45 49which can be bound to a key and invoked by the user. An extension can
46=item selection (enabled by default) 50define the resources it support using so called META comments,
47 51described below. Similarly to builtin resources, extension resources

49when the user extends selections (double-click and further clicks). Right 53replaced by C<->), in which case the corresponding extension is loaded

51arguments, which is very convenient, too, if your F<ls> supports 55comments for its resources.
52C<--quoting-style=shell>.
53
54A double-click usually selects the word under the cursor, further clicks
55will enlarge the selection.
56
57The selection works by trying to match a number of regexes and displaying
58them in increasing order of length. You can add your own regexes by
59specifying resources of the form:
60
61 URxvt.selection.pattern-0: perl-regex
62 URxvt.selection.pattern-1: perl-regex
63 ...
64
65The index number (0, 1...) must not have any holes, and each regex must
66contain at least one pair of capturing parentheses, which will be used for
67the match. For example, the followign adds a regex that matches everything
68between two vertical bars:
69
70 URxvt.selection.pattern-0: \\|([^|]+)\\|
71
72Another example: Programs I use often output "absolute path: " at the
73beginning of a line when they process multiple files. The following
74pattern matches the filename (note, there is a single space at the very
75end):
76
77 URxvt.selection.pattern-0: ^(/[^:]+):\
78
79You can look at the source of the selection extension to see more
80interesting uses, such as parsing a line from beginning to end.
81
82This extension also offers following bindable keyboard commands:
83
84=over 4
85
86=item rot13
87
88Rot-13 the selection when activated. Used via keyboard trigger:
89
90 URxvt.keysym.C-M-r: perl:selection:rot13
91
92=back
93
94=item option-popup (enabled by default)
95
96Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at
97runtime.
98
99=item selection-popup (enabled by default)
100
101Binds a popup menu to Ctrl-Button3 that lets you convert the selection
102text into various other formats/action (such as uri unescaping, perl
103evaluation, web-browser starting etc.), depending on content.
104
105Other extensions can extend this popup menu by pushing a code reference
106onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the
107popup is displayed.
108
109It's sole argument is the popup menu, which can be modified. The selection
110is in C<$_>, which can be used to decide wether to add something or not.
111It should either return nothing or a string and a code reference. The
112string will be used as button text and the code reference will be called
113when the button gets activated and should transform C<$_>.
114
115The following will add an entry C<a to b> that transforms all C<a>s in
116the selection to C<b>s, but only if the selection currently contains any
117C<a>s:
118
119 push @{ $self->{term}{selection_popup_hook} }, sub {
120 /a/ ? ("a to be" => sub { s/a/b/g }
121 : ()
122 };
123
124=item searchable-scrollback<hotkey> (enabled by default)
125
126Adds regex search functionality to the scrollback buffer, triggered
127by a hotkey (default: C<M-s>). While in search mode, normal terminal
128input/output is suspended and a regex is displayed at the bottom of the
129screen.
130
131Inputting characters appends them to the regex and continues incremental
132search. C<BackSpace> removes a character from the regex, C<Up> and C<Down>
133search upwards/downwards in the scrollback buffer, C<End> jumps to the
134bottom. C<Escape> leaves search mode and returns to the point where search
135was started, while C<Enter> or C<Return> stay at the current position and
136additionally stores the first match in the current line into the primary
137selection.
138
139=item readline (enabled by default)
140
141A support package that tries to make editing with readline easier. At the
142moment, it reacts to clicking with the left mouse button by trying to
143move the text cursor to this position. It does so by generating as many
144cursor-left or cursor-right keypresses as required (the this only works
145for programs that correctly support wide characters).
146
147To avoid too many false positives, this is only done when:
148
149=over 4
150
151=item - the tty is in ICANON state.
152
153=item - the text cursor is visible.
154
155=item - the primary screen is currently being displayed.
156
157=item - the mouse is on the same (multi-row-) line as the text cursor.
158
159=back
160
161The normal selection mechanism isn't disabled, so quick successive clicks
162might interfere with selection creation in harmless ways.
163
164=item selection-autotransform
165
166This selection allows you to do automatic transforms on a selection
167whenever a selection is made.
168
169It works by specifying perl snippets (most useful is a single C<s///>
170operator) that modify C<$_> as resources:
171
172 URxvt.selection-autotransform.0: transform
173 URxvt.selection-autotransform.1: transform
174 ...
175
176For example, the following will transform selections of the form
177C<filename:number>, often seen in compiler messages, into C<vi +$filename
178$word>:
179
180 URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
