It has a similar interface as <code class="code code1 language-latex lang-latex latex colorized">pgfkeys</code> with
path options but comes with more built-in data types and more convenient
support for families and searching.
</p>
<p class="p indent">The main features of <code class="code code1 language-latex lang-latex latex colorized">options</code> are:
</p>
<ul class="ul list-star loose">
<li class="li ul-li list-star-li loose-li">
<p><em class="em-low1">Declare your options only once</em>: in most packages you usually need to
declare both a new command, and the option that sets it. In the
<code class="code code1 language-latex lang-latex latex colorized">options</code> package you declare the option just once. For example,
<code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\options</span>{/my/len/.new length}</code> and then use it anywhere else as
<code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\option</span>{/my/len}</code>.
</p></li>
<li class="li ul-li list-star-li loose-li">
<p><em class="em-low1">Use paths for keys</em>: just like <code class="code code1 language-latex lang-latex latex colorized">pgfkeys</code>, the <code class="code code1 language-latex lang-latex latex colorized">options</code> package uses
paths (instead of families) to declare options and prevent name clashes
between different packages. Paths are convenient for complex options,
like <code class="code code1 language-latex lang-latex latex colorized">border/left/width</code>, and are also convenient to specify searches.
</p></li>
<li class="li ul-li list-star-li loose-li">
<p><em class="em-low1">Many built-in data types</em>: the <code class="code code1 language-latex lang-latex latex colorized">options</code> library comes with many
useful data types like <code class="code code1 language-latex lang-latex latex colorized">choice</code>, <code class="code code1 language-latex lang-latex latex colorized">list</code>, <code class="code code1 language-latex lang-latex latex colorized">toggle</code>, <code class="code code1 language-latex lang-latex latex colorized">num</code>, <code class="code code1 language-latex lang-latex latex colorized">dim</code>,
<code class="code code1 language-latex lang-latex latex colorized">length</code>, <code class="code code1 language-latex lang-latex latex colorized">glue</code>, commands, and plain values, and it is easy to add
your own (Section <a href="#sec-datatypes" title="3.1. Basic data types" class="localref" style="target-element:h2"><span class="heading-label">3.1</span></a>. Also you can hook into existing
definitions like an <code class="code code1 language-latex lang-latex latex colorized">if</code> or <code class="code code1 language-latex lang-latex latex colorized">counter</code> (Section <a href="#sec-hooks" title="3.3. Using existing definitions" class="localref" style="target-element:h2"><span class="heading-label">3.3</span></a>).
</p></li>
<li class="li ul-li list-star-li loose-li">
<p><em class="em-low1">Value options</em>: You can define value-only options that start with a
special character, like <code class="code code1 language-latex lang-latex latex colorized">"Georgia"</code> for a font option, or
<code class="code code1 language-latex lang-latex latex colorized">!8080FF</code> for a color option (Section <a href="#sec-special" title="6.3. Single option values" class="localref" style="target-element:h2"><span class="heading-label">6.3</span></a>).
</p></li>
<li class="li ul-li list-star-li loose-li">
<p><em class="em-low1">Convenient searches</em>: you can specify paths that should be searched
from other paths and redirect even from absolute paths. For complex
packages this is very useful to inherit common options
(Section <a href="#sec-searches" title="2.2. Paths and searches" class="localref" style="target-element:h2"><span class="heading-label">2.2</span></a>).
</p></li>
<li class="li ul-li list-star-li loose-li">
<p><em class="em-low1">Easy filtering</em>: it is easy to collect unknown options and process
them later. Combined with the search mechanism this makes it easy to
do custom processing (Section <a href="#sec-searches" title="2.2. Paths and searches" class="localref" style="target-element:h2"><span class="heading-label">2.2</span></a>).
</p></li>
<li class="li ul-li list-star-li loose-li">
<p><em class="em-low1">It is fast</em>: for simple user options, the <code class="code code1 language-latex lang-latex latex colorized">options</code> package is a bit
faster than <code class="code code1 language-latex lang-latex latex colorized">pgfkeys</code> and if searches or filters are involved it is
usually about twice as fast as <code class="code code1 language-latex lang-latex latex colorized">pgfkeys</code> (and about six times faster
as <code class="code code1 language-latex lang-latex latex colorized">xkeyval</code>) (Section <a href="#sec-perf" title="8. Performance" class="localref" style="target-element:h1"><span class="heading-label">8</span></a>).
</p></li>
<li class="li ul-li list-star-li loose-li">
<p><em class="em-low1">Handles class and package options</em>: use the same option declarations
to handle the options passed to a class or package
(Section <a href="#sec-process-options" title="5.1. Processing options" class="localref" style="target-element:h2"><span class="heading-label">5.1</span></a>).

<h2 id="sec-overview" class="h1 sans-serif" data-heading-depth="1" style="display:block;font-weight:normal"><span class="heading-before"><span class="heading-label">2</span>. </span>Overview</h2>
<p class="p noindent">Defining options is very easy. As an example, we will make an <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\mybox</span></code> command
that takes named options. Our goal is that the user can invoke <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\mybox</span></code> like:
</p>
<pre class="para-block pre-indented language-latex lang-latex latex colorized" style="display:block"><code><span style="color:navy">\mybox</span>{padding=<span class="constant" style="color:navy">1ex</span>, border/width=<span class="constant" style="color:navy">0.4pt</span>, font/style=italic}{text}</code></pre><h3 id="sec-an-example" class="h2 sans-serif" data-heading-depth="2" style="display:block;font-weight:normal"><span class="heading-before"><span class="heading-label">2.1</span>. </span>An example</h3>
<p class="p noindent">We can define the options for our <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\mybox</span></code> command as:
</p>
<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>
<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block;line-adjust:0;text-indent:0pt"><code><span style="color:navy">\options</span>{
/mybox/.new family,
/mybox/padding/.new length = <span style="color:navy">\fboxsep</span>,
/mybox/border/width/.new length = <span style="color:navy">\fboxrule</span> * 2,
/mybox/border/color/.new color,
/mybox/font/style/.new choice = {normal,italic,small-caps},
}</code></pre>
<p class="p noindent">The options are all specified as a <em class="em-low1">path</em> where names that start with a
dot, like <code class="code code1 language-latex lang-latex latex colorized">.new length</code> are called <em class="em-low1">handlers</em>. In this case, the handlers
create the options for our box command. To parse the options passed by
the user, we use the same <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\options</span></code> command:
</p>
<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>
<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block;line-adjust:0;text-indent:0pt"><code><span style="color:navy">\newcommand</span><span style="color:navy">\mybox</span>[2]{<span style="color:darkgreen">%</span>
{<span style="color:navy">\options</span>{/mybox,<span class="constant" style="color:navy">#1</span>}<span style="color:darkgreen">%</span>
<span style="color:navy">\myboxdisplay</span>{<span class="constant" style="color:navy">#2</span>}<span style="color:darkgreen">%</span>
}<span style="color:darkgreen">%</span>
}</code></pre>
<p class="p noindent">Here we start the option list with <code class="code code1 language-latex lang-latex latex colorized">/mybox</code> which makes that the default
path (because it was declared with <code class="code code1 language-latex lang-latex latex colorized">.new family</code>) so the user can give
relative option names instead of prefixing all options with <code class="code code1 language-latex lang-latex latex colorized">/mybox/</code>.
Options are always set local to the current group.
</p>
<p class="p indent">Finally, we can use <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\option</span>{<span class="code-escaped"><span class="param serif" style="font-size:120%">〈<em class="em-star1">option</em>〉</span></span>}</code> to get the value of an option.
This command expands directly to the command name (i.e. <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\optk@</span><span class="code-escaped"><span class="param serif" style="font-size:120%">〈<em class="em-star1">option</em>〉</span></span></code>)
and is very efficient. So, our implementation for displaying our box may
look like:
</p>
<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>
<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block;line-adjust:0;text-indent:0pt"><code><span style="color:navy">\newcommand</span><span style="color:navy">\myboxdisplay</span>[1]{<span style="color:darkgreen">%</span>

<span style="color:navy">\setlength</span><span style="color:navy">\fboxrule</span>{<span style="color:navy">\option</span>{/mybox/border/width}}<span style="color:darkgreen">%</span>

<span style="color:navy">\fi</span>
<span class="constant" style="color:navy">#1</span><span style="color:darkgreen">%</span>
}<span style="color:darkgreen">%</span>
}</code></pre>
<p class="p noindent">Here, instead of using the <code class="code code1 language-latex lang-latex latex colorized">font/style</code> directly, we use the automatically
generated <code class="code code1 language-latex lang-latex latex colorized">font/style/<span style="color:navy">@ord</span></code> that gives the ordinal of the choice on which we
can match more efficiently. Here is our new command in action:

<p class="p noindent">Another improvement is in our choice definition for the font. Instead of using
a case over the choice ordinal, we can set the required font command directly
as the value of the choice options, we show this in Section <a href="#sec-datatypes" title="3.1. Basic data types" class="localref" style="target-element:h2"><span class="heading-label">3.1</span></a>.

