34 | Or by adding them to the resource for extensions loaded by default: |
35 | Intelligent selection. This extension tries to be more intelligent |

36 | URxvt.perl-ext-common: default,automove-background,selection-autotransform |
|
|
37 | |
|
|
38 | selection (enabled by default) |
|
|
39 | (More) intelligent selection. This extension tries to be more |
36 | when the user extends selections (double-click). Right now, it tries |
40 | intelligent when the user extends selections (double-click and |
37 | to select urls and complete shell-quoted arguments, which is very |
41 | further clicks). Right now, it tries to select words, urls and |
|
|
42 | complete shell-quoted arguments, which is very convenient, too, if |
38 | convenient, too, if your ls supports "--quoting-style=shell". |
43 | your ls supports "--quoting-style=shell". |
39 | |
44 | |
40 | It also offers the following bindable event: |
45 | A double-click usually selects the word under the cursor, further |
|
|
46 | clicks will enlarge the selection. |
|
|
47 | |
|
|
48 | The selection works by trying to match a number of regexes and |
|
|
49 | displaying them in increasing order of length. You can add your own |
|
|
50 | regexes by specifying resources of the form: |
|
|
51 | |
|
|
52 | URxvt.selection.pattern-0: perl-regex |
|
|
53 | URxvt.selection.pattern-1: perl-regex |
|
|
54 | ... |
|
|
55 | |
|
|
56 | The index number (0, 1...) must not have any holes, and each regex |
|
|
57 | must contain at least one pair of capturing parentheses, which will |
|
|
58 | be used for the match. For example, the followign adds a regex that |
|
|
59 | matches everything between two vertical bars: |
|
|
60 | |
|
|
61 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
|
|
62 | |
|
|
63 | You can look at the source of the selection extension to see more |
|
|
64 | interesting uses, such as parsing a line from beginning to end. |
|
|
65 | |
|
|
66 | This extension also offers following bindable keyboard commands: |

