    DESCRIPTION

    -

    Everytime a terminal object gets created, scripts specified via the -perl resource are loaded and associated with it.

    +

    Everytime a terminal object gets created, extension scripts specified via +the perl resource are loaded and associated with it.

    Scripts are compiled in a 'use strict' and 'use utf8' environment, and thus must be encoded as UTF-8.

    Each script will only ever be loaded once, even in rxvtd, where -scripts will be shared (But not enabled) for all terminals.

    +scripts will be shared (but not enabled) for all terminals.

    +

    +

    +

    PREPACKAGED EXTENSIONS

    +

    This section describes the extensions delivered with this release. You can +find them in /opt/rxvt/lib/urxvt/perl/.

    +

    You can activate them like this:

    +
    +  rxvt -pe <extensionname>
    +

    Or by adding them to the resource for extensions loaded by default:

    +
    +  URxvt.perl-ext-common: default,automove-background,selection-autotransform
    +
    +
    selection (enabled by default)
    +
    +
    +(More) intelligent selection. This extension tries to be more intelligent +when the user extends selections (double-click and further clicks). Right +now, it tries to select words, urls and complete shell-quoted +arguments, which is very convenient, too, if your ls supports +--quoting-style=shell. +
    +
    +

    A double-click usually selects the word under the cursor, further clicks +will enlarge the selection.

    +
    +
    +

    The selection works by trying to match a number of regexes and displaying +them in increasing order of length. You can add your own regexes by +specifying resources of the form:

    +
    +
    +
    +   URxvt.selection.pattern-0: perl-regex
    +   URxvt.selection.pattern-1: perl-regex
    +   ...
    +
    +
    +

    The index number (0, 1...) must not have any holes, and each regex must +contain at least one pair of capturing parentheses, which will be used for +the match. For example, the followign adds a regex that matches everything +between two vertical bars:

    +
    +
    +
    +   URxvt.selection.pattern-0: \\|([^|]+)\\|
    +
    +
    +

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

    +
    +
    +

    This extension also offers following bindable keyboard commands:

    +
    +
    +
    rot13
    +
    +
    +Rot-13 the selection when activated. Used via keyboard trigger: +
    +
    +
    +   URxvt.keysym.C-M-r: perl:selection:rot13
    +
    +

    +
    option-popup (enabled by default)
    +
    +
    +Binds a popup menu to Ctrl-Button2 that lets you toggle (some) options at +runtime. +
    +

    +
    selection-popup (enabled by default)
    +
    +
    +Binds a popup menu to Ctrl-Button3 that lets you convert the selection +text into various other formats/action (such as uri unescaping, perl +evaluation, web-browser starting etc.), depending on content. +
    +
    +

    Other extensions can extend this popup menu by pushing a code reference +onto @{ $term-{selection_popup_hook} }>, that is called whenever the +popup is displayed.

    +
    +
    +

    It's sole argument is the popup menu, which can be modified. The selection +is in $_, which can be used to decide wether to add something or not. +It should either return nothing or a string and a code reference. The +string will be used as button text and the code reference will be called +when the button gets activated and should transform $_.

    +
    +
    +

    The following will add an entry a to b that transforms all as in +the selection to bs, but only if the selection currently contains any +as:

    +
    +
    +
    +   push @{ $self->{term}{selection_popup_hook} }, sub {
    +      /a/ ? ("a to be" => sub { s/a/b/g }
    +          : ()
    +   };
    +
    +

    +
    searchable-scrollback<hotkey> (enabled by default)
    +
    +
    +Adds regex search functionality to the scrollback buffer, triggered +by a hotkey (default: M-s). While in search mode, normal terminal +input/output is suspended and a regex is displayed at the bottom of the +screen. +
    +
    +

    Inputting characters appends them to the regex and continues incremental +search. BackSpace removes a character from the regex, Up and Down +search upwards/downwards in the scrollback buffer, End jumps to the +bottom. Escape leaves search mode and returns to the point where search +was started, while Enter or Return stay at the current position and +additionally stores the first match in the current line into the primary +selection.

