41 45
42=item selection (enabled by default) 46 URxvt.perl-ext-common: default,selection-autotransform
43 47
44(More) intelligent selection. This extension tries to be more intelligent 48Extensions that add command line parameters or resources on their own are
45when the user extends selections (double-click and further clicks). Right 49loaded automatically when used.
46now, it tries to select words, urls and complete shell-quoted
47arguments, which is very convenient, too, if your F<ls> supports
48C<--quoting-style=shell>.
49
50A double-click usually selects the word under the cursor, further clicks
51will enlarge the selection.
52
53The selection works by trying to match a number of regexes and displaying
54them in increasing order of length. You can add your own regexes by
55specifying resources of the form:
56
57 URxvt.selection.pattern-0: perl-regex
58 URxvt.selection.pattern-1: perl-regex
59 ...
60
61The index number (0, 1...) must not have any holes, and each regex must
62contain at least one pair of capturing parentheses, which will be used for
63the match. For example, the followign adds a regex that matches everything
64between two vertical bars:
65
66 URxvt.selection.pattern-0: \\|([^|]+)\\|
67
68You can look at the source of the selection extension to see more
69interesting uses, such as parsing a line from beginning to end.
70
71This extension also offers following bindable keyboard commands:
72
73=over 4
74
75=item rot13
76
77Rot-13 the selection when activated. Used via keyboard trigger:
78
79 URxvt.keysym.C-M-r: perl:selection:rot13
80
81=back
82
83=item option-popup (enabled by default)
84
85Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
86runtime.
87
88=item selection-popup (enabled by default)
89
90Binds a popup menu to Ctrl-Button3 that lets you convert the selection
91text into various other formats/action (such as uri unescaping, perl
92evalution, web-browser starting etc.), depending on content.
93
94=item searchable-scrollback<hotkey> (enabled by default)
95
96Adds regex search functionality to the scrollback buffer, triggered
97by a hotkey (default: C<M-s>). While in search mode, normal terminal
98input/output is suspended and a regex is displayed at the bottom of the
99screen.
100
101Inputting characters appends them to the regex and continues incremental
102search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
103search upwards/downwards in the scrollback buffer, C<End> jumps to the
104bottom. C<Escape> leaves search mode and returns to the point where search
105was started, while C<Enter> or C<Return> stay at the current position and
106additionally stores the first match in the current line into the primary
107selection.
108
109=item selection-autotransform
110
111This selection allows you to do automatic transforms on a selection
112whenever a selection is made.
113
114It works by specifying perl snippets (most useful is a single C<s///>
115operator) that modify C<$_> as resources:
116
117 URxvt.selection-autotransform.0: transform
118 URxvt.selection-autotransform.1: transform
119 ...
120
121For example, the following will transform selections of the form
122C<filename:number>, often seen in compiler messages, into C<vi +$filename
123$word>:
124
125 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
126
127And this example matches the same,but replaces it with vi-commands you can
128paste directly into your (vi :) editor:
129
130 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
131
132Of course, this can be modified to suit your needs and your editor :)
133
134To expand the example above to typical perl error messages ("XXX at
135FILENAME line YYY."), you need a slightly more elaborate solution:
136
137 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
138 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
139
140The first line tells the selection code to treat the unchanging part of
141every error message as a selection pattern, and the second line transforms
142the message into vi commands to load the file.
143
144=item mark-urls
145
146Uses per-line display filtering (C<on_line_update>) to underline urls and
147make them clickable. When middle-clicked, the program specified in the
148resource C<urlLauncher> (default C<x-www-browser>) will be started with
149the URL as first argument.
150
151=item block-graphics-to-ascii
152
153A not very useful example of filtering all text output to the terminal,
154by replacing all line-drawing characters (U+2500 .. U+259F) by a
155similar-looking ascii character.
156
157=item digital-clock
158
159Displays a digital clock using the built-in overlay.
160
161=item example-refresh-hooks
162
163Displays a very simple digital clock in the upper right corner of the
164window. Illustrates overwriting the refresh callbacks to create your own
165overlays or changes.
166
167=item selection-pastebin
168
169This is a little rarely useful extension that Uploads the selection as
170textfile to a remote site (or does other things). (The implementation is
171not currently secure for use in a multiuser environment as it writes to
172F</tmp> directly.).
173
174It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
175i.e.
176
177 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
178
179Pressing this combination runs a command with C<%> replaced by the name of
180the textfile. This command can be set via a resource:
181
182 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
183
184And the default is likely not useful to anybody but the few people around
185here :)
186
187The name of the textfile is the hex encoded md5 sum of the selection, so
188the same content should lead to the same filename.
189
190After a successful upload the selection will be replaced by the text given
191in the C<selection-pastebin-url> resource (again, the % is the placeholder
192for the filename):
193
194 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

831Dynamically enable the given hooks (named without the C<on_> prefix) for
832this extension, replacing any previous hook. This is useful when you want
833to overwrite time-critical hooks only temporarily.

836method of the C<urxvt::term> class.