|
|
72 | |
|
|
73 | option-popup (enabled by default) |
|
|
74 | Binds a popup menu to Ctrl-Button2 that lets you toggle (some) |
|
|
75 | options at runtime. |
|
|
76 | |
|
|
77 | selection-popup (enabled by default) |
|
|
78 | Binds a popup menu to Ctrl-Button3 that lets you convert the |
|
|
79 | selection text into various other formats/action (such as uri |
|
|
80 | unescaping, perl evaluation, web-browser starting etc.), depending |
|
|
81 | on content. |
|
|
82 | |
|
|
83 | Other extensions can extend this popup menu by pushing a code |
|
|
84 | reference onto "@{ $term-"{selection_popup_hook} }>, that is called |
|
|
85 | whenever the popup is displayed. |
|
|
86 | |
|
|
87 | It's sole argument is the popup menu, which can be modified. The |
|
|
88 | selection is in $_, which can be used to decide wether to add |
|
|
89 | something or not. It should either return nothing or a string and a |
|
|
90 | code reference. The string will be used as button text and the code |
|
|
91 | reference will be called when the button gets activated and should |
|
|
92 | transform $_. |
|
|
93 | |
|
|
94 | The following will add an entry "a to b" that transforms all "a"s in |
|
|
95 | the selection to "b"s, but only if the selection currently contains |
|
|
96 | any "a"s: |
|
|
97 | |
|
|
98 | push @{ $self->{term}{selection_popup_hook} }, sub { |
|
|
99 | /a/ ? ("a to be" => sub { s/a/b/g } |
|
|
100 | : () |
|
|
101 | }; |
|
|
102 | |
|
|
103 | searchable-scrollback<hotkey> (enabled by default) |
|
|
104 | Adds regex search functionality to the scrollback buffer, triggered |
|
|
105 | by a hotkey (default: "M-s"). While in search mode, normal terminal |
|
|
106 | input/output is suspended and a regex is displayed at the bottom of |
|
|
107 | the screen. |
|
|
108 | |
|
|
109 | Inputting characters appends them to the regex and continues |
|
|
110 | incremental search. "BackSpace" removes a character from the regex, |
|
|
111 | "Up" and "Down" search upwards/downwards in the scrollback buffer, |
|
|
112 | "End" jumps to the bottom. "Escape" leaves search mode and returns |
|
|
113 | to the point where search was started, while "Enter" or "Return" |
|
|
114 | stay at the current position and additionally stores the first match |
|
|
115 | in the current line into the primary selection. |
|
|
116 | |
|
|
117 | readline (enabled by default) |
|
|
118 | A support package that tries to make editing with readline easier. |
|
|
119 | At the moment, it reacts to clicking with the left mouse button by |
|
|
120 | trying to move the text cursor to this position. It does so by |
|
|
121 | generating as many cursor-left or cursor-right keypresses as |
|
|
122 | required (the this only works for programs that correctly support |
|
|
123 | wide characters). |
|
|
124 | |
|
|
125 | To avoid too many false positives, this is only done when: |
|
|
126 | |
|
|
127 | - the tty is in ICANON state. |
|
|
128 | - the text cursor is visible. |
|
|
129 | - the primary screen is currently being displayed. |
|
|
130 | - the mouse is on the same (multi-row-) line as the text cursor. |
|
|
131 | |
|
|
132 | The normal selection mechanism isn't disabled, so quick successive |
|
|
133 | clicks might interfere with selection creation in harmless ways. |
|
|
134 | |
|
|
135 | selection-autotransform |
|
|
136 | This selection allows you to do automatic transforms on a selection |
|
|
137 | whenever a selection is made. |
|
|
138 | |
|
|
139 | It works by specifying perl snippets (most useful is a single "s///" |
|
|
140 | operator) that modify $_ as resources: |
|
|
141 | |
|
|
142 | URxvt.selection-autotransform.0: transform |
|
|
143 | URxvt.selection-autotransform.1: transform |
|
|
144 | ... |
|
|
145 | |
|
|
146 | For example, the following will transform selections of the form |
|
|
147 | "filename:number", often seen in compiler messages, into "vi |
|
|
148 | +$filename $word": |
|
|
149 | |
|
|
150 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
|
|
151 | |
|
|
152 | And this example matches the same,but replaces it with vi-commands |
|
|
153 | you can paste directly into your (vi :) editor: |
|
|
154 | |
|
|
155 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
156 | |
|
|
157 | Of course, this can be modified to suit your needs and your editor |
|
|
158 | :) |
|
|
159 | |
|
|
160 | To expand the example above to typical perl error messages ("XXX at |
|
|
161 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
162 | |
|
|
163 | URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) |
|
|
164 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
165 | |
|
|
166 | The first line tells the selection code to treat the unchanging part |
|
|
167 | of every error message as a selection pattern, and the second line |
|
|
168 | transforms the message into vi commands to load the file. |
|
|
169 | |
|
|
170 | tabbed |
|
|
171 | This transforms the terminal into a tabbar with additional |
|
|
172 | terminals, that is, it implements what is commonly refered to as |
|
|
173 | "tabbed terminal". The topmost line displays a "[NEW]" button, |
|
|
174 | which, when clicked, will add a new tab, followed by one button per |
|
|
175 | tab. |
|
|
176 | |
|
|
177 | Clicking a button will activate that tab. Pressing Shift-Left and |
|
|
178 | Shift-Right will switch to the tab left or right of the current one, |
|
|
179 | while Shift-Down creates a new tab. |
|
|
180 | |
|
|
181 | mark-urls |
|
|
182 | Uses per-line display filtering ("on_line_update") to underline urls |
|
|
183 | and make them clickable. When middle-clicked, the program specified |
|
|
184 | in the resource "urlLauncher" (default "x-www-browser") will be |
|
|
185 | started with the URL as first argument. |
|
|
186 | |
|
|
187 | automove-background |
|
|
188 | This is basically a one-line extension that dynamically changes the |
|
|
189 | background pixmap offset to the window position, in effect creating |
|
|
190 | the same effect as pseudo transparency with a custom pixmap. No |
|
|
191 | scaling is supported in this mode. Exmaple: |
|
|
192 | |
|
|
193 | rxvt -pixmap background.xpm -pe automove-background |
|
|
194 | |
|
|
195 | block-graphics-to-ascii |
|
|
196 | A not very useful example of filtering all text output to the |
|
|
197 | terminal, by replacing all line-drawing characters (U+2500 .. |
|
|
198 | U+259F) by a similar-looking ascii character. |
46 | |

