47 | arguments, which is very convenient, too, if your F<ls> supports |
|
|
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. |
|
|
70 | |
|
|

71 | =item digital-clock |
94 | =item searchable-scrollback<hotkey> (enabled by default) |
72 | |
95 | |
73 | Displays a digital clock using the built-in overlay. |
96 | Adds regex search functionality to the scrollback buffer, triggered |
|
|
97 | by a hotkey (default: C<M-s>). While in search mode, normal terminal |
|
|
98 | input/output is suspended and a regex is displayed at the bottom of the |
|
|
99 | screen. |
|
|
100 | |
|
|
101 | Inputting characters appends them to the regex and continues incremental |
|
|
102 | search. C<BackSpace> removes a character from the regex, C<Up> and C<Down> |
|
|
103 | search upwards/downwards in the scrollback buffer, C<End> jumps to the |
|
|
104 | bottom. C<Escape> leaves search mode and returns to the point where search |
|
|
105 | was started, while C<Enter> or C<Return> stay at the current position and |
|
|
106 | additionally stores the first match in the current line into the primary |
|
|
107 | selection. |
|
|
108 | |
|
|
109 | =item selection-autotransform |
|
|
110 | |
|
|
111 | This selection allows you to do automatic transforms on a selection |
|
|
112 | whenever a selection is made. |
|
|
113 | |
|
|
114 | It works by specifying perl snippets (most useful is a single C<s///> |
|
|
115 | operator) that modify C<$_> as resources: |
|
|
116 | |
|
|
117 | URxvt.selection-autotransform.0: transform |
|
|
118 | URxvt.selection-autotransform.1: transform |
|
|
119 | ... |
|
|
120 | |
|
|
121 | For example, the following will transform selections of the form |
|
|
122 | C<filename:number>, often seen in compiler messages, into C<vi +$filename |
|
|
123 | $word>: |
|
|
124 | |
|
|
125 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/ |
|
|
126 | |
|
|
127 | And this example matches the same,but replaces it with vi-commands you can |
|
|
128 | paste directly into your (vi :) editor: |
|
|
129 | |
|
|
130 | URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/\\x1b:e \\Q$1\\E\\x0d:$2\\x0d/ |
|
|
131 | |
|
|
132 | Of course, this can be modified to suit your needs and your editor :) |
|
|
133 | |
|
|
134 | To expand the example above to typical perl error messages ("XXX at |
|
|
135 | FILENAME line YYY."), you need a slightly more elaborate solution: |
|
|
136 | |
|
|
137 | URxvt.selection.pattern-0: ( at .*? line \\d+\\.) |
|
|
138 | URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)\\.$/\x1b:e \\Q$1\E\\x0d:$2\\x0d/ |
|
|
139 | |
|
|
140 | The first line tells the selection code to treat the unchanging part of |
|
|
141 | every error message as a selection pattern, and the second line transforms |
|
|
142 | the message into vi commands to load the file. |

167 | =item selection-pastebin |
|
|
168 | |
|
|
169 | This is a little rarely useful extension that Uploads the selection as |
|
|
170 | textfile to a remote site (or does other things). (The implementation is |
|
|
171 | not currently secure for use in a multiuser environment as it writes to |
|
|
172 | F</tmp> directly.). |
|
|
173 | |
|
|
174 | It listens to the C<selection-pastebin:remote-pastebin> keyboard command, |
|
|
175 | i.e. |
|
|
176 | |
|
|
177 | URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin |
|
|
178 | |
|
|
179 | Pressing this combination runs a command with C<%> replaced by the name of |
|
|
180 | the textfile. This command can be set via a resource: |
|
|
181 | |
|
|
182 | URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/. |
|
|
183 | |
|
|
184 | And the default is likely not useful to anybody but the few people around |
|
|
185 | here :) |
|
|
186 | |
|
|
187 | The name of the textfile is the hex encoded md5 sum of the selection, so |
|
|
188 | the same content should lead to the same filename. |
|
|
189 | |
|
|
190 | After a successful upload the selection will be replaced by the text given |
|
|
191 | in the C<selection-pastebin-url> resource (again, the % is the placeholder |
|
|
192 | for the filename): |
|
|
193 | |

|

236 | =head2 Extension Objects |
|
|
237 | |
|
|
238 | Very perl extension is a perl class. A separate perl object is created |
|
|
239 | for each terminal and each extension and passed as the first parameter to |
|
|
240 | hooks. So extensions can use their C<$self> object without having to think |
|
|
241 | about other extensions, with the exception of methods and members that |
|
|
242 | begin with an underscore character C<_>: these are reserved for internal |
|
|
243 | use. |
|
|
244 | |
|
|
245 | Although it isn't a C<urxvt::term> object, you can call all methods of the |
|
|
246 | C<urxvt::term> class on this object. |
