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.
207     .Sp
208 root 1.32 This extension also offers following bindable keyboard commands:
209 root 1.6 .RS 4
210     .IP "rot13" 4
211     .IX Item "rot13"
212     Rot\-13 the selection when activated. Used via keyboard trigger:

221     .Vb 1
222     \& URxvt.keysym.C-M-e: perl:selection:remote-pastebin
223     .Ve

225     To set the command to upload the file set this resource:

231     The % is the placeholder for the textfile. The name of the textfile is the hex encoded
232     md5 sum of the selection.
233     After an successful upload the selection will be replaced by the following url
234     (the % is the placeholder for the filename):

246 root 1.17 .IP "selection-popup (enabled by default)" 4
247     .IX Item "selection-popup (enabled by default)"
248     Binds a popup menu to Ctrl\-Button3 that lets you convert the selection
249 root 1.20 text into various other formats/action (such as uri unescaping, perl
250     evalution, web-browser starting etc.), depending on content.
251 root 1.19 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
252     .IX Item "searchable-scrollback<hotkey> (enabled by default)"
253     Adds regex search functionality to the scrollback buffer, triggered
254 root 1.25 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
255     input/output is suspended and a regex is displayed at the bottom of the
256     screen.
257     .Sp
258     Inputting characters appends them to the regex and continues incremental
259     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
260     search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
261     bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
262     was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
263     additionally stores the first match in the current line into the primary
264     selection.
265 root 1.26 .IP "selection-autotransform" 4
266     .IX Item "selection-autotransform"
267     This selection allows you to do automatic transforms on a selection
268     whenever a selection is made.
269     .Sp
270     It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
271     operator) that modify \f(CW$_\fR as resources:
272     .Sp
273     .Vb 3
274     \& URxvt.selection-autotransform.0: transform
275     \& URxvt.selection-autotransform.1: transform
276     \& ...
277     .Ve
278     .Sp
279     For example, the following will transform selections of the form
280     \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
281     $word\*(C'\fR:
282     .Sp
283     .Vb 1
284 root 1.29 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
285 root 1.26 .Ve
286     .Sp
287     And this example matches the same,but replaces it with vi-commands you can
288     paste directly into your (vi :) editor:
289     .Sp
290     .Vb 1
291 root 1.29 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/\e\ex1b:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
292 root 1.26 .Ve
293 root 1.27 .Sp
294     Of course, this can be modified to suit your needs and your editor :)
295 root 1.28 .Sp
296     To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at
297     \&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution:
298     .Sp
299     .Vb 2
300     \& URxvt.selection.pattern-0: ( at .*? line \e\ed+\e\e.)
301     \& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)\e\e.$/\ex1b:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/
302     .Ve
303     .Sp
304     The first line tells the selection code to treat the unchanging part of
305     every error message as a selection pattern, and the second line transforms
306     the message into vi commands to load the file.
307 root 1.14 .IP "mark-urls" 4
308     .IX Item "mark-urls"
309 root 1.24 Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline urls and
310 root 1.25 make them clickable. When middle\-clicked, the program specified in the
311     resource \f(CW\*(C`urlLauncher\*(C'\fR (default \f(CW\*(C`x\-www\-browser\*(C'\fR) will be started with
312     the \s-1URL\s0 as first argument.
313 root 1.14 .IP "block-graphics-to-ascii" 4
314     .IX Item "block-graphics-to-ascii"
315     A not very useful example of filtering all text output to the terminal,
316     by replacing all line-drawing characters (U+2500 .. U+259F) by a
317     similar-looking ascii character.
318 root 1.26 .IP "digital-clock" 4
319     .IX Item "digital-clock"
320     Displays a digital clock using the built-in overlay.
321 root 1.8 .IP "example-refresh-hooks" 4
322     .IX Item "example-refresh-hooks"
323 root 1.6 Displays a very simple digital clock in the upper right corner of the
324     window. Illustrates overwriting the refresh callbacks to create your own
325     overlays or changes.
326 root 1.20 .SH "API DOCUMENTATION"
327     .IX Header "API DOCUMENTATION"
328 root 1.3 .Sh "General \s-1API\s0 Considerations"
329     .IX Subsection "General API Considerations"
330     All objects (such as terminals, time watchers etc.) are typical
331     reference-to-hash objects. The hash can be used to store anything you
332     like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
333 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
334 root 1.3 modified).
335     .PP
336     When objects are destroyed on the \*(C+ side, the perl object hashes are
337     emptied, so its best to store related objects such as time watchers and
338     the like inside the terminal object so they get destroyed as soon as the
339     terminal is destroyed.
340 root 1.14 .PP
341     Argument names also often indicate the type of a parameter. Here are some
342     hints on what they mean:
343     .IP "$text" 4
344     .IX Item "$text"
345     Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
346 root 1.23 always represents one screen cell. See ROW_t for a discussion of this format.
347 root 1.14 .IP "$string" 4
348     .IX Item "$string"
349     A perl text string, with an emphasis on \fItext\fR. It can store all unicode
350     characters and is to be distinguished with text encoded in a specific
351     encoding (often locale\-specific) and binary data.
352     .IP "$octets" 4
353     .IX Item "$octets"
354     Either binary data or \- more common \- a text string encoded in a
355     locale-specific way.
356 root 1.19 .Sh "Extension Objects"
357     .IX Subsection "Extension Objects"
358     Very perl extension is a perl class. A separate perl object is created
359     for each terminal and each extension and passed as the first parameter to
360     hooks. So extensions can use their \f(CW$self\fR object without having to think
361     about other extensions, with the exception of methods and members that
362     begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
363     use.
364     .PP
365     Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
366     \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
367     .PP
368     It has the following methods and data members:
369     .ie n .IP "$urxvt_term = $self\->{term}" 4
370     .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
371     .IX Item "$urxvt_term = $self->{term}"
372     Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
373     extension. This member \fImust not\fR be changed in any way.
374     .ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4

377     Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
378     this extension, replacing any previous hook. This is useful when you want
379     to overwrite time-critical hooks only temporarily.
380     .ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
381     .el .IP "$self\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4
