31 .Os
32 .Sh NAME
33 .Nm editrc
34 .Nd configuration file for editline library
35 .Sh SYNOPSIS
36 .Nm
37 .Sh DESCRIPTION
38 The
39 .Nm
40 file defines various settings to be used by the
41 .Xr editline 3
42 library.
43 .Pp
44 The format of each line is:
45 .Dl [prog:]command [arg [...]]
46 .Pp
47 .Ar command
48 is one of the
49 .Xr editline 3
50 builtin commands.
51 Refer to
52 .Sx BUILTIN COMMANDS
53 for more information.
54 .Pp
55 .Ar prog
56 is the program name string that a program defines when it calls
57 .Xr el_init 3
58 to set up
59 .Xr editline 3 ,
60 which is usually
61 .Va argv[0] .
62 .Ar command
63 will be executed for any program which matches
64 .Ar prog .
65 .Pp
66 .Ar prog
67 may also be a
68 .Xr regex 3
69 style
70 regular expression, in which case
71 .Ar command
72 will be executed for any program that matches the regular expression.
73 .Pp
74 If
75 .Ar prog
76 is absent,
77 .Ar command
78 is executed for all programs.
79 .Sh BUILTIN COMMANDS
80 The
81 .Nm editline
82 library has some builtin commands, which affect the way
83 that the line editing and history functions operate.
84 These are based on similar named builtins present in the
85 .Xr tcsh 1
86 shell.
87 .Pp
88 The following builtin commands are available:
89 .Bl -tag -width 4n
90 .It Ic bind Oo Fl a Oc Oo Fl e Oc Oo Fl k Oc Oo Fl l Oc Oo Fl r Oc \
91 Oo Fl s Oc Oo Fl v Oc Oo Ar key Oo Ar command Oc Oc
92 Without options, list all bound keys, and the editor command to which
93 each is bound.
94 If
95 .Ar key
96 is supplied, show the bindings for
97 .Ar key .
98 If
99 .Ar key command
100 is supplied, bind
101 .Ar command
102 to
103 .Ar key .
104 Options include:
105 .Bl -tag -width 4n
106 .It Fl e
107 Bind all keys to the standard GNU Emacs-like bindings.
108 .It Fl v
109 Bind all keys to the standard
110 .Xr vi 1 Ns -like
111 bindings.
112 .It Fl a
113 List or change key bindings in the
114 .Xr vi 1
115 mode alternate (command mode) key map.
116 .It Fl k
117 .Ar key
118 is interpreted as a symbolic arrow key name, which may be one of
119 .Sq up ,
120 .Sq down ,
121 .Sq left
122 or
123 .Sq right .
124 .It Fl l
125 List all editor commands and a short description of each.
126 .It Fl r
127 Remove a key's binding.
128 .It Fl s
129 .Ar command
130 is taken as a literal string and treated as terminal input when
131 .Ar key
132 is typed.
133 Bound keys in
134 .Ar command
135 are themselves reinterpreted, and this continues for ten levels of
136 interpretation.
137 .El
138 .Pp
139 .Ar command
140 may be one of the commands documented in
141 .Sx "EDITOR COMMANDS"
142 below, or another key.
143 .Pp
144 .Ar key
145 and
146 .Ar command
147 can contain control characters of the form
148 .Sm off
149 .Sq No ^ Ar character
150 .Sm on
151 .Po
152 e.g.
153 .Sq ^A
154 .Pc ,
155 and the following backslashed escape sequences:
156 .Pp
157 .Bl -tag -compact -offset indent -width 4n

171 Horizontal tab
172 .It Ic \ev
173 Vertical tab
174 .Sm off
175 .It Sy \e Ar nnn
176 .Sm on
177 The ASCII character corresponding to the octal number
178 .Ar nnn .
179 .El
180 .Pp
181 .Sq \e
182 nullifies the special meaning of the following character,
183 if it has any, notably
184 .Sq \e
185 and
186 .Sq ^ .
187 .It Ic echotc Oo Fl sv Oc Ar arg Ar ...
188 Exercise terminal capabilities given in
189 .Ar arg Ar ... .
190 If
191 .Ar arg
192 is
193 .Sq baud ,
194 .Sq cols ,
195 .Sq lines ,
196 .Sq rows ,
197 .Sq meta ,
198 or
199 .Sq tabs ,
200 the value of that capability is printed, with
201 .Dq yes
202 or
203 .Dq no
204 indicating that the terminal does or does not have that capability.
205 .Pp
206 .Fl s
207 returns an empty string for non-existent capabilities, rather than
208 causing an error.
209 .Fl v
210 causes messages to be verbose.
211 .It Ic edit Op Li on | Li off
212 Enable or disable the
213 .Nm editline
214 functionality in a program.
215 .It Ic history Ar list | Ar size Dv n | Ar unique Dv n
216 The
217 .Ar list
218 command lists all entries in the history.
219 The
220 .Ar size
221 command sets the history size to
222 .Dv n
223 entries.
224 The
225 .Ar unique
226 command controls if history should keep duplicate entries.
227 If
228 .Dv n
229 is non zero, only keep unique history entries.
230 If
231 .Dv n
232 is zero, then keep all entries (the default).
233 .It Ic telltc
234 List the values of all the terminal capabilities (see
235 .Xr termcap 5 ) .
236 .It Ic settc Ar cap Ar val
237 Set the terminal capability
238 .Ar cap
239 to
240 .Ar val ,
241 as defined in
242 .Xr termcap 5 .
243 No sanity checking is done.
244 .It Ic setty Oo Fl a Oc Oo Fl d Oc Oo Fl q Oc Oo Fl x Oc Oo Ar +mode Oc \
245 Oo Ar -mode Oc Oo Ar mode Oc Oo Ar char=c Oc
246 Control which tty modes that
247 .Nm
248 won't allow the user to change.
249 .Fl d ,
250 .Fl q
251 or
252 .Fl x
253 tells
254 .Ic setty
255 to act on the
256 .Sq edit ,
257 .Sq quote
258 or
259 .Sq execute
260 set of tty modes respectively; defaulting to
261 .Fl x .
262 .Pp
263 Without other arguments,
264 .Ic setty
265 lists the modes in the chosen set which are fixed on
266 .Po
267 .Sq +mode
268 .Pc
269 or off
270 .Po
271 .Sq -mode
272 .Pc .
273 .Fl a
274 lists all tty modes in the chosen set regardless of the setting.
275 With
276 .Ar +mode ,
277 .Ar -mode
278 or
279 .Ar mode ,
280 fixes
281 .Ar mode
282 on or off or removes control of
283 .Ar mode
284 in the chosen set.
285 .Pp
286 .Ic Setty
287 can also be used to set tty characters to particular values using
288 .Ar char=value .
289 If
290 .Ar value
291 is empty
292 then the character is set to
293 .Dv _POSIX_VDISABLE .
