My tasks
I occasionally create tasks, usually with some reference implementation in a reasonably-common language like C, Perl, or JavaScript.

As of 2011-08-05, the highlighting works essentially correctly. Remaining issues:
- Types don't work. gp2c types (e.g.,
:mp
) are highlighted as though they were commands, and GP types (e.g.,"t_INT"
) are not highlighted at all. - Escapes in strings are not highlighted, though they are properly detected in terms of ending strings.
- Defaults that conflict with keywords (
simplify
andlog
) are highlighted wrong; not a big deal. - Default keywords and types are highlighted outside their proper context, though this is probably not a big deal.
- Colors should probably be changed (my fault!); member functions and strings are too conspicuous and defaults and error types are not conspicuous enough. Maybe a desaturated green for strings and switch the blue-violet used for defaults and errors with the purple of the member functions.
- New functions, defaults, constants, etc. from 2.6 need to be added
