21 |
|
|
|
22 |
root |
1.144 |
Every time a terminal object gets created, extension scripts specified via |
23 |
root |
1.44 |
the C<perl> resource are loaded and associated with it. |
24 |
root |
1.10 |
|
25 |
|
|
Scripts are compiled in a 'use strict' and 'use utf8' environment, and |
26 |
|
|
thus must be encoded as UTF-8. |
27 |
root |
1.6 |
|
28 |
|
|
Each script will only ever be loaded once, even in @@RXVT_NAME@@d, where |
29 |
root |
1.16 |
scripts will be shared (but not enabled) for all terminals. |

You can disable the embedded perl interpreter by setting both "perl-ext" |

This section describes the extensions delivered with this release. You can |
37 |
root |
1.15 |
find them in F<@@RXVT_LIBDIR@@/urxvt/perl/>. |
38 |
|
|
|
39 |
|

You can activate them like this: |

(More) intelligent selection. This extension tries to be more intelligent |
52 |
root |
1.87 |
when the user extends selections (double-click and further clicks). Right |
53 |
|
|
now, it tries to select words, urls and complete shell-quoted |
54 |
|
|
arguments, which is very convenient, too, if your F<ls> supports |
55 |
|
|
C<--quoting-style=shell>. |
56 |
|
|
|
57 |
|
|
A double-click usually selects the word under the cursor, further clicks |
58 |
|
|
will enlarge the selection. |
59 |
root |
1.22 |
|
60 |
root |
1.88 |
The selection works by trying to match a number of regexes and displaying |
61 |
|
|
them in increasing order of length. You can add your own regexes by |
62 |
|
|
specifying resources of the form: |
63 |
|
|
|
64 |
|
|
URxvt.selection.pattern-0: perl-regex |
65 |
|
|
URxvt.selection.pattern-1: perl-regex |
66 |
|
|
... |
67 |
|
|
|
68 |
|
|
The index number (0, 1...) must not have any holes, and each regex must |
69 |
|
|
contain at least one pair of capturing parentheses, which will be used for |
70 |
root |
1.144 |
the match. For example, the following adds a regex that matches everything |
71 |
root |
1.88 |
between two vertical bars: |
72 |
|
|
|
73 |
|
|
URxvt.selection.pattern-0: \\|([^|]+)\\| |
74 |
|
|
|
75 |
root |
1.126 |
Another example: Programs I use often output "absolute path: " at the |
76 |
|
|
beginning of a line when they process multiple files. The following |
77 |
|
|
pattern matches the filename (note, there is a single space at the very |
78 |
|
|
end): |
79 |
|
|
|
80 |
|
|
URxvt.selection.pattern-0: ^(/[^:]+):\ |
81 |
|
|
|
82 |

101 |
|
|
|
102 |

Other extensions can extend this popup menu by pushing a code reference |
103 |
|
|
onto C<@{ $term->{option_popup_hook} }>, which gets called whenever the |
104 |
|
|
popup is being displayed. |
105 |

Its sole argument is the popup menu, which can be modified. It should |
107 |
root |
1.133 |
either return nothing or a string, the initial boolean value and a code |
108 |
|

reference. The string will be used as button text and the code reference |
109 |

will be called when the toggle changes, with the new boolean value as |
110 |
|

root |
1.75 |
text into various other formats/action (such as uri unescaping, perl |
123 |
ayin |

Other extensions can extend this popup menu by pushing a code reference |
126 |

popup is being displayed. |
128 |
root |
1.101 |

129 |
ayin |
1.158 |
Its sole argument is the popup menu, which can be modified. The selection |
130 |
root |
1.144 |
is in C<$_>, which can be used to decide whether to add something or not. |
131 |
root |
1.101 |
It should either return nothing or a string and a code reference. The |
132 |
|
|
string will be used as button text and the code reference will be called |
133 |
|
|
when the button gets activated and should transform C<$_>. |
134 |
|
|
|
135 |
|
|
The following will add an entry C<a to b> that transforms all C<a>s in |
136 |
|
|
the selection to C<b>s, but only if the selection currently contains any |
137 |
|
|
C<a>s: |
138 |

