51 | arguments, which is very convenient, too, if your F<ls> supports |
|
|
52 | C<--quoting-style=shell>. |
48 | |
53 | |
49 | It also offers the following bindable event: |
54 | A double-click usually selects the word under the cursor, further clicks |
|
|
55 | will enlarge the selection. |
|
|
56 | |
|
|
57 | The selection works by trying to match a number of regexes and displaying |
|
|
58 | them in increasing order of length. You can add your own regexes by |
|
|
59 | specifying resources of the form: |
|
|
60 | |
|
|
61 | URxvt.selection.pattern-0: perl-regex |
|
|
62 | URxvt.selection.pattern-1: perl-regex |
|
|
63 | ... |
|
|
64 | |
|
|
65 | The index number (0, 1...) must not have any holes, and each regex must |
|
|
66 | contain at least one pair of capturing parentheses, which will be used for |
|
|
67 | the match. For example, the following adds a regex that matches everything |
|
|
68 | between two vertical bars: |
|
|
69 | |
|
|
70 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
|
|
71 | |
|
|
72 | Another example: Programs I use often output "absolute path: " at the |
|
|
73 | beginning of a line when they process multiple files. The following |
|
|
74 | pattern matches the filename (note, there is a single space at the very |
|
|
75 | end): |
|
|
76 | |
|
|
77 | URxvt.selection.pattern-0: ^(/[^:]+):\ |
|
|
78 | |
|
|