<p class="p noindent">The option paths are mainly used to prevent name clashes between different
packages but they can also be used for searches. In particular, we can
specify for any path that if a sub-path cannot be found, we should look
under another path. Suppose we define a new <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\fancymybox</span></code> command that
takes some extra options. In that case, we would like to re-use the
<code class="code code1 language-latex lang-latex latex colorized">/mybox</code> options and look for any undefined options under <code class="code code1 language-latex lang-latex latex colorized">/mybox</code> instead:
</p>
<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>
<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block;line-adjust:0;text-indent:0pt"><code><span style="color:navy">\options</span>{
/fancymybox/.new family = {/mybox}, <span style="color:darkgreen">% search also /mybox</span>
/fancymybox/border/radius/.new length,
/fancymybox/rounded/.new style = [<span class="constant" style="color:navy">5pt</span>]{/fancymybox/border/radius = <span class="constant" style="color:navy">#1</span>},
}</code></pre>
<p class="p noindent">Note how the <code class="code code1 language-latex lang-latex latex colorized">rounded</code> style takes an argument which is defaulted to <code class="code code1 language-latex lang-latex latex colorized"><span class="constant" style="color:navy">5pt</span></code>.
In the <code class="code code1 language-latex lang-latex latex colorized">.new family</code> declaration, we can provide a list of search paths: here we just
gave <code class="code code1 language-latex lang-latex latex colorized">/mybox</code> such that any options not found under <code class="code code1 language-latex lang-latex latex colorized">/fancymybox</code> will be looked up
under <code class="code code1 language-latex lang-latex latex colorized">/mybox</code>:

<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>
<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block;line-adjust:0;text-indent:0pt"><code><span style="color:navy">\options</span>{/fancymybox, rounded=<span class="constant" style="color:navy">10pt</span>, border/normal} </code></pre>
<p class="p noindent">In the previous sample, <code class="code code1 language-latex lang-latex latex colorized">/mybox/border/normal</code> is invoked. In general, we
can add comma separated search paths either in a <code class="code code1 language-latex lang-latex latex colorized">.new family</code> declaration
or using the <code class="code code1 language-latex lang-latex latex colorized">.search also</code> handler. Search paths can be added to any path
and will apply recursively. For example, if we set:
</p>
<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>
<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block;line-adjust:0;text-indent:0pt"><code><span style="color:navy">\options</span>{

/b/bar/y/.new cmd* = y,
/c/a/.search also = {/a/foo},
/c/b/.search also = {/b},
/c/.new family = {/a,/b},
}</code></pre>
<p class="p noindent">Then all of the following options are resolved:

<p class="p noindent">Note that the <code class="code code1 language-latex lang-latex latex colorized">options</code> package will even search if an absolute path
is given, and always searches with the relative sub-path.
</p>
<p class="p indent">This is important for modularity since it allows us for example to combine
options of different sub packages. For example, if I want to handle options
under <code class="code code1 language-latex lang-latex latex colorized">/package A</code> and <code class="code code1 language-latex lang-latex latex colorized">/package B</code> together, I can just define a new
family:
</p>
<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block"><code><span style="color:navy">\options</span>{ /packageAB/.new family = {/package A,/package B}}</code></pre>
<p class="p noindent para-continued">and start processing options using <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\options</span>{/packageAB,..}</code>. Even
when the user now uses absolute paths like <code class="code code1 language-latex lang-latex latex colorized">/packageAB/<span class="code-escaped"><span class="param serif" style="font-size:120%">〈<em class="em-star1">name</em>〉</span></span></code> the
option search will route it automatically to the sub packages.
</p>
<p class="p indent">Also note that for efficiency, the basic <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\option</span></code> command does <em class="em-low1">not</em>
search and always expands directly to the command name. Therefore, in
implementation code we still need to use <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\option</span>{/a/foo/x}</code> and cannot
use <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\option</span>{/c/foo/x}</code> for example.

