44(More) intelligent selection. This extension tries to be more intelligent 48Extensions may add additional resources and C<actions>, i.e., methods
45when the user extends selections (double-click and further clicks). Right 49which can be bound to a key and invoked by the user. An extension can
46now, it tries to select words, urls and complete shell-quoted 50define the resources it support using so called META comments,
47arguments, which is very convenient, too, if your F<ls> supports 51described below. Similarly to builtin resources, extension resources
48C<--quoting-style=shell>. 52can also be specified on the command line as long options (with C<.>
49 53replaced by C<->), in which case the corresponding extension is loaded
50A double-click usually selects the word under the cursor, further clicks 54automatically. For this to work the extension B<must> define META
51will enlarge the selection. 55comments for its resources.
52
53The selection works by trying to match a number of regexes and displaying
54them in increasing order of length. You can add your own regexes by
55specifying resources of the form:
56
57 URxvt.selection.pattern-0: perl-regex
58 URxvt.selection.pattern-1: perl-regex
59 ...
60
61The index number (0, 1...) must not have any holes, and each regex must
62contain at least one pair of capturing parentheses, which will be used for
63the match. For example, the followign adds a regex that matches everything
64between two vertical bars:
65
66 URxvt.selection.pattern-0: \\|([^|]+)\\|
67
68You can look at the source of the selection extension to see more
69interesting uses, such as parsing a line from beginning to end.
70
71This extension also offers following bindable keyboard commands:
72
73=over 4
74
75=item rot13
76
77Rot-13 the selection when activated. Used via keyboard trigger:
78
79 URxvt.keysym.C-M-r: perl:selection:rot13
80
81=back
82
83=item option-popup (enabled by default)
84
85Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
86runtime.
87
88=item selection-popup (enabled by default)
89
90Binds a popup menu to Ctrl-Button3 that lets you convert the selection
91text into various other formats/action (such as uri unescaping, perl
92evalution, web-browser starting etc.), depending on content.
93
94=item searchable-scrollback<hotkey> (enabled by default)
95
96Adds regex search functionality to the scrollback buffer, triggered
97by a hotkey (default: C<M-s>). While in search mode, normal terminal
98input/output is suspended and a regex is displayed at the bottom of the
99screen.
100
101Inputting characters appends them to the regex and continues incremental
102search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
103search upwards/downwards in the scrollback buffer, C<End> jumps to the
104bottom. C<Escape> leaves search mode and returns to the point where search
105was started, while C<Enter> or C<Return> stay at the current position and
106additionally stores the first match in the current line into the primary
107selection.
108
109=item selection-autotransform
110
111This selection allows you to do automatic transforms on a selection
112whenever a selection is made.
113
114It works by specifying perl snippets (most useful is a single C<s///>
115operator) that modify C<$_> as resources:
116
117 URxvt.selection-autotransform.0: transform
118 URxvt.selection-autotransform.1: transform
119 ...
120
121For example, the following will transform selections of the form
122C<filename:number>, often seen in compiler messages, into C<vi +$filename
123$word>:
124
125 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
126
127And this example matches the same,but replaces it with vi-commands you can
128paste directly into your (vi :) editor:
129
130 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
131
132Of course, this can be modified to suit your needs and your editor :)
133
134To expand the example above to typical perl error messages ("XXX at
135FILENAME line YYY."), you need a slightly more elaborate solution:
136
137 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
138 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
139
140The first line tells the selection code to treat the unchanging part of
141every error message as a selection pattern, and the second line transforms
142the message into vi commands to load the file.
143
144=item mark-urls
145
146Uses per-line display filtering (C<on_line_update>) to underline urls and
147make them clickable. When middle-clicked, the program specified in the
148resource C<urlLauncher> (default C<x-www-browser>) will be started with
149the URL as first argument.
150
151=item block-graphics-to-ascii
152
153A not very useful example of filtering all text output to the terminal,
154by replacing all line-drawing characters (U+2500 .. U+259F) by a
155similar-looking ascii character.
