<h1 tag="options">Options</h1>
<toc start="2"/>

<p>
    &dactyl.appName; has a number of internal variables and switches which can be set to
    achieve special effects. These options come in the following forms:
</p>

<dl dt="width: 10em;">
    <dt/><dd tag="boolean"/>
    <dt>boolean</dt>
    <dd>
        Can only be <hl key="Boolean">on</hl> (<ex>:set <a>option</a></ex>) or
        <hl key="Boolean">off</hl> (<ex>:set no<a>option</a></ex>)
    </dd>

    <dt>number</dt>        <dd>A numeric value</dd>
    <dt>string</dt>        <dd>A string value</dd>

    <dt/><dd tag="charlist"/>
    <dt>charlist</dt>
    <dd>A string containing a discrete set of distinct characters</dd>

    <dt/><dd tag="stringlist"/>
    <dt>stringlist</dt>
    <dd>
        A comma-separated list of strings. Any comma appearing within single
        or double quotes, or prefixed with a <tt>\</tt>, will not be treated
        as an item separator.
    </dd>

    <dt/><dd tag="stringmap"/>
    <dt>stringmap</dt>
    <dd>A comma-separated list of key-value pairs, e.g., <str delim="">key:val,foo:bar</str></dd>

    <dt/><dd tag="regexplist"/>
    <dt>regexplist</dt>
    <dd>
        A comma-separated list of regular expressions. Expressions may be
        prefixed with a <tt>!</tt>, in which case the match will be negated. A
        literal <tt>!</tt> at the beginning of the expression may be matched
        with <tt>[!]</tt> or by placing the regular expression in quotes.
        Generally, the first matching regular expression is used. Any comma
        appearing within single or double quotes, or prefixed with a
        <tt>\</tt>, will not be treated as an item separator.
    </dd>

    <dt/><dd tag="regexpmap"/>
    <dt>regexpmap</dt>
    <dd>
        A combination of a <t>stringmap</t> and a <t>regexplist</t>. Each key
        in the <a>key</a>:<a>value</a> pair is a regexp. If the regexp begins with a
        <tt>!</tt>, the sense of the match is negated, such that a non-matching
        expression will be considered a match and <html:i>vice versa</html:i>.
        The first <a>key</a> to match yields value.
    </dd>

    <dt>sitelist</dt> <dd tag="sitelist sitemap"/>
    <dt>sitemap</dt>
    <dd>
        Like <t>regexplist</t> and <t>regexpmap</t>, but the keys are
        <t>site-filters</t> rather than regular expressions.
    </dd>
</dl>

<p tag="macro-string">
    Some options may be given format strings containing macro replacements in
    the form of <tt>&lt;<a>name</a>></tt>. These tokens are replaced by
    the parameter <a>name</a> as specified in the relevant documentation.
    If the token is in the form <tt>&lt;q-<a>name</a>></tt>, the value of the
    parameter is automatically <link topic="quoting">quoted</link>. If it is in
    the form of <tt>&lt;e-<a>name</a>></tt>, its value is never shown but may be
    used to test whether the given parameter is empty.
</p>
<p>
    Array elements, such as in the <tt>&lt;args></tt> parameter
    of <ex>:command</ex> macros, may be accessed by appending
    <tt>[<a>n</a>]</tt>, where <a>n</a> is the one-based array
    index, to the macro name. The first argument of a command is
    therefore accessed with <tt>&lt;args[1]&gt;</tt>.
</p>
<p>
    Any substring enclosed by <em><tt>&lt;{</tt></em> and <em><tt>}></tt></em>
    is automatically elided if any of the contained macros aren't currently
    valid. A literal <em><tt>&lt;</tt></em> or <em><tt>></tt></em> character may
    be included with the special escape sequences <tt>&lt;lt></tt> or
    <tt>&lt;gt></tt> respectively.
</p>

<p style="text-align: left">
    For example, given the format string
    <str>&lt;{(cmd: &lt;column>) }>&lt;{line: &lt;line> }>&lt;file></str>,
    where <em>line</em>=<hl key="Number">32</hl> and
    <em>file</em>=<str delim="'">Lieder eines fahrenden Gesellen.txt</str>,
    the result is formatted as
    <str>line: 32 'Lieder eines fahrenden Gesellen.txt'</str>

    <description>
        <p>For list options, toggle the specified values.</p>

        <p style="text-align: left;">
            If the option is a list, the given values are toggled. Given,
            <se opt="opt" link="false"><str delim="">foo</str>,<str delim="">bar</str></se>
            then,
            <se opt="opt" op="!=" link="false"><str delim="">foo</str>,<str delim="">baz</str></se>
            has the same result as
            <se opt="opt" link="false"><str delim="">bar</str>,<str delim="">baz</str></se>
        </p>

        <p>
            This extends to string options in a natural way, e.g.,
            <se opt="stal" op="!="><str delim="">always</str>,<str delim="">never</str></se>
            toggles between the two values.

            Subtract the <a>value</a> from a number option, or remove the
            <a>value</a> from a string option if it is there. If the
            <a>value</a> is not found in a string option, there is no error or
            warning. When the option is a comma separated list, a comma is
            deleted, unless the option becomes empty. When the option is a list
            of flags, <a>value</a> must be exactly as they appear in the option.
            Remove flags one by one to avoid problems.