<p class="p noindent">The command takes a list of options that are processed before the options
in the remaining list. It is allowed to pass in <code class="code code1 language-latex lang-latex latex colorized">/options/collectunknown</code>
right away again to collect any new remaining options.
</p>
<p class="p indent">The <code class="code code1 language-latex lang-latex latex colorized">/options/remaining</code> is list is only cleared when using the <code class="code code1 language-latex lang-latex latex colorized">/options/collectunknown</code>
style. This can be useful to collect unknown options using multiple passes
of <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\optionsalso</span></code>.
</p>
<p class="p indent">Besides using the remaining list, you can also define general <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">@unknown</span></code>
handlers on any path. When an option not found, the library looks
bottom-up for <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">@unknown</span></code> handlers and invokes it with the path and its
argument if found. The general handler <code class="code code1 language-latex lang-latex latex colorized">/<span style="color:navy">@unknown</span></code> will raise a package
error.
</p>
<p class="p indent">You can customize this behavior by installing an <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">@unknown</span></code> handler

arguments. The initial value is always <code class="code code1 language-latex lang-latex latex colorized"><span class="code-escaped"><span class="param serif" style="font-size:120%">〈<em class="em-star1">choice<sub>1</sub></em>〉</span></span></code>. We always need to enclose the
choice list with braces to distinguish the comma used to separate the choices from the
comma used to separate the options. For convenience, the <code class="code code1 language-latex lang-latex latex colorized">new choice</code> handler also
defines <code class="code code1 language-latex lang-latex latex colorized"><span class="code-escaped"><span class="param serif" style="font-size:120%">〈<em class="em-star1">option</em>〉</span></span>/<span style="color:navy">@ord</span></code> that contain the ordinal of the current choice (starting

The ordinal is a number and can be tested efficiently using
<code class="code code1 language-latex lang-latex latex colorized">ifcase</code> and <code class="code code1 language-latex lang-latex latex colorized">ifnum</code>. For example:

<p class="p noindent">Another powerful feature is to define the values that each choice
implies. By default this is the name of the choice but we can assign
anything else. For example, for our <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\mybox</span></code> command, we could have
specified the font style as:
</p>
<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>

<p class="p noindent">The value of <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\option</span>{/test/font/style}</code> is not the choice name now, but
the command that we assigned to it. We can now use the option directly
instead of doing a case on the <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">@ord</span></code> value:

<p class="p noindent">This section gives an overview of more advanced mechanisms,
like defining handlers and new data types.
</p><h3 id="sec-handlers" class="h2 sans-serif" data-heading-depth="2" style="display:block;font-weight:normal"><span class="heading-before"><span class="heading-label">6.1</span>. </span>Handlers</h3>
<p class="p noindent">Names that start with a dot are <em class="em-low1">handlers</em>. These are commands that are
called with the current option path and argument, and are used for example to declare
new options (e.g. <code class="code code1 language-latex lang-latex latex colorized">.new choice</code>), to change the environment (e.g. <code class="code code1 language-latex lang-latex latex colorized">.cd</code>), or to
transform the argument (e.g. <code class="code code1 language-latex lang-latex latex colorized">.expanded</code>).
</p>
<p class="p indent">You can define your own handler <code class="code code1 language-latex lang-latex latex colorized">.<span class="code-escaped"><span class="param serif" style="font-size:120%">〈<em class="em-star1">name</em>〉</span></span></code> by adding a command option under
<code class="code code1 language-latex lang-latex latex colorized">/handlers/<span class="code-escaped"><span class="param serif" style="font-size:120%">〈<em class="em-star1">name</em>〉</span></span></code>. For example, let's make a handler that transforms a
color argument from a HTML format <code class="code code1 language-latex lang-latex latex colorized">#XXXXXX</code> to a named color:
</p>
<div class="mathdefs input-mathdefs" style="line-adjust:0"></div>
<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block;line-adjust:0;text-indent:0pt"><code><span style="color:navy">\options</span>{<span style="color:darkgreen">%</span>
/handlers/htmlcolor/.new transformer = {<span style="color:darkgreen">%</span>
<span style="color:darkgreen">% we need to change the \optionvalue </span>
<span style="color:darkgreen">% #1 = current path, #2 = current \optionvalue</span>
<span style="color:navy">\definecolor</span>{<span class="constant" style="color:navy">#1</span>/<span style="color:navy">@color</span>}{HTML}{<span class="constant" style="color:navy">#2</span>}<span style="color:darkgreen">%</span>