206 | your own overlays or changes. |
54 | |
207 | |
|
|
208 | selection-pastebin |
|
|
209 | This is a little rarely useful extension that Uploads the selection |
|
|
210 | as textfile to a remote site (or does other things). (The |
|
|
211 | implementation is not currently secure for use in a multiuser |
|
|
212 | environment as it writes to /tmp directly.). |
|
|
213 | |
|
|
214 | It listens to the "selection-pastebin:remote-pastebin" keyboard |
|
|
215 | command, i.e. |
|
|
216 | |
|
|
217 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
218 | |
|
|
219 | Pressing this combination runs a command with "%" replaced by the |
|
|
220 | name of the textfile. This command can be set via a resource: |
|
|
221 | |
|
|
222 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
223 | |
|
|
224 | And the default is likely not useful to anybody but the few people |
|
|
225 | around here :) |
|
|
226 | |
|
|
227 | The name of the textfile is the hex encoded md5 sum of the |
|
|
228 | selection, so the same content should lead to the same filename. |
|
|
229 | |
|
|
230 | After a successful upload the selection will be replaced by the text |
|
|
231 | given in the "selection-pastebin-url" resource (again, the % is the |
|
|
232 | placeholder for the filename): |
|
|
233 | |
|
|
234 | URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/% |

248 | |
|
|
249 | Argument names also often indicate the type of a parameter. Here are |
|
|
250 | some hints on what they mean: |
|
|
251 | |
|
|
252 | $text |
|
|
253 | Rxvt-unicodes special way of encoding text, where one "unicode" |
|
|
254 | character always represents one screen cell. See ROW_t for a |
|
|
255 | discussion of this format. |
|
|
256 | |
|
|
257 | $string |
|
|
258 | A perl text string, with an emphasis on *text*. It can store all |
|
|
259 | unicode characters and is to be distinguished with text encoded in a |
|
|
260 | specific encoding (often locale-specific) and binary data. |
|
|
261 | |
|
|
262 | $octets |
|
|
263 | Either binary data or - more common - a text string encoded in a |
|
|
264 | locale-specific way. |
|
|
265 | |
|
|
266 | Extension Objects |
|
|
267 | Very perl extension is a perl class. A separate perl object is created |
|
|
268 | for each terminal and each extension and passed as the first parameter |
|
|
269 | to hooks. So extensions can use their $self object without having to |
|
|
270 | think about other extensions, with the exception of methods and members |
|
|
271 | that begin with an underscore character "_": these are reserved for |
|
|
272 | internal use. |
|
|
273 | |
|
|
274 | Although it isn't a "urxvt::term" object, you can call all methods of |
|
|
275 | the "urxvt::term" class on this object. |
|
|
276 | |
|
|
277 | It has the following methods and data members: |
|
|
278 | |
|
|
279 | $urxvt_term = $self->{term} |
|
|
280 | Returns the "urxvt::term" object associated with this instance of |
|
|
281 | the extension. This member *must not* be changed in any way. |
|
|
282 | |
|
|
283 | $self->enable ($hook_name => $cb, [$hook_name => $cb..]) |
|
|
284 | Dynamically enable the given hooks (named without the "on_" prefix) |
|
|
285 | for this extension, replacing any previous hook. This is useful when |
|
|
286 | you want to overwrite time-critical hooks only temporarily. |
|
|
287 | |
|
|
288 | $self->disable ($hook_name[, $hook_name..]) |
|
|
289 | Dynamically disable the given hooks. |

388 | on_add_lines $term, $string |
|
|
389 | Called whenever text is about to be output, with the text as |
|
|
390 | argument. You can filter/change and output the text yourself by |
|
|
391 | returning a true value and calling "$term->scr_add_lines" yourself. |
|
|
392 | Please note that this might be very slow, however, as your hook is |

|
|
398 | |
|
|
399 | on_line_update $term, $row |
|
|
400 | Called whenever a line was updated or changed. Can be used to filter |
|
|
401 | screen output (e.g. underline urls or other useless stuff). Only |
|
|
402 | lines that are being shown will be filtered, and, due to performance |
|
|
403 | reasons, not always immediately. |
|
|
404 | |
|
|
405 | The row number is always the topmost row of the line if the line |
|
|
406 | spans multiple rows. |
|
|
407 | |
|
|
408 | Please note that, if you change the line, then the hook might get |
|
|
409 | called later with the already-modified line (e.g. if unrelated parts |
|
|
410 | change), so you cannot just toggle rendition bits, but only set |
|
|
411 | them. |

