heading::Automatic{nbsp}commands[autocommands]

Autocommands are a way to automatically execute code when certain events
happen.

|:au| |:autocmd| +
||:au[tocmd]||
________________________________________________________________________________
Execute commands automatically on events.

[c]:au[tocmd][c] {event} {pat} {cmd}

If the *-javascript* (short name *-js*) option is specified, {cmd} is executed
as JavaScript code, with any supplied arguments available as variables.

Add {cmd} to the list of commands Vimperator will execute on {event} for a URL matching {pat}:

* [c]:autocmd[!][c] {events} {pat}: list/remove autocommands filtered by {events} and {pat}
* [c]:autocmd[!][c] {events}: list/remove autocommands matching {events}
* [c]:autocmd[!][c] * {pat}: list/remove autocommands matching {pat}
* [c]:autocmd[!][c]: list/remove all autocommands

Available {events}:

{pat} is a regular expression, use .* if you want to match all URLs.

Note: This differs from Vim which uses a glob rather than a regex for {pat}.

The following keywords are available where relevant:

[frame="topbot",grid="none",cols="1,4"]
|===============================================================================
|*<url>*    |The URL against which the event was selected.
|*<title>*  |The page, bookmark or download title.
|*<doc>*    |The document for which the event occurred. Only for *DOMLoad*, *PageLoad* and *PageLoadPre*.
|*<tab>*    |The tab in which the event occurred. Only for *DOMLoad*, *PageLoad* and *PageLoadPre*.
|*<tags>*   |The tags applied to <url>. Only for *BookmarkAdd*.
|*<keyword>*|The keywords applied to the bookmark. Only for *BookmarkAdd*.
|*<icon>*   |The icon associated with <url>. Only for *BookmarkAdd*.
