34 | =head1 PREPACKAGED EXTENSIONS |
|
|
35 | |
|
|
36 | This section describes the extensions delivered with this release. You can |
|
|
37 | find them in F<@@RXVT_LIBDIR@@/urxvt/perl/>. |
|
|
38 | |
|
|
39 | You can activate them like this: |
|
|
40 | |
|
|
41 | @@RXVT_NAME@@ -pe <extensionname> |
|
|
42 | |
|
|
43 | Or by adding them to the resource for extensions loaded by default: |
|
|
44 | |
|
|
45 | URxvt.perl-ext-common: default,selection-autotransform |
|
|
46 | |
|
|
47 | =over 4 |
|
|
48 | |
|
|
49 | =item selection (enabled by default) |
|
|
50 | |
|
|
51 | (More) intelligent selection. This extension tries to be more intelligent |
|
|
52 | when the user extends selections (double-click and further clicks). Right |
|
|
53 | now, it tries to select words, urls and complete shell-quoted |
|
|
54 | arguments, which is very convenient, too, if your F<ls> supports |
|
|
55 | C<--quoting-style=shell>. |
|
|
56 | |
|
|
57 | A double-click usually selects the word under the cursor, further clicks |
|
|
58 | will enlarge the selection. |
|
|
59 | |
|
|
60 | The selection works by trying to match a number of regexes and displaying |
|
|
61 | them in increasing order of length. You can add your own regexes by |
|
|
62 | specifying resources of the form: |
|
|
63 | |
|
|
64 | URxvt.selection.pattern-0: perl-regex |
|
|
65 | URxvt.selection.pattern-1: perl-regex |
|
|
66 | ... |
|
|
67 | |
|
|
68 | The index number (0, 1...) must not have any holes, and each regex must |
|
|
69 | contain at least one pair of capturing parentheses, which will be used for |
|
|
70 | the match. For example, the following adds a regex that matches everything |
|
|
71 | between two vertical bars: |
|
|
72 | |
|
|
73 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
|
|
74 | |
|
|
75 | Another example: Programs I use often output "absolute path: " at the |
|
|
76 | beginning of a line when they process multiple files. The following |
|
|
77 | pattern matches the filename (note, there is a single space at the very |
|
|
78 | end): |
|
|
79 | |
|
|
80 | URxvt.selection.pattern-0: ^(/[^:]+):\ |
|
|
81 | |
|
|
82 | You can look at the source of the selection extension to see more |
|
|
83 | interesting uses, such as parsing a line from beginning to end. |
|
|
84 | |
|
|
85 | This extension also offers following bindable keyboard commands: |
|
|
86 | |
|
|
87 | =over 4 |
|
|
88 | |
|
|
89 | =item rot13 |
|
|
90 | |
|
|
91 | Rot-13 the selection when activated. Used via keyboard trigger: |
|
|
92 | |
|
|
93 | URxvt.keysym.C-M-r: perl:selection:rot13 |
|
|
94 | |
|
|
95 | =back |
|
|
96 | |
|
|
97 | =item option-popup (enabled by default) |
|
|
98 | |
|
|
99 | Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at |
|
|
100 | runtime. |
|
|
101 | |
|
|
102 | Other extensions can extend this popup menu by pushing a code reference |
|
|
103 | onto C<@{ $term->{option_popup_hook} }>, which gets called whenever the |
|
|
104 | popup is being displayed. |
|
|
105 | |
|
|
106 | Its sole argument is the popup menu, which can be modified. It should |
|
|
107 | either return nothing or a string, the initial boolean value and a code |
|
|
108 | reference. The string will be used as button text and the code reference |
|
|
109 | will be called when the toggle changes, with the new boolean value as |
|
|
110 | first argument. |
|
|
111 | |
|
|
112 | The following will add an entry C<myoption> that changes |
|
|
113 | C<< $self->{myoption} >>: |
|
|
114 | |
|
|
115 | push @{ $self->{term}{option_popup_hook} }, sub { |
|
|
116 | ("my option" => $myoption, sub { $self->{myoption} = $_[0] }) |
|
|
117 | }; |
|
|
118 | |
|
|
119 | =item selection-popup (enabled by default) |
|
|
120 | |
|
|
121 | Binds a popup menu to Ctrl-Button3 that lets you convert the selection |
|
|
122 | text into various other formats/action (such as uri unescaping, perl |
|
|
123 | evaluation, web-browser starting etc.), depending on content. |
|
|
124 | |
|
|
125 | Other extensions can extend this popup menu by pushing a code reference |
|
|
126 | onto C<@{ $term->{selection_popup_hook} }>, which gets called whenever the |
|
|
127 | popup is being displayed. |
|
|
128 | |
|
|
129 | Its sole argument is the popup menu, which can be modified. The selection |
|
|
130 | is in C<$_>, which can be used to decide whether to add something or not. |
|
|
131 | It should either return nothing or a string and a code reference. The |
|
|
132 | string will be used as button text and the code reference will be called |
|
|
133 | when the button gets activated and should transform C<$_>. |
|
|
134 | |
|
|
135 | The following will add an entry C<a to b> that transforms all C<a>s in |
|
|
136 | the selection to C<b>s, but only if the selection currently contains any |
|
|
137 | C<a>s: |
|
|
138 | |
|
|
139 | push @{ $self->{term}{selection_popup_hook} }, sub { |
|
|
140 | /a/ ? ("a to b" => sub { s/a/b/g } |
|
|
141 | : () |
|
|
142 | }; |
|
|
143 | |
|
|
144 | =item searchable-scrollback<hotkey> (enabled by default) |
|
|
145 | |
|
|
146 | Adds regex search functionality to the scrollback buffer, triggered |
|
|
