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. |

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

=head2 General API Considerations |
84 |
|
|
|
85 |
|
|
All objects (such as terminals, time watchers etc.) are typical |
86 |
|
|
reference-to-hash objects. The hash can be used to store anything you |
87 |
root |
1.7 |
like. All members starting with an underscore (such as C<_ptr> or |
88 |
root |
1.23 |
C<_hook>) are reserved for internal uses and B<MUST NOT> be accessed or |
89 |
root |
1.7 |
modified). |
90 |
root |
1.6 |
|
91 |
|
|
When objects are destroyed on the C++ side, the perl object hashes are |
92 |
|
|
emptied, so its best to store related objects such as time watchers and |
93 |
|
|
the like inside the terminal object so they get destroyed as soon as the |
94 |
|
|
terminal is destroyed. |
95 |
|
|
|
96 |
root |
1.33 |
Argument names also often indicate the type of a parameter. Here are some |
97 |
|
|
hints on what they mean: |

=item $text |
102 |
|
|
|
103 |
|
|
Rxvt-unicodes special way of encoding text, where one "unicode" character |
104 |
|
|
always represents one screen cell. See L<row_t> for a discussion of this format. |
105 |
|
|
|
106 |
|
|
=item $string |
107 |
|
|
|
108 |
|
|
A perl text string, with an emphasis on I<text>. It can store all unicode |
109 |
|
|
characters and is to be distinguished with text encoded in a specific |
110 |
|
|
encoding (often locale-specific) and binary data. |

|
|
|
112 |
|
|
=item $octets |
113 |
|
|

=head2 Hooks |
120 |
|
|
|
121 |
root |
1.43 |
The following subroutines can be declared in extension files, and will be |
122 |
root |
1.23 |
called whenever the relevant event happens. |
123 |
|
|
|
124 |
|
|
The first argument passed to them is an object private to each terminal |
125 |
root |
1.44 |
and extension package. You can call all C<urxvt::term> methods on it, but |
126 |
root |
1.23 |
its not a real C<urxvt::term> object. Instead, the real C<urxvt::term> |
127 |
|
|
object that is shared between all packages is stored in the C<term> |
128 |
root |
1.44 |
member. It is, however, blessed intot he package of the extension script, |
129 |
|
|
so for all practical purposes you can treat an extension script as a class. |
130 |
root |
1.1 |
|
131 |
|
|
All of them must return a boolean value. If it is true, then the event |
132 |
|
|
counts as being I<consumed>, and the invocation of other hooks is skipped, |
133 |
|
|
and the relevant action might not be carried out by the C++ code. |
134 |
|
|
|
135 |
|
|
When in doubt, return a false value (preferably C<()>). |

=item on_init $term |
140 |
|
|
|
141 |
|
|
Called after a new terminal object has been initialized, but before |
142 |
root |
1.36 |
windows are created or the command gets run. Most methods are unsafe to |
143 |
|
|
call or deliver senseless data, as terminal size and other characteristics |
144 |
|
|
have not yet been determined. You can safely query and change resources, |
145 |
|
|
though. |

|
=item on_reset $term |
148 |
|
|
|
149 |
|
|
Called after the screen is "reset" for any reason, such as resizing or |
150 |
|
|
control sequences. Here is where you can react on changes to size-related |
151 |
|
|
variables. |

|
|
|
153 |
|
|
=item on_start $term |
154 |
|
|
|
155 |

Called at the very end of initialisation of a new terminal, just before |
156 |
|
|
returning to the mainloop. |
157 |
|
|
|
158 |
|
|
=item on_sel_make $term, $eventtime |
159 |
|
|
|
160 |
|
|
Called whenever a selection has been made by the user, but before the |
161 |
|
|
selection text is copied, so changes to the beginning, end or type of the |
162 |
|
|
selection will be honored. |
163 |
|
|
|
164 |
|
|
Returning a true value aborts selection making by urxvt, in which case you |
165 |
|
|
have to make a selection yourself by calling C<< $term->selection_grab >>. |
166 |
|
|
|
167 |
|
|
=item on_sel_grab $term, $eventtime |
168 |
|
|
|
169 |
|
|
Called whenever a selection has been copied, but before the selection is |
170 |
|
|
requested from the server. The selection text can be queried and changed |
171 |
|
|
by calling C<< $term->selection >>. |
172 |
|
|
|
173 |
|
|
Returning a true value aborts selection grabbing. It will still be hilighted. |

|
175 |
root |
1.22 |
=item on_sel_extend $term |
176 |
|
|
|
177 |
|
|
Called whenever the user tries to extend the selection (e.g. with a double |
178 |
|
|
click) and is either supposed to return false (normal operation), or |
179 |
|
|
should extend the selection itelf and return true to suppress the built-in |
180 |
|
|
processing. |

