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 | 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 | |
|
|
79 | You can look at the source of the selection extension to see more |
|
|
80 | interesting uses, such as parsing a line from beginning to end. |
|
|
81 | |
|
|
82 | This extension also offers following bindable keyboard commands: |
|
|
83 | |
|
|
84 | =over 4 |
|
|
85 | |
|
|
86 | =item rot13 |
|
|
87 | |
|
|
88 | Rot-13 the selection when activated. Used via keyboard trigger: |
|
|
89 | |
|
|
90 | URxvt.keysym.C-M-r: perl:selection:rot13 |

|
|
93 | |
|
|
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 | =item selection-popup (enabled by default) |
|
|
100 | |
|
|
101 | Binds a popup menu to Ctrl-Button3 that lets you convert the selection |
|
|
102 | text into various other formats/action (such as uri unescaping, perl |
|
|
103 | evaluation, web-browser starting etc.), depending on content. |
|
|
104 | |
|
|
105 | Other extensions can extend this popup menu by pushing a code reference |
|
|
106 | onto C<@{ $term->{selection_popup_hook} }>, that is called whenever the |
|
|
107 | popup is displayed. |
|
|
108 | |
|
|
109 | It's sole argument is the popup menu, which can be modified. The selection |
|
|
110 | is in C<$_>, which can be used to decide wether to add something or not. |
|
|
111 | It should either return nothing or a string and a code reference. The |
|
|
112 | string will be used as button text and the code reference will be called |
|
|
113 | when the button gets activated and should transform C<$_>. |
|
|
114 | |
|
|
115 | The following will add an entry C<a to b> that transforms all C<a>s in |
|
|
116 | the selection to C<b>s, but only if the selection currently contains any |
|
|
117 | C<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 | |
|
|
126 | Adds regex search functionality to the scrollback buffer, triggered |
|
|
127 | by a hotkey (default: C<M-s>). While in search mode, normal terminal |
|
|
128 | input/output is suspended and a regex is displayed at the bottom of the |
|
|
129 | screen. |
|
|
130 | |
|
|
131 | Inputting characters appends them to the regex and continues incremental |
|
|
132 | search. C<BackSpace> removes a character from the regex, C<Up> and C<Down> |
|
|
133 | search upwards/downwards in the scrollback buffer, C<End> jumps to the |
|
|
134 | bottom. C<Escape> leaves search mode and returns to the point where search |
|
|
135 | was started, while C<Enter> or C<Return> stay at the current position and |
|
|
136 | additionally stores the first match in the current line into the primary |
|
|
137 | selection. |
|
|
138 | |
|
|
139 | =item readline (enabled by default) |
|
|
140 | |
|
|
141 | A support package that tries to make editing with readline easier. At the |
|
|
142 | moment, it reacts to clicking with the left mouse button by trying to |
|
|
143 | move the text cursor to this position. It does so by generating as many |
|
|
144 | cursor-left or cursor-right keypresses as required (the this only works |
|
|
145 | for programs that correctly support wide characters). |
|
|
146 | |
|
|
147 | To 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 | |
|
|
161 | The normal selection mechanism isn't disabled, so quick successive clicks |
|
|
162 | might interfere with selection creation in harmless ways. |
|
|
163 | |
|
|
164 | =item selection-autotransform |
|
|
165 | |
|
|
166 | This selection allows you to do automatic transforms on a selection |
|
|
167 | whenever a selection is made. |
|
|
168 | |
|
|
169 | It works by specifying perl snippets (most useful is a single C<s///> |
|
|
170 | operator) that modify C<$_> as resources: |
|
|
171 | |
|
|
172 | URxvt.selection-autotransform.0: transform |
|
|
173 | URxvt.selection-autotransform.1: transform |
|
|
174 | ... |
|
|
175 | |
|
|
176 | For example, the following will transform selections of the form |
|
|
177 | C<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$1\\E\\x0d/ |
|
|
181 | |
|
|
182 | And this example matches the same,but replaces it with vi-commands you can |
|
|
183 | paste directly into your (vi :) editor: |
|
|
184 | |
|
|
185 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
186 | |
|
|
187 | Of course, this can be modified to suit your needs and your editor :) |
|
|
188 | |
|
|
189 | To expand the example above to typical perl error messages ("XXX at |
|
|
190 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
191 | |
|
|
192 | URxvt.selection.pattern-0: ( at .*? line \\d+[,.]) |
|
|
193 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
194 | |
|
|
195 | The first line tells the selection code to treat the unchanging part of |
|
|
196 | every error message as a selection pattern, and the second line transforms |
|
|
197 | the message into vi commands to load the file. |
|
|
198 | |
|
|
199 | =item tabbed |
|
|
200 | |
|
|
201 | This transforms the terminal into a tabbar with additional terminals, that |
|
|
202 | is, it implements what is commonly refered to as "tabbed terminal". The topmost line |
|
|
203 | displays a "[NEW]" button, which, when clicked, will add a new tab, followed by one |
|
|
204 | button per tab. |
|
|
205 | |
|
|
206 | Clicking a button will activate that tab. Pressing B<Shift-Left> and |
|
|
207 | B<Shift-Right> will switch to the tab left or right of the current one, |
|
|
208 | while B<Shift-Down> creates a new tab. |
|
|
209 | |
|
|
210 | =item mark-urls |
|
|
211 | |
|
|
212 | Uses per-line display filtering (C<on_line_update>) to underline urls and |
|
|
213 | make them clickable. When middle-clicked, the program specified in the |
|
|
214 | resource C<urlLauncher> (default C<x-www-browser>) will be started with |
|
|
215 | the URL as first argument. |
|
|
216 | |
|
|
217 | =item xim-onthespot |
|
|
218 | |
|
|
219 | This (experimental) perl extension implements OnTheSpot editing. It does |
|
|
220 | not work perfectly, and some input methods don't seem to work well with |
|
|
221 | OnTheSpot editing in general, but it seems to work at leats for SCIM and |
|
|
222 | kinput2. |
|
|
223 | |
|
|
224 | You enable it by specifying this extension and a preedit style of |
|
|
225 | C<OnTheSpot>, i.e.: |

