52C<--quoting-style=shell>.
48 53
49It also offers the following bindable event: 54A double-click usually selects the word under the cursor, further clicks
55will enlarge the selection.
56
57The selection works by trying to match a number of regexes and displaying
58them in increasing order of length. You can add your own regexes by
59specifying resources of the form:
60
61 URxvt.selection.pattern-0: perl-regex
62 URxvt.selection.pattern-1: perl-regex
63 ...
64
65The index number (0, 1...) must not have any holes, and each regex must
66contain at least one pair of capturing parentheses, which will be used for
67the match. For example, the followign adds a regex that matches everything
68between two vertical bars:
69
70 URxvt.selection.pattern-0: \\|([^|]+)\\|
71
72You can look at the source of the selection extension to see more
73interesting uses, such as parsing a line from beginning to end.
74
75This extension also offers following bindable keyboard commands:

65 91
66=item digital-clock 92=item selection-popup (enabled by default)
67 93
68Displays a digital clock using the built-in overlay. 94Binds a popup menu to Ctrl-Button3 that lets you convert the selection
95text into various other formats/action (such as uri unescaping, perl
96evaluation, web-browser starting etc.), depending on content.
97
98Other extensions can extend this popup menu by pushing a code reference
99onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
100popup is displayed.
101
102It's sole argument is the popup menu, which can be modified. The selection
103is in C<$_>, which can be used to decide wether to add something or not.
104It should either return nothing or a string and a code reference. The
105string will be used as button text and the code reference will be called
106when the button gets activated and should transform C<$_>.
107
108The following will add an entry C<a to b> that transforms all C<a>s in
109the selection to C<b>s, but only if the selection currently contains any
110C<a>s:
111
112 push @{ $self->{term}{selection_popup_hook} }, sub {
113 /a/ ? ("a to be" => sub { s/a/b/g }
114 : ()
115 };
116
117=item searchable-scrollback<hotkey> (enabled by default)
118
119Adds regex search functionality to the scrollback buffer, triggered
120by a hotkey (default: C<M-s>). While in search mode, normal terminal
121input/output is suspended and a regex is displayed at the bottom of the
122screen.
123
124Inputting characters appends them to the regex and continues incremental
125search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
126search upwards/downwards in the scrollback buffer, C<End> jumps to the
127bottom. C<Escape> leaves search mode and returns to the point where search
128was started, while C<Enter> or C<Return> stay at the current position and
129additionally stores the first match in the current line into the primary
130selection.
131
132=item readline (enabled by default)
133
134A support package that tries to make editing with readline easier. At the
135moment, it reacts to clicking with the left mouse button by trying to
136move the text cursor to this position. It does so by generating as many
137cursor-left or cursor-right keypresses as required (the this only works
138for programs that correctly support wide characters).
139
140To avoid too many false positives, this is only done when:
141
142=over 4
143
144=item - the mouse is on the same (multi-row-) line as the text cursor.
145
146=item - the primary screen is currently being displayed.
147
148=item - the text cursor is visible.
149
150=back
151
152The normal selection mechanism isn't disabled, so quick successive clicks
153might interfere with selection creation in harmless ways.
154
155=item selection-autotransform
156
157This selection allows you to do automatic transforms on a selection
158whenever a selection is made.
159
160It works by specifying perl snippets (most useful is a single C<s///>
161operator) that modify C<$_> as resources:
162
163 URxvt.selection-autotransform.0: transform
164 URxvt.selection-autotransform.1: transform
165 ...
166
167For example, the following will transform selections of the form
168C<filename:number>, often seen in compiler messages, into C<vi +$filename
169$word>:
170
171 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
172
173And this example matches the same,but replaces it with vi-commands you can
174paste directly into your (vi :) editor:
175
176 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
177
178Of course, this can be modified to suit your needs and your editor :)
179
180To expand the example above to typical perl error messages ("XXX at
181FILENAME line YYY."), you need a slightly more elaborate solution:
182
183 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
184 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
185
186The first line tells the selection code to treat the unchanging part of
187every error message as a selection pattern, and the second line transforms
188the message into vi commands to load the file.
189
190=item tabbed
191
192This transforms the terminal into a tabbar with additional terminals, that
193is, it implements what is commonly refered to as "tabbed terminal". The topmost line
194displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
195button per tab.
196
197Clicking a button will activate that tab. Pressing B<Shift-Left> and
198B<Shift-Right> will switch to the tab left or right of the current one,
199while B<Shift-Down> creates a new tab.

72Uses per-line display filtering (C<on_line_update>) to underline urls. 203Uses per-line display filtering (C<on_line_update>) to underline urls and
204make them clickable. When middle-clicked, the program specified in the
205resource C<urlLauncher> (default C<x-www-browser>) will be started with
206the URL as first argument.
207
208=item automove-background
209
210This is basically a one-line extension that dynamically changes the background pixmap offset
211to the window position, in effect creating the same effect as pseudo transparency with
212a custom pixmap. No scaling is supported in this mode. Exmaple:

85 231
232=item selection-pastebin
233
234This is a little rarely useful extension that Uploads the selection as
235textfile to a remote site (or does other things). (The implementation is
236not currently secure for use in a multiuser environment as it writes to
237F</tmp> directly.).
238
239It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
240i.e.
241
242 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
243
244Pressing this combination runs a command with C<%> replaced by the name of
245the textfile. This command can be set via a resource:
246
247 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
248
249And the default is likely not useful to anybody but the few people around
250here :)
251
252The name of the textfile is the hex encoded md5 sum of the selection, so
253the same content should lead to the same filename.
254
255After a successful upload the selection will be replaced by the text given
256in the C<selection-pastebin-url> resource (again, the % is the placeholder
257for the filename):

301=head2 Extension Objects
302
303Very perl extension is a perl class. A separate perl object is created
304for each terminal and each extension and passed as the first parameter to
305hooks. So extensions can use their C<$self> object without having to think
306about other extensions, with the exception of methods and members that
307begin with an underscore character C<_>: these are reserved for internal
308use.
309
310Although it isn't a C<urxvt::term> object, you can call all methods of the
311C<urxvt::term> class on this object.
