44(More) intelligent selection. This extension tries to be more intelligent 48Extensions may add additional resources and C<actions>, i.e., methods
45when the user extends selections (double-click and further clicks). Right 49which can be bound to a key and invoked by the user. An extension can
46now, it tries to select words, urls and complete shell-quoted 50define the resources it support and also default bindings for one or
47arguments, which is very convenient, too, if your F<ls> supports 51more actions it provides using so called META comments, described
48C<--quoting-style=shell>. 52below. Similarly to builtin resources, extension resources can also be
49 53specified on the command line as long options (with C<.> replaced by
50A double-click usually selects the word under the cursor, further clicks 54C<->), in which case the corresponding extension is loaded
51will enlarge the selection. 55automatically. For this to work the extension B<must> define META
52 56comments for its resources.
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=item remote-pastebin
82
83Upload the selection as textfile to a remote site.
84
85 URxvt.keysym.C-M-e: perl:selection:remote-pastebin
86
87To set the command to upload the file set this resource:
88
89 URxvt.selection-pastebin-cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
90
91The % is the placeholder for the textfile. The name of the textfile is the hex encoded
92md5 sum of the selection.
93After an successful upload the selection will be replaced by the following url
94(the % is the placeholder for the filename):
95
96 URxvt.selection-pastebin-url: http://www.ta-sa.org/files/txt/%
97
98=back
99
100=item option-popup (enabled by default)
101
102Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
103runtime.
104
105=item selection-popup (enabled by default)
106
107Binds a popup menu to Ctrl-Button3 that lets you convert the selection
108text into various other formats/action (such as uri unescaping, perl
109evalution, web-browser starting etc.), depending on content.
110
111=item searchable-scrollback<hotkey> (enabled by default)
112
113Adds regex search functionality to the scrollback buffer, triggered
114by a hotkey (default: C<M-s>). While in search mode, normal terminal
115input/output is suspended and a regex is displayed at the bottom of the
116screen.
117
118Inputting characters appends them to the regex and continues incremental
119search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
120search upwards/downwards in the scrollback buffer, C<End> jumps to the
121bottom. C<Escape> leaves search mode and returns to the point where search
122was started, while C<Enter> or C<Return> stay at the current position and
123additionally stores the first match in the current line into the primary
124selection.
125
126=item selection-autotransform
127
128This selection allows you to do automatic transforms on a selection
129whenever a selection is made.
130
131It works by specifying perl snippets (most useful is a single C<s///>
132operator) that modify C<$_> as resources:
133
134 URxvt.selection-autotransform.0: transform
135 URxvt.selection-autotransform.1: transform
136 ...
137
138For example, the following will transform selections of the form
139C<filename:number>, often seen in compiler messages, into C<vi +$filename
140$word>:
141
142 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
143
144And this example matches the same,but replaces it with vi-commands you can
145paste directly into your (vi :) editor:
146
147 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
148
149Of course, this can be modified to suit your needs and your editor :)
150
151To expand the example above to typical perl error messages ("XXX at
152FILENAME line YYY."), you need a slightly more elaborate solution:
153
154 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
155 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
156
157The first line tells the selection code to treat the unchanging part of
158every error message as a selection pattern, and the second line transforms
159the message into vi commands to load the file.
160
161=item mark-urls
162
163Uses per-line display filtering (C<on_line_update>) to underline urls and
164make them clickable. When middle-clicked, the program specified in the
165resource C<urlLauncher> (default C<x-www-browser>) will be started with
166the URL as first argument.
167
168=item block-graphics-to-ascii
169
170A not very useful example of filtering all text output to the terminal,
171by replacing all line-drawing characters (U+2500 .. U+259F) by a
172similar-looking ascii character.
173
174=item digital-clock
175
176Displays a digital clock using the built-in overlay.
177
178=item example-refresh-hooks
179
180Displays a very simple digital clock in the upper right corner of the
181window. Illustrates overwriting the refresh callbacks to create your own
182overlays or changes.

1319Extensions that define extra resources also need to call this method
1320to access their values.
1321
1322If the method is called on an extension object (basically, from an
1323extension), then the special prefix C<%.> will be replaced by the name of
1324the extension and a dot, and the lone string C<%> will be replaced by the
1325extension name itself. This makes it possible to code extensions so you
1326can rename them and get a new set of resources without having to change
1327the actual code.

1354To add default bindings for an extension, the extension should call C<<
1355->bind_action >> on it's C<init> hook for every such binding. Doing it
1356in the C<init> hook allows users the override or remove the the binding
1357again.