        <p>
            Enables automatic completion for completion contexts (see
            <ex>:contexts</ex>) matching the given regular expressions. When
            automatic completion is enabled, the completion list is
            automatically opened when the &tag.command-line; is focused.
            Thereafter, any key press triggers a completion update for the
            matching contexts. Non-matching contexts will only be updated when
            the <k name="Tab" mode="c"/> key is pressed. This option is useful
            for disabling auto-completion for computationally intensive
            contexts that don't perform well when your system is under load.
        </p>

        <note>
            Completion contexts have names very much like Unix path names.
            These denote the tree in which they're called. A completer will
            never be called unless every completer preceding it in the tree
            was also called. For example, if your completer excludes
            <str>/ex/</str>, it will also exclude <str>/ex/bmarks</str>, and
            so on.
        </note>

        <example>
            To enable auto-completion for everything but <ex>:history</ex> or
            <ex>:bmarks</ex>, you would choose a value such as
            <str delim="">!/ex/(bmarks|history),.?</str>
        </example>

        <p>
            To go in the other direction, i.e. <em>only</em> enable
            auto-completion for those commands, you have to jump through
            some hoops, due to the way contexts work (see the note above):
            <str delim="">/ex/(bmarks|history),^(/|/ex/?)$</str>

            Additionally, native search providers can be added by prefixing
            their names with the string <str delim="'">native:</str>. These
            providers are often added by other add-ons and are occasionally
            useful.

        <p>
            The order is important, such that <se opt="complete">

            followed by matching quick searches and then matching files.

        <note>
            For backward compatibility, this option currently accepts a single
            entry containing single-letter names for completers. This usage
            is deprecated and will be removed in the future.
        </note>

        <warning>
            Using <em>bookmark</em> and <em>history</em> can make completion very slow if
            there are many items.

            Input fields default to this behavior irrespective of this option's
            setting.

        <p>
            Text Edit mode can be entered with <k name="C-t" mode="I"/> from Insert mode.

        <p>
            A regular expression list that defines which plugins are loaded at
            startup or via <ex>:loadplugins</ex>. The first item to match is
            the one that takes effect. If no items match, the file is not
            loaded. Setting this to a blank value effectively disables plugin
            loading.
        </p>
        <p>
            For example, to prepend to the default value of this option to load
            all plugins except for <em>foobar-plugin</em>, you could use:
        </p>
        <set opt="loadplugins" op="^=">!<str delim="'">foobar-plugin</str></set>
        <p>
            Alternatively, you can specify which plugins to load and which to
            omit in your <tt><t>&dactyl.name;rc</t></tt> using something like
            the following:
        </p>
        <set opt="loadplugins">!<str delim="'">foo|bar</str>,<str delim="'">\.(js|&dactyl.fileExt;)$</str></set>
        <p>
            That will load all plugins but <em>foo</em> and <em>bar</em>.
        </p>
        <p>
            Note that in the first expression of the latter example you don't
            need parentheses, as the <em>!</em> negates the whole of the
            following expression (cf. <t>regexplist</t>).

            Pass certain keys through directly for the given URLs.
            For any page with a URL matching a given <t>site-filter</t>, all key
            events for keys listed in the corresponding value are passed
            through directly to &dactyl.host;, and are not processed
            by &dactyl.appName; in any way. Key names are separated
            by commas, where the first key name is treated as a list
            of individual keys and each subsequent key is treated as
            a key chain. Individual key entries always apply to all
            modes. Key chains apply only to non-input modes unless
            they begin with a key requiring a modifier other than
            shift.
        </p>

        <example><set opt="passkeys" op="+="><str delim="">mail.google.com</str>:<str delim="">jk&lt;CR></str>,<str delim="">gi</str></set></example>

        <p>
            More subtle and complex pass through can be achieved
            using <t>groups</t> and mode-specific mappings utilizing
            the <k name="Pass"/> pseudo-key.

            middle-, shift-, or control- clicking a link is unaffected by this
            option.
        </p>

        <p>Possible values are:</p>

        <dl dt="width: 8em;">

        <p>
            If neither <em>tab</em> nor <em>window</em> is provided, all

            Define which info messages are displayed. As the value increases,
            &dactyl.appName; will show more messages about its progress.
            These can be viewed at any time with the <ex>:messages</ex>
            command. The highest useful value is 15, being the most verbose
            mode.

            Regular expression list defining which completion groups show only
            matches anchored to the beginning of the result. The first
            matching expression is the one that applies. If the match is
            negated, then the current filter may match anywhere in the result.
            If it is not negated, then the match may only occur at the
            beginning of the result. If no items match, then a
            context-dependent default value is used.

            List of path name patterns to ignore when completing files and
            directories. For example, the following will ignore object files
            and Vim swap files:

            Defines how command-line completion works. It is a comma-separated
            list of parts, where each part specifies what to do for each
            consecutive press of the <k name="Tab" mode="c"/> key. The last
            element in the list is used for each succeeding <k name="Tab" mode="c"/>
            after it has been reached.
        </p>

        <p>These are the possible values for each part:</p>

        <dl>
            <dt><str></str></dt>             <dd>Complete only the first match.</dd>
            <dt><str>full</str></dt>         <dd>Complete the next full match. After the last, the original string is used.</dd>
            <dt><str>longest</str></dt>      <dd>Complete the longest common substring of all completions.</dd>
            <dt><str>list</str></dt>         <dd>When more than one match, list all matches.</dd>
            <dt><str>list:full</str></dt>    <dd>When more than one match, list all matches and complete the first match.</dd>
            <dt><str>list:longest</str></dt>
            <dd>
                When more than one match, list all matches and
                complete till the longest common string. When there
                is only a single match, it is fully completed
                regardless of the case.