<p class="p noindent">There are various kinds of handlers:
</p>
<ul class="ul list-star compact">
<li class="li ul-li list-star-li compact-li"><code class="code code1 language-latex lang-latex latex colorized">.new handler</code>: a general handler that does not chain nor invoke the original option.
</li>
<li class="li ul-li list-star-li compact-li"><code class="code code1 language-latex lang-latex latex colorized">.new operation</code>: chains with other handlers but does not invoke the original option.
</li>
<li class="li ul-li list-star-li compact-li"><code class="code code1 language-latex lang-latex latex colorized">.new transformer</code>: transforms the <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\optionvalue</span></code> and chains with other handlers.

<p class="p noindent">Handlers are also used to define the standard data types and can be used
to define new data types yourself. Here is for example how the <code class="code code1 language-latex lang-latex latex colorized">value</code>
data type is defined:
</p>
<pre class="para-block pre-fenced pre-fenced3 language-latex lang-latex latex colorized" style="display:block"><code><span style="color:navy">\option</span>{
/handlers/new value/.new handler = []<span style="color:navy">\optionsalso</span>{<span style="color:darkgreen">%</span>
<span class="constant" style="color:navy">#1</span>/.new cmd = <span style="color:navy">\option@set</span>{<span class="constant" style="color:navy">#1</span>}{<span class="constant" style="color:navy">##1</span>},
<span class="constant" style="color:navy">#1</span>/.type = value,
<span class="constant" style="color:navy">#1</span>/.initial = {<span class="constant" style="color:navy">#2</span>},
},
}</code></pre>
<p class="p noindent para-continued">The <code class="code code1 language-latex lang-latex latex colorized">.new handler</code> receives the current path (<code class="code code1 language-latex lang-latex latex colorized"><span class="constant" style="color:navy">#1</span></code>) and the initial value (<code class="code code1 language-latex lang-latex latex colorized"><span class="constant" style="color:navy">#2</span></code>).
The default value provided at definition time is empty (<code class="code code1 language-latex lang-latex latex colorized">[]</code>). When a user
defines a new value, we simply set more options based on the path. When the
defined option is set, the <code class="code code1 language-latex lang-latex latex colorized">.new cmd</code> is called with the argument (<code class="code code1 language-latex lang-latex latex colorized"><span class="constant" style="color:navy">##1</span></code>) and
we use that set the actual option value directly: <code class="code code1 language-latex lang-latex latex colorized"><span style="color:navy">\option@set</span>{<span class="constant" style="color:navy">#1</span>}{<span class="constant" style="color:navy">##1</span>}</code>.
Usually, we do some additional processing here, for example, for choice values
we would check if the choice is valid.
</p><h3 id="sec-special" class="h2 sans-serif" data-heading-depth="2" style="display:block;font-weight:normal"><span class="heading-before"><span class="heading-label">6.3</span>. </span>Single option values</h3>
<p class="p noindent">Finally, we can also specify handlers that are invoked when the option name
starts with special character. This allows you to handle, say, a quoted value
like <code class="code code1 language-latex lang-latex latex colorized">"Georgia"</code> as a shorthand for <code class="code code1 language-latex lang-latex latex colorized">/font/family=Georgia</code>. As an example, we
will handle options that start with a bang (<code class="code code1 language-latex lang-latex latex colorized">!</code>) as an HTML color.
Handling a special character <code class="code code1 language-latex lang-latex latex colorized"><span class="code-escaped"><span class="param serif" style="font-size:120%">〈<em class="em-star1">char</em>〉</span></span></code> can be done simply by installing a handler

<p class="p noindent">So both <code class="code code1 language-latex lang-latex latex colorized">options</code> and <code class="code code1 language-latex lang-latex latex colorized">pgfkeys</code> are quite a bit faster than <code class="code code1 language-latex lang-latex latex colorized">xkeyval</code>,
and <code class="code code1 language-latex lang-latex latex colorized">options</code> performs quite well when searches are involved. We also
tested against the basic <code class="code code1 language-latex lang-latex latex colorized">keyval</code> package but this is a bit tricky since
<code class="code code1 language-latex lang-latex latex colorized">keyval</code> does not support features like searching in the first place.
It was about 1.5 times faster on simple queries though.