=item searchable-scrollback<hotkey> (enabled by default) |
145 |
root |
1.69 |
|
146 |
root |
1.74 |
Adds regex search functionality to the scrollback buffer, triggered |
147 |
root |
1.87 |
by a hotkey (default: C<M-s>). While in search mode, normal terminal |
148 |
|
|
input/output is suspended and a regex is displayed at the bottom of the |
149 |
|
|
screen. |
150 |
|
|
|
151 |
|
|
Inputting characters appends them to the regex and continues incremental |
152 |
|
|
search. C<BackSpace> removes a character from the regex, C<Up> and C<Down> |
153 |
|
|
search upwards/downwards in the scrollback buffer, C<End> jumps to the |
154 |
|
|
bottom. C<Escape> leaves search mode and returns to the point where search |
155 |
|
|
was started, while C<Enter> or C<Return> stay at the current position and |
156 |
|
|
additionally stores the first match in the current line into the primary |
157 |
ayin |
1.156 |
selection if the C<Shift> modifier is active. |
158 |
root |
1.69 |
|
159 |
root |
1.142 |
The regex defaults to "(?i)", resulting in a case-insensitive search. To |
160 |
|
|
get a case-sensitive search you can delete this prefix using C<BackSpace> |
161 |
|
|
or simply use an uppercase character which removes the "(?i)" prefix. |
162 |
|
|
|
163 |
|
|
See L<perlre> for more info about perl regular expression syntax. |
164 |
|
|
|
165 |
root |
1.123 |
=item readline (enabled by default) |
166 |
|
|
|
167 |
root |
1.135 |
A support package that tries to make editing with readline easier. At |
168 |
|
|
the moment, it reacts to clicking shift-left mouse button by trying to |
169 |
root |
1.123 |
move the text cursor to this position. It does so by generating as many |
170 |
ayin |
1.161 |
cursor-left or cursor-right keypresses as required (this only works |
171 |
root |
1.123 |
for programs that correctly support wide characters). |
172 |
|
|
|
173 |
|
|
To avoid too many false positives, this is only done when: |
174 |
|
|
|
175 |
|
|
=over 4 |
176 |
|
|
|
177 |
root |
1.125 |
=item - the tty is in ICANON state. |
178 |
|
|
|
179 |
|
|
=item - the text cursor is visible. |
180 |
root |
1.123 |
|
181 |
|
|
=item - the primary screen is currently being displayed. |
182 |
|
|
|
183 |
root |
1.125 |
=item - the mouse is on the same (multi-row-) line as the text cursor. |
184 |
root |
1.123 |
|
185 |
|
|
=back |
186 |
|
|
|
187 |
|
|
The normal selection mechanism isn't disabled, so quick successive clicks |
188 |
|
|
might interfere with selection creation in harmless ways. |
189 |
|
|
|
190 |
root |
1.88 |
=item selection-autotransform |
191 |
|
|
|
192 |
|
|
This selection allows you to do automatic transforms on a selection |
193 |
|
|
whenever a selection is made. |
194 |
|
|
|
195 |
|
|
It works by specifying perl snippets (most useful is a single C<s///> |
196 |
|
|
operator) that modify C<$_> as resources: |
197 |
|
|
|
198 |
|
|
URxvt.selection-autotransform.0: transform |
199 |
|
|
URxvt.selection-autotransform.1: transform |
200 |
|
|
... |
201 |
|
|
|
202 |
|
|
For example, the following will transform selections of the form |
203 |
root |
1.89 |
C<filename:number>, often seen in compiler messages, into C<vi +$filename |
204 |
|
|
$word>: |
205 |
root |
1.88 |
|
206 |
root |
1.93 |
URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
207 |
root |
1.88 |
|
208 |
|
|
And this example matches the same,but replaces it with vi-commands you can |
209 |
root |
1.89 |
paste directly into your (vi :) editor: |
210 |
root |
1.15 |
|
211 |
root |
1.108 |
URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/ |
212 |
root |
1.20 |
|
213 |
root |
1.90 |
Of course, this can be modified to suit your needs and your editor :) |
214 |
|
|
|
215 |
root |
1.91 |
To expand the example above to typical perl error messages ("XXX at |
216 |
|
|
FILENAME line YYY."), you need a slightly more elaborate solution: |
217 |
|
|
|
218 |
root |
1.108 |
URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) |
219 |
|
|
URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/ |
220 |
root |
1.91 |
|
221 |
|
|
The first line tells the selection code to treat the unchanging part of |
222 |
|
|
every error message as a selection pattern, and the second line transforms |
223 |
|
|
the message into vi commands to load the file. |
224 |
|
|
|
225 |
root |
1.115 |
=item tabbed |
226 |
|
|
|
227 |
|
|
This transforms the terminal into a tabbar with additional terminals, that |
228 |
root |
1.144 |
is, it implements what is commonly referred to as "tabbed terminal". The topmost line |
229 |
root |
1.115 |
displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
230 |
|
|
button per tab. |
231 |
|
|
|
232 |
root |
1.116 |
Clicking a button will activate that tab. Pressing B<Shift-Left> and |
233 |
|
|
B<Shift-Right> will switch to the tab left or right of the current one, |
234 |
|
|
while B<Shift-Down> creates a new tab. |
235 |
root |
1.115 |
|
236 |
root |
1.132 |
The tabbar itself can be configured similarly to a normal terminal, but |
237 |
|
|
with a resource class of C<URxvt.tabbed>. In addition, it supports the |
238 |
|
|
following four resources (shown with defaults): |
239 |
|
|
|
240 |
|
|
URxvt.tabbed.tabbar-fg: <colour-index, default 3> |
241 |
|
|
URxvt.tabbed.tabbar-bg: <colour-index, default 0> |
242 |
|
|
URxvt.tabbed.tab-fg: <colour-index, default 0> |
243 |
|
|
URxvt.tabbed.tab-bg: <colour-index, default 1> |
244 |