    +
    +

    +
    selection-autotransform
    +
    +
    +This selection allows you to do automatic transforms on a selection +whenever a selection is made. +
    +
    +

    It works by specifying perl snippets (most useful is a single s/// +operator) that modify $_ as resources:

    +
    +
    +
    +   URxvt.selection-autotransform.0: transform
    +   URxvt.selection-autotransform.1: transform
    +   ...
    +
    +
    +

    For example, the following will transform selections of the form +filename:number, often seen in compiler messages, into vi +$filename +$word:

    +
    +
    +
    +   URxvt.selection-autotransform.0: s/^([^:[:space:]]+):(\\d+):?$/vi +$2 \\Q$1\\E\\x0d/
    +
    +
    +

    And this example matches the same,but replaces it with vi-commands you can +paste directly into your (vi :) editor:

    +
    +
    +
    +   URxvt.selection-autotransform.0: s/^([^:[:space:]]+(\\d+):?$/:e \\Q$1\\E\\x0d:$2\\x0d/
    +
    +
    +

    Of course, this can be modified to suit your needs and your editor :)

    +
    +
    +

    To expand the example above to typical perl error messages (``XXX at +FILENAME line YYY.''), you need a slightly more elaborate solution:

    +
    +
    +
    +   URxvt.selection.pattern-0: ( at .*? line \\d+[,.])
    +   URxvt.selection-autotransform.0: s/^ at (.*?) line (\\d+)[,.]$/:e \\Q$1\E\\x0d:$2\\x0d/
    +
    +
    +

    The first line tells the selection code to treat the unchanging part of +every error message as a selection pattern, and the second line transforms +the message into vi commands to load the file.

    +
    +

    +
    readline
    +
    +
    +A support package that tries to make editing with readline easier. At the +moment, it reacts to clicking with the left mouse button by trying to +move the text cursor to this position. It does so by generating as many +cursor-left or cursor-right keypresses as required (the this only works +for programs that correctly support wide characters). +
    +
    +

    It only works when clicking into the same line (possibly extended over +multiple rows) as the text cursor and on the primary screen, to reduce the +risk of misinterpreting. The normal selection isn't disabled, so quick +successive clicks might interfere with selection creation in harmless +ways.

    +
    +

    +
    tabbed
    +
    +
    +This transforms the terminal into a tabbar with additional terminals, that +is, it implements what is commonly refered to as ``tabbed terminal''. The topmost line +displays a ``[NEW]'' button, which, when clicked, will add a new tab, followed by one +button per tab. +
    +
    +

    Clicking a button will activate that tab. Pressing Shift-Left and +Shift-Right will switch to the tab left or right of the current one, +while Shift-Down creates a new tab.

    +
    +

    +
    mark-urls
    +
    +
    +Uses per-line display filtering (on_line_update) to underline urls and +make them clickable. When middle-clicked, the program specified in the +resource urlLauncher (default x-www-browser) will be started with +the URL as first argument. +
    +

    +
    automove-background
    +
    +
    +This is basically a one-line extension that dynamically changes the background pixmap offset +to the window position, in effect creating the same effect as pseudo transparency with +a custom pixmap. No scaling is supported in this mode. Exmaple: +
    +
    +
    +   rxvt -pixmap background.xpm -pe automove-background
    +
    +

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

    +
    digital-clock
    +
    +
    +Displays a digital clock using the built-in overlay. +
    +

    +
    example-refresh-hooks
    +
    +
    +Displays a very simple digital clock in the upper right corner of the +window. Illustrates overwriting the refresh callbacks to create your own +overlays or changes. +
    +

    +
    selection-pastebin
    +
    +
    +This is a little rarely useful extension that Uploads the selection as +textfile to a remote site (or does other things). (The implementation is +not currently secure for use in a multiuser environment as it writes to +/tmp directly.). +
    +
    +

    It listens to the selection-pastebin:remote-pastebin keyboard command, +i.e.

    +
    +
    +
    +   URxvt.keysym.C-M-e: perl:selection-pastebin:remote-pastebin
    +
    +
    +

    Pressing this combination runs a command with % replaced by the name of +the textfile. This command can be set via a resource:

    +
    +
    +
    +   URxvt.selection-pastebin.cmd: rsync -apP % ruth:/var/www/www.ta-sa.org/files/txt/.
    +
    +
    +

    And the default is likely not useful to anybody but the few people around +here :)

    +
    +
    +

    The name of the textfile is the hex encoded md5 sum of the selection, so +the same content should lead to the same filename.

