Intelligent selection. This extension tries to be more intelligent when |

the user extends selections (double\-click). Right now, it tries to select |
| 179 |
urls and complete shell-quoted arguments, which is very convenient, too, |

.Sh "General \s-1API\s0 Considerations" |
| 219 |
.IX Subsection "General API Considerations" |
| 220 |
All objects (such as terminals, time watchers etc.) are typical |
| 221 |
reference-to-hash objects. The hash can be used to store anything you |
| 222 |
like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or |
| 223 |
\&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or |
| 224 |
modified). |
| 225 |
.PP |
| 226 |
When objects are destroyed on the \*(C+ side, the perl object hashes are |
| 227 |
emptied, so its best to store related objects such as time watchers and |
| 228 |
the like inside the terminal object so they get destroyed as soon as the |
| 229 |
terminal is destroyed. |
| 230 |
.PP |
| 231 |
Argument names also often indicate the type of a parameter. Here are some |
| 232 |
hints on what they mean: |
| 233 |
.IP "$text" 4 |
| 234 |
.IX Item "$text" |
| 235 |
Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character |
| 236 |
always represents one screen cell. See row_t for a discussion of this format. |
| 237 |
.IP "$string" 4 |
| 238 |
.IX Item "$string" |
| 239 |
A perl text string, with an emphasis on \fItext\fR. It can store all unicode |
| 240 |
characters and is to be distinguished with text encoded in a specific |
| 241 |
encoding (often locale\-specific) and binary data. |
| 242 |
.IP "$octets" 4 |
| 243 |
.IX Item "$octets" |
| 244 |
Either binary data or \- more common \- a text string encoded in a |
| 245 |
locale-specific way. |
| 246 |
.Sh "Hooks" |
| 247 |
.IX Subsection "Hooks" |
| 248 |
The following subroutines can be declared in extension files, and will be |
| 249 |
called whenever the relevant event happens. |
| 250 |
.PP |
| 251 |
The first argument passed to them is an object private to each terminal |
| 252 |
and extension package. You can call all \f(CW\*(C`urxvt::term\*(C'\fR methods on it, but |
| 253 |
its not a real \f(CW\*(C`urxvt::term\*(C'\fR object. Instead, the real \f(CW\*(C`urxvt::term\*(C'\fR |
| 254 |
object that is shared between all packages is stored in the \f(CW\*(C`term\*(C'\fR |
| 255 |
member. It is, however, blessed intot he package of the extension script, |
| 256 |
so for all practical purposes you can treat an extension script as a class. |
| 257 |
.PP |
| 258 |
All of them must return a boolean value. If it is true, then the event |
| 259 |
counts as being \fIconsumed\fR, and the invocation of other hooks is skipped, |
| 260 |
and the relevant action might not be carried out by the \*(C+ code. |
| 261 |
.PP |
| 262 |
When in doubt, return a false value (preferably \f(CW\*(C`()\*(C'\fR). |
| 263 |
.ie n .IP "on_init $term" 4 |
| 264 |
.el .IP "on_init \f(CW$term\fR" 4 |
| 265 |
.IX Item "on_init $term" |
| 266 |
Called after a new terminal object has been initialized, but before |
| 267 |
windows are created or the command gets run. Most methods are unsafe to |
| 268 |
call or deliver senseless data, as terminal size and other characteristics |
| 269 |
have not yet been determined. You can safely query and change resources, |
| 270 |
though. |
| 271 |
.ie n .IP "on_reset $term" 4 |
| 272 |
.el .IP "on_reset \f(CW$term\fR" 4 |
| 273 |
.IX Item "on_reset $term" |
| 274 |
Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or |
| 275 |
control sequences. Here is where you can react on changes to size-related |
| 276 |
variables. |
| 277 |
.ie n .IP "on_start $term" 4 |
| 278 |
.el .IP "on_start \f(CW$term\fR" 4 |
| 279 |
.IX Item "on_start $term" |
| 280 |
Called at the very end of initialisation of a new terminal, just before |
| 281 |
returning to the mainloop. |
| 282 |
.ie n .IP "on_sel_make $term\fR, \f(CW$eventtime" 4 |
| 283 |
.el .IP "on_sel_make \f(CW$term\fR, \f(CW$eventtime\fR" 4 |
| 284 |
.IX Item "on_sel_make $term, $eventtime" |
| 285 |
Called whenever a selection has been made by the user, but before the |
| 286 |
selection text is copied, so changes to the beginning, end or type of the |
| 287 |
selection will be honored. |
| 288 |
.Sp |
| 289 |
Returning a true value aborts selection making by urxvt, in which case you |
| 290 |
have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR. |
| 291 |
.ie n .IP "on_sel_grab $term\fR, \f(CW$eventtime" 4 |
| 292 |