|
|
80 | interesting uses, such as parsing a line from beginning to end. |

94 | =item option-popup (enabled by default) |
|
|
95 | |
|
|
96 | Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at |
|
|
97 | runtime. |
|
|
98 | |
|
|
99 | Other extensions can extend this popup menu by pushing a code reference |
|
|
100 | onto C<@{ $term->{option_popup_hook} }>, which gets called whenever the |
|
|
101 | popup is being displayed. |
|
|
102 | |
|
|
103 | It's sole argument is the popup menu, which can be modified. It should |
|
|
104 | either return nothing or a string, the initial boolean value and a code |
|
|
105 | reference. The string will be used as button text and the code reference |
|
|
106 | will be called when the toggle changes, with the new boolean value as |
|
|
107 | first argument. |
|
|
108 | |
|
|
109 | The following will add an entry C<myoption> that changes |
|
|
110 | C<$self->{myoption}>: |
|
|
111 | |
|
|
112 | push @{ $self->{term}{option_popup_hook} }, sub { |
|
|
113 | ("my option" => $myoption, sub { $self->{myoption} = $_[0] }) |
|
|
114 | }; |
|
|
115 | |
|
|
116 | =item selection-popup (enabled by default) |
|
|
117 | |
|
|
118 | Binds a popup menu to Ctrl-Button3 that lets you convert the selection |
|
|
119 | text into various other formats/action (such as uri unescaping, perl |
|
|
120 | evaluation, web-browser starting etc.), depending on content. |
|
|
121 | |
|
|
122 | Other extensions can extend this popup menu by pushing a code reference |
|
|
123 | onto C<@{ $term->{selection_popup_hook} }>, which gets called whenever the |
|
|
124 | popup is being displayed. |
|
|
125 | |
|
|
126 | It's sole argument is the popup menu, which can be modified. The selection |
|
|
127 | is in C<$_>, which can be used to decide whether to add something or not. |
|
|
128 | It should either return nothing or a string and a code reference. The |
|
|
129 | string will be used as button text and the code reference will be called |
|
|
130 | when the button gets activated and should transform C<$_>. |
|
|
131 | |
|
|
132 | The following will add an entry C<a to b> that transforms all C<a>s in |
|
|
133 | the selection to C<b>s, but only if the selection currently contains any |
|
|
134 | C<a>s: |
|
|
135 | |
|
|
136 | push @{ $self->{term}{selection_popup_hook} }, sub { |
|
|
137 | /a/ ? ("a to be" => sub { s/a/b/g } |
|
|
138 | : () |
|
|
139 | }; |
|
|
140 | |
|
|
141 | =item searchable-scrollback<hotkey> (enabled by default) |
|
|
142 | |
|
|
143 | Adds regex search functionality to the scrollback buffer, triggered |
|
|
144 | by a hotkey (default: C<M-s>). While in search mode, normal terminal |
|
|
145 | input/output is suspended and a regex is displayed at the bottom of the |
|
|
146 | screen. |
|
|
147 | |
|
|
148 | Inputting characters appends them to the regex and continues incremental |
|
|
149 | search. C<BackSpace> removes a character from the regex, C<Up> and C<Down> |
|
|
150 | search upwards/downwards in the scrollback buffer, C<End> jumps to the |
|
|
151 | bottom. C<Escape> leaves search mode and returns to the point where search |
|
|
152 | was started, while C<Enter> or C<Return> stay at the current position and |
|
|
153 | additionally stores the first match in the current line into the primary |
|
|
154 | selection. |
|
|
155 | |
|
|
156 | The regex defaults to "(?i)", resulting in a case-insensitive search. To |
|
|
157 | get a case-sensitive search you can delete this prefix using C<BackSpace> |
|
|
158 | or simply use an uppercase character which removes the "(?i)" prefix. |
|
|
159 | |
|
|
160 | See L<perlre> for more info about perl regular expression syntax. |
|
|
161 | |
|
|
162 | =item readline (enabled by default) |
|
|
163 | |
|
|
164 | A support package that tries to make editing with readline easier. At |
|
|
165 | the moment, it reacts to clicking shift-left mouse button by trying to |
|
|
166 | move the text cursor to this position. It does so by generating as many |
|
|
167 | cursor-left or cursor-right keypresses as required (the this only works |
|
|
168 | for programs that correctly support wide characters). |
|
|
169 | |
|
|
170 | To avoid too many false positives, this is only done when: |
|
|
171 | |
|
|
172 | =over 4 |
|
|
173 | |
|
|
174 | =item - the tty is in ICANON state. |
|
|
175 | |
|
|
176 | =item - the text cursor is visible. |
|
|
177 | |
|
|
178 | =item - the primary screen is currently being displayed. |
|
|
179 | |
|
|
180 | =item - the mouse is on the same (multi-row-) line as the text cursor. |
|
|
181 | |
|
|
182 | =back |
|
|
183 | |
|
|
184 | The normal selection mechanism isn't disabled, so quick successive clicks |
|
|
185 | might interfere with selection creation in harmless ways. |
|
|
186 | |
|
|
187 | =item selection-autotransform |
|
|
188 | |
|
|
189 | This selection allows you to do automatic transforms on a selection |
|
|
190 | whenever a selection is made. |
|
|
191 | |
|
|
192 | It works by specifying perl snippets (most useful is a single C<s///> |
|
|
193 | operator) that modify C<$_> as resources: |
|
|
194 | |
|
|
195 | URxvt.selection-autotransform.0: transform |
|
|
196 | URxvt.selection-autotransform.1: transform |
|
|
197 | ... |
|
|
198 | |
|
|
199 | For example, the following will transform selections of the form |
|
|
200 | C<filename:number>, often seen in compiler messages, into C<vi +$filename |
|
|
201 | $word>: |
|
|
202 | |
|
|
203 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
|
|
204 | |
|
|
205 | And this example matches the same,but replaces it with vi-commands you can |
|
|
206 | paste directly into your (vi :) editor: |
|
|
207 | |
|
|
208 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
209 | |
|
|
210 | Of course, this can be modified to suit your needs and your editor :) |
|
|
211 | |
|
|
212 | To expand the example above to typical perl error messages ("XXX at |
|
|
213 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
214 | |
|
|
215 | URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) |
|
|
216 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
217 | |
|
|
218 | The first line tells the selection code to treat the unchanging part of |
|
|
219 | every error message as a selection pattern, and the second line transforms |
|
|
220 | the message into vi commands to load the file. |
|
|
221 | |
|
|
222 | =item tabbed |
|
|
223 | |
|
|
224 | This transforms the terminal into a tabbar with additional terminals, that |
|
|
225 | is, it implements what is commonly referred to as "tabbed terminal". The topmost line |
|
|
226 | displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
|
|
227 | button per tab. |
|
|
228 | |
|
|
229 | Clicking a button will activate that tab. Pressing B<Shift-Left> and |
|
|
230 | B<Shift-Right> will switch to the tab left or right of the current one, |
|
|
231 | while B<Shift-Down> creates a new tab. |
|
|
232 | |
|
|
233 | The tabbar itself can be configured similarly to a normal terminal, but |
|
|
234 | with a resource class of C<URxvt.tabbed>. In addition, it supports the |
|
|
235 | following four resources (shown with defaults): |
|
|
236 | |
|
|
237 | URxvt.tabbed.tabbar-fg: <colour-index, default 3> |
|
|
238 | URxvt.tabbed.tabbar-bg: <colour-index, default 0> |
|
|
239 | URxvt.tabbed.tab-fg: <colour-index, default 0> |

|
|
243 | indices. |

244 | |

|
245 | =item mark-urls |
|
|
246 | |
|
|
247 | Uses per-line display filtering (C<on_line_update>) to underline urls and |
|
|
248 | make them clickable. When middle-clicked, the program specified in the |
|
|
249 | resource C<urlLauncher> (default C<x-www-browser>) will be started with |
|
|
250 | the URL as first argument. |
|
|
251 | |
|
|
252 | =item xim-onthespot |
|
|
253 | |
|
|
254 | This (experimental) perl extension implements OnTheSpot editing. It does |
|
|
255 | not work perfectly, and some input methods don't seem to work well with |
|
|
256 | OnTheSpot editing in general, but it seems to work at leats for SCIM and |
|
|
257 | kinput2. |
|
|
258 | |
|
|
259 | You enable it by specifying this extension and a preedit style of |

