|

48 | C<--quoting-style=shell>. |
48 | |
49 | |
49 | It also offers the following bindable event: |
50 | A double-click usually selects the word under the cursor, further clicks |
|
|
51 | will enlarge the selection. |
|
|
52 | |
|
|
53 | The selection works by trying to match a number of regexes and displaying |
|
|
54 | them in increasing order of length. You can add your own regexes by |
|
|
55 | specifying resources of the form: |
|
|
56 | |
|
|
57 | URxvt.selection.pattern-0: perl-regex |
|
|
58 | URxvt.selection.pattern-1: perl-regex |
|
|
59 | ... |
|
|
60 | |
|
|
61 | The index number (0, 1...) must not have any holes, and each regex must |
|
|
62 | contain at least one pair of capturing parentheses, which will be used for |
|
|
63 | the match. For example, the followign adds a regex that matches everything |
|
|
64 | between two vertical bars: |
|
|
65 | |
|
|
66 | URxvt.selection.pattern-0: \\|([^|]+)\\| |
|
|
67 | |
|
|
68 | You can look at the source of the selection extension to see more |
|
|
69 | interesting uses, such as parsing a line from beginning to end. |

88 | =item selection-popup (enabled by default) |
67 | |
89 | |
68 | Displays a digital clock using the built-in overlay. |
90 | Binds a popup menu to Ctrl-Button3 that lets you convert the selection |
|
|
91 | text into various other formats/action (such as uri unescaping, perl |
|
|
92 | evalution, web-browser starting etc.), depending on content. |
|
|
93 | |
|
|
94 | Other extensions can extend this popup menu by pushing a code reference onto |
|
|
95 | C<@urxvt::ext::selection_popup::hook>, that is called whenever the popup is displayed. |
|
|
96 | |
|
|
97 | It's sole argument is the popup menu, which can be modified. The selection |
|
|
98 | is in C<$_>, which can be used to decide wether to add something or not. |
|
|
99 | It should either return nothing or a string and a code reference. The |
|
|
100 | string will be used as button text and the code reference will be called |
|
|
101 | when the button gets activated and should transform C<$_>. |
|
|
102 | |
|
|
103 | The following will add an entry C<a to b> that transforms all C<a>s in |
|
|
104 | the selection to C<b>s, but only if the selection currently contains any |
|
|
105 | C<a>s: |
|
|
106 | |
|
|
107 | push urxvt::ext::selection_popup::hook, sub { |
|
|
108 | /a/ ? ("a to be" => sub { s/a/b/g } |
|
|
109 | : () |
|
|
110 | }; |
|
|
111 | |
|
|
112 | =item searchable-scrollback<hotkey> (enabled by default) |
|
|
113 | |
|
|
114 | Adds regex search functionality to the scrollback buffer, triggered |
|
|
115 | by a hotkey (default: C<M-s>). While in search mode, normal terminal |
|
|
116 | input/output is suspended and a regex is displayed at the bottom of the |
|
|
117 | screen. |
|
|
118 | |
|
|
119 | Inputting characters appends them to the regex and continues incremental |
|
|
120 | search. C<BackSpace> removes a character from the regex, C<Up> and C<Down> |
|
|
121 | search upwards/downwards in the scrollback buffer, C<End> jumps to the |
|
|
122 | bottom. C<Escape> leaves search mode and returns to the point where search |
|
|
123 | was started, while C<Enter> or C<Return> stay at the current position and |
|
|
124 | additionally stores the first match in the current line into the primary |
|
|
125 | selection. |
|
|
126 | |
|
|
127 | =item selection-autotransform |
|
|
128 | |
|
|
129 | This selection allows you to do automatic transforms on a selection |
|
|
130 | whenever a selection is made. |
|
|
131 | |
|
|
132 | It works by specifying perl snippets (most useful is a single C<s///> |
|
|
133 | operator) that modify C<$_> as resources: |
|
|
134 | |
|
|
135 | URxvt.selection-autotransform.0: transform |
|
|
136 | URxvt.selection-autotransform.1: transform |
|
|
137 | ... |
|
|
138 | |
|
|
139 | For example, the following will transform selections of the form |
|
|
140 | C<filename:number>, often seen in compiler messages, into C<vi +$filename |
|
|
141 | $word>: |
|
|
142 | |
|
|
143 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
|
|
144 | |
|
|
145 | And this example matches the same,but replaces it with vi-commands you can |
|
|
146 | paste directly into your (vi :) editor: |
|
|
147 | |
|
|
148 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
149 | |
|
|
150 | Of course, this can be modified to suit your needs and your editor :) |
|
|
151 | |
|
|
152 | To expand the example above to typical perl error messages ("XXX at |
|
|
153 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
154 | |
|
|
155 | URxvt.selection.pattern-0: ( at .*? line \\d+\\.) |
|
|
156 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
157 | |
|
|
158 | The first line tells the selection code to treat the unchanging part of |
|
|
159 | every error message as a selection pattern, and the second line transforms |
|
|
160 | the message into vi commands to load the file. |

168 | |

|
169 | =item automove-background |
|
|
170 | |
|
|
171 | This is basically a one-line extension that dynamically changes the background pixmap offset |
|
|
172 | to the window position, in effect creating the same effect as pseudo transparency with |
|
|
173 | a custom pixmap. No scaling is supported in this mode. Exmaple: |

193 | =item selection-pastebin |
|
|
194 | |
|
|
195 | This is a little rarely useful extension that Uploads the selection as |
|
|
196 | textfile to a remote site (or does other things). (The implementation is |
|
|
197 | not currently secure for use in a multiuser environment as it writes to |
|
|
198 | F</tmp> directly.). |
|
|
199 | |
|
|
200 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
201 | i.e. |
|
|
202 | |
|
|
203 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
204 | |
|
|
205 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
206 | the textfile. This command can be set via a resource: |
|
|
207 | |
|
|
208 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
209 | |
|
|
210 | And the default is likely not useful to anybody but the few people around |
|
|
211 | here :) |
|
|
212 | |
|
|
213 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
214 | the same content should lead to the same filename. |
|
|
215 | |
|
|
216 | After a successful upload the selection will be replaced by the text given |
|
|
217 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
218 | for the filename): |
|
|

262 | =head2 Extension Objects |
|
|
263 | |
|
|
264 | Very perl extension is a perl class. A separate perl object is created |
|
|
265 | for each terminal and each extension and passed as the first parameter to |
|
|
266 | hooks. So extensions can use their C<$self> object without having to think |
|
|
267 | about other extensions, with the exception of methods and members that |
|
|
268 | begin with an underscore character C<_>: these are reserved for internal |
|
|
269 | use. |
|
|
270 | |
