33This section describes the extensiosn delivered with this version. You can
34find them in F<@@RXVT_LIBDIR@@/urxvt/perl/>.

42=item selection (enabled by default)
43
44Intelligent selection. This extension tries to be more intelligent when
45the user extends selections (double-click). Right now, it tries to select
46urls and complete shell-quoted arguments, which is very convenient, too,
47if your F<ls> supports C<--quoting-style=shell>.

75
76A not very useful example of filtering all text output to the terminal,
77by replacing all line-drawing characters (U+2500 .. U+259F) by a
78similar-looking ascii character.

110
111=item $string
112
113A perl text string, with an emphasis on I<text>. It can store all unicode
114characters and is to be distinguished with text encoded in a specific
115encoding (often locale-specific) and binary data.

129The first argument passed to them is an object private to each terminal
130and extension package. You can call all C<urxvt::term> methods on it, but
131its not a real C<urxvt::term> object. Instead, the real C<urxvt::term>
132object that is shared between all packages is stored in the C<term>
133member. It is, however, blessed intot he package of the extension script,
134so for all practical purposes you can treat an extension script as a class.

55Called after a new terminal object has been initialized, but before 146Called after a new terminal object has been initialized, but before
56windows are created or the command gets run. 147windows are created or the command gets run. Most methods are unsafe to
148call or deliver senseless data, as terminal size and other characteristics
149have not yet been determined. You can safely query and change resources,
150though.

113 206
114Called whenever the program(s) running in the urxvt window send output. 207Called whenever the program(s) running in the urxvt window send output.
208
209=item on_osc_seq $term, $string
210
211Called whenever the B<ESC ] 777 ; string ST> command sequence (OSC =
212operating system command) is processed. Cursor position and other state
213information is up-to-date when this happens. For interoperability, the
214string should start with the extension name and a colon, to distinguish
215it from commands for other extensions, and this might be enforced in the
216future.
217
218Be careful not ever to trust (in a security sense) the data you receive,
219as its source can not easily be controleld (e-mail content, messages from
220other users on the same system etc.).
221
222=item on_add_lines $term, $string
223
224Called whenever text is about to be output, with the text as argument. You
225can filter/change and output the text yourself by returning a true value
226and calling C<< $term->scr_add_lines >> yourself. Please note that this
227might be very slow, however, as your hook is called for B<all> text being
228output.
229
230=item on_line_update $term, $row
231
232Called whenever a line was updated or changed. Can be used to filter
233screen output (e.g. underline urls or other useless stuff). Only lines
234that are being shown will be filtered, and, due to performance reasons,
235not always immediately.
236
237The row number is always the topmost row of the line if the line spans
238multiple rows.
239
240Please note that, if you change the line, then the hook might get called
241later with the already-modified line (e.g. if unrelated parts change), so
242you cannot just toggle rendition bits, but only set them.
115 243
116=item on_refresh_begin $term 244=item on_refresh_begin $term
117 245
118Called just before the screen gets redrawn. Can be used for overlay 246Called just before the screen gets redrawn. Can be used for overlay
119or similar effects by modify terminal contents in refresh_begin, and 247or similar effects by modify terminal contents in refresh_begin, and

124 252
125Called just after the screen gets redrawn. See C<on_refresh_begin>. 253Called just after the screen gets redrawn. See C<on_refresh_begin>.
126 254
255=item on_keyboard_command $term, $string
256
257Called whenever the user presses a key combination that has a
258C<perl:string> action bound to it (see description of the B<keysym>
259resource in the @@RXVT_NAME@@(1) manpage).
260
261=item on_focus_in $term
262
263Called whenever the window gets the keyboard focus, before rxvt-unicode
264does focus in processing.
265
266=item on_focus_out $term
267
268Called wheneever the window loses keyboard focus, before rxvt-unicode does
269focus out processing.

284
285Called whenever the corresponding X event is received for the terminal If
286the hook returns true, then the even will be ignored by rxvt-unicode.
287
288The event is a hash with most values as named by Xlib (see the XEvent
289manpage), with the additional members C<row> and C<col>, which are the row
290and column under the mouse cursor.

352
353Rendition bitsets contain information about colour, font, font styles and
354similar information for each screen cell.
355
356The following "macros" deal with changes in rendition sets. You should
357never just create a bitset, you should always modify an existing one,
358as they contain important information required for correct operation of
359rxvt-unicode.

