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 using so called META comments,
47arguments, which is very convenient, too, if your F<ls> supports 51described below. Similarly to builtin resources, extension resources
48C<--quoting-style=shell>. 52can also be specified on the command line as long options (with C<.>
49 53replaced by C<->), in which case the corresponding extension is loaded
50A double-click usually selects the word under the cursor, further clicks 54automatically. For this to work the extension B<must> define META
51will enlarge the selection. 55comments for its resources.
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
169Uploads the selection as textfile to a remote site.
170
171 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
172
173To set the command to upload the file set this resource:
174
175 URxvt.selection-pastebin-cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
176
177The % is the placeholder for the textfile. The name of the textfile is the hex encoded
178md5 sum of the selection.
179After an successful upload the selection will be replaced by the following url
180(the % is the placeholder for the filename):

1321Extensions that define extra resources also need to call this method
1322to access their values.
1323
1324If the method is called on an extension object (basically, from an
1325extension), then the special prefix C<%.> will be replaced by the name of
1326the extension and a dot, and the lone string C<%> will be replaced by the
1327extension name itself. This makes it possible to code extensions so you
1328can rename them and get a new set of resources without having to change
1329the actual code.

1356To add default bindings for actions, an extension should call C<<

1358in the C<init> hook allows users to override or remove the binding
1359again.
