=head1 DESCRIPTION |
21 |
|
|
|
22 |
root |
1.144 |
Every time a terminal object gets created, extension scripts specified via |
23 |
root |
1.44 |
the C<perl> resource are loaded and associated with it. |
24 |
root |
1.10 |
|
25 |
root |
1.215 |
Scripts are compiled in a 'use strict "vars"' and 'use utf8' environment, and |
26 |
root |
1.10 |
thus must be encoded as UTF-8. |
27 |
root |
1.6 |
|
28 |
root |
1.226 |
Each script will only ever be loaded once, even in urxvtd, where |
29 |
root |
1.16 |
scripts will be shared (but not enabled) for all terminals. |
30 |
root |
1.6 |
|
31 |

You can disable the embedded perl interpreter by setting both "perl-ext" |
32 |
|
|
and "perl-ext-common" resources to the empty string. |

36 |
root |
1.218 |
A number of extensions are delivered with this release. You can find them |
37 |
root |
1.226 |
in F<< <libdir>/urxvt/perl/ >>, and the documentation can be viewed using |
38 |
|
|
F<< man urxvt-<EXTENSIONNAME> >>. |
39 |
root |
1.15 |
|
40 |
|
|
You can activate them like this: |
41 |
|
|
|
42 |
root |
1.226 |
urxvt -pe <extensionname> |
43 |
root |
1.15 |
|
44 |
root |
1.111 |
Or by adding them to the resource for extensions loaded by default: |
45 |
|
|
|
46 |
ayin |
1.160 |
URxvt.perl-ext-common: default,selection-autotransform |
47 |
root |
1.111 |
|
48 |
root |
1.218 |
Extensions that add command line parameters or resources on their own are |
49 |
sf-exg |
1.219 |
loaded automatically when used. |

=head2 General API Considerations |
54 |
|
|
|
55 |
|
|
All objects (such as terminals, time watchers etc.) are typical |
56 |
|
|
reference-to-hash objects. The hash can be used to store anything you |
57 |
root |
1.7 |
like. All members starting with an underscore (such as C<_ptr> or |
58 |
root |
1.23 |
C<_hook>) are reserved for internal uses and B<MUST NOT> be accessed or |
59 |
root |
1.7 |
modified). |
60 |
root |
1.6 |
|
61 |
|
|
When objects are destroyed on the C++ side, the perl object hashes are |
62 |
|
|
emptied, so its best to store related objects such as time watchers and |
63 |
|
|
the like inside the terminal object so they get destroyed as soon as the |
64 |
|
|
terminal is destroyed. |
65 |
|
|
|
66 |
root |
1.33 |
Argument names also often indicate the type of a parameter. Here are some |
67 |
|
|
hints on what they mean: |

1.182 |
Rxvt-unicode's special way of encoding text, where one "unicode" character |
74 |
root |
1.78 |
always represents one screen cell. See L<ROW_t> for a discussion of this format. |

root |
1.33 |
|
76 |
|
|
=item $string |
77 |
|
|
|
78 |
|
|
A perl text string, with an emphasis on I<text>. It can store all unicode |
79 |
|
|
characters and is to be distinguished with text encoded in a specific |
80 |
|
|
encoding (often locale-specific) and binary data. |
81 |
|
|
|
82 |
|
|
=item $octets |
83 |
|
|

=head2 Extension Objects |
96 |
|
|
|
97 |
root |
1.139 |
Every perl extension is a perl class. A separate perl object is created |
98 |
sf-exg |
1.193 |
for each terminal, and each terminal has its own set of extension objects, |
99 |
root |
1.145 |
which are passed as the first parameter to hooks. So extensions can use |
100 |
|
|
their C<$self> object without having to think about clashes with other |
101 |
|
|
extensions or other terminals, with the exception of methods and members |
102 |
|
|
that begin with an underscore character C<_>: these are reserved for |
103 |
|
|
internal use. |
104 |
root |
1.69 |
|
105 |
|
|
Although it isn't a C<urxvt::term> object, you can call all methods of the |
106 |
|
|
C<urxvt::term> class on this object. |
107 |
|
|
|
108 |
root |
1.222 |
Additional methods only supported for extension objects are described in |
109 |
|
|
the C<urxvt::extension> section below. |