264 | =item kuake<hotkey> |
|
|
265 | |
|
|
266 | A very primitive quake-console-like extension. It was inspired by a |
|
|
267 | description of how the programs C<kuake> and C<yakuake> work: Whenever the |
|
|
268 | user presses a global accelerator key (by default C<F10>), the terminal |
|
|
269 | will show or hide itself. Another press of the accelerator key will hide |
|
|
270 | or show it again. |
|
|
271 | |
|
|
272 | Initially, the window will not be shown when using this extension. |
|
|
273 | |
|
|
274 | This is useful if you need a single terminal thats not using any desktop |
|
|
275 | space most of the time but is quickly available at the press of a key. |
|
|
276 | |
|
|
277 | The accelerator key is grabbed regardless of any modifiers, so this |
|
|
278 | extension will actually grab a physical key just for this function. |
|
|
279 | |
|
|
280 | If you want a quake-like animation, tell your window manager to do so |
|
|
281 | (fvwm can do it). |
|
|
282 | |
|
|
283 | =item automove-background |
|
|
284 | |
|
|
285 | This is basically a very small extension that dynamically changes the |
|
|
286 | background pixmap offset to the window position, in effect creating the |
|
|
287 | same effect as pseudo transparency with a custom pixmap. No scaling is |
|
|
288 | supported in this mode. Example: |

|
302 | =item remote-clipboard |
|
|
303 | |
|
|
304 | Somewhat of a misnomer, this extension adds two menu entries to the |
|
|
305 | selection popup that allows one ti run external commands to store the |
|
|
306 | selection somewhere and fetch it again. |
|
|
307 | |
|
|
308 | We use it to implement a "distributed selection mechanism", which just |
|
|
309 | means that one command uploads the file to a remote server, and another |
|
|
310 | reads it. |
|
|
311 | |
|
|
312 | The commands can be set using the C<URxvt.remote-selection.store> and |
|
|
313 | C<URxvt.remote-selection.fetch> resources. The first should read the |
|
|
314 | selection to store from STDIN (always in UTF-8), the second should provide |
|
|
315 | the selection data on STDOUT (also in UTF-8). |
|
|
316 | |
|
|
317 | The defaults (which are likely useless to you) use rsh and cat: |
|
|
318 | |
|
|
319 | URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection' |
|
|
320 | URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection' |
|
|
321 | |
|
|
322 | =item selection-pastebin |
|
|
323 | |
|
|
324 | This is a little rarely useful extension that Uploads the selection as |
|
|
325 | textfile to a remote site (or does other things). (The implementation is |
|
|
326 | not currently secure for use in a multiuser environment as it writes to |
|
|
327 | F</tmp> directly.). |
|
|
328 | |
|
|
329 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
330 | i.e. |
|
|
331 | |
|
|
332 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
333 | |
|
|
334 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
335 | the textfile. This command can be set via a resource: |
|
|
336 | |
|
|
337 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
338 | |
|
|
339 | And the default is likely not useful to anybody but the few people around |
|
|
340 | here :) |
|
|
341 | |
|
|
342 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
343 | the same content should lead to the same filename. |
|
|
344 | |
|
|
345 | After a successful upload the selection will be replaced by the text given |
|
|
346 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
347 | for the filename): |
|
|
348 | |
|
|
349 | URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/% |
|
|
350 | |

|
351 | I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret |
|
|
352 | the double C</> characters as comment start. Use C<\057\057> instead, |

402 | =head2 Extension Objects |
|
|
403 | |
|
|
404 | Every perl extension is a perl class. A separate perl object is created |
|
|
405 | for each terminal, and each terminal has its own set of extenion objects, |
|
|
406 | which are passed as the first parameter to hooks. So extensions can use |
|
|
407 | their C<$self> object without having to think about clashes with other |
|
|
408 | extensions or other terminals, with the exception of methods and members |
|
|
409 | that begin with an underscore character C<_>: these are reserved for |
|
|
410 | internal use. |
|
|
411 | |
|
|
412 | Although it isn't a C<urxvt::term> object, you can call all methods of the |
|
|
413 | C<urxvt::term> class on this object. |

1045 | |
|
|
1046 | The sole purpose of this class is to deliver an interface to the |
|
|
1047 | C<AnyEvent> module - any module using it will work inside urxvt without |
|
|
1048 | further programming. The only exception is that you cannot wait on |
|
|
1049 | condition variables, but non-blocking condvar use is ok. What this means |
|
|
1050 | is that you cannot use blocking APIs, but the non-blocking variant should |
|
|
1051 | work. |
