45 49which can be bound to a key and invoked by the user. An extension can

47 51described below. Similarly to builtin resources, extension resources
48(More) intelligent selection. This extension tries to be more intelligent 52can also be specified on the command line as long options (with C<.>
49when the user extends selections (double-click and further clicks). Right 53replaced by C<->), in which case the corresponding extension is loaded
50now, it tries to select words, urls and complete shell-quoted 54automatically. For this to work the extension B<must> define META
51arguments, which is very convenient, too, if your F<ls> supports 55comments for its resources.
52C<--quoting-style=shell>.
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.
74
75This extension also offers following bindable keyboard commands:
76
77=over 4
78
79=item rot13
80
81Rot-13 the selection when activated. Used via keyboard trigger:
82
83 URxvt.keysym.C-M-r: perl:selection:rot13
84
85=back
86
87=item option-popup (enabled by default)
88
89Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
90runtime.
91
92=item selection-popup (enabled by default)
93
94Binds a popup menu to Ctrl-Button3 that lets you convert the selection
95text into various other formats/action (such as uri unescaping, perl
96evaluation, web-browser starting etc.), depending on content.
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
112 push @{ $self->{term}{selection_popup_hook} }, sub {
113 /a/ ? ("a to be" => sub { s/a/b/g }
114 : ()
115 };
116
117=item searchable-scrollback<hotkey> (enabled by default)
118
119Adds regex search functionality to the scrollback buffer, triggered
120by a hotkey (default: C<M-s>). While in search mode, normal terminal
121input/output is suspended and a regex is displayed at the bottom of the
122screen.
123
124Inputting characters appends them to the regex and continues incremental
125search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
126search upwards/downwards in the scrollback buffer, C<End> jumps to the
127bottom. C<Escape> leaves search mode and returns to the point where search
128was started, while C<Enter> or C<Return> stay at the current position and
129additionally stores the first match in the current line into the primary
130selection.
131
132=item readline (enabled by default)
133
134A support package that tries to make editing with readline easier. At the
135moment, it reacts to clicking with the left mouse button by trying to
136move the text cursor to this position. It does so by generating as many
137cursor-left or cursor-right keypresses as required (the this only works
138for programs that correctly support wide characters).
139
140To avoid too many false positives, this is only done when:
141
142=over 4
143
144=item - the mouse is on the same (multi-row-) line as the text cursor.
145
146=item - the primary screen is currently being displayed.
147
148=item - the text cursor is visible.
149
150=back
151
152The normal selection mechanism isn't disabled, so quick successive clicks
153might interfere with selection creation in harmless ways.
154
155=item selection-autotransform
156
157This selection allows you to do automatic transforms on a selection
158whenever a selection is made.
159
160It works by specifying perl snippets (most useful is a single C<s///>
161operator) that modify C<$_> as resources:
162
163 URxvt.selection-autotransform.0: transform
164 URxvt.selection-autotransform.1: transform
165 ...
166
167For example, the following will transform selections of the form
168C<filename:number>, often seen in compiler messages, into C<vi +$filename
169$word>:
170
171 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
172
173And this example matches the same,but replaces it with vi-commands you can
174paste directly into your (vi :) editor:
175
176 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
177
178Of course, this can be modified to suit your needs and your editor :)
179
180To expand the example above to typical perl error messages ("XXX at
181FILENAME line YYY."), you need a slightly more elaborate solution:
182
183 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
184 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
185
186The first line tells the selection code to treat the unchanging part of
187every error message as a selection pattern, and the second line transforms
188the message into vi commands to load the file.
189
190=item tabbed
191
192This transforms the terminal into a tabbar with additional terminals, that
193is, it implements what is commonly refered to as "tabbed terminal". The topmost line
194displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
195button per tab.
196
197Clicking a button will activate that tab. Pressing B<Shift-Left> and
198B<Shift-Right> will switch to the tab left or right of the current one,
199while B<Shift-Down> creates a new tab.
200
201=item mark-urls
202
203Uses per-line display filtering (C<on_line_update>) to underline urls and
204make them clickable. When middle-clicked, the program specified in the
205resource C<urlLauncher> (default C<x-www-browser>) will be started with
206the URL as first argument.
207
208=item automove-background
209
210This is basically a one-line extension that dynamically changes the background pixmap offset
211to the window position, in effect creating the same effect as pseudo transparency with
212a custom pixmap. No scaling is supported in this mode. Exmaple:
213
214 @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
215
216=item block-graphics-to-ascii
217
218A not very useful example of filtering all text output to the terminal,
219by replacing all line-drawing characters (U+2500 .. U+259F) by a
220similar-looking ascii character.
221
222=item digital-clock
223
224Displays a digital clock using the built-in overlay.
225
226=item example-refresh-hooks
227
228Displays a very simple digital clock in the upper right corner of the
229window. Illustrates overwriting the refresh callbacks to create your own
230overlays or changes.
231
232=item selection-pastebin
233
234This is a little rarely useful extension that Uploads the selection as
235textfile to a remote site (or does other things). (The implementation is
236not currently secure for use in a multiuser environment as it writes to
237F</tmp> directly.).
238
239It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
240i.e.
241
242 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
243
244Pressing this combination runs a command with C<%> replaced by the name of
245the textfile. This command can be set via a resource:
246
247 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
248
249And the default is likely not useful to anybody but the few people around
250here :)
251
252The name of the textfile is the hex encoded md5 sum of the selection, so
253the same content should lead to the same filename.
254
255After a successful upload the selection will be replaced by the text given
256in the C<selection-pastebin-url> resource (again, the % is the placeholder
257for the filename):

1335Extensions that define extra resources also need to call this method
1336to access their values.
1337
1338If the method is called on an extension object (basically, from an
1339extension), then the special prefix C<%.> will be replaced by the name of
1340the extension and a dot, and the lone string C<%> will be replaced by the
1341extension name itself. This makes it possible to code extensions so you
1342can rename them and get a new set of resources without having to change
1343the actual code.
