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
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.

54 78
55 digital-clock 79 searchable-scrollback<hotkey> (enabled by default)
56 Displays a digital clock using the built-in overlay. 80 Adds regex search functionality to the scrollback buffer, triggered
81 by a hotkey (default: "M-s"). While in search mode, normal terminal
82 input/output is suspended and a regex is displayed at the bottom of
83 the screen.
84
85 Inputting characters appends them to the regex and continues
86 incremental search. "BackSpace" removes a character from the regex,
87 "Up" and "Down" search upwards/downwards in the scrollback buffer,
88 "End" jumps to the bottom. "Escape" leaves search mode and returns
89 to the point where search was started, while "Enter" or "Return"
90 stay at the current position and additionally stores the first match
91 in the current line into the primary selection.
92
93 selection-autotransform
94 This selection allows you to do automatic transforms on a selection
95 whenever a selection is made.
96
97 It works by specifying perl snippets (most useful is a single "s///"
98 operator) that modify $_ as resources:
99
100 URxvt.selection-autotransform.0: transform
101 URxvt.selection-autotransform.1: transform
102 ...
103
104 For example, the following will transform selections of the form
105 "filename:number", often seen in compiler messages, into "vi
106 +$filename $word":
107
108 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
109
110 And this example matches the same,but replaces it with vi-commands
111 you can paste directly into your (vi :) editor:
112
113 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
114
115 Of course, this can be modified to suit your needs and your editor
116 :)
117
118 To expand the example above to typical perl error messages ("XXX at
119 FILENAME line YYY."), you need a slightly more elaborate solution:
120
121 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
122 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
123
124 The first line tells the selection code to treat the unchanging part
125 of every error message as a selection pattern, and the second line
126 transforms the message into vi commands to load the file.

177 Extension Objects
178 Very perl extension is a perl class. A separate perl object is created
179 for each terminal and each extension and passed as the first parameter
180 to hooks. So extensions can use their $self object without having to
181 think about other extensions, with the exception of methods and members
182 that begin with an underscore character "_": these are reserved for
183 internal use.
184
185 Although it isn't a "urxvt::term" object, you can call all methods of
186 the "urxvt::term" class on this object.
187
188 It has the following methods and data members:
189
190 $urxvt_term = $self->{term}
191 Returns the "urxvt::term" object associated with this instance of
192 the extension. This member *must not* be changed in any way.
193
194 $self->enable ($hook_name => $cb, [$hook_name => $cb..])
195 Dynamically enable the given hooks (named without the "on_" prefix)
196 for this extension, replacing any previous hook. This is useful when
197 you want to overwrite time-critical hooks only temporarily.
198
199 $self->disable ($hook_name[, $hook_name..])
200 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.
