Isolationism

I decided to spend my Friday working on a small side-project for work; as mentioned in a few earlier posts, I wanted to learn a bit of CherryPy and Cheetah, so it looks like this is my chance.

Since jEdit is my favourite text editor, and I couldn’t find an existing mode definition out there for Cheetah’s template (*.tmpl) format, I made one myself. Not exactly rocket science, but it might save someone a few minutes.

To install it:

• Copy the XML source below to a new file, cheetah.xml, in your $home/.jedit/modes/ directory.
• Edit the catalog file in the same directory. Add an entry somewhere that looks something like this:<MODE NAME="Cheetah Template" FILE="cheetah.xml" FILE_NAME_GLOB="*.tmpl" />
• Restart jEdit then load a Cheetah template file. Hopefully everything looks pretty.

<?xml version="1.0"?>

<!DOCTYPE MODE SYSTEM "xmode.dtd">

<MODE>
	<PROPS>
		<PROPERTY NAME="commentStart" VALUE="<!--" />
		<PROPERTY NAME="commentEnd" VALUE="-->" />
		<PROPERTY NAME="lineComment" VALUE="##" />
	</PROPS>
	<RULES>
		<!-- Everything else is an XML tag -->
		<IMPORT DELEGATE="html::MAIN"/>

		<!-- Embedded python functions -->
		<EOL_SPAN DELEGATE="python::MAIN">#</EOL_SPAN>

		<!-- In-line Variable definitions -->
		<IMPORT DELEGATE="CHEETAH_VAR" />
	</RULES>
	<RULES SET="CHEETAH_VAR">
		<!-- These were stolen from php.xml -->
		<!-- (Class-)Variables -->
		<SEQ_REGEXP TYPE="KEYWORD3" HASH_CHAR="$" DELEGATE="OBJECT_PHP">$w+(?=([[sw'"]+])?->)</SEQ_REGEXP>
		<MARK_PREVIOUS TYPE="KEYWORD3">::</MARK_PREVIOUS>

		<SEQ_REGEXP HASH_CHAR="$" TYPE="KEYWORD3">$w+(?=s*=s*(&s*)?new)</SEQ_REGEXP>

		<!-- Normal variables -->
		<MARK_FOLLOWING TYPE="KEYWORD3">$</MARK_FOLLOWING>
	</RULES>
</MODE>
