Completing directories with special suffix

Completing directories with special suffix

[Will Sargent]

Hello all,

I'm trying to get the zsh code completion to expand out java directories and
application modules so that I have directory completion set up with the dot
instead of the slash.

As an example, I'd like to be able to do with java and a directory
/com/foo/bar containing a file Main.class

   java -classpath . com.foo.bar.Main

using the dot prefix to expand on com.f<tab>, if that makes any sense.

I also use ATG Dynamo heavily, so which uses application modules in the same
style.  I have a script for this, but it still expands things out with the /
tag.  It's almost what I want, but not quite; I'd also like it so that only
directories which contain a META-INF directory are considered.

So given a directory structure

    $DYNAMO_ROOT/
		DAS/
			META-INF/
			LDAP/
				META-INF/
				iPlanetDirectory/
					META-INF/
		DPS/
			META-INF/
		home/
			no meta inf dir here/

Then

  startDynamo -m DAS.LDAP.iPlanetDirectory

would be expanded out, but home wouldn't be on the possible list, and DPS
wouldn't have any child completions.

I've created a file called _modules with the following text

#autoload

# Because of the way that the files options are processed, need to pass in
# DYNAMO_ROOT and not $DYNAMO_HOME/..

# We also want to find files which contain a META-INF directory.
# We also want to be able to expand out sub-modules.

DYNAMO_ROOT=$DYNAMO_HOME/..

_files -/ -W DYNAMO_ROOT

but that's as far as I've gotten for now.

What should I change to get the code working like I want?

And of course, two seconds I send that I find that there's already a java
completion.  Duh.

I'll look at that and see if I can scavange some code.

I solved this in a non-zsh fashion by writing a program called classfind that
parsed my classpath and built a cache of classes vs. package/directory.

So I can identify which jar I pick up a particular class from.

I then built a zsh completion around it, such that this program was invoked for
 'java com.oopsconsultancy.<TAB>'. So it doesn't complete on directories, but
from your classpath.

More details if you're interested.

That sounds like a great idea; parse out the classpath and then do
completion on it.  Woo.

I don't parse out the classpath. Rather I perform the completion function, and
generate the possible package names (and cache them for later use). So I can
complete on a classpath setting (including .zips and .jars) rather than on a
directory basis. Which is what you really want.

Don't know yet if the zsh 4.x completions handle this. Unfortunately my current
client is stuck on 3.x at the moment :-( Hopefully I can check this out next
week.

Yeah, that was what I meant.

Do you do completion in place, so you can define a classpath and expand out
the package in the same line?  Something along the lines of

java -cp jedit.jar org.gjt.jedit.JEdit

would be supercool.

Will.
