52C<--quoting-style=shell>.
48 53
49It also offers the following bindable event: 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
72Another example: Programs I use often output "absolute path: " at the
73beginning of a line when they process multiple files. The following
74pattern matches the filename (note, there is a single space at the very
75end):
76
77 URxvt.selection.pattern-0: ^(/[^:]+):\
78
79You can look at the source of the selection extension to see more
80interesting uses, such as parsing a line from beginning to end.
81
82This extension also offers following bindable keyboard commands:

65 98
66=item digital-clock 99=item selection-popup (enabled by default)
67 100
68Displays a digital clock using the built-in overlay. 101Binds a popup menu to Ctrl-Button3 that lets you convert the selection
102text into various other formats/action (such as uri unescaping, perl
103evaluation, web-browser starting etc.), depending on content.
104
105Other extensions can extend this popup menu by pushing a code reference
106onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
107popup is displayed.
108
109It's sole argument is the popup menu, which can be modified. The selection
110is in C<$_>, which can be used to decide wether to add something or not.
111It should either return nothing or a string and a code reference. The
112string will be used as button text and the code reference will be called
113when the button gets activated and should transform C<$_>.
114
115The following will add an entry C<a to b> that transforms all C<a>s in
116the selection to C<b>s, but only if the selection currently contains any
117C<a>s:
118
119 push @{ $self->{term}{selection_popup_hook} }, sub {
120 /a/ ? ("a to be" => sub { s/a/b/g }
121 : ()
122 };
123
124=item searchable-scrollback<hotkey> (enabled by default)
125
126Adds regex search functionality to the scrollback buffer, triggered
127by a hotkey (default: C<M-s>). While in search mode, normal terminal
128input/output is suspended and a regex is displayed at the bottom of the
129screen.
130
131Inputting characters appends them to the regex and continues incremental
132search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
133search upwards/downwards in the scrollback buffer, C<End> jumps to the
134bottom. C<Escape> leaves search mode and returns to the point where search
135was started, while C<Enter> or C<Return> stay at the current position and
136additionally stores the first match in the current line into the primary
137selection.
138
139=item readline (enabled by default)
140
141A support package that tries to make editing with readline easier. At the
142moment, it reacts to clicking with the left mouse button by trying to
143move the text cursor to this position. It does so by generating as many
144cursor-left or cursor-right keypresses as required (the this only works
145for programs that correctly support wide characters).
146
147To avoid too many false positives, this is only done when:
148
149=over 4
150
151=item - the tty is in ICANON state.
152
153=item - the text cursor is visible.
154
155=item - the primary screen is currently being displayed.
156
157=item - the mouse is on the same (multi-row-) line as the text cursor.
158
159=back
160
161The normal selection mechanism isn't disabled, so quick successive clicks
162might interfere with selection creation in harmless ways.
163
164=item selection-autotransform
165
166This selection allows you to do automatic transforms on a selection
167whenever a selection is made.
168
169It works by specifying perl snippets (most useful is a single C<s///>
170operator) that modify C<$_> as resources:
171
172 URxvt.selection-autotransform.0: transform
173 URxvt.selection-autotransform.1: transform
174 ...
175
176For example, the following will transform selections of the form
177C<filename:number>, often seen in compiler messages, into C<vi +$filename
178$word>:
179
180 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
181
182And this example matches the same,but replaces it with vi-commands you can
183paste directly into your (vi :) editor:
184
185 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
186
187Of course, this can be modified to suit your needs and your editor :)
188
189To expand the example above to typical perl error messages ("XXX at
190FILENAME line YYY."), you need a slightly more elaborate solution:
191
192 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
193 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
194
195The first line tells the selection code to treat the unchanging part of
196every error message as a selection pattern, and the second line transforms
197the message into vi commands to load the file.
198
199=item tabbed
200
201This transforms the terminal into a tabbar with additional terminals, that
202is, it implements what is commonly refered to as "tabbed terminal". The topmost line
203displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
204button per tab.
205
206Clicking a button will activate that tab. Pressing B<Shift-Left> and
207B<Shift-Right> will switch to the tab left or right of the current one,
208while B<Shift-Down> creates a new tab.

70=item mark-urls 210=item mark-urls
71 211
72Uses per-line display filtering (C<on_line_update>) to underline urls. 212Uses per-line display filtering (C<on_line_update>) to underline urls and
213make them clickable. When middle-clicked, the program specified in the
214resource C<urlLauncher> (default C<x-www-browser>) will be started with
215the URL as first argument.
216
217=item automove-background
218
219This is basically a one-line extension that dynamically changes the background pixmap offset
220to the window position, in effect creating the same effect as pseudo transparency with
221a custom pixmap. No scaling is supported in this mode. Exmaple:

85 240
241=item selection-pastebin
242
243This is a little rarely useful extension that Uploads the selection as
244textfile to a remote site (or does other things). (The implementation is
245not currently secure for use in a multiuser environment as it writes to
246F</tmp> directly.).
247
248It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
249i.e.
250
251 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
252
253Pressing this combination runs a command with C<%> replaced by the name of
254the textfile. This command can be set via a resource:
255
256 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
257
258And the default is likely not useful to anybody but the few people around
259here :)
260
261The name of the textfile is the hex encoded md5 sum of the selection, so
262the same content should lead to the same filename.
263
264After a successful upload the selection will be replaced by the text given
265in the C<selection-pastebin-url> resource (again, the % is the placeholder
266for the filename):

310=head2 Extension Objects
311
312Very perl extension is a perl class. A separate perl object is created
313for each terminal and each extension and passed as the first parameter to
314hooks. So extensions can use their C<$self> object without having to think
315about other extensions, with the exception of methods and members that
316begin with an underscore character C<_>: these are reserved for internal
317use.
318
319Although it isn't a C<urxvt::term> object, you can call all methods of the
320C<urxvt::term> class on this object.
