21 |
|
|
|
22 |
root |
1.44 |
Everytime a terminal object gets created, extension scripts specified via |
23 |
|
|
the C<perl> resource are loaded and associated with it. |
24 |
root |
1.10 |
|
25 |
|
|
Scripts are compiled in a 'use strict' and 'use utf8' environment, and |
26 |
|
|
thus must be encoded as UTF-8. |
27 |
root |
1.6 |
|
28 |
|
|
Each script will only ever be loaded once, even in @@RXVT_NAME@@d, where |
29 |
root |
1.16 |
scripts will be shared (but not enabled) for all terminals. |

(More) intelligent selection. This extension tries to be more intelligent |
45 |
|
|
when the user extends selections (double-click). Right now, it tries to |
46 |
|
|
select urls and complete shell-quoted arguments, which is very convenient, |
47 |
|
|
too, if your F<ls> supports C<--quoting-style=shell>. |

Adds regex search functionality to the scrollback buffer, triggered |
75 |
|
|
by a hotkey (default: C<M-s>). When in search mode, normal terminal |
76 |
|
|
input/output is suspended. |
77 |

|
|
78 |
|
|
C</> starts an incremental regex search, C<n> searches further, C<p> or |
79 |
|
|
C<N> jump to the previous match, C<G> jumps to the bottom and clears the |
80 |

=head2 General API Considerations |
110 |
|
|
|
111 |
|
|
All objects (such as terminals, time watchers etc.) are typical |
112 |
|
|
reference-to-hash objects. The hash can be used to store anything you |
113 |
root |
1.7 |
like. All members starting with an underscore (such as C<_ptr> or |
114 |
root |
1.23 |
C<_hook>) are reserved for internal uses and B<MUST NOT> be accessed or |
115 |
root |
1.7 |
modified). |
116 |
root |
1.6 |
|
117 |
|
|
When objects are destroyed on the C++ side, the perl object hashes are |
118 |
|
|
emptied, so its best to store related objects such as time watchers and |
119 |
|
|
the like inside the terminal object so they get destroyed as soon as the |
120 |
|
|
terminal is destroyed. |
121 |
|
|
|

Argument names also often indicate the type of a parameter. Here are some |
123 |

Rxvt-unicodes special way of encoding text, where one "unicode" character |
130 |

1.78 |
always represents one screen cell. See L<ROW_t> for a discussion of this format. |

=item $string |
133 |
|
|
|
134 |
|
|
A perl text string, with an emphasis on I<text>. It can store all unicode |
135 |
|
|
characters and is to be distinguished with text encoded in a specific |
136 |
|
|
encoding (often locale-specific) and binary data. |

=head2 Extension Objects |
146 |
|
|
|
147 |
|
|
Very perl extension is a perl class. A separate perl object is created |
148 |
|
|
for each terminal and each extension and passed as the first parameter to |
149 |
|
|
hooks. So extensions can use their C<$self> object without having to think |
150 |
|
|
about other extensions, with the exception of methods and members that |
151 |
|
|
begin with an underscore character C<_>: these are reserved for internal |
152 |
|
|
use. |
153 |
|
|
|
154 |
|
|
Although it isn't a C<urxvt::term> object, you can call all methods of the |
155 |
|
|
C<urxvt::term> class on this object. |
156 |
|
|
|
157 |
|

extension. This member I<must not> be changed in any way. |

=item $self->enable ($hook_name => $cb, [$hook_name => $cb..]) |

Dynamically enable the given hooks (named without the C<on_> prefix) for |
169 |
|
|
this extension, replacing any previous hook. This is useful when you want |
170 |
|
|
to overwrite time-critical hooks only temporarily. |

|
172 |
|

=item $self->disable ($hook_name[, $hook_name..]) |

|
|
196 |
|
|
Called after a new terminal object has been initialized, but before |
197 |
root |
1.36 |
windows are created or the command gets run. Most methods are unsafe to |
198 |
|
|
call or deliver senseless data, as terminal size and other characteristics |
199 |

have not yet been determined. You can safely query and change resources, |

205 |
|
|
control sequences. Here is where you can react on changes to size-related |
206 |
|
|
variables. |