174 | Variables in the "urxvt" Package |
469 | Variables in the "urxvt" Package |
|
|
470 | $urxvt::LIBDIR |
|
|
471 | The rxvt-unicode library directory, where, among other things, the |
|
|
472 | perl modules and scripts are stored. |
|
|
473 | |
|
|
474 | $urxvt::RESCLASS, $urxvt::RESCLASS |
|
|
475 | The resource class and name rxvt-unicode uses to look up X |
|

476 | resources. |
|
|
477 | |
|
|
478 | $urxvt::RXVTNAME |
|
|
479 | The basename of the installed binaries, usually "urxvt". |
|
|
480 | |
175 | $urxvt::TERM |
481 | $urxvt::TERM |
176 | The current terminal. Whenever a callback/Hook is bein executed, |

482 | The current terminal. This variable stores the current "urxvt::term" |
|
|
483 | object, whenever a callback/hook is executing. |
|
|
484 | |
|
|
485 | @urxvt::TERM_INIT |
|
|
486 | All coderefs in this array will be called as methods of the next |
|
|
487 | newly created "urxvt::term" object (during the "on_init" phase). The |
|
|
488 | array gets cleared before the codereferences that were in it are |
|
|
489 | being executed, so coderefs can push themselves onto it again if |
|
|
490 | they so desire. |
|
|
491 | |
|
|
492 | This complements to the perl-eval commandline option, but gets |
|
|
493 | executed first. |
|
|
494 | |
|
|
495 | @urxvt::TERM_EXT |
|
|
496 | Works similar to @TERM_INIT, but contains perl package/class names, |
|
|
497 | which get registered as normal extensions after calling the hooks in |
|
|
498 | @TERM_INIT but before other extensions. Gets cleared just like |
|
|
499 | @TERM_INIT. |

|
|
580 | The "urxvt::anyevent" Class |
|
|
581 | The sole purpose of this class is to deliver an interface to the |
|
|
582 | "AnyEvent" module - any module using it will work inside urxvt without |
|
|
583 | further programming. The only exception is that you cannot wait on |
|
|
584 | condition variables, but non-blocking condvar use is ok. What this means |
|
|
585 | is that you cannot use blocking APIs, but the non-blocking variant |
|
|
586 | should work. |
|
|
587 | |
235 | The "urxvt::term" Class |
588 | The "urxvt::term" Class |
|
|
589 | $term = new urxvt::term $envhashref, $rxvtname, [arg...] |
|
|
590 | Creates a new terminal, very similar as if you had started it with |
|
|
591 | system "$rxvtname, arg...". $envhashref must be a reference to a |
|
|
592 | %ENV-like hash which defines the environment of the new terminal. |
|
|
593 | |
|
|
594 | Croaks (and probably outputs an error message) if the new instance |
|
|
595 | couldn't be created. Returns "undef" if the new instance didn't |
|
|
596 | initialise perl, and the terminal object otherwise. The "init" and |
|
|
597 | "start" hooks will be called during this call. |
|
|
598 | |
|
|
599 | $term->destroy |
|
|
600 | Destroy the terminal object (close the window, free resources etc.). |
|
|
601 | Please note that rxvt will not exit as long as any event watchers |
|
|
602 | (timers, io watchers) are still active. |
|
|
603 | |
|
|
604 | $term->exec_async ($cmd[, @args]) |
|
|
605 | Works like the combination of the "fork"/"exec" builtins, which |
|
|
606 | executes ("starts") programs in the background. This function takes |
|
|
607 | care of setting the user environment before exec'ing the command |
|
|
608 | (e.g. "PATH") and should be preferred over explicit calls to "exec" |
|
|
609 | or "system". |
|
|
610 | |
|
|
611 | Returns the pid of the subprocess or "undef" on error. |
|
|
612 | |
|
|
613 | $isset = $term->option ($optval[, $set]) |
|
|
614 | Returns true if the option specified by $optval is enabled, and |
|
|
615 | optionally change it. All option values are stored by name in the |
|
|
616 | hash %urxvt::OPTION. Options not enabled in this binary are not in |
|
|
617 | the hash. |

1092 | The "urxvt::iw" Class |
|
|
1093 | This class implements idle watchers, that get called automatically when |
|
|
1094 | the process is idle. They should return as fast as possible, after doing |
|
|
1095 | some useful work. |
|
|
1096 | |
|
|
1097 | $iw = new urxvt::iw |