229 | =item automove-background |
|
|
230 | |
|
|
231 | This is basically a one-line extension that dynamically changes the background pixmap offset |
|
|
232 | to the window position, in effect creating the same effect as pseudo transparency with |
|
|
233 | a custom pixmap. No scaling is supported in this mode. Exmaple: |

237 | =item block-graphics-to-ascii |
|
|
238 | |
|
|
239 | A not very useful example of filtering all text output to the terminal, |
|
|
240 | by replacing all line-drawing characters (U+2500 .. U+259F) by a |
|
|
241 | similar-looking ascii character. |
|
|
242 | |
|
|
243 | =item digital-clock |
|
|
244 | |
|
|
245 | Displays a digital clock using the built-in overlay. |
|
|
246 | |
|
|
247 | =item remote-selection |
|
|
248 | |
|
|
249 | Somewhat of a misnomer, this extension adds two menu entries to the |
|
|
250 | selection popup that allows one ti run external commands to store the |
|
|
251 | selection somewhere and fetch it again. |
|
|
252 | |
|
|
253 | We use it to implement a "distributed selection mechanism", which just |
|
|
254 | means that one command uploads the file to a remote server, and another |
|
|
255 | reads it. |
|
|
256 | |
|
|
257 | The commands can be set using the C<URxvt.remote-selection.store> and |
|
|
258 | C<URxvt.remote-selection.fetch> resources. The first should read the |
|
|
259 | selection to store from STDIN (always in UTF-8), the second should provide |
|
|
260 | the selection data on STDOUT (also in UTF-8). |
|
|
261 | |
|
|
262 | The 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 | |
|
|
269 | This is a little rarely useful extension that Uploads the selection as |
|
|
270 | textfile to a remote site (or does other things). (The implementation is |
|
|
271 | not currently secure for use in a multiuser environment as it writes to |
|
|
272 | F</tmp> directly.). |
|
|
273 | |
|
|
274 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
275 | i.e. |
|
|
276 | |
|
|
277 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
278 | |
|
|
279 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
280 | the 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 | |
|
|
284 | And the default is likely not useful to anybody but the few people around |
|
|
285 | here :) |
|
|
286 | |
|
|
287 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
288 | the same content should lead to the same filename. |
|
|
289 | |
|
|
290 | After a successful upload the selection will be replaced by the text given |
|
|
291 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
292 | for the filename): |
|
|
293 | |
|
|
294 | URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/% |
|
|
295 | |

|
296 | =item example-refresh-hooks |
|
|
297 | |
|
|
298 | Displays a very simple digital clock in the upper right corner of the |
|
|
299 | window. Illustrates overwriting the refresh callbacks to create your own |
|
|
300 | overlays or changes. |