147 | by a hotkey (default: C<M-s>). While in search mode, normal terminal |
|
|
148 | input/output is suspended and a regex is displayed at the bottom of the |
|
|
149 | screen. |
|
|
150 | |
|
|
151 | Inputting characters appends them to the regex and continues incremental |
|
|
152 | search. C<BackSpace> removes a character from the regex, C<Up> and C<Down> |
|
|
153 | search upwards/downwards in the scrollback buffer, C<End> jumps to the |
|
|
154 | bottom. C<Escape> leaves search mode and returns to the point where search |
|
|
155 | was started, while C<Enter> or C<Return> stay at the current position and |
|
|
156 | additionally stores the first match in the current line into the primary |
|
|
157 | selection if the C<Shift> modifier is active. |
|
|
158 | |
|
|
159 | The regex defaults to "(?i)", resulting in a case-insensitive search. To |
|
|
160 | get a case-sensitive search you can delete this prefix using C<BackSpace> |
|
|
161 | or simply use an uppercase character which removes the "(?i)" prefix. |
|
|
162 | |
|
|
163 | See L<perlre> for more info about perl regular expression syntax. |
|
|
164 | |
|
|
165 | =item readline (enabled by default) |
|
|
166 | |
|
|
167 | A support package that tries to make editing with readline easier. At |
|
|
168 | the moment, it reacts to clicking shift-left mouse button by trying to |
|
|
169 | move the text cursor to this position. It does so by generating as many |
|
|
170 | cursor-left or cursor-right keypresses as required (this only works |
|
|
171 | for programs that correctly support wide characters). |
|
|
172 | |
|
|
173 | To avoid too many false positives, this is only done when: |
|
|
174 | |
|
|
175 | =over 4 |
|
|
176 | |
|
|
177 | =item - the tty is in ICANON state. |
|
|
178 | |
|
|
179 | =item - the text cursor is visible. |
|
|
180 | |
|
|
181 | =item - the primary screen is currently being displayed. |
|
|
182 | |
|
|
183 | =item - the mouse is on the same (multi-row-) line as the text cursor. |
|
|
184 | |
|
|
185 | =back |
|
|
186 | |
|
|
187 | The normal selection mechanism isn't disabled, so quick successive clicks |
|
|
188 | might interfere with selection creation in harmless ways. |
|
|
189 | |
|
|
190 | =item selection-autotransform |
|
|
191 | |
|
|
192 | This selection allows you to do automatic transforms on a selection |
|
|
193 | whenever a selection is made. |
|
|
194 | |
|
|
195 | It works by specifying perl snippets (most useful is a single C<s///> |
|
|
196 | operator) that modify C<$_> as resources: |
|
|
197 | |
|
|
198 | URxvt.selection-autotransform.0: transform |
|
|
199 | URxvt.selection-autotransform.1: transform |
|
|
200 | ... |
|
|
201 | |
|
|
202 | For example, the following will transform selections of the form |
|
|
203 | C<filename:number>, often seen in compiler messages, into C<vi +$filename |
|
|
204 | $word>: |
|
|
205 | |
|
|
206 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
|
|
207 | |
|
|
208 | And this example matches the same,but replaces it with vi-commands you can |
|
|
209 | paste directly into your (vi :) editor: |
|
|
210 | |
|
|
211 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
212 | |
|
|
213 | Of course, this can be modified to suit your needs and your editor :) |
|
|
214 | |
|
|
215 | To expand the example above to typical perl error messages ("XXX at |
|
|
216 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
217 | |
|
|
218 | URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) |
|
|
219 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
220 | |
|
|
221 | The first line tells the selection code to treat the unchanging part of |
|
|
222 | every error message as a selection pattern, and the second line transforms |
|
|
223 | the message into vi commands to load the file. |
|
|
224 | |
|
|
225 | =item tabbed |
|
|
226 | |
|
|
227 | This transforms the terminal into a tabbar with additional terminals, that |
|
|
228 | is, it implements what is commonly referred to as "tabbed terminal". The topmost line |
|
|
229 | displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
|
|
230 | button per tab. |
|
|
231 | |
|
|
232 | Clicking a button will activate that tab. Pressing B<Shift-Left> and |
|
|
233 | B<Shift-Right> will switch to the tab left or right of the current one, |
|
|
234 | while B<Shift-Down> creates a new tab. |
|
|
235 | |
|
|
236 | The tabbar itself can be configured similarly to a normal terminal, but |
|
|
237 | with a resource class of C<URxvt.tabbed>. In addition, it supports the |
|
|
238 | following four resources (shown with defaults): |
|
|
239 | |
|
|
240 | URxvt.tabbed.tabbar-fg: <colour-index, default 3> |
|
|
241 | URxvt.tabbed.tabbar-bg: <colour-index, default 0> |
|
|
242 | URxvt.tabbed.tab-fg: <colour-index, default 0> |
|
|
243 | URxvt.tabbed.tab-bg: <colour-index, default 1> |
|
|
244 | |
|
|
245 | See I<COLOR AND GRAPHICS> in the @@RXVT_NAME@@(1) manpage for valid |
|
|
246 | indices. |
|
|
247 | |
|
|
248 | =item matcher |
|
|
249 | |
|
|
250 | Uses per-line display filtering (C<on_line_update>) to underline text |
|
|
251 | matching a certain pattern and make it clickable. When clicked with the |
|
|
