characters are usually input
+using the
+\fBem-meta-next\fP
+editor command.
+For example, to enter
+`Meta-B'
+in order to call the
+\fBed-prev-word\fP
+editor command in emacs mode, call
+\fBem-meta-next\fP
+by pressing and releasing the escape key (or equivalently, Ctrl-[),
+then press and release the
+`B'
+key.
+If you have configured a Meta-key on your keyboard, for example
+with
+`setxkbmap' -option altwin:left_meta_win ,
+the Ctrl-Meta-characters are directly accessible.
+For example, to enter
+`Ctrl-Meta-H'
+in order to call the
+\fBed-delete-prev-word\fP
+editor command in emacs mode, hold down the keys
+`Ctrl',
+`Meta',
+and
+`H'
+at the same time.
+Alternatively, press and release the escape key, then press and
+release
+`Ctrl-H'.
+
+In vi input mode, input characters are bound to the following editor
+commands by default:
+It Ctrl-D, EOF Ta \fBvi-list-or-eof\fP
+It Ctrl-H, BS Ta \fBvi-delete-prev-char\fP

+
+The remaining
+\fBascii\fP(7)
+characters in the range 0x20 to 0x7e are bound to
+\fBed-insert\fP.
+
+If standard output is not connected to a terminal device
+or
+\fBel_set\fP(3)
+was used to set
+EL_EDITMODE
+to 0, all input character bindings are disabled and all characters
+typed are appended to the edit buffer.
+In that case, the edit buffer is returned to the program after a
+newline or carriage return character is typed, or after the first
+character typed if
+\fBel_set\fP(3)
+was used to set
+EL_UNBUFFERED
+to non-zero.
+.SS Editor commands
+Most editor commands accept an optional argument.
+The argument is entered by prefixing the editor command with one
+or more of the editor commands
+\fBed-argument-digit\fP,
+\fBed-digit\fP,
+\fBem-universal-argument\fP,
+or
+\fBvi-zero\fP.
+When an argument is not provided, it defaults to 1.
+For most editor commands, the effect of an argument is to repeatedly
+execute the command that number of times.
+
+When talking about a character string from a left character to a
+right character, the left character is included in the string, while
+the right character is not included.
+
+If an editor command causes an error, the input character is discarded,
+no action occurs, and the terminal bell is rung.
+In case of a non-fatal error, the terminal bell is also rung,
+but the editor command takes effect anyway.
+
+In the following list, the default key bindings are listed after
+each editor command.
+.TP
+\fBed-argument-digit Pq vi command: 1 to 9; emacs: Meta-0 to Meta-9\fP
+If in argument input mode, append the input digit to the argument
+being read.

+as the most significant digit of the argument.
+It is an error if the input character is not a digit or if the
+existing argument is already greater than a million.
+.TP

+builtin command.
+If in vi command mode, also switch back to vi insert mode.
+Ignore any argument.
+.TP
+\fBed-delete-next-char Pq vi command: x\fP
+Delete the character at the cursor position.
+With an argument, delete that number of characters.
+In emacs mode, it is an error if the cursor is at the end of the
+edit buffer.
+In vi mode, the last character in the edit buffer is deleted in
+that case, and it is an error if the buffer is empty.
+.TP
+\fBed-delete-prev-char Pq vi command: X, Ctrl-H, BS, Ctrl-?, DEL\fP

+string from that position to the cursor, and save it to the cut
+buffer.
+With an argument, delete that number of words.
+It is an error if the cursor is at the beginning of the edit buffer.
+.TP
+\fBed-digit Pq emacs: 0 to 9\fP
+If in argument input mode, append the input digit to the argument
+being read.
+Otherwise, call
+\fBed-insert\fP.

+In insert mode, insert the input character left of the cursor
+position.
+In replace mode, overwrite the character at the cursor and move the
+cursor to the right by one character position.
+Accept an argument to do this repeatedly.
+It is an error if the input character is the NUL character (Ctrl-@).
+Failure to enlarge the edit buffer also results in an error.
+.TP
+\fBed-kill-line Pq vi command: D, Ctrl-K; emacs: Ctrl-K, Ctrl-U\fP

+.SS Macros
+If an input character is bound to the editor command
+\fBed-sequence-lead-in\fP,
+\fBeditline\fP
+attempts to call a macro.
+If the input character by itself forms the name of a macro, that
+macro is executed.
+Otherwise, additional input characters are read until the string
+read forms the name of a macro, in which case that macro is executed,
+or until the string read matches the beginning of none of the existing
+macro names, in which case the string including the final, mismatching
+character is discarded and the terminal bell is rung.
+
+There are two kinds of macros.
+Command macros execute a single editor command.
+Keyboard macros return a string of characters that is appended
+as a new line to the
+.B Input Queue .
+
+The following command macros are defined by default in vi command
+mode and in emacs mode:
+It Esc \&[ A, Esc O A Ta \fBed-prev-history\fP
+It Esc \&[ B, Esc O B Ta \fBed-next-history\fP
+It Esc \&[ C, Esc O C Ta \fBed-next-char\fP
+It Esc \&[ D, Esc O D Ta \fBed-prev-char\fP
+It Esc \&[ F, Esc O F Ta \fBed-move-to-end\fP
+It Esc \&[ H, Esc O H Ta \fBed-move-to-beg\fP
+
+In vi command mode, they are also defined by default without the
+initial escape character.
+
+In addition, the
+\fBeditline\fP
+library tries to bind the strings generated by the arrow keys
+as reported by the
+\fBterminfo\fP(5)
+database to these editor commands, unless that would clobber
+user settings.
+
+In emacs mode, the two-character string
+``Ctrl-X Ctrl-X''
+is bound to the
+\fBem-exchange-mark\fP
+editor command.
+.SS Input Queue
+The
+\fBeditline\fP
+library maintains an input queue operated in FIFO mode.
+Whenever it needs an input character, it takes the first character
+from the first line of the input queue.
+When the queue is empty, it reads from the terminal.
+
+A line can be appended to the end of the input queue in several ways:
+It
+By calling one of the keyboard
+.B Macros .
+It
+By calling the editor command
+\fBvi-redo\fP.
+It
+By calling the editor command
+\fBvi-alias\fP.
+It
+By pressing a key in emacs incremental search mode that doesn't
+have a special meaning in that mode but returns to normal emacs
+mode.
+It
+If an application program directly calls the functions
+\fBel_push\fP(3)
+or
+\fBel_wpush\fP(3),
+it can provide additional, program-specific ways
+of appending to the input queue.