181
182And this example matches the same,but replaces it with vi-commands you can
183paste directly into your (vi :) editor:
184
185 URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
186
187Of course, this can be modified to suit your needs and your editor :)
188
189To expand the example above to typical perl error messages ("XXX at
190FILENAME line YYY."), you need a slightly more elaborate solution:
191
192 URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
193 URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
194
195The first line tells the selection code to treat the unchanging part of
196every error message as a selection pattern, and the second line transforms
197the message into vi commands to load the file.
198
199=item tabbed
200
201This transforms the terminal into a tabbar with additional terminals, that
202is, it implements what is commonly refered to as "tabbed terminal". The topmost line
203displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one
204button per tab.
205
206Clicking a button will activate that tab. Pressing B<Shift-Left> and
207B<Shift-Right> will switch to the tab left or right of the current one,
208while B<Shift-Down> creates a new tab.
209
210=item mark-urls
211
212Uses per-line display filtering (C<on_line_update>) to underline urls and
213make them clickable. When middle-clicked, the program specified in the
214resource C<urlLauncher> (default C<x-www-browser>) will be started with
215the URL as first argument.
216
217=item xim-onthespot
218
219This (experimental) perl extension implements OnTheSpot editing. It does
220not work perfectly, and some input methods don't seem to work well with
221OnTheSpot editing in general, but it seems to work at leats for SCIM and
222kinput2.
223
224You enable it by specifying this extension and a preedit style of
225C<OnTheSpot>, i.e.:
226
227 @@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot
228
229=item automove-background
230
231This is basically a one-line extension that dynamically changes the background pixmap offset
232to the window position, in effect creating the same effect as pseudo transparency with
233a custom pixmap. No scaling is supported in this mode. Exmaple:
234
235 @@RXVT_NAME@@ -pixmap background.xpm -pe automove-background
236
237=item block-graphics-to-ascii
238
239A not very useful example of filtering all text output to the terminal,
240by replacing all line-drawing characters (U+2500 .. U+259F) by a
241similar-looking ascii character.
242
243=item digital-clock
244
245Displays a digital clock using the built-in overlay.
246
247=item remote-selection
248
249Somewhat of a misnomer, this extension adds two menu entries to the
250selection popup that allows one ti run external commands to store the
251selection somewhere and fetch it again.
252
253We use it to implement a "distributed selection mechanism", which just
254means that one command uploads the file to a remote server, and another
255reads it.
256
257The commands can be set using the C<URxvt.remote-selection.store> and
258C<URxvt.remote-selection.fetch> resources. The first should read the
259selection to store from STDIN (always in UTF-8), the second should provide
260the selection data on STDOUT (also in UTF-8).
261
262The defaults (which are likely useless to you) use rsh and cat:
263
264 URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection'
265 URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection'
266
267=item selection-pastebin
268
269This is a little rarely useful extension that Uploads the selection as
270textfile to a remote site (or does other things). (The implementation is
271not currently secure for use in a multiuser environment as it writes to
272F</tmp> directly.).
273
274It listens to the C<selection-pastebin:remote-pastebin> keyboard command,
275i.e.
276
277 URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
278
279Pressing this combination runs a command with C<%> replaced by the name of
280the textfile. This command can be set via a resource:
281
282 URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
283
284And the default is likely not useful to anybody but the few people around
285here :)
286
287The name of the textfile is the hex encoded md5 sum of the selection, so
288the same content should lead to the same filename.
289
290After a successful upload the selection will be replaced by the text given
291in the C<selection-pastebin-url> resource (again, the % is the placeholder
292for the filename):
293
294 URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
295
296=item example-refresh-hooks
297
298Displays a very simple digital clock in the upper right corner of the
299window. Illustrates overwriting the refresh callbacks to create your own
300overlays or changes.

355 116
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 cololns (C<:>), and shoudl not contain colons themselves -
126there is also currently no escaping mechanism provided for this.

363=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.

365Dynamically enable the given hooks (named without the C<on_> prefix) for 139Example: matcher provides the C<matcher.launcher> ressource by having this

371Dynamically 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:
