175 root 1.16 .IP "selection (enabled by default)" 4
176     .IX Item "selection (enabled by default)"
177 root 1.20 (More) intelligent selection. This extension tries to be more intelligent
178 root 1.25 when the user extends selections (double\-click and further clicks). Right
179     now, it tries to select words, urls and complete shell-quoted
180     arguments, which is very convenient, too, if your \fIls\fR supports
181     \&\f(CW\*(C`\-\-quoting\-style=shell\*(C'\fR.
182     .Sp
183     A double-click usually selects the word under the cursor, further clicks
184     will enlarge the selection.
185 root 1.9 .Sp
186 root 1.26 The selection works by trying to match a number of regexes and displaying
187     them in increasing order of length. You can add your own regexes by
188     specifying resources of the form:
189     .Sp
190     .Vb 3
191     \& URxvt.selection.pattern-0: perl-regex
192     \& URxvt.selection.pattern-1: perl-regex
193     \& ...
194     .Ve
195     .Sp
196     The index number (0, 1...) must not have any holes, and each regex must
197     contain at least one pair of capturing parentheses, which will be used for
198     the match. For example, the followign adds a regex that matches everything
199     between two vertical bars:
200     .Sp
201     .Vb 1
202     \& URxvt.selection.pattern-0: \e\e|([^|]+)\e\e|
203     .Ve
204     .Sp
205     You can look at the source of the selection extension to see more
206     interesting uses, such as parsing a line from beginning to end.

220 root 1.16 .IP "option-popup (enabled by default)" 4
221     .IX Item "option-popup (enabled by default)"
222 root 1.17 Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at
223 root 1.16 runtime.
224 root 1.17 .IP "selection-popup (enabled by default)" 4
225     .IX Item "selection-popup (enabled by default)"
226     Binds a popup menu to Ctrl\-Button3 that lets you convert the selection
227 root 1.20 text into various other formats/action (such as uri unescaping, perl
228     evalution, web-browser starting etc.), depending on content.
229 root 1.34 .Sp
230     Other extensions can extend this popup menu by pushing a code reference
231     onto \f(CW\*(C`@{ $term\-\*(C'\fR{selection_popup_hook} }>, that is called whenever the
232     popup is displayed.
233     .Sp
234     It's sole argument is the popup menu, which can be modified. The selection
235     is in \f(CW$_\fR, which can be used to decide wether to add something or not.
236     It should either return nothing or a string and a code reference. The
237     string will be used as button text and the code reference will be called
238     when the button gets activated and should transform \f(CW$_\fR.
239     .Sp
240     The following will add an entry \f(CW\*(C`a to b\*(C'\fR that transforms all \f(CW\*(C`a\*(C'\fRs in
241     the selection to \f(CW\*(C`b\*(C'\fRs, but only if the selection currently contains any
242     \&\f(CW\*(C`a\*(C'\fRs:
243     .Sp
244     .Vb 4
245     \& push @{ $self->{term}{selection_popup_hook} }, sub {
246     \& /a/ ? ("a to be" => sub { s/a/b/g }

248     \& };
249     .Ve
250 root 1.19 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
251     .IX Item "searchable-scrollback<hotkey> (enabled by default)"
252     Adds regex search functionality to the scrollback buffer, triggered
253 root 1.25 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
254     input/output is suspended and a regex is displayed at the bottom of the
255     screen.
256     .Sp
257     Inputting characters appends them to the regex and continues incremental
258     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
259     search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
260     bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
261     was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
262     additionally stores the first match in the current line into the primary
263     selection.
264 root 1.26 .IP "selection-autotransform" 4
265     .IX Item "selection-autotransform"
266     This selection allows you to do automatic transforms on a selection
267     whenever a selection is made.
268     .Sp
269     It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
270     operator) that modify \f(CW$_\fR as resources:
271     .Sp
272     .Vb 3
273     \& URxvt.selection-autotransform.0: transform
274     \& URxvt.selection-autotransform.1: transform
275     \& ...
276     .Ve
277     .Sp
278     For example, the following will transform selections of the form
279     \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
280     $word\*(C'\fR:
281     .Sp
282     .Vb 1
283 root 1.29 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
284 root 1.26 .Ve
285     .Sp
286     And this example matches the same,but replaces it with vi-commands you can
287     paste directly into your (vi :) editor:
288     .Sp
289     .Vb 1
290 root 1.34 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
291 root 1.26 .Ve
292 root 1.27 .Sp
293     Of course, this can be modified to suit your needs and your editor :)
294 root 1.28 .Sp
295     To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at
296     \&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution:
297     .Sp
298     .Vb 2
299 root 1.34 \& URxvt.selection.pattern-0: ( at .*? line \e\ed+[,.])
300     \& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)[,.]$/:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/
301 root 1.28 .Ve
302     .Sp
303     The first line tells the selection code to treat the unchanging part of
304     every error message as a selection pattern, and the second line transforms
305     the message into vi commands to load the file.
306 root 1.14 .IP "mark-urls" 4
307     .IX Item "mark-urls"
308 root 1.24 Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline urls and
309 root 1.25 make them clickable. When middle\-clicked, the program specified in the
310     resource \f(CW\*(C`urlLauncher\*(C'\fR (default \f(CW\*(C`x\-www\-browser\*(C'\fR) will be started with
311     the \s-1URL\s0 as first argument.
312 root 1.34 .IP "automove-background" 4
313     .IX Item "automove-background"
314     This is basically a one-line extension that dynamically changes the background pixmap offset
315     to the window position, in effect creating the same effect as pseudo transparency with
316     a custom pixmap. No scaling is supported in this mode. Exmaple:
317     .Sp
318     .Vb 1
319     \& @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
320     .Ve
321 root 1.14 .IP "block-graphics-to-ascii" 4
322     .IX Item "block-graphics-to-ascii"
323     A not very useful example of filtering all text output to the terminal,
324     by replacing all line-drawing characters (U+2500 .. U+259F) by a
325     similar-looking ascii character.
326 root 1.26 .IP "digital-clock" 4
327     .IX Item "digital-clock"
328     Displays a digital clock using the built-in overlay.
329 root 1.8 .IP "example-refresh-hooks" 4
330     .IX Item "example-refresh-hooks"
331 root 1.6 Displays a very simple digital clock in the upper right corner of the
332     window. Illustrates overwriting the refresh callbacks to create your own
333     overlays or changes.
334 root 1.33 .IP "selection-pastebin" 4
335     .IX Item "selection-pastebin"
336     This is a little rarely useful extension that Uploads the selection as
337     textfile to a remote site (or does other things). (The implementation is
338     not currently secure for use in a multiuser environment as it writes to
339     \&\fI/tmp\fR directly.).
340     .Sp
341     It listens to the \f(CW\*(C`selection\-pastebin:remote\-pastebin\*(C'\fR keyboard command,
342     i.e.
343     .Sp
344     .Vb 1
345     \& URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
346     .Ve
347     .Sp
348     Pressing this combination runs a command with \f(CW\*(C`%\*(C'\fR replaced by the name of
349     the textfile. This command can be set via a resource:
350     .Sp
351     .Vb 1
352     \& URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
353     .Ve
354     .Sp
355     And the default is likely not useful to anybody but the few people around
356     here :)
357     .Sp
358     The name of the textfile is the hex encoded md5 sum of the selection, so
359     the same content should lead to the same filename.
360     .Sp
361     After a successful upload the selection will be replaced by the text given
362     in the \f(CW\*(C`selection\-pastebin\-url\*(C'\fR resource (again, the % is the placeholder
363     for the filename):
364     .Sp
365     .Vb 1
366     \& URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

371     .IX Subsection "General API Considerations"
372     All objects (such as terminals, time watchers etc.) are typical
373     reference-to-hash objects. The hash can be used to store anything you
374     like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
375 root 1.9 \&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or
376 root 1.3 modified).
377     .PP
378     When objects are destroyed on the \*(C+ side, the perl object hashes are
379     emptied, so its best to store related objects such as time watchers and
380     the like inside the terminal object so they get destroyed as soon as the
381     terminal is destroyed.

389 root 1.14 .IP "$string" 4
390     .IX Item "$string"
391     A perl text string, with an emphasis on \fItext\fR. It can store all unicode
392     characters and is to be distinguished with text encoded in a specific

400     Very perl extension is a perl class. A separate perl object is created
401     for each terminal and each extension and passed as the first parameter to
402     hooks. So extensions can use their \f(CW$self\fR object without having to think
403     about other extensions, with the exception of methods and members that
404     begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