    +
    +
    +

    After a successful upload the selection will be replaced by the text given +in the selection-pastebin-url resource (again, the % is the placeholder +for the filename):

    +
    +
    +
    +   URxvt.selection-pastebin.url: http://www.ta-sa.org/files/txt/%
    +
    +

    +

    +

    +
    +

    API DOCUMENTATION

    General API Considerations

    All objects (such as terminals, time watchers etc.) are typical reference-to-hash objects. The hash can be used to store anything you like. All members starting with an underscore (such as _ptr or -_hook) are reserved for internal uses and must not be accessed or +_hook) are reserved for internal uses and MUST NOT be accessed or modified).

    When objects are destroyed on the C++ side, the perl object hashes are emptied, so its best to store related objects such as time watchers and the like inside the terminal object so they get destroyed as soon as the terminal is destroyed.

    +

    Argument names also often indicate the type of a parameter. Here are some +hints on what they mean:

    +
    +
    $text
    +
    +
    +Rxvt-unicodes special way of encoding text, where one ``unicode'' character +always represents one screen cell. See ROW_t for a discussion of this format. +
    +

    +
    $string
    +
    +
    +A perl text string, with an emphasis on text. It can store all unicode +characters and is to be distinguished with text encoded in a specific +encoding (often locale-specific) and binary data. +
    +

    +
    $octets
    +
    +
    +Either binary data or - more common - a text string encoded in a +locale-specific way. +
    +

    +

    +

    +

    Extension Objects

    +

    Very perl extension is a perl class. A separate perl object is created +for each terminal and each extension and passed as the first parameter to +hooks. So extensions can use their $self object without having to think +about other extensions, with the exception of methods and members that +begin with an underscore character _: these are reserved for internal +use.

    +

    Although it isn't a urxvt::term object, you can call all methods of the +urxvt::term class on this object.

    +

    It has the following methods and data members:

    +
    +
    $urxvt_term = $self->{term}
    +
    +
    +Returns the urxvt::term object associated with this instance of the +extension. This member must not be changed in any way. +
    +

    +
    $self->enable ($hook_name => $cb, [$hook_name => $cb..])
    +
    +
    +Dynamically enable the given hooks (named without the on_ prefix) for +this extension, replacing any previous hook. This is useful when you want +to overwrite time-critical hooks only temporarily. +
    +

    +
    $self->disable ($hook_name[, $hook_name..])
    +
    +
    +Dynamically disable the given hooks. +
    +

    Hooks

    -

    The following subroutines can be declared in loaded scripts, and will be called -whenever the relevant event happens.

    -

    All of them must return a boolean value. If it is true, then the event -counts as being consumed, and the invocation of other hooks is skipped, -and the relevant action might not be carried out by the C++ code.

    -

    When in doubt, return a false value (preferably ()).

    +

    The following subroutines can be declared in extension files, and will be +called whenever the relevant event happens.

    Rendition bitsets contain information about colour, font, font styles and +similar information for each screen cell.

    +

    The following ``macros'' deal with changes in rendition sets. You should +never just create a bitset, you should always modify an existing one, +as they contain important information required for correct operation of +rxvt-unicode.

    +
    +
    $rend = urxvt::DEFAULT_RSTYLE
    +
    +
    +Returns the default rendition, as used when the terminal is starting up or +being reset. Useful as a base to start when creating renditions. +
    +

    +
    $rend = urxvt::OVERLAY_RSTYLE
    +
    +
    +Return the rendition mask used for overlays by default. +
    +

    +
    $rendbit = urxvt::RS_Bold, RS_Italic, RS_Blink, RS_RVid, RS_Uline
    +
    +
    +Return the bit that enabled bold, italic, blink, reverse-video and +underline, respectively. To enable such a style, just logically OR it into +the bitset. +
    +

    +
    $foreground = urxvt::GET_BASEFG $rend
    +
    +
    $background = urxvt::GET_BASEBG $rend
    +
    +
    +Return the foreground/background colour index, respectively. +
    +

    +
    $rend = urxvt::SET_FGCOLOR $rend, $new_colour
    +
    +
    $rend = urxvt::SET_BGCOLOR $rend, $new_colour
    +
    +
    +Replace the foreground/background colour in the rendition mask with the +specified one. +
    +

    +
    $value = urxvt::GET_CUSTOM $rend
    +
    +
    +Return the ``custom'' value: Every rendition has 5 bits for use by +extensions. They can be set and changed as you like and are initially +zero. +
    +

    +
    $rend = urxvt::SET_CUSTOM $rend, $new_value
    +
    +
    +Change the custom value. +

    +

    The urxvt::anyevent Class

    +

    The sole purpose of this class is to deliver an interface to the +AnyEvent module - any module using it will work inside urxvt without +further programming. The only exception is that you cannot wait on +condition variables, but non-blocking condvar use is ok. What this means +is that you cannot use blocking APIs, but the non-blocking variant should +work.

