.IX Item "selection (enabled by default)" |
| 183 |
(More) intelligent selection. This extension tries to be more intelligent |
| 184 |
when the user extends selections (double\-click and further clicks). Right |
| 185 |
now, it tries to select words, urls and complete shell-quoted |
| 186 |
arguments, which is very convenient, too, if your \fIls\fR supports |
| 187 |
\&\f(CW\*(C`\-\-quoting\-style=shell\*(C'\fR. |
| 188 |
.Sp |
| 189 |
A double-click usually selects the word under the cursor, further clicks |
| 190 |
will enlarge the selection. |
| 191 |
.Sp |
| 192 |
The selection works by trying to match a number of regexes and displaying |
| 193 |
them in increasing order of length. You can add your own regexes by |
| 194 |
specifying resources of the form: |
| 195 |
.Sp |
| 196 |
.Vb 3 |
| 197 |
\& URxvt.selection.pattern-0: perl-regex |
| 198 |
\& URxvt.selection.pattern-1: perl-regex |
| 199 |
\& ... |
| 200 |
.Ve |
| 201 |
.Sp |
| 202 |
The index number (0, 1...) must not have any holes, and each regex must |
| 203 |
contain at least one pair of capturing parentheses, which will be used for |
| 204 |
the match. For example, the followign adds a regex that matches everything |
| 205 |
between two vertical bars: |
| 206 |
.Sp |
| 207 |
.Vb 1 |
| 208 |
\& URxvt.selection.pattern-0: \e\e|([^|]+)\e\e| |
| 209 |
.Ve |

You can look at the source of the selection extension to see more |
| 212 |
interesting uses, such as parsing a line from beginning to end. |

.IP "option-popup (enabled by default)" 4 |
| 227 |
.IX Item "option-popup (enabled by default)" |
| 228 |
Binds a popup menu to Ctrl\-Button2 that lets you toggle (some) options at |
| 229 |
runtime. |
| 230 |
.IP "selection-popup (enabled by default)" 4 |
| 231 |
.IX Item "selection-popup (enabled by default)" |
| 232 |
Binds a popup menu to Ctrl\-Button3 that lets you convert the selection |
| 233 |
text into various other formats/action (such as uri unescaping, perl |
| 234 |
evalution, web-browser starting etc.), depending on content. |
| 235 |
.Sp |
| 236 |
Other extensions can extend this popup menu by pushing a code reference |
| 237 |
onto \f(CW\*(C`@{ $term\-\*(C'\fR{selection_popup_hook} }>, that is called whenever the |
| 238 |
popup is displayed. |
| 239 |
.Sp |
| 240 |
It's sole argument is the popup menu, which can be modified. The selection |
| 241 |
is in \f(CW$_\fR, which can be used to decide wether to add something or not. |
| 242 |
It should either return nothing or a string and a code reference. The |
| 243 |
string will be used as button text and the code reference will be called |
| 244 |
when the button gets activated and should transform \f(CW$_\fR. |
| 245 |
.Sp |
| 246 |
The following will add an entry \f(CW\*(C`a to b\*(C'\fR that transforms all \f(CW\*(C`a\*(C'\fRs in |
| 247 |
the selection to \f(CW\*(C`b\*(C'\fRs, but only if the selection currently contains any |
| 248 |
\&\f(CW\*(C`a\*(C'\fRs: |