|
111 |
root |
1.1 |
=head2 Hooks |
112 |
|
|
|
113 |
root |
1.43 |
The following subroutines can be declared in extension files, and will be |
114 |
root |
1.23 |
called whenever the relevant event happens. |
115 |
|
|
|
116 |
root |
1.144 |
The first argument passed to them is an extension object as described in |
117 |
root |
1.69 |
the in the C<Extension Objects> section. |
118 |
|
|
|
119 |
root |
1.112 |
B<All> of these hooks must return a boolean value. If any of the called |
120 |
|
|
hooks returns true, then the event counts as being I<consumed>, and the |
121 |
|
|
relevant action might not be carried out by the C++ code. |

=item on_init $term |
128 |
|
|
|
129 |
|
|
Called after a new terminal object has been initialized, but before |
130 |
root |
1.36 |
windows are created or the command gets run. Most methods are unsafe to |
131 |
|
|
call or deliver senseless data, as terminal size and other characteristics |
132 |
root |
1.112 |
have not yet been determined. You can safely query and change resources |
133 |
|
|
and options, though. For many purposes the C<on_start> hook is a better |
134 |
|
|
place. |
135 |
|
|
|
136 |
|
|
=item on_start $term |
137 |
|
|
|
138 |
|
|
Called at the very end of initialisation of a new terminal, just before |
139 |
root |
1.144 |
trying to map (display) the toplevel and returning to the main loop. |
140 |

|
141 |
|
|
=item on_destroy $term |
142 |
|
|
|
143 |

Called whenever something tries to destroy terminal, when the terminal is |
144 |
|
|
still fully functional (not for long, though). |
145 |
root |
1.1 |
|
146 |
|
|
=item on_reset $term |
147 |
|
|
|
148 |
|
|
Called after the screen is "reset" for any reason, such as resizing or |
149 |
|
|
control sequences. Here is where you can react on changes to size-related |
150 |
|
|
variables. |

Called just after the child process has been C<fork>ed. |
155 |
|
|
|
156 |
|
|
=item on_child_exit $term, $status |
157 |
|
|
|
158 |
|
|
Called just after the child process has exited. C<$status> is the status |
159 |
|
|
from C<waitpid>. |

|
|
|
161 |
root |
1.1 |
=item on_sel_make $term, $eventtime |
162 |
|
|
|
163 |
|
|
Called whenever a selection has been made by the user, but before the |
164 |
|
|
selection text is copied, so changes to the beginning, end or type of the |
165 |
|
|
selection will be honored. |
166 |
|
|
|
167 |
|
|
Returning a true value aborts selection making by urxvt, in which case you |
168 |
|
|
have to make a selection yourself by calling C<< $term->selection_grab >>. |
169 |
|
|
|
170 |
|
|
=item on_sel_grab $term, $eventtime |
171 |
|
|
|
172 |
|
|
Called whenever a selection has been copied, but before the selection is |
173 |
|
|
requested from the server. The selection text can be queried and changed |
174 |
|
|
by calling C<< $term->selection >>. |
175 |
|
|
|
176 |
root |
1.144 |
Returning a true value aborts selection grabbing. It will still be highlighted. |

|
178 |
root |
1.22 |
=item on_sel_extend $term |
179 |
|
|
|
180 |
|
|
Called whenever the user tries to extend the selection (e.g. with a double |
181 |
|
|
click) and is either supposed to return false (normal operation), or |
182 |
root |
1.144 |
should extend the selection itself and return true to suppress the built-in |
183 |
root |
1.85 |
processing. This can happen multiple times, as long as the callback |
184 |
|
|
returns true, it will be called on every further click by the user and is |
185 |
|
|
supposed to enlarge the selection more and more, if possible. |
186 |
root |
1.22 |
|
187 |
|
|
See the F<selection> example extension. |
188 |