252 | mouse button specified in the C<matcher.button> resource (default 2, or |
|
|
253 | middle), the program specified in the C<matcher.launcher> resource |
|
|
254 | (default, the C<urlLauncher> resource, C<sensible-browser>) will be started |
|
|
255 | with the matched text as first argument. The default configuration is |
|
|
256 | suitable for matching URLs and launching a web browser, like the |
|
|
257 | former "mark-urls" extension. |
|
|
258 | |
|
|
259 | The default pattern to match URLs can be overridden with the |
|
|
260 | C<matcher.pattern.0> resource, and additional patterns can be specified |
|
|
261 | with numbered patterns, in a manner similar to the "selection" extension. |
|
|
262 | The launcher can also be overridden on a per-pattern basis. |
|
|
263 | |
|
|
264 | It is possible to activate the most recently seen match or a list of matches |
|
|
265 | from the keyboard. Simply bind a keysym to "perl:matcher:last" or |
|
|
266 | "perl:matcher:list" as seen in the example below. |
|
|
267 | |
|
|
268 | Example configuration: |
|
|
269 | |
|
|
270 | URxvt.perl-ext: default,matcher |
|
|
271 | URxvt.urlLauncher: sensible-browser |
|
|
272 | URxvt.keysym.C-Delete: perl:matcher:last |
|
|
273 | URxvt.keysym.M-Delete: perl:matcher:list |
|
|
274 | URxvt.matcher.button: 1 |
|
|
275 | URxvt.matcher.pattern.1: \\bwww\\.[\\w-]+\\.[\\w./?&@#-]*[\\w/-] |
|
|
276 | URxvt.matcher.pattern.2: \\B(/\\S+?):(\\d+)(?=:|$) |
|
|
277 | URxvt.matcher.launcher.2: gvim +$2 $1 |
|
|
278 | |
|
|
279 | =item xim-onthespot |
|
|
280 | |
|
|
281 | This (experimental) perl extension implements OnTheSpot editing. It does |
|
|
282 | not work perfectly, and some input methods don't seem to work well with |
|
|
283 | OnTheSpot editing in general, but it seems to work at least for SCIM and |
|
|
284 | kinput2. |
|
|
285 | |
|
|
286 | You enable it by specifying this extension and a preedit style of |
|
|
287 | C<OnTheSpot>, i.e.: |
|
|
288 | |
|
|
289 | @@RXVT_NAME@@ -pt OnTheSpot -pe xim-onthespot |
|
|
290 | |
|
|
291 | =item kuake<hotkey> |
|
|
292 | |
|
|
293 | A very primitive quake-console-like extension. It was inspired by a |
|
|
294 | description of how the programs C<kuake> and C<yakuake> work: Whenever the |
|
|
295 | user presses a global accelerator key (by default C<F10>), the terminal |
|
|
296 | will show or hide itself. Another press of the accelerator key will hide |
|
|
297 | or show it again. |
|
|
298 | |
|
|
299 | Initially, the window will not be shown when using this extension. |
|
|
300 | |
|
|
301 | This is useful if you need a single terminal that is not using any desktop |
|
|
302 | space most of the time but is quickly available at the press of a key. |
|
|
303 | |
|
|
304 | The accelerator key is grabbed regardless of any modifiers, so this |
|
|
305 | extension will actually grab a physical key just for this function. |
|
|
306 | |
|
|
307 | If you want a quake-like animation, tell your window manager to do so |
|
|
308 | (fvwm can do it). |
|
|
309 | |
|
|
310 | =item overlay-osc |
|
|
311 | |
|
|
312 | This extension implements some OSC commands to display timed popups on the |
|
|
313 | screen - useful for status displays from within scripts. You have to read |
|
|
314 | the sources for more info. |
|
|
315 | |
|
|
316 | =item block-graphics-to-ascii |
|
|
317 | |
|
|
318 | A not very useful example of filtering all text output to the terminal |
|
|
319 | by replacing all line-drawing characters (U+2500 .. U+259F) by a |
|
|
320 | similar-looking ascii character. |
|
|
321 | |
|
|
322 | =item digital-clock |
|
|
323 | |
|
|
324 | Displays a digital clock using the built-in overlay. |
|
|
325 | |
|
|
326 | =item remote-clipboard |
|
|
327 | |
|
|
328 | Somewhat of a misnomer, this extension adds two menu entries to the |
|
|
329 | selection popup that allows one to run external commands to store the |
|
|
330 | selection somewhere and fetch it again. |
|
|
331 | |
|
|
332 | We use it to implement a "distributed selection mechanism", which just |
|
|
333 | means that one command uploads the file to a remote server, and another |
|
|
334 | reads it. |
|
|
335 | |
|
|
336 | The commands can be set using the C<URxvt.remote-selection.store> and |
|
|
337 | C<URxvt.remote-selection.fetch> resources. The first should read the |
|
|
338 | selection to store from STDIN (always in UTF-8), the second should provide |
|
|
339 | the selection data on STDOUT (also in UTF-8). |
|
|
340 | |
|
|
341 | The defaults (which are likely useless to you) use rsh and cat: |
|
|
342 | |
|
|
343 | URxvt.remote-selection.store: rsh ruth 'cat >/tmp/distributed-selection' |
|
|
344 | URxvt.remote-selection.fetch: rsh ruth 'cat /tmp/distributed-selection' |
|
|
345 | |
|
|
346 | =item selection-pastebin |
|
|
347 | |
|
|
348 | This is a little rarely useful extension that uploads the selection as |
|
|
349 | textfile to a remote site (or does other things). (The implementation is |
|
|
350 | not currently secure for use in a multiuser environment as it writes to |
|
|
351 | F</tmp> directly.). |
|
|
352 | |
|
|
353 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |

354 | i.e. |
|
|
355 | |
|
|
356 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
357 | |
|
|
358 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
359 | the textfile. This command can be set via a resource: |
|
|
360 | |
|
|
361 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
362 | |
|
|
363 | And the default is likely not useful to anybody but the few people around |
|
|
364 | here :) |
|
|
365 | |
|
|
366 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
367 | the same content should lead to the same filename. |
|
|
368 | |
|
|
369 | After a successful upload the selection will be replaced by the text given |
|
|
370 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
371 | for the filename): |
|
|
372 | |
|
|
373 | URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/% |
|
|
374 | |
|
|
375 | I<Note to xrdb users:> xrdb uses the C preprocessor, which might interpret |
|
|
376 | the double C</> characters as comment start. Use C<\057\057> instead, |
|
|
377 | which works regardless of whether xrdb is used to parse the resource file |
|
|
378 | or not. |

380 | =item macosx-clipboard and macosx-clipboard-native |
|
|
381 | |
|
|
382 | These two modules implement an extended clipboard for Mac OS X. They are |
|
|
383 | used like this: |
|
|
384 | |
|
|
385 | URxvt.perl-ext-common: default,macosx-clipboard |
|
|
386 | URxvt.keysym.M-c: perl:macosx-clipboard:copy |
|
|
387 | URxvt.keysym.M-v: perl:macosx-clipboard:paste |
|
|
388 | |
|
|
389 | The difference between them is that the native variant requires a |
|
|
390 | perl from apple's devkit or so, and C<macosx-clipboard> requires the |
|
|
391 | C<Mac::Pasteboard> module, works with other perls, has fewer bugs, is |
|
|
392 | simpler etc. etc. |

