|
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: ^(/[^:]+):\ |

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). |
|
|

|
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. |

|
|
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. |

|
247 | =item remote-clipboard |
|
|
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): |
