<p>
<span class="application">medit</span> has some editing options which can be set in the document text,
or in the <span class="guilabel">Preferences</span> dialog for sets of files or for given syntax
highlighting language.
</p>
<p>
To set the options in the document text, place the following on the first,
second or the last line of the document:
</p>
<pre class="programlisting">
-%- <em class="parameter"><code>options</code></em> -%-
</pre>
<p>
where <em class="parameter"><code>options</code></em> is the option string
</p>
<pre class="programlisting">
<em class="parameter"><code>key</code></em>: <em class="parameter"><code>value</code></em>; <em class="parameter"><code>key</code></em>: <em class="parameter"><code>value</code></em>; ...
</pre>
<p>
(the latter is the format used also in the <span class="guilabel">Preferences</span> dialog).
</p>
<p>
For example, the following might be the first line in a C file:
</p>
<pre class="programlisting">
/* -%- indent-width: 2; use-tabs: yes; strip: yes -%- */
</pre>
<p>
</p>
<p>
Values can be strings, integers, or booleans.
</p>
<p>
Booleans are <code class="code">yes</code>, <code class="code">no</code>, <code class="code">true</code>, <code class="code">false</code>, <code class="code">1</code>, <code class="code">0</code>.
</p>
<p>
If a string value contains <code class="code">:</code> character, then the following syntax may be used:
<code class="code"><em class="parameter"><code>key</code></em>=/<em class="parameter"><code>value</code></em>/</code>. Any character may be used instead of slash (and it
must not occur in the <em class="parameter"><code>value</code></em>). Example: <code class="code">word-chars=@-/:@</code>
</p>
<p>
The following options are available:
</p>
<div class="variablelist"><table border="0">
<col align="left" valign="top">
<tbody>
<tr>
<td><p><span class="term"><code class="code">lang</code></span> : </p></td>
<td><p>syntax highlighting language to use in this document. Special value <code class="code">none</code> will
turn off syntax highlighting in this document.</p></td>
</tr>
<tr>
<td><p><span class="term"><code class="code">strip</code></span> : </p></td>
<td><p>a boolean value, whether trailing whitespace should be removed from the document on save.</p></td>
</tr>
<tr>
<td><p><span class="term"><code class="code">add-newline</code></span> : </p></td>
<td><p>a boolean value, whether the editor should ensure that saved files have a trailing new line character.</p></td>
</tr>
<tr>
<td><p><span class="term"><code class="code">indent-width</code></span> : </p></td>
<td><p>an integer specifying indentation offset used when the Tab key is pressed to indent text.</p></td>
</tr>
<tr>
<td><p><span class="term"><code class="code">tab-width</code></span> : </p></td>
<td><p>displayed width of the tab character. Note that this is <span class="emphasis"><em>not</em></span> the same as
<code class="code">indent-width</code>.</p></td>
</tr>
<tr>
<td><p><span class="term"><code class="code">use-tabs</code></span> : </p></td>
<td><p>whether tab character should be used for indentation.</p></td>
</tr>
</tbody>

</p>
<p>
<span class="application">medit</span> tries to understand modelines of Vim, Emacs, and Kate text editors, so chances are it will correctly
pick up the conventional settings from source files.
