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

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
94Other extensions can extend this popup menu by pushing a code reference onto
95C<@urxvt::ext::selection_popup::hook>, that is called whenever the popup is displayed.
96
97It's sole argument is the popup menu, which can be modified. The selection
98is in C<$_>, which can be used to decide wether to add something or not.
99It should either return nothing or a string and a code reference. The
100string will be used as button text and the code reference will be called
101when the button gets activated and should transform C<$_>.
102
103The following will add an entry C<a to b> that transforms all C<a>s in
104the selection to C<b>s, but only if the selection currently contains any
105C<a>s:
106
107 push urxvt::ext::selection_popup::hook, sub {
108 /a/ ? ("a to be" => sub { s/a/b/g }
109 : ()
110 };
111
112=item searchable-scrollback<hotkey> (enabled by default)
113
114Adds regex search functionality to the scrollback buffer, triggered
115by a hotkey (default: C<M-s>). While in search mode, normal terminal
116input/output is suspended and a regex is displayed at the bottom of the
117screen.
118
119Inputting characters appends them to the regex and continues incremental
120search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
121search upwards/downwards in the scrollback buffer, C<End> jumps to the
122bottom. C<Escape> leaves search mode and returns to the point where search
123was started, while C<Enter> or C<Return> stay at the current position and
124additionally stores the first match in the current line into the primary
125selection.
126
127=item selection-autotransform
128
129This selection allows you to do automatic transforms on a selection
130whenever a selection is made.
131
132It works by specifying perl snippets (most useful is a single C<s///>
133operator) that modify C<$_> as resources:
134
135 URxvt.selection-autotransform.0: transform
136 URxvt.selection-autotransform.1: transform
137 ...
138
139For example, the following will transform selections of the form
140C<filename:number>, often seen in compiler messages, into C<vi +$filename
141$word>:
142
143 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
144
145And this example matches the same,but replaces it with vi-commands you can
146paste directly into your (vi :) editor:
147
148 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/
149
150Of course, this can be modified to suit your needs and your editor :)
151
152To expand the example above to typical perl error messages ("XXX at
153FILENAME line YYY."), you need a slightly more elaborate solution:
154
155 URxvt.selection.pattern-0: ( at .*? line \\d+\\.)
156 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/
157
158The first line tells the selection code to treat the unchanging part of
159every error message as a selection pattern, and the second line transforms
160the message into vi commands to load the file.
161
162=item mark-urls
163
164Uses per-line display filtering (C<on_line_update>) to underline urls and
165make them clickable. When middle-clicked, the program specified in the
166resource C<urlLauncher> (default C<x-www-browser>) will be started with
167the URL as first argument.
168
169=item automove-background
170
171This is basically a one-line extension that dynamically changes the background pixmap offset
172to the window position, in effect creating the same effect as pseudo transparency with
173a custom pixmap. No scaling is supported in this mode. Exmaple:
174

177=item block-graphics-to-ascii
178
179A not very useful example of filtering all text output to the terminal,
180by replacing all line-drawing characters (U+2500 .. U+259F) by a
181similar-looking ascii character.
182
183=item digital-clock
184
185Displays a digital clock using the built-in overlay.
186
187=item example-refresh-hooks
188
189Displays a very simple digital clock in the upper right corner of the
190window. Illustrates overwriting the refresh callbacks to create your own
191overlays or changes.
192
193=item selection-pastebin
194
195This is a little rarely useful extension that Uploads the selection as
196textfile to a remote site (or does other things). (The implementation is
197not currently secure for use in a multiuser environment as it writes to
198F</tmp> directly.).
199
200It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
201i.e.
202
203 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
204
205Pressing this combination runs a command with C<%> replaced by the name of
206the textfile. This command can be set via a resource:
207
208 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
209
210And the default is likely not useful to anybody but the few people around
211here :)
212
213The name of the textfile is the hex encoded md5 sum of the selection, so
214the same content should lead to the same filename.
215
216After a successful upload the selection will be replaced by the text given
217in the C<selection-pastebin-url> resource (again, the % is the placeholder
218for the filename):
219

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 cololns (C<:>), and shoudl not contain colons themselves -
126there is also currently no escaping mechanism provided for this.

283=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.
284 138
285Dynamically enable the given hooks (named without the C<on_> prefix) for 139Example: matcher provides the C<matcher.launcher> ressource by having this

291Dynamically 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 cnanot 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:
