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     This extension also offers the following bindable keyboard command:
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:

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 1.19 .IP "searchable\-scrollback<hotkey> (enabled by default)" 4
230     .IX Item "searchable-scrollback<hotkey> (enabled by default)"
231     Adds regex search functionality to the scrollback buffer, triggered
232 root 1.25 by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal
233     input/output is suspended and a regex is displayed at the bottom of the
234     screen.
235     .Sp
236     Inputting characters appends them to the regex and continues incremental
237     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
238     search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the
239     bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search
240     was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and
241     additionally stores the first match in the current line into the primary
242     selection.
243 root 1.26 .IP "selection-autotransform" 4
244     .IX Item "selection-autotransform"
245     This selection allows you to do automatic transforms on a selection
246     whenever a selection is made.
247     .Sp
248     It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR
249     operator) that modify \f(CW$_\fR as resources:
250     .Sp
251     .Vb 3
252     \& URxvt.selection-autotransform.0: transform
253     \& URxvt.selection-autotransform.1: transform
254     \& ...
255     .Ve
256     .Sp
257     For example, the following will transform selections of the form
258     \&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename
259     $word\*(C'\fR:
260     .Sp
261     .Vb 1
262 root 1.29 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/
263 root 1.26 .Ve
264     .Sp
265     And this example matches the same,but replaces it with vi-commands you can
266     paste directly into your (vi :) editor:
267     .Sp
268     .Vb 1
269 root 1.29 \& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/\e\ex1b:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/
270 root 1.26 .Ve
271 root 1.27 .Sp
272     Of course, this can be modified to suit your needs and your editor :)
273 root 1.28 .Sp
274     To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at
275     \&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution:
276     .Sp
277     .Vb 2
278     \& URxvt.selection.pattern-0: ( at .*? line \e\ed+\e\e.)
279     \& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)\e\e.$/\ex1b:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/
280     .Ve
281     .Sp
282     The first line tells the selection code to treat the unchanging part of
283     every error message as a selection pattern, and the second line transforms
284     the message into vi commands to load the file.
285 root 1.14 .IP "mark-urls" 4
286     .IX Item "mark-urls"
287 root 1.24 Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline urls and
288 root 1.25 make them clickable. When middle\-clicked, the program specified in the
289     resource \f(CW\*(C`urlLauncher\*(C'\fR (default \f(CW\*(C`x\-www\-browser\*(C'\fR) will be started with
290     the \s-1URL\s0 as first argument.
291 root 1.14 .IP "block-graphics-to-ascii" 4
292     .IX Item "block-graphics-to-ascii"
293     A not very useful example of filtering all text output to the terminal,
294     by replacing all line-drawing characters (U+2500 .. U+259F) by a
295     similar-looking ascii character.
296 root 1.26 .IP "digital-clock" 4
297     .IX Item "digital-clock"
298     Displays a digital clock using the built-in overlay.
299 root 1.8 .IP "example-refresh-hooks" 4
300     .IX Item "example-refresh-hooks"
301 root 1.6 Displays a very simple digital clock in the upper right corner of the
302     window. Illustrates overwriting the refresh callbacks to create your own
303     overlays or changes.
304 root 1.20 .SH "API DOCUMENTATION"
305     .IX Header "API DOCUMENTATION"
306 root 1.3 .Sh "General \s-1API\s0 Considerations"
307     .IX Subsection "General API Considerations"
308     All objects (such as terminals, time watchers etc.) are typical
309     reference-to-hash objects. The hash can be used to store anything you
310     like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or
311 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
312 root 1.3 modified).
313     .PP
314     When objects are destroyed on the \*(C+ side, the perl object hashes are
315     emptied, so its best to store related objects such as time watchers and
316     the like inside the terminal object so they get destroyed as soon as the
317     terminal is destroyed.
318 root 1.14 .PP
319     Argument names also often indicate the type of a parameter. Here are some
320     hints on what they mean:
321     .IP "$text" 4
322     .IX Item "$text"
323     Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character
324 root 1.23 always represents one screen cell. See ROW_t for a discussion of this format.
325 root 1.14 .IP "$string" 4
326     .IX Item "$string"
327     A perl text string, with an emphasis on \fItext\fR. It can store all unicode
328     characters and is to be distinguished with text encoded in a specific
329     encoding (often locale\-specific) and binary data.
330     .IP "$octets" 4
331     .IX Item "$octets"
332     Either binary data or \- more common \- a text string encoded in a
333     locale-specific way.
334 root 1.19 .Sh "Extension Objects"
335     .IX Subsection "Extension Objects"
336     Very perl extension is a perl class. A separate perl object is created
337     for each terminal and each extension and passed as the first parameter to
338     hooks. So extensions can use their \f(CW$self\fR object without having to think
339     about other extensions, with the exception of methods and members that
340     begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal
341     use.
342     .PP
343     Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the
344     \&\f(CW\*(C`urxvt::term\*(C'\fR class on this object.
345     .PP
346     It has the following methods and data members:
347     .ie n .IP "$urxvt_term = $self\->{term}" 4
348     .el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4
349     .IX Item "$urxvt_term = $self->{term}"
350     Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the
351     extension. This member \fImust not\fR be changed in any way.
352     .ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4
353     .el .IP "$self\->enable ($hook_name => \f(CW$cb\fR, [$hook_name => \f(CW$cb\fR..])" 4
354     .IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])"
355     Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for
356     this extension, replacing any previous hook. This is useful when you want
357     to overwrite time-critical hooks only temporarily.
358     .ie n .IP "$self\->disable ($hook_name[, $hook_name..])" 4
359     .el .IP "$self\->disable ($hook_name[, \f(CW$hook_name\fR..])" 4
360     .IX Item "$self->disable ($hook_name[, $hook_name..])"
361     Dynamically disable the given hooks.