363=item $rend = urxvt::DEFAULT_RSTYLE
364
365Returns the default rendition, as used when the terminal is starting up or

595further work. The only exception is that you cannot wait on condition
596variables, but non-blocking condvar use is ok. What this means is that you
597cannot use blocking APIs, but the non-blocking variant should work.

795text in rxvt-unicode's special encoding and an array of rendition values
796at a specific position inside the overlay.

383 847
848=item $term->scr_add_lines ($string)
849
850Write the given text string to the screen, as if output by the application
851running inside the terminal. It may not contain command sequences (escape
852codes), but is free to use line feeds, carriage returns and tabs. The
853string is a normal text string, not in locale-dependent encoding.
854
855Normally its not a good idea to use this function, as programs might be
856confused by changes in cursor position or scrolling. Its useful inside a
857C<on_add_lines> hook, though.
858
859=item $term->cmd_parse ($octets)
860
861Similar to C<scr_add_lines>, but the argument must be in the

901=item $lines_in_scrollback = $term->nsaved
902
903Return various integers describing terminal characteristics.

905=item $modifiermask = $term->ModLevel3Mask
906
907=item $modifiermask = $term->ModMetaMask
908
909=item $modifiermask = $term->ModNumLockMask
910
911Return the modifier masks corresponding to the "ISO Level 3 Shift" (often
912AltGr), the meta key (often Alt) and the num lock key, if applicable.
913
914=item $view_start = $term->view_start ([$newvalue])
915
916Returns the negative row number of the topmost line. Minimum value is
917C<0>, which displays the normal terminal contents. Larger values scroll
918this many lines into the scrollback buffer.
919
920=item $term->want_refresh
921
922Requests a screen refresh. At the next opportunity, rxvt-unicode will
923compare the on-screen display with its stored representation. If they
924differ, it redraws the differences.
925
926Used after changing terminal contents to display them.
927
928=item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
929
930Returns the text of the entire row with number C<$row_number>. Row C<0>
931is the topmost terminal line, row C<< $term->$ncol-1 >> is the bottommost
932terminal line. The scrollback buffer starts at line C<-1> and extends to
933line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line
934is requested.
935
936If C<$new_text> is specified, it will replace characters in the current
937line, starting at column C<$start_col> (default C<0>), which is useful
938to replace only parts of a line. The font index in the rendition will
939automatically be updated.
940
941C<$text> is in a special encoding: tabs and wide characters that use more
942than one cell when displayed are padded with urxvt::NOCHAR characters
943(C<chr 65535>). Characters with combining characters and other characters
944that do not fit into the normal tetx encoding will be replaced with
945characters in the private use area.
946
947You have to obey this encoding when changing text. The advantage is
948that C<substr> and similar functions work on screen cells and not on
949characters.
950
951The methods C<< $term->special_encode >> and C<< $term->special_decode >>
952can be used to convert normal strings into this encoding and vice versa.
953
954=item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
955
956Like C<< $term->ROW_t >>, but returns an arrayref with rendition
957bitsets. Rendition bitsets contain information about colour, font, font
958styles and similar information. See also C<< $term->ROW_t >>.
959
960When setting rendition, the font mask will be ignored.
961
962See the section on RENDITION, above.
963
964=item $length = $term->ROW_l ($row_number[, $new_length])
965
966Returns the number of screen cells that are in use ("the line
967length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the
968line is joined with the following one.
969
970=item $bool = $term->is_longer ($row_number)
971
972Returns true if the row is part of a multiple-row logical "line" (i.e.
973joined with the following row), which means all characters are in use
974and it is continued on the next row (and possibly a continuation of the
975previous row(s)).
976
977=item $line = $term->line ($row_number)
978
979Create and return a new C<urxvt::line> object that stores information
980about the logical line that row C<$row_number> is part of. It supports the
981following methods:
982
983=over 4
984
985=item $text = $line->t ([$new_text])
986
987Returns or replaces the full text of the line, similar to C<ROW_t>
988
989=item $rend = $line->r ([$new_rend])
990
991Returns or replaces the full rendition array of the line, similar to C<ROW_r>
992
993=item $length = $line->l
994
995Returns the length of the line in cells, similar to C<ROW_l>.
996
997=item $rownum = $line->beg
998
999=item $rownum = $line->end
1000
1001Return the row number of the first/last row of the line, respectively.
1002
1003=item $offset = $line->offset_of ($row, $col)
1004
1005Returns the character offset of the given row|col pair within the logical
1006line.
1007
1008=item ($row, $col) = $line->coord_of ($offset)
1009