.IP "searchable\-scrollback<hotkey> (enabled by default)" 4 |
| 257 |
.IX Item "searchable-scrollback<hotkey> (enabled by default)" |
| 258 |
Adds regex search functionality to the scrollback buffer, triggered |
| 259 |
by a hotkey (default: \f(CW\*(C`M\-s\*(C'\fR). While in search mode, normal terminal |
| 260 |
input/output is suspended and a regex is displayed at the bottom of the |
| 261 |
screen. |
| 262 |
.Sp |
| 263 |
Inputting characters appends them to the regex and continues incremental |
| 264 |
search. \f(CW\*(C`BackSpace\*(C'\fR removes a character from the regex, \f(CW\*(C`Up\*(C'\fR and \f(CW\*(C`Down\*(C'\fR |
| 265 |
search upwards/downwards in the scrollback buffer, \f(CW\*(C`End\*(C'\fR jumps to the |
| 266 |
bottom. \f(CW\*(C`Escape\*(C'\fR leaves search mode and returns to the point where search |
| 267 |
was started, while \f(CW\*(C`Enter\*(C'\fR or \f(CW\*(C`Return\*(C'\fR stay at the current position and |
| 268 |
additionally stores the first match in the current line into the primary |
| 269 |
selection. |
| 270 |
.IP "selection-autotransform" 4 |
| 271 |
.IX Item "selection-autotransform" |
| 272 |
This selection allows you to do automatic transforms on a selection |
| 273 |
whenever a selection is made. |
| 274 |
.Sp |
| 275 |
It works by specifying perl snippets (most useful is a single \f(CW\*(C`s///\*(C'\fR |
| 276 |
operator) that modify \f(CW$_\fR as resources: |
| 277 |
.Sp |
| 278 |
.Vb 3 |
| 279 |
\& URxvt.selection-autotransform.0: transform |
| 280 |
\& URxvt.selection-autotransform.1: transform |
| 281 |
\& ... |
| 282 |
.Ve |
| 283 |
.Sp |
| 284 |
For example, the following will transform selections of the form |
| 285 |
\&\f(CW\*(C`filename:number\*(C'\fR, often seen in compiler messages, into \f(CW\*(C`vi +$filename |
| 286 |
$word\*(C'\fR: |
| 287 |
.Sp |
| 288 |
.Vb 1 |
| 289 |
\& URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\e\ed+):?$/vi +$2 \e\eQ$1\e\eE\e\ex0d/ |
| 290 |
.Ve |
| 291 |
.Sp |
| 292 |
And this example matches the same,but replaces it with vi-commands you can |
| 293 |
paste directly into your (vi :) editor: |
| 294 |
.Sp |
| 295 |
.Vb 1 |
| 296 |
\& URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\e\ed+):?$/:e \e\eQ$1\e\eE\e\ex0d:$2\e\ex0d/ |
| 297 |
.Ve |
| 298 |
.Sp |
| 299 |
Of course, this can be modified to suit your needs and your editor :) |
| 300 |
.Sp |
| 301 |
To expand the example above to typical perl error messages (\*(L"\s-1XXX\s0 at |
| 302 |
\&\s-1FILENAME\s0 line \s-1YYY\s0.\*(R"), you need a slightly more elaborate solution: |
| 303 |
.Sp |
| 304 |
.Vb 2 |
| 305 |
\& URxvt.selection.pattern-0: ( at .*? line \e\ed+[,.]) |
| 306 |
\& URxvt.selection-autotransform.0: s/^ at (.*?) line (\e\ed+)[,.]$/:e \e\eQ$1\eE\e\ex0d:$2\e\ex0d/ |
| 307 |
.Ve |
| 308 |
.Sp |
| 309 |
The first line tells the selection code to treat the unchanging part of |
| 310 |
every error message as a selection pattern, and the second line transforms |
| 311 |
the message into vi commands to load the file. |
| 312 |
.IP "tabbed" 4 |
| 313 |
.IX Item "tabbed" |
| 314 |
This transforms the terminal into a tabbar with additional terminals, that |
| 315 |
is, it implements what is commonly refered to as \*(L"tabbed terminal\*(R". The topmost line |
| 316 |
displays a \*(L"[\s-1NEW\s0]\*(R" button, which, when clicked, will add a new tab, followed by one |
| 317 |
button per tab. |
| 318 |
.Sp |
| 319 |
Clicking a button will activate that tab. Pressing Shift-Left and |
| 320 |
Shift-Right will switch to the tab left or right of the current one. |
| 321 |
.IP "mark-urls" 4 |
| 322 |
.IX Item "mark-urls" |
| 323 |
Uses per-line display filtering (\f(CW\*(C`on_line_update\*(C'\fR) to underline urls and |
| 324 |
make them clickable. When middle\-clicked, the program specified in the |
| 325 |
resource \f(CW\*(C`urlLauncher\*(C'\fR (default \f(CW\*(C`x\-www\-browser\*(C'\fR) will be started with |
| 326 |
the \s-1URL\s0 as first argument. |
| 327 |
.IP "automove-background" 4 |
| 328 |
.IX Item "automove-background" |
| 329 |
This is basically a one-line extension that dynamically changes the background pixmap offset |
| 330 |
to the window position, in effect creating the same effect as pseudo transparency with |
| 331 |
a custom pixmap. No scaling is supported in this mode. Exmaple: |

.IP "block-graphics-to-ascii" 4 |
| 337 |
.IX Item "block-graphics-to-ascii" |
| 338 |
A not very useful example of filtering all text output to the terminal, |
| 339 |
by replacing all line-drawing characters (U+2500 .. U+259F) by a |
| 340 |
similar-looking ascii character. |
| 341 |
.IP "digital-clock" 4 |
| 342 |

| 343 |
Displays a digital clock using the built-in overlay. |
| 344 |
.IP "example-refresh-hooks" 4 |
| 345 |
.IX Item "example-refresh-hooks" |
| 346 |
Displays a very simple digital clock in the upper right corner of the |
| 347 |
window. Illustrates overwriting the refresh callbacks to create your own |
| 348 |
overlays or changes. |
| 349 |
.IP "selection-pastebin" 4 |
| 350 |
.IX Item "selection-pastebin" |
| 351 |
This is a little rarely useful extension that Uploads the selection as |
| 352 |
textfile to a remote site (or does other things). (The implementation is |
| 353 |
not currently secure for use in a multiuser environment as it writes to |
| 354 |
\&\fI/tmp\fR directly.). |
| 355 |
.Sp |
| 356 |
It listens to the \f(CW\*(C`selection\-pastebin:remote\-pastebin\*(C'\fR keyboard command, |
| 357 |
i.e. |
| 358 |
.Sp |
| 359 |

