<h1 tag="repeating">Repeating commands</h1>
<toc start="2"/>

<p>
    &dactyl.appName; can repeat commands in a number of ways, from repeating
    the last command, to recording and playing macros, to saving its state and
    executing scripts.
</p>

            Repeat the last keyboard mapping <oa>count</oa> times. Note that,
            unlike in Vim, this does not apply solely to editing commands,
            mainly because &dactyl.appName; doesn't have them.

            Record a key sequence as a macro. Available macros are
            <a>0-9a-zA-Z</a>. If the macro is an uppercase letter, the
            recorded keys are appended to the lowercase macro of the same
            name. Typing <k>q</k> again stops the recording.

<h2 tag="macro-utilities">Macro utilities</h2>

<p>
    The following key bindings facilitate the recording of efficient
    macros. They have no effect when typed normally, but are
    recorded and take effect during macro playback.
</p>

<item>
    <tags><![CDATA[<sleep> <A-m>s]]></tags>

    <description>
        <p>
            Wait for the current page to finish loading before resuming
            playback. If <oa>count</oa> is given, wait no more than
            <oa>count</oa> seconds. Otherwise wait no more than 25 seconds.
        </p>
    </description>
</item>


<h2 tag="group groups">Groups</h2>

<p>
    In order to facilitate script writing, especially scripts which only
    apply to certain web sites, many types of commands and mappings can
    be assigned to a named group. In addition to helping identify the
    source of such mappings in listings, and aiding in the cleanup of
    scripts, these groups can be configured to apply only to certain web
    sites.
</p>

<item>
    <tags>:gr :group</tags>
    <spec>:gr<oa>oup</oa></spec>
    <description>
        <p>List all active <t>groups</t>.</p>
    </description>
</item>

<item>
    <spec>:gr<oa>oup</oa><oa>!</oa> <a>group</a> …</spec>
    <description>
        <p>
            Select, create, or modify a <t>group</t>. After invocation,
            <a>group</a> becomes the default group for all further commands
            issued in the current script. If <oa>!</oa> is given the group is
            cleared of all mappings, commands, and any other entries bound to
            it before making the specified additions (if any).
        </p>

        <p>The following <a>group</a> names have special meanings:</p>

        <dl>
            <dt>builtin</dt> <dd>The default group for builtin items. Can not be modified in any way by scripts.</dd>
            <dt>default</dt> <dd>The default group for this script.</dd>
            <dt>user</dt> <dd>The default group for the command line and <t>&dactyl.name;rc</t>.</dd>
        </dl>

        <p>The following arguments are available:</p>

        <dl>
            <dt>-args=<a>javascript</a></dt> <dd>JavaScript Object which
                augments the arguments passed to commands, mappings, and
                autocommands, e.g., given <str delim="">{ foo: "bar" }</str>,
                <tt>foo</tt> (<tt>&lt;foo></tt> if the Ex syntax is used) will
                be replaced by <str delim="">bar</str> inside the definitions
                (short name: <em>-a</em>)</dd>
            <dt>-description</dt> <dd>A description of this group (short names: <em>-desc</em>, <em>-d</em>)</dd>
            <dt>-locations=<a>filters</a></dt> <dd>The URLs for which this
                group should be active. See <t>site-filters</t> (short names:
                <em>-locs</em>, <em>-loc</em>, <em>-l</em>)</dd>
            <dt>-nopersist</dt> <dd>Do not save this group to an auto-generated RC file (short name: <em>-n</em>)</dd>
        </dl>
    </description>
</item>


<h2 tag="site-filter site-filters">Site Filters</h2>

<p>
    Many &dactyl.appName; commands accept filters so that they may be applied
    only to specific sites. Most of these commands accept filters in any of the
    following formats:
</p>

<dl>
    <dt>domain</dt>
    <dd>
        Any filter which is a valid domain name will match any site on that
        domain or any sub-domain thereof. These filters may contain any letter
        of the Roman alphabet, Arabic numerals, hyphens, and full stops.
        Non-Latin domain names must be punycode encoded.
    </dd>

    <dt>URL prefix</dt>
    <dd>
        Any URL beginning with a valid protocol name and ending with a
        <tt>*</tt> is treated as a URL prefix. It will match any URL which
        begins with the given filter sans the trailing asterisk.
    </dd>

    <dt>Full URL</dt>
    <dd>
        Any URL beginning with a valid protocol name and not ending with an
        asterisk is treated as a full URL match. It will match any page which
        has a URL identical to the filter.
    </dd>

    <dt>Regular expression</dt>
    <dd>
        Any filter which does not fall into one of the above categories is
        treated as a case-sensitive regular expression.
    </dd>
</dl>

<p>
    In most cases, any of the above may be prefixed with a <tt>!</tt> character
    to exclude matching sites.
</p>

<h2 tag="using-scripts">Using scripts</h2>

<item>
    <tags>:so :source</tags>
    <spec>:so<oa>urce</oa><oa>!</oa> <a>file</a></spec>
    <description>
        <p>
            Read Ex commands, JavaScript, or CSS from <a>file</a>. Files are
            interpreted based on their extensions. Files which end in
            <em>.js</em> are executed as JavaScript, while those ending in
            <em>.css</em> are loaded as Cascading Stylesheets, and anything
            else is interpreted as Ex commands. In normal cases, any errors
            generated by the execution or non-existence of <a>file</a> are
            printed to the <t>command-line</t> area.  When <oa>!</oa> is
            provided, these are suppressed.
        </p>

        <p>
            Environment variables in <a>file</a> are expanded to their current
            value, and the prefix <em>~</em> is replaced with the value of
            <em>$HOME</em>. See <t>expand-env</t> and <t>initialization</t>
            for more information.
        </p>

