.IX Item "selection (enabled by default)" |
179 |
(More) intelligent selection. This extension tries to be more intelligent |
180 |
when the user extends selections (double-click and further clicks). Right |
181 |
now, it tries to select words, urls and complete shell-quoted |
182 |
arguments, which is very convenient, too, if your \fIls\fR supports |
183 |
\&\f(CW\*(C`\-\-quoting\-style=shell\*(C'\fR. |
184 |
.Sp |
185 |
A double-click usually selects the word under the cursor, further clicks |
186 |
will enlarge the selection. |
187 |
.Sp |
188 |
The selection works by trying to match a number of regexes and displaying |
189 |
them in increasing order of length. You can add your own regexes by |
190 |
specifying resources of the form: |
191 |
.Sp |
192 |
.Vb 3 |
193 |
\& URxvt.selection.pattern\-0: perl\-regex |
194 |
\& URxvt.selection.pattern\-1: perl\-regex |
195 |
\& ... |
196 |
.Ve |
197 |
.Sp |
198 |
The index number (0, 1...) must not have any holes, and each regex must |
199 |
contain at least one pair of capturing parentheses, which will be used for |
200 |
the match. For example, the following adds a regex that matches everything |
201 |
between two vertical bars: |
202 |
.Sp |
203 |
.Vb 1 |
204 |
\& URxvt.selection.pattern\-0: \e\e|([^|]+)\e\e| |
205 |
.Ve |
206 |
.Sp |
207 |
Another example: Programs I use often output \*(L"absolute path: \*(R" at the |
208 |
beginning of a line when they process multiple files. The following |
209 |
pattern matches the filename (note, there is a single space at the very |
210 |
end): |
211 |
.Sp |
212 |
.Vb 1 |
213 |
\& URxvt.selection.pattern\-0: ^(/[^:]+):\e |
214 |

233 |
Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at |
234 |
runtime. |
235 |
.Sp |
236 |
Other extensions can extend this popup menu by pushing a code reference |
237 |
onto \f(CW\*(C`@{ $term\-\*(C'\fR{option_popup_hook} }>, which gets called whenever the |
238 |
popup is being displayed. |
239 |
.Sp |
240 |
Its sole argument is the popup menu, which can be modified. It should |
241 |
either return nothing or a string, the initial boolean value and a code |
242 |
reference. The string will be used as button text and the code reference |
243 |
will be called when the toggle changes, with the new boolean value as |
244 |
first argument. |
245 |
.Sp |
246 |

256 |
Binds a popup menu to Ctrl\-Button3 that lets you convert the selection |
257 |
text into various other formats/action (such as uri unescaping, perl |
258 |
evaluation, web-browser starting etc.), depending on content. |
259 |
.Sp |
260 |
Other extensions can extend this popup menu by pushing a code reference |
261 |
onto \f(CW\*(C`@{ $term\-\*(C'\fR{selection_popup_hook} }>, which gets called whenever the |
262 |
popup is being displayed. |
263 |
.Sp |
264 |
Its sole argument is the popup menu, which can be modified. The selection |
265 |
is in \f(CW$_\fR, which can be used to decide whether to add something or not. |
266 |
It should either return nothing or a string and a code reference. The |
267 |
string will be used as button text and the code reference will be called |
268 |
when the button gets activated and should transform \f(CW$_\fR. |
269 |
.Sp |
270 |
The following will add an entry \f(CW\*(C`a to b\*(C'\fR that transforms all \f(CW\*(C`a\*(C'\fRs in |

.IP "searchable\-scrollback<hotkey> (enabled by default)" 4 |
281 |
.IX Item "searchable-scrollback<hotkey> (enabled by default)" |
282 |
Adds regex search functionality to the scrollback buffer, triggered |
283 |
by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal |
284 |
input/output is suspended and a regex is displayed at the bottom of the |
285 |
screen. |
286 |
.Sp |
287 |
Inputting characters appends them to the regex and continues incremental |
288 |
search. \f(CW\*(C`BackSpace\*(C'\fR removes a character from the regex, \f(CW\*(C`Up\*(C'\fR and \f(CW\*(C`Down\*(C'\fR |
289 |
search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the |
290 |
bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search |
291 |
was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and |
292 |
additionally stores the first match in the current line into the primary |
293 |
selection if the \f(CW\*(C`Shift\*(C'\fR modifier is active. |
294 |
.Sp |
295 |
The regex defaults to \*(L"(?i)\*(R", resulting in a case-insensitive search. To |
296 |
get a case-sensitive search you can delete this prefix using \f(CW\*(C`BackSpace\*(C'\fR |
297 |
or simply use an uppercase character which removes the \*(L"(?i)\*(R" prefix. |

