35 Intelligent selection. This extension tries to be more intelligent 35 (More) intelligent selection. This extension tries to be more
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.
61
40 It also offers the following bindable event: 62 This extension also offers the following bindable keyboard command:

49 options at runtime. 71 options at runtime.
50 72
51 digital-clock 73 selection-popup (enabled by default)
52 Displays a digital clock using the built-in overlay. 74 Binds a popup menu to Ctrl-Button3 that lets you convert the
75 selection text into various other formats/action (such as uri
76 unescaping, perl evalution, web-browser starting etc.), depending on
77 content.
78
79 searchable-scrollback<hotkey> (enabled by default)
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 $word":
107
108 URxvt.selection-autotransform.0: s/^(\\S+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
109
110 And this example matches the same,but replaces it with vi-commands
111 you can paste directly into your (vi :) editor:
112
113 URxvt.selection-autotransform.0: s/^(S+):(d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
114
115 Of course, this can be modified to suit your needs and your editor
116 :)

167 Extension Objects
168 Very perl extension is a perl class. A separate perl object is created
169 for each terminal and each extension and passed as the first parameter
170 to hooks. So extensions can use their $self object without having to
171 think about other extensions, with the exception of methods and members
172 that begin with an underscore character "_": these are reserved for
173 internal use.
174
175 Although it isn't a "urxvt::term" object, you can call all methods of
176 the "urxvt::term" class on this object.
177
178 It has the following methods and data members:
179
180 $urxvt_term = $self->{term}
181 Returns the "urxvt::term" object associated with this instance of
182 the extension. This member *must not* be changed in any way.
183
184 $self->enable ($hook_name => $cb, [$hook_name => $cb..])
185 Dynamically enable the given hooks (named without the "on_" prefix)
186 for this extension, replacing any previous hook. This is useful when
187 you want to overwrite time-critical hooks only temporarily.
188
189 $self->disable ($hook_name[, $hook_name..])
190 Dynamically disable the given hooks.

101 The first argument passed to them is an object private to each terminal 196 The first argument passed to them is an extension oject as described in
102 and extension package. You can call all "urxvt::term" methods on it, but 197 the in the "Extension Objects" section.
103 its not a real "urxvt::term" object. Instead, the real "urxvt::term"
104 object that is shared between all packages is stored in the "term"
105 member. It is, however, blessed intot he package of the extension
106 script, so for all practical purposes you can treat an extension script
107 as a class.

503 Returns the X-Resource for the given pattern, excluding the program
504 or class name, i.e. "$term->x_resource ("boldFont")" should return
505 the same value as used by this instance of rxvt-unicode. Returns
506 "undef" if no resource with that pattern exists.

508 This method should only be called during the "on_start" hook, as

532 Tries to make a selection as set by "selection_beg" and