| 293 |
.IX Item "on_sel_grab $term, $eventtime" |
| 294 |
Called whenever a selection has been copied, but before the selection is |
| 295 |
requested from the server. The selection text can be queried and changed |
| 296 |
by calling \f(CW\*(C`$term\->selection\*(C'\fR. |
| 297 |
.Sp |
| 298 |
Returning a true value aborts selection grabbing. It will still be hilighted. |
| 299 |
.ie n .IP "on_sel_extend $term" 4 |
| 300 |
.el .IP "on_sel_extend \f(CW$term\fR" 4 |
| 301 |
.IX Item "on_sel_extend $term" |
| 302 |
Called whenever the user tries to extend the selection (e.g. with a double |
| 303 |
click) and is either supposed to return false (normal operation), or |
| 304 |
should extend the selection itelf and return true to suppress the built-in |
| 305 |
processing. |
| 306 |
.Sp |
| 307 |
See the \fIselection\fR example extension. |

.el .IP "on_view_change \f(CW$term\fR, \f(CW$offset\fR" 4 |
| 310 |
.IX Item "on_view_change $term, $offset" |
| 311 |
Called whenever the view offset changes, i..e the user or program |
| 312 |
scrolls. Offset \f(CW0\fR means display the normal terminal, positive values |
| 313 |
show this many lines of scrollback. |
| 314 |

| 316 |
.IX Item "on_scroll_back $term, $lines, $saved" |
| 317 |
Called whenever lines scroll out of the terminal area into the scrollback |
| 318 |
buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger |
| 319 |
than the scroll back buffer or the terminal. |
| 320 |
.Sp |
| 321 |
It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1, |
| 322 |
\&\f(CW$nrow\fR \- 1) represent the lines to be scrolled out). \f(CW$saved\fR is the total |
| 323 |
number of lines that will be in the scrollback buffer. |
| 324 |
.ie n .IP "on_osc_seq $term\fR, \f(CW$string" 4 |
| 325 |
.el .IP "on_osc_seq \f(CW$term\fR, \f(CW$string\fR" 4 |
| 326 |
.IX Item "on_osc_seq $term, $string" |
| 327 |
Called whenever the \fB\s-1ESC\s0 ] 777 ; string \s-1ST\s0\fR command sequence (\s-1OSC\s0 = |
| 328 |
operating system command) is processed. Cursor position and other state |
| 329 |
information is up-to-date when this happens. For interoperability, the |
| 330 |
string should start with the extension name and a colon, to distinguish |
| 331 |
it from commands for other extensions, and this might be enforced in the |
| 332 |
future. |
| 333 |
.Sp |
| 334 |
Be careful not ever to trust (in a security sense) the data you receive, |
| 335 |
as its source can not easily be controleld (e\-mail content, messages from |

| 339 |
.IX Item "on_add_lines $term, $string" |
| 340 |
Called whenever text is about to be output, with the text as argument. You |
| 341 |
can filter/change and output the text yourself by returning a true value |
| 342 |
and calling \f(CW\*(C`$term\->scr_add_lines\*(C'\fR yourself. Please note that this |
| 343 |
might be very slow, however, as your hook is called for \fBall\fR text being |
| 344 |
output. |

.IX Item "on_line_update $term, $row" |
| 348 |
Called whenever a line was updated or changed. Can be used to filter |
| 349 |
screen output (e.g. underline urls or other useless stuff). Only lines |

Create a new timer object in started state. It is scheduled to fire |
| 928 |
immediately. |

Set the callback to be called when the timer triggers. |

Normally (and when \f(CW$interval\fR is \f(CW0\fR), the timer will automatically |
| 945 |
stop after it has fired once. If \f(CW$interval\fR is non\-zero, then the timer |
| 946 |
is automatically rescheduled at the given intervals. |

Set the event trigger time to \f(CW$tstamp\fR and start the timer. |
