[FR-devel] Source parser changes

[Richard Kilmer]

All,

I have been quite worried for some time regarding the source parser 
(ripper) that we were using.  Specifically, it was built off of a 2 
year old Ruby parser, and it has problems running under 1.8 on some 
platforms.  Since there is no Ruby parser that we can use, I wrote a 
basic parser that creates the source parser tree by simply using the 
indent levels of lines...and matches on

class <name>

module <name>

def <name>

It uses regex's and is quite fast.  As an optimization, I do a SHA1 
hash of the parsed data and if it has not changed it returns the prior 
parse tree.  To test it load a couple of the big ruby files (like 
databus.rb, etc) and open the source parser and flip back and forth 
between files.  I added files to the rubyide_tools_fox_source_browser 
and rubyide_tools_source_parser plugins and change the plugin.yaml 
files to point to these...so it is possible to go back to the old 
ripper-based parser by simply changing these files.

If a couple of folks could use this and let me know how it works for 
you it would be great.