185 |
|
|

Called whenever the view offset changes, i..e the user or program |
187 |
|
|
scrolls. Offset C<0> means display the normal terminal, positive values |
188 |
|
|
show this many lines of scrollback. |

|
190 |
|
|
=item on_scroll_back $term, $lines, $saved |
191 |
|
|
|
192 |
|
|
Called whenever lines scroll out of the terminal area into the scrollback |
193 |
|
|
buffer. C<$lines> is the number of lines scrolled out and may be larger |
194 |
|
|
than the scroll back buffer or the terminal. |
195 |
|
|
|
196 |
|
|
It is called before lines are scrolled out (so rows 0 .. min ($lines - 1, |
197 |
|
|
$nrow - 1) represent the lines to be scrolled out). C<$saved> is the total |
198 |
|
|
number of lines that will be in the scrollback buffer. |

|
200 |
|
|
=item on_tty_activity $term *NYI* |

root |
1.28 |
=item on_osc_seq $term, $string |
205 |
|

|
206 |
root |
1.29 |
Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC = |
207 |
|
|
operating system command) is processed. Cursor position and other state |
208 |
|
|
information is up-to-date when this happens. For interoperability, the |
209 |
|
|
string should start with the extension name and a colon, to distinguish |
210 |
|
|
it from commands for other extensions, and this might be enforced in the |
211 |
|
|
future. |
212 |
|
|
|
213 |
|
|
Be careful not ever to trust (in a security sense) the data you receive, |
214 |
|
|
as its source can not easily be controleld (e-mail content, messages from |
215 |
|
|
other users on the same system etc.). |

=item on_add_lines $term, $string |
218 |
|
|
|
219 |
|
|
Called whenever text is about to be output, with the text as argument. You |
220 |
|
|
can filter/change and output the text yourself by returning a true value |
221 |
|
|
and calling C<< $term->scr_add_lines >> yourself. Please note that this |
222 |
|
|
might be very slow, however, as your hook is called for B<all> text being |
223 |
|
|
output. |

225 |
root |
1.35 |
=item on_line_update $term, $row |
226 |
|
|
|
227 |
|
|
Called whenever a line was updated or changed. Can be used to filter |
228 |
|
|
screen output (e.g. underline urls or other useless stuff). Only lines |
229 |
|
|
that are being shown will be filtered, and, due to performance reasons, |
230 |
|
|
not always immediately. |
231 |
|
|
|
232 |
|
|
The row number is always the topmost row of the line if the line spans |
233 |
|
|
multiple rows. |
234 |
|
|
|
235 |
|
|
Please note that, if you change the line, then the hook might get called |
236 |
|
|
later with the already-modified line (e.g. if unrelated parts change), so |
237 |
|
|
you cannot just toggle rendition bits, but only set them. |

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

347 |
|
|
|
348 |
|
|
Rendition bitsets contain information about colour, font, font styles and |
349 |
|
|
similar information for each screen cell. |
350 |
|
|
|
351 |
|
|
The following "macros" deal with changes in rendition sets. You should |
352 |
|
|
never just create a bitset, you should always modify an existing one, |
353 |
|
|
as they contain important information required for correct operation of |
354 |
|
|
rxvt-unicode. |

Returns the current resource value associated with a given name and |
570 |
|
|
optionally sets a new value. Setting values is most useful in the C<init> |
571 |
|
|
hook. Unset resources are returned and accepted as C<undef>. |
572 |
|
|
|
573 |
|
|
The new value must be properly encoded to a suitable character encoding |
574 |
|
|
before passing it to this method. Similarly, the returned value may need |
575 |
|
|
to be converted from the used encoding to text. |
576 |
|
|
|
577 |
|
|
Resource names are as defined in F<src/rsinc.h>. Colours can be specified |
578 |

as resource names of the form C<< color+<index> >>, e.g. C<color+5>. (will |
579 |
|
|
likely change). |
580 |
|
|
|
581 |
|

