35 (More) intelligent selection. This extension tries to be more 35 (More) intelligent selection. This extension tries to be more
36 intelligent when the user extends selections (double-click). Right 36 intelligent when the user extends selections (double-click and
37 now, it tries to select urls and complete shell-quoted arguments, 37 further clicks). Right now, it tries to select words, urls and
38 which is very convenient, too, if your ls supports 38 complete shell-quoted arguments, which is very convenient, too, if
39 "--quoting-style=shell". 39 your ls supports "--quoting-style=shell".
40 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 selection text into various other formats/action (such as uri 75 selection text into various other formats/action (such as uri
55 unescaping, perl evalution, web-browser starting etc.), depending on 76 unescaping, perl evalution, web-browser starting etc.), depending on
56 content. 77 content.
57 78
79 Other extensions can extend this popup menu by pushing a code
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 };

60 by a hotkey (default: "M-s"). When in search mode, normal terminal 101 by a hotkey (default: "M-s"). While in search mode, normal terminal
61 input/output is suspended. 102 input/output is suspended and a regex is displayed at the bottom of
103 the screen.
62 104
63 "/" starts an incremental regex search, "n" searches further, "p" or 105 Inputting characters appends them to the regex and continues
64 "N" jump to the previous match, "G" jumps to the bottom and clears 106 incremental search. "BackSpace" removes a character from the regex,
65 the history, "enter" leaves search mode at the current position and 107 "Up" and "Down" search upwards/downwards in the scrollback buffer,
66 "escape" returns to the original position. 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.
67 112
68 digital-clock 113 selection-autotransform
69 Displays a digital clock using the built-in overlay. 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.

73 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

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/%