root |
1.1 |
=item on_view_change $term, $offset |
190 |
|
|
|
191 |
root |
1.144 |
Called whenever the view offset changes, i.e. the user or program |
192 |
root |
1.1 |
scrolls. Offset C<0> means display the normal terminal, positive values |
193 |
|
|
show this many lines of scrollback. |
194 |
|
|
|
195 |
|
|
=item on_scroll_back $term, $lines, $saved |
196 |
|
|
|
197 |
|
|
Called whenever lines scroll out of the terminal area into the scrollback |
198 |
|
|
buffer. C<$lines> is the number of lines scrolled out and may be larger |
199 |
|
|
than the scroll back buffer or the terminal. |
200 |
|
|
|
201 |
|
|
It is called before lines are scrolled out (so rows 0 .. min ($lines - 1, |
202 |
|
|
$nrow - 1) represent the lines to be scrolled out). C<$saved> is the total |
203 |
|
|
number of lines that will be in the scrollback buffer. |
204 |
|
|
|
205 |
root |
1.171 |
=item on_osc_seq $term, $op, $args, $resp |
206 |
root |
1.137 |
|
207 |
|
|
Called on every OSC sequence and can be used to suppress it or modify its |
208 |
root |
1.171 |
behaviour. The default should be to return an empty list. A true value |
209 |
root |
1.137 |
suppresses execution of the request completely. Make sure you don't get |
210 |
root |
1.171 |
confused by recursive invocations when you output an OSC sequence within |
211 |
root |
1.137 |
this callback. |
212 |
|
|
|
213 |
|
|
C<on_osc_seq_perl> should be used for new behaviour. |
214 |
|
|
|
215 |
root |
1.171 |
=item on_osc_seq_perl $term, $args, $resp |
216 |
root |
1.28 |
|
217 |
root |
1.29 |
Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC = |
218 |
|
|
operating system command) is processed. Cursor position and other state |
219 |
|
|
information is up-to-date when this happens. For interoperability, the |
220 |
root |
1.171 |
string should start with the extension name (sans -osc) and a semicolon, |
221 |
|
|
to distinguish it from commands for other extensions, and this might be |
222 |
|
|
enforced in the future. |
223 |
|
|
|
224 |
|
|
For example, C<overlay-osc> uses this: |
225 |
|
|
|
226 |
|
|
sub on_osc_seq_perl { |
227 |
|
|
my ($self, $osc, $resp) = @_; |
228 |
|
|
|
229 |
|
|
return unless $osc =~ s/^overlay;//; |
230 |
|
|
|
231 |
|
|
... process remaining $osc string |
232 |
|
|
} |
233 |
root |
1.29 |
|
234 |
|
|
Be careful not ever to trust (in a security sense) the data you receive, |
235 |
root |
1.144 |
as its source can not easily be controlled (e-mail content, messages from |
236 |
root |
1.29 |
other users on the same system etc.). |
237 |
root |
1.28 |
|
238 |
root |
1.171 |
For responses, C<$resp> contains the end-of-args separator used by the |
239 |
|
|
sender. |

|
241 |
root |
1.33 |
=item on_add_lines $term, $string |
242 |
|
|
|
243 |
|
|
Called whenever text is about to be output, with the text as argument. You |
244 |
|
|
can filter/change and output the text yourself by returning a true value |
245 |
|
|
and calling C<< $term->scr_add_lines >> yourself. Please note that this |
246 |
|
|
might be very slow, however, as your hook is called for B<all> text being |
247 |
|
|
output. |
248 |
|
|
|
249 |
root |
1.72 |
=item on_tt_write $term, $octets |
250 |
|
|
|
251 |
|
|
Called whenever some data is written to the tty/pty and can be used to |
252 |
|
|
suppress or filter tty input. |
253 |
|
|
|
254 |
sf-exg |
1.187 |
=item on_tt_paste $term, $octets |
255 |
|
|
|
256 |
|
|
Called whenever text is about to be pasted, with the text as argument. You |
257 |
|
|
can filter/change and paste the text yourself by returning a true value |
258 |
|
|
and calling C<< $term->tt_paste >> yourself. C<$octets> is |
259 |
|
|
locale-encoded. |
260 |
|
|
|
261 |
root |
1.35 |
=item on_line_update $term, $row |
262 |
|
|
|
263 |
|
|
Called whenever a line was updated or changed. Can be used to filter |
264 |
|
|
screen output (e.g. underline urls or other useless stuff). Only lines |
265 |
|
|
that are being shown will be filtered, and, due to performance reasons, |
266 |
|
|
not always immediately. |
267 |
|
|
|
268 |
|
|
The row number is always the topmost row of the line if the line spans |
269 |
|
|
multiple rows. |
270 |
|
|
|
271 |
|
|
Please note that, if you change the line, then the hook might get called |
272 |
|
|
later with the already-modified line (e.g. if unrelated parts change), so |
273 |
|
|
you cannot just toggle rendition bits, but only set them. |
274 |