Please note that resource strings will currently only be freed when the |

Write the given text string to the screen, as if output by the application |
735 |

running inside the terminal. It may not contain command sequences (escape |
736 |

codes), but is free to use line feeds, carriage returns and tabs. The |
737 |

string is a normal text string, not in locale-dependent encoding. |
738 |

Normally its not a good idea to use this function, as programs might be |
740 |

Returns the negative row number of the topmost line. Minimum value is |
801 |

C<0>, which displays the normal terminal contents. Larger values scroll |
802 |

this many lines into the scrollback buffer. |

root |
1.14 |

Requests a screen refresh. At the next opportunity, rxvt-unicode will |

compare the on-screen display with its stored representation. If they |
808 |
|
|
differ, it redraws the differences. |
809 |
|

810 |
|
|
Used after changing terminal contents to display them. |
811 |

=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
813 |
root |
1.12 |
|
814 |
|
|
Returns the text of the entire row with number C<$row_number>. Row C<0> |
815 |
|
|
is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost |
816 |
|
|
terminal line. The scrollback buffer starts at line C<-1> and extends to |
817 |
root |
1.24 |
line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line |
818 |
|
|
is requested. |
819 |
root |
1.12 |
|
820 |
root |
1.13 |
If C<$new_text> is specified, it will replace characters in the current |
821 |
|
|
line, starting at column C<$start_col> (default C<0>), which is useful |
822 |
root |
1.18 |
to replace only parts of a line. The font index in the rendition will |
823 |
root |
1.13 |
automatically be updated. |
824 |
root |
1.12 |
|
825 |
|
|
C<$text> is in a special encoding: tabs and wide characters that use more |
826 |
|
|
than one cell when displayed are padded with urxvt::NOCHAR characters |
827 |
|
|
(C<chr 65535>). Characters with combining characters and other characters |
828 |
|
|
that do not fit into the normal tetx encoding will be replaced with |
829 |
|
|
characters in the private use area. |
830 |
|
|
|
831 |
|
|
You have to obey this encoding when changing text. The advantage is |
832 |
|
|
that C<substr> and similar functions work on screen cells and not on |
833 |
|
|
characters. |
834 |
|
|
|
835 |
|
|
The methods C<< $term->special_encode >> and C<< $term->special_decode >> |
836 |
|
|
can be used to convert normal strings into this encoding and vice versa. |
837 |
|

=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
839 |
|
|
|
840 |
|
|
Like C<< $term->ROW_t >>, but returns an arrayref with rendition |
841 |
|
|
bitsets. Rendition bitsets contain information about colour, font, font |
842 |
|
|
styles and similar information. See also C<< $term->ROW_t >>. |
843 |
|
|
|
844 |

When setting rendition, the font mask will be ignored. |

Returns the number of screen cells that are in use ("the line |
851 |
|
|
length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the |
852 |
|
|
line is joined with the following one. |
853 |

854 |
|
|
=item $bool = $term->is_longer ($row_number) |
855 |

|
|
856 |
|
|
Returns true if the row is part of a multiple-row logical "line" (i.e. |
857 |
|
|
joined with the following row), which means all characters are in use |
858 |
|
|
and it is continued on the next row (and possibly a continuation of the |
859 |

previous row(s)). |

Create a new timer object in started state. It is scheduled to fire |
1044 |
|
|
immediately. |
1045 |

|
|
=item $timer = $timer->cb (sub { my ($timer) = @_; ... }) |
1047 |
|
|
|
1048 |

|
|
1050 |
|
|
=item $tstamp = $timer->at |
1051 |
|
|
|
1052 |
|
|
Return the time this watcher will fire next. |
1053 |

|
1054 |
|
|
=item $timer = $timer->set ($tstamp) |
1055 |
|

|
|
Normally (and when C<$interval> is C<0>), the timer will automatically |
1061 |
|
|
stop after it has fired once. If C<$interval> is non-zero, then the timer |
1062 |
|
|
is automatically rescheduled at the given intervals. |