=item on_sel_make $term, $eventtime |

Called whenever a selection has been made by the user, but before the |
216 |
|
|
selection text is copied, so changes to the beginning, end or type of the |
217 |
|
|
selection will be honored. |
218 |
|
|
|
219 |
|
|
Returning a true value aborts selection making by urxvt, in which case you |
220 |
|
|
have to make a selection yourself by calling C<< $term->selection_grab >>. |

Called whenever a selection has been copied, but before the selection is |
225 |
|
|
requested from the server. The selection text can be queried and changed |
226 |
|
|
by calling C<< $term->selection >>. |
227 |

Called whenever the user tries to extend the selection (e.g. with a double |
233 |
|
|
click) and is either supposed to return false (normal operation), or |
234 |
|
|
should extend the selection itelf and return true to suppress the built-in |
235 |

241 |
|

Called whenever the view offset changes, i..e the user or program |
242 |
|
|
scrolls. Offset C<0> means display the normal terminal, positive values |
243 |
|
|
show this many lines of scrollback. |

=item on_scroll_back $term, $lines, $saved |
246 |
|
|
|
247 |
|
|
Called whenever lines scroll out of the terminal area into the scrollback |
248 |
|
|
buffer. C<$lines> is the number of lines scrolled out and may be larger |
249 |
|
|
than the scroll back buffer or the terminal. |
250 |
|
|
|
251 |
|
|
It is called before lines are scrolled out (so rows 0 .. min ($lines - 1, |
252 |
|
|
$nrow - 1) represent the lines to be scrolled out). C<$saved> is the total |
253 |
|
|
number of lines that will be in the scrollback buffer. |

root |
1.28 |
=item on_osc_seq $term, $string |
256 |

257 |
root |
1.29 |
Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC = |
258 |
|
|
operating system command) is processed. Cursor position and other state |
259 |
|
|
information is up-to-date when this happens. For interoperability, the |
260 |
|
|
string should start with the extension name and a colon, to distinguish |
261 |
|
|
it from commands for other extensions, and this might be enforced in the |
262 |
|
|
future. |
263 |
|
|
|
264 |
|
|
Be careful not ever to trust (in a security sense) the data you receive, |
265 |
|
|
as its source can not easily be controleld (e-mail content, messages from |
266 |
|
|
other users on the same system etc.). |

=item on_add_lines $term, $string |
269 |
|
|
|
270 |
|
|
Called whenever text is about to be output, with the text as argument. You |
271 |
|
|
can filter/change and output the text yourself by returning a true value |
272 |
|
|
and calling C<< $term->scr_add_lines >> yourself. Please note that this |
273 |
|
|
might be very slow, however, as your hook is called for B<all> text being |
274 |
|
|
output. |

281 |
root |
1.35 |
=item on_line_update $term, $row |
282 |
|
|
|
283 |
|
|
Called whenever a line was updated or changed. Can be used to filter |
284 |
|
|
screen output (e.g. underline urls or other useless stuff). Only lines |
285 |
|
|
that are being shown will be filtered, and, due to performance reasons, |
286 |
|
|
not always immediately. |
287 |
|
|
|
288 |
|
|
The row number is always the topmost row of the line if the line spans |
289 |
|
|
multiple rows. |
290 |
|
|
|
291 |
|
|
Please note that, if you change the line, then the hook might get called |
292 |
|
|
later with the already-modified line (e.g. if unrelated parts change), so |
293 |
|
|
you cannot just toggle rendition bits, but only set them. |

Fatally aborts execution with the given error message. Avoid at all |

costs! The only time this is acceptable is when the terminal process |
403 |

Calls C<rxvt_warn> with the given string which should not include a |
408 |
root |

newline. The module also overwrites the C<warn> builtin with a function |
409 |
|

that calls this function. |

Using this function has the advantage that its output ends up in the |

437 |
|
|
|
438 |
|

Rendition bitsets contain information about colour, font, font styles and |
439 |
|
|
similar information for each screen cell. |
440 |
|
|
|
441 |
|