275 |
root |
1.1 |
=item on_refresh_begin $term |
276 |
|
|
|
277 |
root |
1.171 |
Called just before the screen gets redrawn. Can be used for overlay or |
278 |
|
|
similar effects by modifying the terminal contents in refresh_begin, and |
279 |
root |
1.1 |
restoring them in refresh_end. The built-in overlay and selection display |
280 |
|
|
code is run after this hook, and takes precedence. |

282 |
|
|
=item on_refresh_end $term |
283 |

=item on_user_command $term, $string *DEPRECATED* |
287 |
root |
1.11 |
|
288 |
root |
1.144 |
Called whenever a user-configured event is being activated (e.g. via |
289 |
root |
1.130 |
a C<perl:string> action bound to a key, see description of the B<keysym> |
290 |

1.226 |
resource in the urxvt(1) manpage). |
291 |
root |
1.11 |
|
292 |
root |
1.229 |
The event is simply the action string. This interface is going away in |
293 |

root |
1.144 |
Called just after the new window size has been calculated, but before |
298 |
root |
1.134 |
windows are actually being resized or hints are being set. If this hook |
299 |
root |
1.229 |
returns a true value, setting of the window hints is being skipped. |

|
303 |
|
|
Called on every X event received on the vt window (and possibly other |
304 |
|
|
windows). Should only be used as a last resort. Most event structure |
305 |
|
|
members are not passed. |

311 |
root |
1.45 |
=item on_focus_in $term |
312 |
|

Fatally aborts execution with the given error message (which should |
436 |
|
|
include a trailing newline). Avoid at all costs! The only time this |
437 |
|
|
is acceptable (and useful) is in the init hook, where it prevents the |

terminal from starting up. |

=item urxvt::warn $string |

root |
1.190 |
Calls C<rxvt_warn> with the given string which should include a trailing |
443 |
root |
1.1 |
newline. The module also overwrites the C<warn> builtin with a function |
444 |
|
|
that calls this function. |
445 |
|
|

446 |
|
|
Using this function has the advantage that its output ends up in the |

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

similar information for each screen cell. |

The following "macros" deal with changes in rendition sets. You should |
494 |
|
|
never just create a bitset, you should always modify an existing one, |
495 |
|
|
as they contain important information required for correct operation of |

a C<urxvt::term::extension> object. |
811 |
|
|
|
812 |

You can use these objects, which are passed to all callbacks to store any |

815 |

The methods (And data members) documented below can be called on extension |
816 |
|
|
objects, in addition to call methods documented for the <urxvt::term> |
817 |
|
|
class. |

=head2 The C<urxvt::anyevent> Class |
976 |
|
|
|
977 |
|
|
The sole purpose of this class is to deliver an interface to the |
978 |
|
|
C<AnyEvent> module - any module using it will work inside urxvt without |
979 |
root |
1.75 |
further programming. The only exception is that you cannot wait on |
980 |
root |
1.209 |
condition variables, but non-blocking condvar use is ok. |
981 |
|
|
|
982 |
|
|
In practical terms this means is that you cannot use blocking APIs, but |
983 |
|
|
the non-blocking variant should work. |

