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
94Other extensions can extend this popup menu by pushing a code reference onto
95C<@urxvt::ext::selection_popup::hook>, that is called whenever the popup is displayed.
96
97It's sole argument is the popup menu, which can be modified. The selection
98is in C<$_>, which can be used to decide wether to add something or not.
99It should either return nothing or a string and a code reference. The
100string will be used as button text and the code reference will be called
101when the button gets activated and should transform C<$_>.
102
103The following will add an entry C<a to b> that transforms all C<a>s in
104the selection to C<b>s, but only if the selection currently contains any
105C<a>s:
106
107 push urxvt::ext::selection_popup::hook, sub {
108 /a/ ? ("a to be" => sub { s/a/b/g }
109 : ()
110 };
111
112=item searchable-scrollback<hotkey> (enabled by default)
113
114Adds regex search functionality to the scrollback buffer, triggered
115by a hotkey (default: C<M-s>). While in search mode, normal terminal
116input/output is suspended and a regex is displayed at the bottom of the
117screen.
118
119Inputting characters appends them to the regex and continues incremental
120search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
121search upwards/downwards in the scrollback buffer, C<End> jumps to the
122bottom. C<Escape> leaves search mode and returns to the point where search
123was started, while C<Enter> or C<Return> stay at the current position and
124additionally stores the first match in the current line into the primary
125selection.
126
127=item selection-autotransform
128
129This selection allows you to do automatic transforms on a selection
130whenever a selection is made.
131
132It works by specifying perl snippets (most useful is a single C<s///>
133operator) that modify C<$_> as resources:
134
135 URxvt.selection-autotransform.0: transform
136 URxvt.selection-autotransform.1: transform
137 ...
138
139For example, the following will transform selections of the form
140C<filename:number>, often seen in compiler messages, into C<vi +$filename
141$word>:
142
143 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
144
145And this example matches the same,but replaces it with vi-commands you can
146paste directly into your (vi :) editor:
147
148 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
149
150Of course, this can be modified to suit your needs and your editor :)
151
152To expand the example above to typical perl error messages ("XXX at
153FILENAME line YYY."), you need a slightly more elaborate solution:
154
155 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
156 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
157
158The first line tells the selection code to treat the unchanging part of
159every error message as a selection pattern, and the second line transforms
160the message into vi commands to load the file.
161
162=item mark-urls
163
164Uses per-line display filtering (C<on_line_update>) to underline urls and
165make them clickable. When middle-clicked, the program specified in the
166resource C<urlLauncher> (default C<x-www-browser>) will be started with
167the URL as first argument.
168
169=item automove-background
170
171This is basically a one-line extension that dynamically changes the background pixmap offset
172to the window position, in effect creating the same effect as pseudo transparency with
173a custom pixmap. No scaling is supported in this mode. Exmaple:
174
175 @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
176
177=item block-graphics-to-ascii
178
179A not very useful example of filtering all text output to the terminal,
180by replacing all line-drawing characters (U+2500 .. U+259F) by a
181similar-looking ascii character.
182
183=item digital-clock
184
185Displays a digital clock using the built-in overlay.
186
187=item example-refresh-hooks
188
189Displays a very simple digital clock in the upper right corner of the
190window. Illustrates overwriting the refresh callbacks to create your own
191overlays or changes.
192
193=item selection-pastebin
194
195This is a little rarely useful extension that Uploads the selection as
196textfile to a remote site (or does other things). (The implementation is
197not currently secure for use in a multiuser environment as it writes to
198F</tmp> directly.).
199
200It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
201i.e.
202
203 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
204
205Pressing this combination runs a command with C<%> replaced by the name of
206the textfile. This command can be set via a resource:
207
208 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
209
210And the default is likely not useful to anybody but the few people around
211here :)
212
213The name of the textfile is the hex encoded md5 sum of the selection, so
214the same content should lead to the same filename.
215
216After a successful upload the selection will be replaced by the text given
217in the C<selection-pastebin-url> resource (again, the % is the placeholder
218for the filename):
219
220 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