409 | bubble with the text "Beep, Beep" using notify-send: |

453 | =head2 Extension Objects |
|
|
454 | |
|
|
455 | Every perl extension is a perl class. A separate perl object is created |
|
|
456 | for each terminal, and each terminal has its own set of extension objects, |
|
|
457 | which are passed as the first parameter to hooks. So extensions can use |
|
|
458 | their C<$self> object without having to think about clashes with other |
|
|
459 | extensions or other terminals, with the exception of methods and members |
|
|
460 | that begin with an underscore character C<_>: these are reserved for |
|
|
461 | internal use. |
|
|
462 | |
|
|
463 | Although it isn't a C<urxvt::term> object, you can call all methods of the |
|
|
464 | C<urxvt::term> class on this object. |
|
|
465 | |

|
596 | string should start with the extension name (sans -osc) and a semicolon, |

1149 | C<AnyEvent> module - any module using it will work inside urxvt without |

|
1150 | further programming. The only exception is that you cannot wait on |
|
|
1151 | condition variables, but non-blocking condvar use is ok. What this means |
|
|
1152 | is that you cannot use blocking APIs, but the non-blocking variant should |

|
1153 | work. |

1264 | C<$rxvtname, arg...>. C<$envhashref> must be a reference to a C<%ENV>-like |

1265 | hash which defines the environment of the new terminal. |
|
|
1266 | |
|
|
1267 | Croaks (and probably outputs an error message) if the new instance |

|
1269 | initialise perl, and the terminal object otherwise. The C<init> and |
|
|
1270 | C<start> hooks will be called before this call returns, and are free to |
|
|
1271 | refer to global data (which is race free). |

