48 53
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.

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

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.
82 131
83=item digital-clock 132=item selection-autotransform
84 133
85Displays a digital clock using the built-in overlay. 134This selection allows you to do automatic transforms on a selection
135whenever a selection is made.
136
137It works by specifying perl snippets (most useful is a single C<s///>
138operator) that modify C<$_> as resources:
139
140 URxvt.selection-autotransform.0: transform
141 URxvt.selection-autotransform.1: transform
142 ...
143
144For example, the following will transform selections of the form
145C<filename:number>, often seen in compiler messages, into C<vi +$filename
146$word>:
147
148 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
149
150And this example matches the same,but replaces it with vi-commands you can
151paste directly into your (vi :) editor:
152
153 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
154
155Of course, this can be modified to suit your needs and your editor :)
156
157To expand the example above to typical perl error messages ("XXX at
158FILENAME line YYY."), you need a slightly more elaborate solution:
159
160 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
161 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
162
163The first line tells the selection code to treat the unchanging part of
164every error message as a selection pattern, and the second line transforms
165the message into vi commands to load the file.
166
167=item readline
168
169A support package that tries to make editing with readline easier. At the
170moment, it reacts to clicking with the left mouse button by trying to
171move the text cursor to this position. It does so by generating as many
172cursor-left or cursor-right keypresses as required (the this only works
173for programs that correctly support wide characters).
174
175It only works when clicking into the same line (possibly extended over
176multiple rows) as the text cursor and on the primary screen, to reduce the
177risk of misinterpreting. The normal selection isn't disabled, so quick
178successive clicks might interfere with selection creation in harmless
179ways.
180
181=item tabbed
182
183This transforms the terminal into a tabbar with additional terminals, that
184is, it implements what is commonly refered to as "tabbed terminal". The topmost line
185displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
186button per tab.
187
188Clicking a button will activate that tab. Pressing B<Shift-Left> and
189B<Shift-Right> will switch to the tab left or right of the current one,
190while B<Shift-Down> creates a new tab.
86 191
87=item mark-urls 192=item mark-urls
88 193
89Uses per-line display filtering (C<on_line_update>) to underline urls. 194Uses per-line display filtering (C<on_line_update>) to underline urls and
195make them clickable. When middle-clicked, the program specified in the
196resource C<urlLauncher> (default C<x-www-browser>) will be started with
197the URL as first argument.
198
199=item automove-background
200
201This is basically a one-line extension that dynamically changes the background pixmap offset
202to the window position, in effect creating the same effect as pseudo transparency with
203a custom pixmap. No scaling is supported in this mode. Exmaple:

222
223=item selection-pastebin
224
225This is a little rarely useful extension that Uploads the selection as
226textfile to a remote site (or does other things). (The implementation is
227not currently secure for use in a multiuser environment as it writes to
228F</tmp> directly.).
229
230It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
231i.e.
232
233 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
234
235Pressing this combination runs a command with C<%> replaced by the name of
236the textfile. This command can be set via a resource:
237
238 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
239
240And the default is likely not useful to anybody but the few people around
241here :)
242
243The name of the textfile is the hex encoded md5 sum of the selection, so
244the same content should lead to the same filename.
245
246After a successful upload the selection will be replaced by the text given
247in the C<selection-pastebin-url> resource (again, the % is the placeholder
248for the filename):