| 387 |
All objects (such as terminals, time watchers etc.) are typical |
| 388 |
reference-to-hash objects. The hash can be used to store anything you |
| 389 |
like. All members starting with an underscore (such as \f(CW\*(C`_ptr\*(C'\fR or |
| 390 |
\&\f(CW\*(C`_hook\*(C'\fR) are reserved for internal uses and \fB\s-1MUST\s0 \s-1NOT\s0\fR be accessed or |
| 391 |
modified). |
| 392 |
.PP |
| 393 |
When objects are destroyed on the \*(C+ side, the perl object hashes are |
| 394 |
emptied, so its best to store related objects such as time watchers and |
| 395 |
the like inside the terminal object so they get destroyed as soon as the |
| 396 |
terminal is destroyed. |

.PP |
| 398 |
Argument names also often indicate the type of a parameter. Here are some |
| 399 |
hints on what they mean: |
| 400 |
.IP "$text" 4 |
| 401 |
.IX Item "$text" |
| 402 |
Rxvt-unicodes special way of encoding text, where one \*(L"unicode\*(R" character |
| 403 |
always represents one screen cell. See ROW_t for a discussion of this format. |
| 404 |
.IP "$string" 4 |
| 405 |
.IX Item "$string" |
| 406 |
A perl text string, with an emphasis on \fItext\fR. It can store all unicode |
| 407 |
characters and is to be distinguished with text encoded in a specific |
| 408 |
encoding (often locale\-specific) and binary data. |
| 409 |
.IP "$octets" 4 |
| 410 |
.IX Item "$octets" |
| 411 |
Either binary data or \- more common \- a text string encoded in a |
| 412 |
locale-specific way. |

.Sh "Extension Objects" |
| 414 |
.IX Subsection "Extension Objects" |
| 415 |
Very perl extension is a perl class. A separate perl object is created |
| 416 |
for each terminal and each extension and passed as the first parameter to |
| 417 |
hooks. So extensions can use their \f(CW$self\fR object without having to think |
| 418 |
about other extensions, with the exception of methods and members that |
| 419 |
begin with an underscore character \f(CW\*(C`_\*(C'\fR: these are reserved for internal |
| 420 |
use. |
| 421 |
.PP |
| 422 |
Although it isn't a \f(CW\*(C`urxvt::term\*(C'\fR object, you can call all methods of the |
| 423 |
\&\f(CW\*(C`urxvt::term\*(C'\fR class on this object. |
| 424 |
.PP |
| 425 |

.ie n .IP "$urxvt_term = $self\->{term}" 4 |
| 427 |
.el .IP "$urxvt_term = \f(CW$self\fR\->{term}" 4 |
| 428 |
.IX Item "$urxvt_term = $self->{term}" |
| 429 |
Returns the \f(CW\*(C`urxvt::term\*(C'\fR object associated with this instance of the |
| 430 |
extension. This member \fImust not\fR be changed in any way. |
| 431 |
.ie n .IP "$self\->enable ($hook_name => $cb\fR, [$hook_name => \f(CW$cb..])" 4 |

| 433 |
.IX Item "$self->enable ($hook_name => $cb, [$hook_name => $cb..])" |
| 434 |
Dynamically enable the given hooks (named without the \f(CW\*(C`on_\*(C'\fR prefix) for |
| 435 |
this extension, replacing any previous hook. This is useful when you want |
| 436 |
to overwrite time-critical hooks only temporarily. |

The following subroutines can be declared in extension files, and will be |
| 444 |
called whenever the relevant event happens. |
| 445 |
.PP |
| 446 |
The first argument passed to them is an extension oject as described in |
| 447 |
the in the \f(CW\*(C`Extension Objects\*(C'\fR section. |
| 448 |
.PP |
| 449 |
\&\fBAll\fR of these hooks must return a boolean value. If any of the called |
| 450 |
hooks returns true, then the event counts as being \fIconsumed\fR, and the |
| 451 |
relevant action might not be carried out by the \*(C+ code. |
| 452 |
.PP |