Creates a new terminal, very similar as if you had started it with system |

Works like the combination of the C<fork>/C<exec> builtins, which executes |
1187 |

|
("starts") programs in the background. This function takes care of setting |
1188 |

|
the user environment before exec'ing the command (e.g. C<PATH>) and should |

1228 |
|
|
Returns the current resource value associated with a given name and |
1229 |
|
|
optionally sets a new value. Setting values is most useful in the C<init> |
1230 |
|
|
hook. Unset resources are returned and accepted as C<undef>. |
1231 |
|
|
|
1232 |
|
|
The new value must be properly encoded to a suitable character encoding |
1233 |
|
|
before passing it to this method. Similarly, the returned value may need |
1234 |
|
|
to be converted from the used encoding to text. |
1235 |
|
|
|
1236 |
|
|
Resource names are as defined in F<src/rsinc.h>. Colours can be specified |
1237 |
|
|
as resource names of the form C<< color+<index> >>, e.g. C<color+5>. (will |
1238 |
|
|
likely change). |
1239 |
|
|
|
1240 |
|
|
Please note that resource strings will currently only be freed when the |
1241 |

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

Returns the X-Resource for the given pattern, excluding the program or |
1273 |
|
|
class name, i.e. C<< $term->x_resource ("boldFont") >> should return the |
1274 |

same value as used by this instance of rxvt-unicode. Returns C<undef> if no |

Extensions that define extra resource or command line arguments also need |
1278 |
|
|
to call this method to access their values. |
1279 |
|
|
|
1280 |
|
|
If the method is called on an extension object (basically, from an |
1281 |
|
|
extension), then the special prefix C<%.> will be replaced by the name of |
1282 |
sf-exg |
1.219 |
the extension and a dot, and the lone string C<%> will be replaced by the |
1283 |
root |
1.217 |
extension name itself. This makes it possible to code extensions so you |
1284 |
|
|
can rename them and get a new set of commandline switches and resources |
1285 |
|
|
without having to change the actual code. |
1286 |
|
|
|
1287 |
root |
1.79 |
This method should only be called during the C<on_start> hook, as there is |
1288 |

only one resource database per display, and later invocations might return |
1289 |
|
|
the wrong resources. |

Like C<x_resource>, above, but interprets the string value as a boolean |
1294 |

|
|
the resource or option isn't specified. |
1296 |
|
|
|
1297 |

Returns the text of the entire row with number C<$row_number>. Row C<< $term->top_row >> |
1644 |
|

is the topmost terminal line, row C<< $term->nrow-1 >> is the bottommost |
1645 |

is requested. |
1647 |
root |

1648 |
root |
1.13 |
If C<$new_text> is specified, it will replace characters in the current |
1649 |
|
|
line, starting at column C<$start_col> (default C<0>), which is useful |
1650 |
root |
1.18 |
to replace only parts of a line. The font index in the rendition will |
1651 |
root |
1.13 |
automatically be updated. |
1652 |
root |
1.12 |
|
1653 |
root |
1.124 |
C<$text> is in a special encoding: tabs and wide characters that use more |
1654 |
|
|
than one cell when displayed are padded with C<$urxvt::NOCHAR> (chr 65535) |
1655 |
root |
1.121 |
characters. Characters with combining characters and other characters that |
1656 |
ayin |
1.162 |
do not fit into the normal text encoding will be replaced with characters |
1657 |
root |
1.121 |
in the private use area. |
1658 |
root |
1.12 |
|
1659 |
|

You have to obey this encoding when changing text. The advantage is |
1660 |
|
|
that C<substr> and similar functions work on screen cells and not on |
1661 |
|
|
characters. |
1662 |
|
|
|
1663 |
|
|
The methods C<< $term->special_encode >> and C<< $term->special_decode >> |
1664 |
|
|
can be used to convert normal strings into this encoding and vice versa. |

|
|
|
1668 |
|
|
Like C<< $term->ROW_t >>, but returns an arrayref with rendition |
1669 |
|
|
bitsets. Rendition bitsets contain information about colour, font, font |
1670 |
|
|
styles and similar information. See also C<< $term->ROW_t >>. |
1671 |

1682 |

Returns true if the row is part of a multiple-row logical "line" (i.e. |
1685 |
