42 | =item selection (enabled by default) |
|
|
43 | |
|
|
44 | (More) intelligent selection. This extension tries to be more intelligent |
|
|
45 | when the user extends selections (double-click and further clicks). Right |
|
|
46 | now, it tries to select words, urls and complete shell-quoted |
|
|
47 | arguments, which is very convenient, too, if your F<ls> supports |
|
|
48 | C<--quoting-style=shell>. |
|
|
49 | |
|
|
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 | This extension also offers the following bindable keyboard command: |
|
|
72 | |
|
|
73 | =over 4 |
|
|
74 | |
|
|
75 | =item rot13 |
|
|

|
|
77 | Rot-13 the selection when activated. Used via keyboard trigger: |
|
|

83 | =item option-popup (enabled by default) |
|
|
84 | |
|
|
85 | Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at |
|
|
86 | runtime. |
|
|
87 | |
|
|
88 | =item selection-popup (enabled by default) |
|
|
89 | |
|
|
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 | =item searchable-scrollback<hotkey> (enabled by default) |
|
|
95 | |
|
|
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. |
|
|
143 | |
|
|
144 | =item mark-urls |
|
|
145 | |
|
|
146 | Uses per-line display filtering (C<on_line_update>) to underline urls and |
|
|
147 | make them clickable. When middle-clicked, the program specified in the |
|
|
148 | resource C<urlLauncher> (default C<x-www-browser>) will be started with |
|
|
149 | the URL as first argument. |
|
|
150 | |
|
|
151 | =item block-graphics-to-ascii |
|
|
152 | |
|
|
153 | A not very useful example of filtering all text output to the terminal, |
|
|
154 | by replacing all line-drawing characters (U+2500 .. U+259F) by a |
|
|
155 | similar-looking ascii character. |
|
|
156 | |
|
|
157 | =item digital-clock |
|
|
158 | |
|
|
159 | Displays a digital clock using the built-in overlay. |
|
|
160 | |
|
|
161 | =item example-refresh-hooks |
|
|
162 | |
|
|
163 | Displays a very simple digital clock in the upper right corner of the |
|
|
164 | window. Illustrates overwriting the refresh callbacks to create your own |
|
|
165 | overlays or changes. |

207 | =head2 Extension Objects |
|
|
208 | |
|
|
209 | Very perl extension is a perl class. A separate perl object is created |
|
|
210 | for each terminal and each extension and passed as the first parameter to |
|
|
211 | hooks. So extensions can use their C<$self> object without having to think |
|
|
212 | about other extensions, with the exception of methods and members that |
|
|
213 | begin with an underscore character C<_>: these are reserved for internal |
|
|
214 | use. |
|
|
215 | |
|
|
216 | Although it isn't a C<urxvt::term> object, you can call all methods of the |
|
|
217 | C<urxvt::term> class on this object. |
|
|
218 | |

|
|
336 | and calling C<< $term->scr_add_lines >> yourself. Please note that this |

|
349 | that are being shown will be filtered, and, due to performance reasons, |

|

523 | |

524 | Rendition bitsets contain information about colour, font, font styles and |

|

526 | |

527 | The following "macros" deal with changes in rendition sets. You should |
|
|
528 | never just create a bitset, you should always modify an existing one, |
|
|
529 | as they contain important information required for correct operation of |
|
|
530 | rxvt-unicode. |

783 | C<AnyEvent> module - any module using it will work inside urxvt without |

784 | further programming. The only exception is that you cannot wait on |
|
|
785 | condition variables, but non-blocking condvar use is ok. What this means |
|
|
786 | is that you cannot use blocking APIs, but the non-blocking variant should |

787 | work. |