The following "macros" deal with changes in rendition sets. You should |
442 |
|
|
never just create a bitset, you should always modify an existing one, |
443 |
|
|
as they contain important information required for correct operation of |
444 |

rxvt-unicode. |

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

further programming. The only exception is that you cannot wait on |

condition variables, but non-blocking condvar use is ok. What this means |
709 |
|
|
is that you cannot use blocking APIs, but the non-blocking variant should |

work. |

=item $value = $term->resource ($name[, $newval]) |

840 |
|
|
Returns the current resource value associated with a given name and |
841 |
|
|
optionally sets a new value. Setting values is most useful in the C<init> |
842 |
|
|
hook. Unset resources are returned and accepted as C<undef>. |
843 |
|
|
|
844 |
|
|
The new value must be properly encoded to a suitable character encoding |
845 |
|
|
before passing it to this method. Similarly, the returned value may need |
846 |
|
|
to be converted from the used encoding to text. |
847 |
|
|

848 |
|
|
Resource names are as defined in F<src/rsinc.h>. Colours can be specified |
849 |

|
as resource names of the form C<< color+<index> >>, e.g. C<color+5>. (will |
850 |
|
|
likely change). |
851 |
|
|
|
852 |
|
|
Please note that resource strings will currently only be freed when the |
853 |

terminal is destroyed, so changing options frequently will eat memory. |

1019 |
|
|
|
1020 |
|
|
XORs the rendition values in the given span with the provided value |
1021 |
|
|
(default: C<RS_RVid>). Useful in refresh hooks to provide effects similar |
1022 |
|
|

|
|
Similar to C<scr_xor_span>, but xors a rectangle instead. Trailing |
1027 |
|
|
whitespace will additionally be xored with the C<$rstyle2>, which defaults |
1028 |
|

Write the given text string to the screen, as if output by the application |
1038 |
|
|
running inside the terminal. It may not contain command sequences (escape |
1039 |
|
|
codes), but is free to use line feeds, carriage returns and tabs. The |
1040 |
|
|
string is a normal text string, not in locale-dependent encoding. |
1041 |
|
|
|
1042 |
|
|
Normally its not a good idea to use this function, as programs might be |
1043 |
|
|
confused by changes in cursor position or scrolling. Its useful inside a |
1044 |
|
|
C<on_add_lines> hook, though. |

Similar to C<scr_add_lines>, but the argument must be in the |
1049 |

locale-specific encoding of the terminal and can contain command sequences |
1050 |

Returns the text of the entire row with number C<$row_number>. Row C<0> |
1148 |
|
|
is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost |
1149 |
|
|
terminal line. The scrollback buffer starts at line C<-1> and extends to |
1150 |
root |
1.24 |
line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line |
1151 |
|
|
is requested. |
1152 |
root |
1.12 |
|
1153 |
root |
1.13 |
If C<$new_text> is specified, it will replace characters in the current |
1154 |
|
|
line, starting at column C<$start_col> (default C<0>), which is useful |
1155 |
root |
1.18 |
to replace only parts of a line. The font index in the rendition will |
1156 |
root |
1.13 |
automatically be updated. |
1157 |
root |
1.12 |
|
1158 |
|
|
C<$text> is in a special encoding: tabs and wide characters that use more |
1159 |
|
|
than one cell when displayed are padded with urxvt::NOCHAR characters |
1160 |
|
|
(C<chr 65535>). Characters with combining characters and other characters |
1161 |
|
|
that do not fit into the normal tetx encoding will be replaced with |
1162 |
|
|
characters in the private use area. |
1163 |
|
|
|
1164 |
|
|
You have to obey this encoding when changing text. The advantage is |
1165 |
|
|
that C<substr> and similar functions work on screen cells and not on |
1166 |
|
|
characters. |
1167 |
|
|
|
1168 |
|
|
The methods C<< $term->special_encode >> and C<< $term->special_decode >> |
1169 |
|
|
can be used to convert normal strings into this encoding and vice versa. |

|
|
Like C<< $term->ROW_t >>, but returns an arrayref with rendition |
1174 |
|
|
bitsets. Rendition bitsets contain information about colour, font, font |
1175 |
|
|
styles and similar information. See also C<< $term->ROW_t >>. |
1176 |

|
|

Returns the number of screen cells that are in use ("the line |

Returns true if the row is part of a multiple-row logical "line" (i.e. |
1190 |

joined with the following row), which means all characters are in use |
1191 |
