|
|
33 | This section describes the extensions delivered with this release. You can |
|
|
34 | find them in F<@@RXVT_LIBDIR@@/urxvt/perl/>. |
|
|
35 | |
|
|
36 | You can activate them like this: |
|
|
37 | |
|
|

|
|
39 | |
|
|
40 | Or by adding them to the resource for extensions loaded by default: |
|
|
41 | |
|
|
42 | URxvt.perl-ext-common: default,automove-background,selection-autotransform |
|
|
43 | |
|
|
44 | =over 4 |
|
|
45 | |
|
|
46 | =item selection (enabled by default) |
|
|
47 | |
|
|
48 | (More) intelligent selection. This extension tries to be more intelligent |
|
|
49 | when the user extends selections (double-click and further clicks). Right |
|
|
50 | now, it tries to select words, urls and complete shell-quoted |
|
|
51 | arguments, which is very convenient, too, if your F<ls> supports |
|
|
52 | C<--quoting-style=shell>. |
|
|
53 | |
|
|
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 followign adds a regex that matches everything |
|
|
68 | between two vertical bars: |
|
|
69 | |
|
|
70 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
|
|
71 | |
|
|
72 | You can look at the source of the selection extension to see more |
|
|
73 | interesting uses, such as parsing a line from beginning to end. |
|
|
74 | |
|
|
75 | This extension also offers following bindable keyboard commands: |
|
|
76 | |
|

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

193 | =item block-graphics-to-ascii |
|
|
194 | |
|
|
195 | A not very useful example of filtering all text output to the terminal, |
|
|
196 | by replacing all line-drawing characters (U+2500 .. U+259F) by a |
|
|
197 | similar-looking ascii character. |
|

|
201 | Displays a digital clock using the built-in overlay. |
|
|
202 | |
|
|
203 | =item example-refresh-hooks |
|
|
204 | |
|
|
205 | Displays a very simple digital clock in the upper right corner of the |
|
|
206 | window. Illustrates overwriting the refresh callbacks to create your own |
|
|
207 | overlays or changes. |
|
|
208 | |
|
|
209 | =item selection-pastebin |
|
|
210 | |
|
|
211 | This is a little rarely useful extension that Uploads the selection as |
|
|
212 | textfile to a remote site (or does other things). (The implementation is |
|
|
213 | not currently secure for use in a multiuser environment as it writes to |
|
|
214 | F</tmp> directly.). |
|
|
215 | |
|
|
216 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
217 | i.e. |
|
|
218 | |
|
|
219 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
220 | |
|
|
221 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
222 | the textfile. This command can be set via a resource: |
|
|
223 | |
|
|
224 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
225 | |
|
|
226 | And the default is likely not useful to anybody but the few people around |
|
|
227 | here :) |
|
|
228 | |
|
|
229 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
230 | the same content should lead to the same filename. |
|
|
231 | |
|
|
232 | After a successful upload the selection will be replaced by the text given |
|
|
233 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
234 | for the filename): |
|
|

280 | Very perl extension is a perl class. A separate perl object is created |
|
|
281 | for each terminal and each extension and passed as the first parameter to |
|
|
282 | hooks. So extensions can use their C<$self> object without having to think |
|
|
283 | about other extensions, with the exception of methods and members that |
|
|
284 | begin with an underscore character C<_>: these are reserved for internal |
|
|
285 | use. |

|
413 | future. |
|
|
414 | |
|
|
415 | Be careful not ever to trust (in a security sense) the data you receive, |
|
|
416 | as its source can not easily be controleld (e-mail content, messages from |

|
419 | =item on_add_lines $term, $string |
|
|
420 | |
|
|
421 | Called whenever text is about to be output, with the text as argument. You |
|
|
422 | can filter/change and output the text yourself by returning a true value |
|
|
423 | and calling C<< $term->scr_add_lines >> yourself. Please note that this |
|
|
424 | might be very slow, however, as your hook is called for B<all> text being |

|
432 | =item on_line_update $term, $row |
|
|
433 | |
|
|
434 | Called whenever a line was updated or changed. Can be used to filter |
|
|
435 | screen output (e.g. underline urls or other useless stuff). Only lines |
|
|
436 | that are being shown will be filtered, and, due to performance reasons, |
|
|
437 | not always immediately. |
|
|
438 | |
|
|
439 | The row number is always the topmost row of the line if the line spans |
|
|
440 | multiple rows. |
|
|
441 | |
|
|
442 | Please note that, if you change the line, then the hook might get called |
|
|
443 | later with the already-modified line (e.g. if unrelated parts change), so |
|
|
444 | you cannot just toggle rendition bits, but only set them. |

886 | further programming. The only exception is that you cannot wait on |
|
|
887 | condition variables, but non-blocking condvar use is ok. What this means |
|
|
888 | is that you cannot use blocking APIs, but the non-blocking variant should |
|
|
889 | work. |
