36 when the user extends selections (double-click). Right now, it tries 36 intelligent when the user extends selections (double-click and
37 to select urls and complete shell-quoted arguments, which is very 37 further clicks). Right now, it tries to select words, urls and
38 complete shell-quoted arguments, which is very convenient, too, if
38 convenient, too, if your ls supports "--quoting-style=shell". 39 your ls supports "--quoting-style=shell".
39 40
40 It also offers the following bindable event: 41 A double-click usually selects the word under the cursor, further
42 clicks will enlarge the selection.
43
44 The selection works by trying to match a number of regexes and
45 displaying them in increasing order of length. You can add your own
46 regexes by specifying resources of the form:
47
48 URxvt.selection.pattern-0: perl-regex
49 URxvt.selection.pattern-1: perl-regex
50 ...
51
52 The index number (0, 1...) must not have any holes, and each regex
53 must contain at least one pair of capturing parentheses, which will
54 be used for the match. For example, the followign adds a regex that
55 matches everything between two vertical bars:
56
57 URxvt.selection.pattern-0: \\|([^|]+)\\|
58
59 You can look at the source of the selection extension to see more
60 interesting uses, such as parsing a line from beginning to end.
61
62 This extension also offers following bindable keyboard commands:

56 Displays a digital clock using the built-in overlay. 80 reference onto "@{ $term-"{selection_popup_hook} }>, that is called
81 whenever the popup is displayed.
82
83 It's sole argument is the popup menu, which can be modified. The
84 selection is in $_, which can be used to decide wether to add
85 something or not. It should either return nothing or a string and a
86 code reference. The string will be used as button text and the code
87 reference will be called when the button gets activated and should
88 transform $_.
89
90 The following will add an entry "a to b" that transforms all "a"s in
91 the selection to "b"s, but only if the selection currently contains
92 any "a"s:
93
94 push @{ $self->{term}{selection_popup_hook} }, sub {
95 /a/ ? ("a to be" => sub { s/a/b/g }
96 : ()
97 };
98
99 searchable-scrollback<hotkey> (enabled by default)
100 Adds regex search functionality to the scrollback buffer, triggered
101 by a hotkey (default: "M-s"). While in search mode, normal terminal
102 input/output is suspended and a regex is displayed at the bottom of
103 the screen.
104
105 Inputting characters appends them to the regex and continues
106 incremental search. "BackSpace" removes a character from the regex,
107 "Up" and "Down" search upwards/downwards in the scrollback buffer,
108 "End" jumps to the bottom. "Escape" leaves search mode and returns
109 to the point where search was started, while "Enter" or "Return"
110 stay at the current position and additionally stores the first match
111 in the current line into the primary selection.
112
113 selection-autotransform
114 This selection allows you to do automatic transforms on a selection
115 whenever a selection is made.
116
117 It works by specifying perl snippets (most useful is a single "s///"
118 operator) that modify $_ as resources:
119
120 URxvt.selection-autotransform.0: transform
121 URxvt.selection-autotransform.1: transform
122 ...
123
124 For example, the following will transform selections of the form
125 "filename:number", often seen in compiler messages, into "vi
126 +$filename $word":
127
128 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
129
130 And this example matches the same,but replaces it with vi-commands
131 you can paste directly into your (vi :) editor:
132
133 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
134
135 Of course, this can be modified to suit your needs and your editor
136 :)
137
138 To expand the example above to typical perl error messages ("XXX at
139 FILENAME line YYY."), you need a slightly more elaborate solution:
140
141 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
142 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
143
144 The first line tells the selection code to treat the unchanging part
145 of every error message as a selection pattern, and the second line
146 transforms the message into vi commands to load the file.

60 urls. 150 and make them clickable. When middle-clicked, the program specified
151 in the resource "urlLauncher" (default "x-www-browser") will be
152 started with the URL as first argument.
153
154 automove-background
155 This is basically a one-line extension that dynamically changes the
156 background pixmap offset to the window position, in effect creating
157 the same effect as pseudo transparency with a custom pixmap. No
158 scaling is supported in this mode. Exmaple:
159
160 rxvt -pixmap background.xpm -pe automove-background

70 your own overlays or changes. 173 your own overlays or changes.
71 174
175 selection-pastebin
176 This is a little rarely useful extension that Uploads the selection
177 as textfile to a remote site (or does other things). (The
178 implementation is not currently secure for use in a multiuser
179 environment as it writes to /tmp directly.).
180
181 It listens to the "selection-pastebin:remote-pastebin" keyboard
182 command, i.e.
183
184 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
185
186 Pressing this combination runs a command with "%" replaced by the
187 name of the textfile. This command can be set via a resource:
188
189 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
190
191 And the default is likely not useful to anybody but the few people
192 around here :)
193
194 The name of the textfile is the hex encoded md5 sum of the
195 selection, so the same content should lead to the same filename.
196
197 After a successful upload the selection will be replaced by the text
198 given in the "selection-pastebin-url" resource (again, the % is the
199 placeholder for the filename):
200
201 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

233 Extension Objects
234 Very perl extension is a perl class. A separate perl object is created
235 for each terminal and each extension and passed as the first parameter
236 to hooks. So extensions can use their $self object without having to
237 think about other extensions, with the exception of methods and members
238 that begin with an underscore character "_": these are reserved for
239 internal use.
240
241 Although it isn't a "urxvt::term" object, you can call all methods of
242 the "urxvt::term" class on this object.
243
244 It has the following methods and data members:
245
246 $urxvt_term = $self->{term}
247 Returns the "urxvt::term" object associated with this instance of
248 the extension. This member *must not* be changed in any way.
249
250 $self->enable ($hook_name => $cb, [$hook_name => $cb..])
251 Dynamically enable the given hooks (named without the "on_" prefix)
252 for this extension, replacing any previous hook. This is useful when
253 you want to overwrite time-critical hooks only temporarily.
254
255 $self->disable ($hook_name[, $hook_name..])
256 Dynamically disable the given hooks.

107 its not a real "urxvt::term" object. Instead, the real "urxvt::term"
108 object that is shared between all packages is stored in the "term"
109 member. It is, however, blessed intot he package of the extension
110 script, so for all practical purposes you can treat an extension script
111 as a class.

527 Creates a new terminal, very similar as if you had started it with
528 system "$rxvtname, arg...". $envhashref must be a reference to a
529 %ENV-like hash which defines the environment of the new terminal.
530
531 Croaks (and probably outputs an error message) if the new instance
532 couldn't be created. Returns "undef" if the new instance didn't
533 initialise perl, and the terminal object otherwise. The "init" and

541 $term->exec_async ($cmd[, @args])
542 Works like the combination of the "fork"/"exec" builtins, which
543 executes ("starts") programs in the background. This function takes
544 care of setting the user environment before exec'ing the command
545 (e.g. "PATH") and should be preferred over explicit calls to "exec"