156
157=item digital-clock
158
159Displays a digital clock using the built-in overlay.
160
161=item example-refresh-hooks
162
163Displays a very simple digital clock in the upper right corner of the
164window. Illustrates overwriting the refresh callbacks to create your own
165overlays or changes.
166
167=item selection-pastebin
168
169This is a little rarely useful extension that Uploads the selection as
170textfile to a remote site (or does other things). (The implementation is
171not currently secure for use in a multiuser environment as it writes to
172F</tmp> directly.).
173
174It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
175i.e.
176
177 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
178
179Pressing this combination runs a command with C<%> replaced by the name of
180the textfile. This command can be set via a resource:
181
182 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
183
184And the default is likely not useful to anybody but the few people around
185here :)
186
187The name of the textfile is the hex encoded md5 sum of the selection, so
188the same content should lead to the same filename.
189
190After a successful upload the selection will be replaced by the text given
191in the C<selection-pastebin-url> resource (again, the % is the placeholder
192for the filename):
193
194 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%

246C<urxvt::term> class on this object. 112C<urxvt::term> class on this object.
247 113
248It has the following methods and data members: 114Additional methods only supported for extension objects are described in
115the C<urxvt::extension> section below.
249 116
117=head2 META comments
118
119Rxvt-unicode recognizes special meta comments in extensions that define
120different types of metadata. These comments are scanned whenever a
121terminal is created and are typically used to autoload extensions when
122their resources or command line parameters are used.
123
124Currently, it recognises these comments below. Individual components are
125separated by colons (C<:>), and should not contain colons themselves -
126there is also currently no escaping mechanism provided for this.

255extension. This member I<must not> be changed in any way. 133C<name> is the resource name, C<type> is the resource type, C<boolean>
134or C<string>, and C<desc> is the resource description.
256 135
257=item $self->enable ($hook_name => $cb, [$hook_name => $cb..]) 136The extension will be autoloaded when this resource is specified or used
137as a command line parameter.
258 138
259Dynamically enable the given hooks (named without the C<on_> prefix) for 139Example: matcher provides the C<matcher.launcher> resource by having this
260this extension, replacing any previous hook. This is useful when you want 140comment:
261to overwrite time-critical hooks only temporarily.
262 141
263=item $self->disable ($hook_name[, $hook_name..]) 142 #:META:RESOURCE:%.launcher:string:default launcher command
264 143
265Dynamically disable the given hooks. 144Example: load this extension when the C<-tr> command line option or
145resource name is used.
146
147 #:META:RESOURCE:tr:boolean:set root pixmap as background
148
149=item #:META:OSC:number:desc
150
151The OSC comment specifies an OSC sequence, where C<number> is the
152numerical OSC code and C<desc> is a short description that is currently
153unused.
154
155This will cause the extension to be autoloaded when the OSC sequence is
156used for the first time.
157
158Note that autoloading carries some extra responsibilities with it:
159although the terminal cannot really protect itself against malicious
160sources of command sequences, therefore relying on the programs running
161I<inside> to sanitize data that they output, it is very common for
162programs to emit command sequences from untrusted sources.
163
164While this means that extensions should, as a defense-in-depth mechanism,
165always consider whether OSC sequences are safe, autoloading automatically
166exposes any autoloaded extension in all terminal windows, so extra care
167should be taken.
168
169Example: the background extension registers OSC C<20> like this:
170
171 #:META:OSC:20:change/query background image
172
173=item #:META:OSC_PERL:prefix:desc
174
175The same as the OSC comment, but for the Perl OSC sequence (C<777>). The
176C<prefix> should be unique among extensions, of course, which is most
177easily arranged by using the extension name, although this is not
178required.
179
180Example: the overlay-osc extension registers its Perl OSC like this:
181
182 #:META:OSC_PERL:overlay:man overlay-osc