        <h3 tag=":source-contexts">Script Contexts</h3>

        <p>
            Each script executes in its own JavaScript context. This means that
            any global variable or function, including those defined by
            <ex>:javascript</ex> and the <tt>-javascript</tt> flag of
            <ex>:map</ex>, <ex>:command</ex>, and <ex>:autocmd</ex>,
            is directly available only within the current script. Outside of the
            current script, they can only be accessed as properties of the
            script's global object, which is stored in the <tt>plugins</tt>
            global under the script's full path.
        </p>

        <h3 tag=":source-groups">Script Groups</h3>

        <p>
            In addition to its own JavaScript context, each script is executed
            with its own default <link topic="groups">group</link> into which
            its styles, mappings, commands, and autocommands are placed. This
            means that commands such as <ex>:comclear!</ex> can be issued
            without fear of trampling other user-defined mappings. The command
            <ex>:group! default</ex> can be issued to clear all such items at
            once, and should be placed at the head of most scripts to prevent
            the accumulation of stale items when the script is re-sourced.
        </p>

        <h3 tag=":source-css">Cascading Stylesheets</h3>

        <p>
            When a CSS file is sourced, its contents are applied to every web
            page and every chrome document, including all browser windows and
            dialogs. If the same file is sourced more than once, its previous
            rules are cleared before it is applied again. Rules can be
            restricted to specific documents by enclosing them in
            <link topic="https://developer.mozilla.org/en/CSS/@-moz-document">@-moz-document</link>
            blocks.
        </p>

        <h3 tag=":source-javascript">JavaScript</h3>

        <p>
            JavaScript files are executed with full chrome privileges in their
            own global namespaces. These namespaces are stored as objects in
            the <em>plugins</em> object, in the property named after the full
            path of the sourced file. This means that any variables or
            functions created by your script are stored as properties of that
            object. Additionally, all properties of the global <em>window</em>
            and <em>modules</em> objects are accessible to your script as
            global variables.
        </p>

        <p>
            Files in <em>~/.&dactyl.name;/plugins</em> may additionally be
            accessed in <em>plugins.<a>filename</a></em> where <a>filename</a>
            is the last component of the file's path stripped of any
            extensions, with all hyphens stripped and any letter following a
            hyphen capitalized.  So, the file
            <em>~/.&dactyl.name;/plugins/foo-bar.js</em> may be accessed as
            <em>plugins.fooBar</em>. See also <t>writing-plugins</t>.
        </p>

        <h3 tag=":source-ex">Ex commands</h3>

        <p>
            Ex command files are executed as if each line were entered into
            the &tag.command-line; individually.
            Additionally, certain commands support the same ‘here document’
            syntax supported by most Unix shells and by the &tag.command-line;.
            So, to execute a JavaScript statement which does not comfortably fit
            on a single line, you can use:
        </p>

        <code><ex>:js</ex> &lt;&lt;<em>EOF</em>
<kwd><hl key="Object">var</hl></kwd> hello = <kwd>function</kwd> () {
    alert(<str>Hello world</str>);
}
<em>EOF</em></code>

    <description>
        <p>
            Immediately load all plugins which have yet to be loaded. Because
            plugins are not automatically loaded until after <tt><t>&dactyl.name;rc</t></tt>
            is sourced, this command must be placed early in the
            <tt>&dactyl.name;rc</tt> file if <tt>&dactyl.name;rc</tt> uses commands or options
            which are defined by plugins. Additionally, this command allows
            newly installed plugins to be easily loaded without restarting
            &dactyl.appName;. See also <o>loadplugins</o>.
        </p>
        <p>
            If <oa>pattern</oa>s are provided, the given regular expressions are

<h3 tag="ex-scripts">Ex Command Scripts</h3>

<p>
    Ex command scripts are similar to both entering commands on the
    &tag.command-line; and to Vim
    scripts, but with some notable differences.
</p>

<p tag="multiline-commands">
    Commands in Ex command scripts can span multiple lines by
    prefixing the second and further lines with a <em>\</em>
    character. For instance, the following all define commands whose
    definitions span multiple lines.
</p>

<code><ex>:command!</ex> <str delim="">foo</str>
        \ <em>-description</em> <str>A command that frobs bars</str>
        \ <ex>:javascript</ex> frob(content.bar)</code>

<code><ex>:style</ex> <em>-name</em> <str delim="'">foo</str>
     \ <str delim="'">foobar.com</str>
     \ p<str delim="">:first-line</str> { <em>font-variant</em>: <str delim="">small-caps</str>; }
     \ div<em>#side-bar</em> > <str delim="">:first-child</str> { <em>display</em>: <str delim="">none</str>; }</code>

<code><ex>:command!</ex> <str delim="">do-some-stuff</str>
        \ <em>-description</em> <str>A command which does some stuff in JavaScript</str>
        \ <ex>:javascript</ex> &lt;&lt;<em>EOF</em>
        \     window.do(<str>some</str>);
        \     window.do(<str>stuff</str>);
        \<em>EOF</em></code>

<code><ex>:command!</ex> <str delim="">do-some-stuff</str>
        \ <em>-description</em> <str>A command which does some stuff in JavaScript</str>
        \ <ex>:javascript</ex>
        \\    window.do(<str>some</str>);
        \\    window.do(<str>stuff</str>);</code>

<p tag="comments">
    Lines may be commented out by prefixing them with a <em>"</em>
    character.
</p>

<code>            <hl style="color: #444">" This is a comment</hl>
    foo bar <hl style="color: #444">" This is a comment</hl>
            <str> This is not a comment</str>
    foo bar <str> This is not a comment</str>
