Drupal Highlighting for GeSHi

Good Idea,

Would you want me to put it in CVS already?
For example in a directory 'misc' or something?

I've written this small Python script to extract function names and "define" constants:

#!/usr/bin/env python

import os
import re
import sys

# get drupal path from command line
try:
  drupal_path = sys.argv[1]
except IndexError:
  print "usage: %s drupal_path" % sys.argv[0]
  sys.exit()

# get source code files from includes and modules directories
source_code_files = []
for subdir in ['includes', 'modules']:
  for data in os.walk(os.path.join(drupal_path, subdir)):
    for filename in data[2]:
      if os.path.splitext(filename)[1] in ['.php', '.module', '.inc']:
        source_code_files.append(os.path.join(data[0], filename))

# regular expression pattern for getting function names
function_name_rep = re.compile(r'^function\s+([a-zA-Z0-9_]+)\s*\(')
# regular expression pattern for getting constant_names
constant_rep = re.compile(r'^(define|DEFINE)\(["\']([A-Z0-9_]+)')

function_names = []
constant_names = []
for filename in source_code_files:
  for line in file(filename):
    match = function_name_rep.match(line)
    if match:
      function_names.append(match.group(1))
    match = constant_rep.match(line)
    if match:
      constant_names.append(match.group(2))

print "function names:"
print function_names

print "constant names:"
print constant_names

Maybe it's better to create a directory 'geshi_extra' where users can put their custom language definitions (and where drupal.php would be by default). Just like one should put contrib drupal modules in "/sites/all/modules" instead of "/modules" to keep the drupal core directories clean.
I think it is possible to make GeSHi also scan extra directories for language definitions. But I'll have to look into this.

Subscribing. Awesome work guys :)

fixed in
http://drupal.org/cvs?commit=91131 : GeSHi filter module now also looks for language definition files in geshi-extra directory, added drupal5 and drupal6 definition files

After updating to 5.x-2.3 the language cache needed to be flushed but now GeSHi is better than ever. Thanks guys.

After updating to 5.x-2.3 the language cache needed to be flushed

Did you run update.php?
I added a hook_update_N() function for flushing that cache automatically on the update to 5.x-2.3.

Thanks

Oops, it looks like I missed that. Thanks for the reminder.