.IX Item "readline (enabled by default)" |
302 |
A support package that tries to make editing with readline easier. At |
303 |
the moment, it reacts to clicking shift-left mouse button by trying to |
304 |
move the text cursor to this position. It does so by generating as many |
305 |
cursor-left or cursor-right keypresses as required (this only works |
306 |
for programs that correctly support wide characters). |
307 |

.IP "selection-autotransform" 4 |
327 |
.IX Item "selection-autotransform" |
328 |
This selection allows you to do automatic transforms on a selection |
329 |
whenever a selection is made. |
330 |
.Sp |
331 |
It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR |
332 |
operator) that modify \f(CW$_\fR as resources: |
333 |
.Sp |
334 |
.Vb 3 |
335 |
\& URxvt.selection\-autotransform.0: transform |
336 |
\& URxvt.selection\-autotransform.1: transform |
337 |
\& ... |
338 |
.Ve |
339 |
.Sp |
340 |
For example, the following will transform selections of the form |
341 |
\&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename |
342 |
$word\*(C'\fR: |
343 |
.Sp |
344 |
.Vb 1 |
345 |
\& URxvt.selection\-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/ |
346 |
.Ve |
347 |
.Sp |
348 |
And this example matches the same,but replaces it with vi-commands you can |
349 |
paste directly into your (vi :) editor: |
350 |
.Sp |
351 |
.Vb 1 |
352 |
\& URxvt.selection\-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/ |
353 |
.Ve |
354 |
.Sp |
355 |
Of course, this can be modified to suit your needs and your editor :) |
356 |
.Sp |
357 |
To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at |
358 |
\&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution: |
359 |
.Sp |
360 |
.Vb 2 |
361 |
\& URxvt.selection.pattern\-0: ( at .*? line \e\ed+[,.]) |
362 |
\& URxvt.selection\-autotransform.0: s/^ at (.*?) line (\e\ed+)[,.]$/:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/ |
363 |
.Ve |
364 |
.Sp |
365 |
The first line tells the selection code to treat the unchanging part of |
366 |
every error message as a selection pattern, and the second line transforms |
367 |
the message into vi commands to load the file. |
368 |
.IP "tabbed" 4 |
369 |
.IX Item "tabbed" |
370 |
This transforms the terminal into a tabbar with additional terminals, that |
371 |
is, it implements what is commonly referred to as \*(L"tabbed terminal\*(R". The topmost line |
372 |
displays a \*(L"[\s-1NEW\s0]\*(R" button, which, when clicked, will add a new tab, followed by one |
373 |
button per tab. |
374 |
.Sp |
375 |
Clicking a button will activate that tab. Pressing \fBShift-Left\fR and |
376 |
\&\fBShift-Right\fR will switch to the tab left or right of the current one, |
377 |
while \fBShift-Down\fR creates a new tab. |
378 |
.Sp |
379 |
The tabbar itself can be configured similarly to a normal terminal, but |
380 |
with a resource class of \f(CW\*(C`URxvt.tabbed\*(C'\fR. In addition, it supports the |
381 |

matching a certain pattern and make it clickable. When clicked with the |

mouse button specified in the \f(CW\*(C`matcher.button\*(C'\fR resource (default 2, or |

.IP "kuake<hotkey>" 4 |
436 |
.IX Item "kuake<hotkey>" |
437 |
A very primitive quake-console-like extension. It was inspired by a |
438 |
description of how the programs \f(CW\*(C`kuake\*(C'\fR and \f(CW\*(C`yakuake\*(C'\fR work: Whenever the |
439 |
user presses a global accelerator key (by default \f(CW\*(C`F10\*(C'\fR), the terminal |
440 |
will show or hide itself. Another press of the accelerator key will hide |
441 |
or show it again. |
442 |
.Sp |
443 |
Initially, the window will not be shown when using this extension. |
444 |
.Sp |
445 |
This is useful if you need a single terminal that is not using any desktop |
446 |
space most of the time but is quickly available at the press of a key. |
447 |
.Sp |
448 |
The accelerator key is grabbed regardless of any modifiers, so this |
449 |
extension will actually grab a physical key just for this function. |
450 |

If you want a quake-like animation, tell your window manager to do so |
452 |
(fvwm can do it). |