.ie n .IP "on_init $term" 4 |
| 455 |
.el .IP "on_init \f(CW$term\fR" 4 |
| 456 |
.IX Item "on_init $term" |
| 457 |
Called after a new terminal object has been initialized, but before |
| 458 |
windows are created or the command gets run. Most methods are unsafe to |
| 459 |
call or deliver senseless data, as terminal size and other characteristics |
| 460 |
have not yet been determined. You can safely query and change resources |
| 461 |
and options, though. For many purposes the \f(CW\*(C`on_start\*(C'\fR hook is a better |
| 462 |
place. |
| 463 |
.ie n .IP "on_start $term" 4 |
| 464 |
.el .IP "on_start \f(CW$term\fR" 4 |
| 465 |
.IX Item "on_start $term" |
| 466 |
Called at the very end of initialisation of a new terminal, just before |
| 467 |
trying to map (display) the toplevel and returning to the mainloop. |
| 468 |
.ie n .IP "on_destroy $term" 4 |
| 469 |
.el .IP "on_destroy \f(CW$term\fR" 4 |
| 470 |
.IX Item "on_destroy $term" |
| 471 |
Called whenever something tries to destroy terminal, before doing anything |
| 472 |
yet. If this hook returns true, then destruction is skipped, but this is |
| 473 |
rarely a good idea. |
| 474 |
.ie n .IP "on_reset $term" 4 |
| 475 |
.el .IP "on_reset \f(CW$term\fR" 4 |
| 476 |
.IX Item "on_reset $term" |
| 477 |
Called after the screen is \*(L"reset\*(R" for any reason, such as resizing or |
| 478 |
control sequences. Here is where you can react on changes to size-related |
| 479 |
variables. |

| 491 |
.IX Item "on_sel_make $term, $eventtime" |
| 492 |
Called whenever a selection has been made by the user, but before the |
| 493 |
selection text is copied, so changes to the beginning, end or type of the |
| 494 |
selection will be honored. |
| 495 |
.Sp |
| 496 |
Returning a true value aborts selection making by urxvt, in which case you |
| 497 |
have to make a selection yourself by calling \f(CW\*(C`$term\->selection_grab\*(C'\fR. |
| 498 |
.ie n .IP "on_sel_grab $term\fR, \f(CW$eventtime" 4 |

Called whenever a selection has been copied, but before the selection is |
| 502 |
requested from the server. The selection text can be queried and changed |
| 503 |
by calling \f(CW\*(C`$term\->selection\*(C'\fR. |

| 507 |
.el .IP "on_sel_extend \f(CW$term\fR" 4 |
| 508 |
.IX Item "on_sel_extend $term" |
| 509 |
Called whenever the user tries to extend the selection (e.g. with a double |
| 510 |
click) and is either supposed to return false (normal operation), or |
| 511 |
should extend the selection itelf and return true to suppress the built-in |
| 512 |
processing. This can happen multiple times, as long as the callback |
| 513 |
returns true, it will be called on every further click by the user and is |
| 514 |
supposed to enlarge the selection more and more, if possible. |

| 519 |
.IX Item "on_view_change $term, $offset" |
| 520 |
Called whenever the view offset changes, i..e the user or program |
| 521 |
scrolls. Offset \f(CW0\fR means display the normal terminal, positive values |
| 522 |
show this many lines of scrollback. |

.IX Item "on_scroll_back $term, $lines, $saved" |
| 526 |
Called whenever lines scroll out of the terminal area into the scrollback |
| 527 |
buffer. \f(CW$lines\fR is the number of lines scrolled out and may be larger |
| 528 |
than the scroll back buffer or the terminal. |
| 529 |
.Sp |
| 530 |
It is called before lines are scrolled out (so rows 0 .. min ($lines \- 1, |
| 531 |
\&\f(CW$nrow\fR \- 1) represent the lines to be scrolled out). \f(CW$saved\fR is the total |

Called whenever the \fB\s-1ESC\s0 ] 777 ; string \s-1ST\s0\fR command sequence (\s-1OSC\s0 = |
| 537 |
operating system command) is processed. Cursor position and other state |

information is up-to-date when this happens. For interoperability, the |

it from commands for other extensions, and this might be enforced in the |
| 541 |
future. |

Be careful not ever to trust (in a security sense) the data you receive, |

.IX Item "on_add_lines $term, $string" |
| 549 |
Called whenever text is about to be output, with the text as argument. You |
| 550 |
can filter/change and output the text yourself by returning a true value |
| 551 |
and calling \f(CW\*(C`$term\->scr_add_lines\*(C'\fR yourself. Please note that this |

| 561 |
.IX Item "on_line_update $term, $row" |
| 562 |
Called whenever a line was updated or changed. Can be used to filter |
| 563 |
screen output (e.g. underline urls or other useless stuff). Only lines |
| 564 |
that are being shown will be filtered, and, due to performance reasons, |
| 565 |
not always immediately. |

.Sp |
| 570 |
Please note that, if you change the line, then the hook might get called |

later with the already-modified line (e.g. if unrelated parts change), so |
| 572 |
you cannot just toggle rendition bits, but only set them. |