=item matcher |
249 |
root |
1.35 |
|
250 |
root |
1.147 |
Uses per-line display filtering (C<on_line_update>) to underline text |
251 |
|
|
matching a certain pattern and make it clickable. When clicked with the |
252 |
|
|
mouse button specified in the C<matcher.button> resource (default 2, or |
253 |
|
|
middle), the program specified in the C<matcher.launcher> resource |
254 |
|
|
(default, the C<urlLauncher> resource, C<sensible-browser>) will be started |
255 |
|
|
with the matched text as first argument. The default configuration is |
256 |
|
|
suitable for matching URLs and launching a web browser, like the |
257 |
|
|
former "mark-urls" extension. |
258 |
|
|
|
259 |
|
|
The default pattern to match URLs can be overridden with the |
260 |
|
|
C<matcher.pattern.0> resource, and additional patterns can be specified |
261 |
|
|
with numbered patterns, in a manner similar to the "selection" extension. |
262 |
|
|
The launcher can also be overridden on a per-pattern basis. |
263 |

It is possible to activate the most recently seen match or a list of matches |

=item kuake<hotkey> |
292 |
|
|
|
293 |
|
|
A very primitive quake-console-like extension. It was inspired by a |
294 |
|
|
description of how the programs C<kuake> and C<yakuake> work: Whenever the |
295 |
|
|
user presses a global accelerator key (by default C<F10>), the terminal |
296 |
|
|
will show or hide itself. Another press of the accelerator key will hide |
297 |
|
|
or show it again. |
298 |

Initially, the window will not be shown when using this extension. |

The accelerator key is grabbed regardless of any modifiers, so this |

This extension implements some OSC commands to display timed popups on the |

|
Somewhat of a misnomer, this extension adds two menu entries to the |
329 |
ayin |
1.158 |
selection popup that allows one to run external commands to store the |
330 |
root |
1.129 |
selection somewhere and fetch it again. |
331 |
|
|
|
332 |
|
|
We use it to implement a "distributed selection mechanism", which just |
333 |
|
|
means that one command uploads the file to a remote server, and another |
334 |
|
|
reads it. |
335 |
|
|
|
336 |
|
|
The commands can be set using the C<URxvt.remote-selection.store> and |
337 |
|
|
C<URxvt.remote-selection.fetch> resources. The first should read the |
338 |
|
|
selection to store from STDIN (always in UTF-8), the second should provide |
339 |
|
|
the selection data on STDOUT (also in UTF-8). |
340 |

sf-exg |
1.182 |
This is a little rarely useful extension that uploads the selection as |
349 |
root |
1.99 |
textfile to a remote site (or does other things). (The implementation is |
350 |
|
|
not currently secure for use in a multiuser environment as it writes to |
351 |
|
|
F</tmp> directly.). |
352 |
root |
1.98 |
|
353 |
|
|
It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
354 |
|
|
i.e. |
355 |
elmex |
1.97 |
|
356 |
|
|
URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
357 |
|
|
|
358 |
root |
1.98 |
Pressing this combination runs a command with C<%> replaced by the name of |
359 |
|
|
the textfile. This command can be set via a resource: |
360 |
|
|
|
361 |
|
|
URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
362 |
|
|
|
363 |
|
|
And the default is likely not useful to anybody but the few people around |
364 |
|
|
here :) |
365 |
elmex |
1.97 |
|
366 |
root |
1.98 |
The name of the textfile is the hex encoded md5 sum of the selection, so |
367 |
|
|
the same content should lead to the same filename. |
368 |
elmex |
1.97 |
|
369 |
root |
1.98 |
After a successful upload the selection will be replaced by the text given |
370 |
|
|
in the C<selection-pastebin-url> resource (again, the % is the placeholder |
371 |
|
|
for the filename): |

