43 | |

|
44 | (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>. |
|

71 | |
|
|
72 | =item searchable-scrollback<hotkey> (enabled by default) |
|
|
73 | |
|
|
74 | 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 | history, C<enter> leaves search mode at the current position and C<escape> |
|

81 | returns to the original position. |

|
|
88 | |
|
|
89 | Uses per-line display filtering (C<on_line_update>) to underline urls and |

|
90 | make them clickable. When middle-clicked, the program specified in the |
|
|
91 | resource C<urlLauncher> (default C<x-www-browser>) will be started. |
|
|
92 | |
|
|
93 | =item block-graphics-to-ascii |
|
|
94 | |
|
|
95 | A not very useful example of filtering all text output to the terminal, |
|

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. |

170 | to overwrite time-critical hooks only temporarily. |

262 | future. |
|
|
263 | |
|
|
264 | Be careful not ever to trust (in a security sense) the data you receive, |

|
268 | =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. |

276 | =item on_tt_write $term, $octets |

|
|
281 | =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. |

441 | The following "macros" deal with changes in rendition sets. You should |

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

708 | 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 |

710 | work. |

1133 | Returns the negative row number of the topmost line. Minimum value is |

1134 | C<0>, which displays the normal terminal contents. Larger values scroll |
|
|
1135 | this many lines into the scrollback buffer. |
|
|
1136 | |
|
|
1137 | =item $term->want_refresh |
|
|
1138 | |
|
|
1139 | Requests a screen refresh. At the next opportunity, rxvt-unicode will |
|
|
1140 | compare the on-screen display with its stored representation. If they |
|
|
1141 | differ, it redraws the differences. |
|
|
1142 | |
|
|
1143 | Used after changing terminal contents to display them. |
|
|
1144 | |
|
|
1145 | =item $text = $term->ROW_t ($row_number[, $new_text[, $start_col]]) |
|
|
1146 | |
|
|
1147 | Returns the text of the entire row with number C<$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 | line C<< -$term->nsaved >>. Nothing will be returned if a nonexistent line |
|
|
1151 | is requested. |
|
|
1152 | |
|
|
1153 | If C<$new_text> is specified, it will replace characters in the current |
|
|
1154 | line, starting at column C<$start_col> (default C<0>), which is useful |
|
|
1155 | to replace only parts of a line. The font index in the rendition will |
|
|
1156 | automatically be updated. |
|
|
1157 | |
|
|
1158 | C<$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. |
|
|
1170 | |
|
|
1171 | =item $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]]) |
|
|
1172 | |
|
|
1173 | 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 | |
|
|
1177 | When setting rendition, the font mask will be ignored. |
|
|
1178 | |
|
|
1179 | See the section on RENDITION, above. |

|
1180 | |
|
|
1181 | =item $length = $term->ROW_l ($row_number[, $new_length]) |
|
|
1182 | |
|
|
1183 | Returns the number of screen cells that are in use ("the line |
|
|
1184 | length"). Unlike the urxvt core, this returns C<< $term->ncol >> if the |
|
|
1185 | line is joined with the following one. |
|
|
1186 | |
|
|
1187 | =item $bool = $term->is_longer ($row_number) |
|
|
1188 | |
|
|
1189 | 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 | and it is continued on the next row (and possibly a continuation of the |
|
|
1192 | previous row(s)). |
|
|
1193 | |
|
|
1194 | =item $line = $term->line ($row_number) |
|
|
1195 | |
|
|
1196 | Create and return a new C<urxvt::line> object that stores information |
|
|
1197 | about the logical line that row C<$row_number> is part of. It supports the |