    +

    +

    The urxvt::term Class

    +
    $term = new urxvt::term $envhashref, $rxvtname, [arg...]
    +
    +
    +Creates a new terminal, very similar as if you had started it with system +$rxvtname, arg.... $envhashref must be a reference to a %ENV-like +hash which defines the environment of the new terminal. +
    +
    +

    Croaks (and probably outputs an error message) if the new instance +couldn't be created. Returns undef if the new instance didn't +initialise perl, and the terminal object otherwise. The init and +start hooks will be called during this call.

    +
    +

    +
    $term->destroy
    +
    +
    +Destroy the terminal object (close the window, free resources +etc.). Please note that rxvt will not exit as long as any event +watchers (timers, io watchers) are still active. +
    +

    +
    $term->exec_async ($cmd[, @args])
    +
    +
    +Works like the combination of the fork/exec builtins, which executes +(``starts'') programs in the background. This function takes care of setting +the user environment before exec'ing the command (e.g. PATH) and should +be preferred over explicit calls to exec or system. +
    +
    +

    Returns the pid of the subprocess or undef on error.

    +
    +

    +
    $isset = $term->option ($optval[, $set])
    +
    +
    +Returns true if the option specified by $optval is enabled, and +optionally change it. All option values are stored by name in the hash +%urxvt::OPTION. Options not enabled in this binary are not in the hash. +
    +

    The methods currently supported on urxvt::overlay objects are:

    +
    +
    +
    $overlay->set ($x, $y, $text, $rend)
    -Switch the overlay off again. +Similar to $term->ROW_t and $term->ROW_r in that it puts +text in rxvt-unicode's special encoding and an array of rendition values +at a specific position inside the overlay.

    +
    +
    +Returns the row number of the topmost displayed line. Maximum value is +0, which displays the normal terminal contents. Lower values scroll +this many lines into the scrollback buffer. +
    +

    +
    $term->want_refresh
    +
    +
    +Requests a screen refresh. At the next opportunity, rxvt-unicode will +compare the on-screen display with its stored representation. If they +differ, it redraws the differences. +
    +
    +

    Used after changing terminal contents to display them.

    +
    +

    +
    $text = $term->ROW_t ($row_number[, $new_text[, $start_col]])
    +
    +
    +Returns the text of the entire row with number $row_number. Row 0 +is the topmost terminal line, row $term->$ncol-1 is the bottommost +terminal line. The scrollback buffer starts at line -1 and extends to +line -$term->nsaved. Nothing will be returned if a nonexistent line +is requested. +
    +
    +

    If $new_text is specified, it will replace characters in the current +line, starting at column $start_col (default 0), which is useful +to replace only parts of a line. The font index in the rendition will +automatically be updated.

    +
    +
    +

    $text is in a special encoding: tabs and wide characters that use +more than one cell when displayed are padded with $urxvt::NOCHAR +characters. Characters with combining characters and other characters that +do not fit into the normal tetx encoding will be replaced with characters +in the private use area.

    +
    +
    +

    You have to obey this encoding when changing text. The advantage is +that substr and similar functions work on screen cells and not on +characters.

    +
    +
    +

    The methods $term->special_encode and $term->special_decode +can be used to convert normal strings into this encoding and vice versa.

    +
    +

    +
    $rend = $term->ROW_r ($row_number[, $new_rend[, $start_col]])
    +
    +
    +Like $term->ROW_t, but returns an arrayref with rendition +bitsets. Rendition bitsets contain information about colour, font, font +styles and similar information. See also $term->ROW_t. +
    +
    +

    When setting rendition, the font mask will be ignored.

    +
    $length = $term->ROW_l ($row_number[, $new_length])
    +
    +
    +Returns the number of screen cells that are in use (``the line +length''). Unlike the urxvt core, this returns $term->ncol if the +line is joined with the following one. +
    +

    +
    $bool = $term->is_longer ($row_number)
    +
    +
    +Returns true if the row is part of a multiple-row logical ``line'' (i.e. +joined with the following row), which means all characters are in use +and it is continued on the next row (and possibly a continuation of the +previous row(s)). +
