Installing Edit Modes</h2></div></div></div><p>The easiest way to install a new mode locally is to use the Editing
dialog found under Utilities - Global Options. At the bottom of this dialog
is an "Add Mode" button. Clicking this button shows a dialog to add a mode
to jEdit. Simply fill in the blanks and the mode file will be put in the
proper place and the catalog file will be updated appropriately. Modes added
this way can be removed by selecting the mode in the Editing dialog, then
clicking the "Delete Mode" button. This button will only appear for modes
that exist in the user settings directory. Core modes, that is, those modes
distributed with jEdit cannot be deleted this way. The details of adding a
mode by hand are below.
</p><p>jEdit looks for edit modes in two locations; the
<code class="filename">modes</code> subdirectory of the jEdit settings directory, and
the <code class="filename">modes</code> subdirectory of the jEdit install directory.
The location of the settings directory is system-specific; see <a class="xref" href="settings-directory.html" title="The jEdit Settings Directory">the section called “The jEdit Settings Directory”</a>.</p><p>Each mode directory contains a <code class="filename">catalog</code> file. All
edit modes contained in that directory must be listed in the catalog,
otherwise they will not be available to jEdit.</p><p>Catalogs, like modes themselves, are written in XML. They consist of a
single <code class="literal">MODES</code> tag, with a number of
<code class="literal">MODE</code> tags inside. Each mode tag associates a mode name
with an XML file, and specifies the file name and first line pattern for the
mode. A sample mode catalog looks as follows:</p><pre class="programlisting"><?xml version="1.0"?>
<!DOCTYPE CATALOG SYSTEM "catalog.dtd">
<MODES>
<MODE NAME="shellscript" FILE="shellscript.xml"
FILE_NAME_GLOB="*.sh"
FIRST_LINE_GLOB="#!/*sh*" />
</MODES></pre><p>In the above example, a mode named <span class="quote">“<span class="quote">shellscript</span>”</span> is
defined, and is used for files whose names end with
<code class="filename">.sh</code>, or whose first line starts with <span class="quote">“<span class="quote">#!/</span>”</span>
and contains <span class="quote">“<span class="quote">sh</span>”</span>.</p><p>The <code class="literal">MODE</code> tag supports the following
attributes:</p><div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; "><li class="listitem"><p><code class="literal">NAME</code> - the name of the edit mode, as it
will appear in the <span class="guimenuitem"><strong>Buffer Options</strong></span> dialog
box, the status bar, and so on.</p></li><li class="listitem"><p><code class="literal">FILE</code> - the name of the XML file containing
the mode definition.</p></li><li class="listitem"><p><code class="literal">FILE_NAME_GLOB</code> - files whose names match
this glob pattern will be opened in this edit mode.
This can also specify full paths, if the glob pattern contains a
path separator character. <code class="literal">FILE_NAME_GLOB</code> can be
specified in the <code class="literal">modes/catalog</code> file, or the mode
file itself. See the <code class="literal">FILE_NAME_GLOB</code> for
<code class="literal">apacheconf.xml</code> in <code class="literal">modes/catalog</code>
for an example of full path filename globbing.
</p></li><li class="listitem"><p><code class="literal">FIRST_LINE_GLOB</code> - files whose first line
matches this glob pattern will be opened in this edit mode.</p></li></ul></div><p>Glob pattern syntax is described in <a class="xref" href="globs.html" title="Appendix D. Glob Patterns">Appendix D, <i>Glob Patterns</i></a>.</p><div class="tip" style="margin-left: 0.5in; margin-right: 0.5in;"><h3 class="title">Tip</h3><p>If an edit mode in the user-specific catalog has the same name as
an edit mode in the system catalog, the version in the user-specific
catalog will override the system default.</p></div><p> When a buffer is opened, jEdit must choose an edit mode for that buffer.
It checks conditions in this order to decide which edit mode to use: </p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem"><p> the filename is an exact match for the <code class="literal">FILE_NAME_GLOB</code>. </p></li><li class="listitem"><p> the filename matches the <code class="literal">FILE_NAME_GLOB</code> and the first line of the file matches the <code class="literal">FIRST_LINE_GLOB</code></p></li><li class="listitem"><p> the filename matches the <code class="literal">FILE_NAME_GLOB</code> </p></li><li class="listitem"><p> the first line of the file matches the <code class="literal">FIRST_LINE_GLOB</code></p></li></ol></div></div><div class="navfooter"><hr><table width="100%" summary="Navigation footer"><tr><td width="40%" align="left"><a accesskey="p" href="mode-match-type.html">Prev</a> </td><td width="20%" align="center"><a accesskey="u" href="writing-modes-part.html">Up</a></td><td width="40%" align="right"> <a accesskey="n" href="updating-modes.html">Next</a></td></tr><tr><td width="40%" align="left" valign="top">The MATCH_TYPE Attribute </td><td width="20%" align="center"><a accesskey="h" href="index.html">Home</a></td><td width="40%" align="right" valign="top"> Chapter 12.