467 |
.IX Item "remote-clipboard" |
468 |
Somewhat of a misnomer, this extension adds two menu entries to the |
469 |
selection popup that allows one to run external commands to store the |
470 |
selection somewhere and fetch it again. |
471 |
.Sp |
472 |
We use it to implement a \*(L"distributed selection mechanism\*(R", which just |
473 |
means that one command uploads the file to a remote server, and another |
474 |
reads it. |
475 |
.Sp |
476 |
The commands can be set using the \f(CW\*(C`URxvt.remote\-selection.store\*(C'\fR and |
477 |
\&\f(CW\*(C`URxvt.remote\-selection.fetch\*(C'\fR resources. The first should read the |
478 |
selection to store from \s-1STDIN\s0 (always in \s-1UTF\-8\s0), the second should provide |
479 |
the selection data on \s-1STDOUT\s0 (also in \s-1UTF\-8\s0). |

489 |
This is a little rarely useful extension that uploads the selection as |
490 |
textfile to a remote site (or does other things). (The implementation is |
491 |
not currently secure for use in a multiuser environment as it writes to |
492 |
\&\fI/tmp\fR directly.). |
493 |
.Sp |
494 |
It listens to the \f(CW\*(C`selection\-pastebin:remote\-pastebin\*(C'\fR keyboard command, |
495 |
i.e. |
496 |

497 |
.Vb 1 |
498 |
\& URxvt.keysym.C\-M\-e: perl:selection\-pastebin:remote\-pastebin |
499 |
.Ve |
500 |
.Sp |
501 |
Pressing this combination runs a command with \f(CW\*(C`%\*(C'\fR replaced by the name of |
502 |
the textfile. This command can be set via a resource: |
503 |
.Sp |
504 |
.Vb 1 |
505 |
\& URxvt.selection\-pastebin.cmd: rsync \-apP % ruth:/var/www/www.ta\-sa.org/files/txt/. |

.Sp |
508 |
And the default is likely not useful to anybody but the few people around |
509 |
here :) |
510 |
.Sp |
511 |
The name of the textfile is the hex encoded md5 sum of the selection, so |
512 |
the same content should lead to the same filename. |
513 |
.Sp |
514 |
After a successful upload the selection will be replaced by the text given |
515 |
in the \f(CW\*(C`selection\-pastebin\-url\*(C'\fR resource (again, the % is the placeholder |
516 |
for the filename): |

the double \f(CW\*(C`/\*(C'\fR characters as comment start. Use \f(CW\*(C`\e057\e057\*(C'\fR instead, |

554 |
All objects (such as terminals, time watchers etc.) are typical |
555 |
reference-to-hash objects. The hash can be used to store anything you |
556 |
like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or |
557 |
\&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or |
558 |
modified). |
559 |
.PP |
560 |
When objects are destroyed on the \*(C+ side, the perl object hashes are |
561 |
emptied, so its best to store related objects such as time watchers and |
562 |
the like inside the terminal object so they get destroyed as soon as the |
563 |
terminal is destroyed. |

.SS "Extension Objects" |
584 |
.IX Subsection "Extension Objects" |
585 |
Every perl extension is a perl class. A separate perl object is created |
586 |
for each terminal, and each terminal has its own set of extension objects, |
587 |
which are passed as the first parameter to hooks. So extensions can use |
588 |
their \f(CW$self\fR object without having to think about clashes with other |
589 |
extensions or other terminals, with the exception of methods and members |
590 |
that begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for |
591 |
internal use. |

operating system command) is processed. Cursor position and other state |
718 |
information is up-to-date when this happens. For interoperability, the |
719 |
string should start with the extension name (sans \-osc) and a semicolon, |
720 |
to distinguish it from commands for other extensions, and this might be |
721 |
enforced in the future. |
722 |

Called whenever text is about to be output, with the text as argument. You |
745 |
can filter/change and output the text yourself by returning a true value |
746 |
and calling \f(CW\*(C`$term\->scr_add_lines\*(C'\fR yourself. Please note that this |

758 |
can filter/change and paste the text yourself by returning a true value |

.IX Item "on_line_update $term, $row" |
764 |
Called whenever a line was updated or changed. Can be used to filter |

screen output (e.g. underline urls or other useless stuff). Only lines |
766 |
that are being shown will be filtered, and, due to performance reasons, |
767 |
not always immediately. |

The row number is always the topmost row of the line if the line spans |

772 |
Please note that, if you change the line, then the hook might get called |