These two modules implement an extended clipboard for Mac OS X. They are |

|
|
URxvt.keysym.M-v: perl:macosx-clipboard:paste |
388 |
|
|
|
389 |
|
|
The difference between them is that the native variant requires a |
390 |
sf-exg |
1.182 |
perl from apple's devkit or so, and C<macosx-clipboard> requires the |
391 |
root |

All objects (such as terminals, time watchers etc.) are typical |
420 |
|
|
reference-to-hash objects. The hash can be used to store anything you |
421 |
root |
1.7 |
like. All members starting with an underscore (such as C<_ptr> or |
422 |
root |
1.23 |
C<_hook>) are reserved for internal uses and B<MUST NOT> be accessed or |
423 |
root |
1.7 |
modified). |
424 |
root |
1.6 |
|
425 |
|
|
When objects are destroyed on the C++ side, the perl object hashes are |
426 |
|
|
emptied, so its best to store related objects such as time watchers and |
427 |
|
|
the like inside the terminal object so they get destroyed as soon as the |
428 |
|
|
terminal is destroyed. |

Every perl extension is a perl class. A separate perl object is created |
462 |
sf-exg |
1.193 |
for each terminal, and each terminal has its own set of extension objects, |
463 |
root |
1.145 |
which are passed as the first parameter to hooks. So extensions can use |
464 |
|
|
their C<$self> object without having to think about clashes with other |
465 |
|
|
extensions or other terminals, with the exception of methods and members |
466 |
|
|
that begin with an underscore character C<_>: these are reserved for |
467 |
|
|
internal use. |

root |
1.171 |
string should start with the extension name (sans -osc) and a semicolon, |

Called whenever text is about to be output, with the text as argument. You |
626 |
|
|
can filter/change and output the text yourself by returning a true value |
627 |
|
|
and calling C<< $term->scr_add_lines >> yourself. Please note that this |
628 |

can filter/change and paste the text yourself by returning a true value |
640 |

645 |
|
|
Called whenever a line was updated or changed. Can be used to filter |
646 |
|
|
screen output (e.g. underline urls or other useless stuff). Only lines |
647 |
|
|
that are being shown will be filtered, and, due to performance reasons, |
648 |
|
|
not always immediately. |
649 |
|
|
|
650 |
|
|
The row number is always the topmost row of the line if the line spans |
651 |
|
|
multiple rows. |
652 |

653 |
|
|
Please note that, if you change the line, then the hook might get called |
654 |

later with the already-modified line (e.g. if unrelated parts change), so |
655 |

you cannot just toggle rendition bits, but only set them. |

Fatally aborts execution with the given error message (which should |
827 |
|
|
include a trailing newline). Avoid at all costs! The only time this |
828 |
|
|
is acceptable (and useful) is in the init hook, where it prevents the |

835 |

Using this function has the advantage that its output ends up in the |

C<AnyEvent> module - any module using it will work inside urxvt without |

further programming. The only exception is that you cannot wait on |

condition variables, but non-blocking condvar use is ok. What this means |

|
|
is that you cannot use blocking APIs, but the non-blocking variant should |

work. |

|
Returns the current resource value associated with a given name and |
1348 |

optionally sets a new value. Setting values is most useful in the C<init> |
1349 |
|
|
hook. Unset resources are returned and accepted as C<undef>. |
1350 |
|
|
|
1351 |
|
|
The new value must be properly encoded to a suitable character encoding |
1352 |

before passing it to this method. Similarly, the returned value may need |
1353 |
|
|
to be converted from the used encoding to text. |

|
Resource names are as defined in F<src/rsinc.h>. Colours can be specified |
1356 |

as resource names of the form C<< color+<index> >>, e.g. C<color+5>. (will |

likely change). |

|
|
XORs the rendition values in the given span with the provided value |
1560 |

Similar to C<scr_xor_span>, but xors a rectangle instead. Trailing |

Write the given text string to the screen, as if output by the application |

running inside the terminal. It may not contain command sequences (escape |
1578 |

codes), but is free to use line feeds, carriage returns and tabs. The |
1579 |

string is a normal text string, not in locale-dependent encoding. |

Normally its not a good idea to use this function, as programs might be |

Returns the text of the entire row with number C<$row_number>. Row C<< $term->top_row >> |

If C<$new_text> is specified, it will replace characters in the current |
1737 |
|
|
line, starting at column C<$start_col> (default C<0>), which is useful |
1738 |

C<$text> is in a special encoding: tabs and wide characters that use more |

than one cell when displayed are padded with C<$urxvt::NOCHAR> (chr 65535) |
1743 |
root |

characters. Characters with combining characters and other characters that |
1744 |
ayin |

root |
1.121 |
in the private use area. |

You have to obey this encoding when changing text. The advantage is |