1687 | =item $screen = $term->current_screen |
|
|
1688 | |
|

|
|
1690 | |
|
|
1691 | =item $cursor_is_hidden = $term->hidden_cursor |
|
|
1692 | |
|
|
1693 | Returns whether the cursor is currently hidden or not. |
|
|
1694 | |
|
|
1695 | =item $view_start = $term->view_start ([$newvalue]) |
|
|
1696 | |
|
|
1697 | Returns the row number of the topmost displayed line. Maximum value is |
|
|
1698 | C<0>, which displays the normal terminal contents. Lower values scroll |
|
|
1699 | this many lines into the scrollback buffer. |
|
|
1700 | |
|
|
1701 | =item $term->want_refresh |
|
|
1702 | |
|
|
1703 | Requests a screen refresh. At the next opportunity, rxvt-unicode will |
|
|
1704 | compare the on-screen display with its stored representation. If they |
|
|
1705 | differ, it redraws the differences. |
|
|
1706 | |
|
|
1707 | Used after changing terminal contents to display them. |
|
|
1708 | |
|
|
1709 | =item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
|
|
1710 | |
|
|
1711 | Returns the text of the entire row with number C<$row_number>. Row C<< $term->top_row >> |
|
|
1712 | is the topmost terminal line, row C<< $term->nrow-1 >> is the bottommost |
|
|
1713 | terminal line. Nothing will be returned if a nonexistent line |
|
|
1714 | is requested. |
|
|
1715 | |
|
|
1716 | If C<$new_text> is specified, it will replace characters in the current |
|
|
1717 | line, starting at column C<$start_col> (default C<0>), which is useful |
|
|
1718 | to replace only parts of a line. The font index in the rendition will |
|
|
1719 | automatically be updated. |
|
|
1720 | |
|
|
1721 | C<$text> is in a special encoding: tabs and wide characters that use more |
|
|
1722 | than one cell when displayed are padded with C<$urxvt::NOCHAR> (chr 65535) |
|
|
1723 | characters. Characters with combining characters and other characters that |
|
|
1724 | do not fit into the normal text encoding will be replaced with characters |
|
|
1725 | in the private use area. |
|
|
1726 | |
|
|
1727 | You have to obey this encoding when changing text. The advantage is |
|
|
1728 | that C<substr> and similar functions work on screen cells and not on |
|
|
1729 | characters. |
|
|
1730 | |
|
|
1731 | The methods C<< $term->special_encode >> and C<< $term->special_decode >> |
|
|
1732 | can be used to convert normal strings into this encoding and vice versa. |
|
|
1733 | |
|
|
1734 | =item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
|
|
1735 | |
|
|
1736 | Like C<< $term->ROW_t >>, but returns an arrayref with rendition |
|
|
1737 | bitsets. Rendition bitsets contain information about colour, font, font |
|
|
1738 | styles and similar information. See also C<< $term->ROW_t >>. |
|
|
1739 | |
|
|
1740 | When setting rendition, the font mask will be ignored. |
|
|
1741 | |
|
|
1742 | See the section on RENDITION, above. |
|
|
1743 | |
|
|
1744 | =item $length = $term->ROW_l ($row_number[, $new_length]) |
|
|
1745 | |
|
|
1746 | Returns the number of screen cells that are in use ("the line |
|
|
1747 | length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the |
|
|
1748 | line is joined with the following one. |
|
|
1749 | |
|
|
1750 | =item $bool = $term->is_longer ($row_number) |
|
|
1751 | |
|
|
1752 | Returns true if the row is part of a multiple-row logical "line" (i.e. |
|
|
1753 | joined with the following row), which means all characters are in use |
|
|
1754 | and it is continued on the next row (and possibly a continuation of the |
|
|
1755 | previous row(s)). |
|
|
1756 | |
|
|
1757 | =item $line = $term->line ($row_number) |
|
|
1758 | |
|
|
1759 | Create and return a new C<urxvt::line> object that stores information |
|
|
1760 | about the logical line that row C<$row_number> is part of. It supports the |
|
|
1761 | following methods: |

|
|
1768 | |
|
|
1769 | =item $rend = $line->r ([$new_rend]) |
|
|
1770 | |
|

1771 | Returns or replaces the full rendition array of the line, similar to C<ROW_r> |
|
|
1772 | |
|
|
1773 | =item $length = $line->l |
|
|
1774 | |

1778 | |
|

1779 | =item $rownum = $line->end |
|
|
1780 | |
|
|
1781 | Return the row number of the first/last row of the line, respectively. |
|
|
1782 | |
|
|
1783 | =item $offset = $line->offset_of ($row, $col) |
|
|
1784 | |
|
|
1785 | Returns the character offset of the given row|col pair within the logical |
|
|
1786 | line. Works for rows outside the line, too, and returns corresponding |
|
|
1787 | offsets outside the string. |
|
|
1788 | |
|
|
1789 | =item ($row, $col) = $line->coord_of ($offset) |
|
