Subject: Re: ruby language parser in ruby

A minor problem with the redparse gem is that it gives most of the files 
root-only permissions. I just did 'sudo gem install redparse'

$ pwd
/usr/lib/ruby/gems/1.8/gems/redparse-0.8.3
$ ls -l lib
total 96
drwxr-xr-x 2 root root  4096 2009-12-04 14:07 redparse
-rwx------ 1 root root 89730 2009-12-04 14:07 redparse.rb
$ ls -l lib/redparse
total 188
-rwx------ 1 root root   2542 2009-12-04 14:07 babynodes.rb
-rwx------ 1 root root   6348 2009-12-04 14:07 babyparser.rb
-rwx------ 1 root root  10545 2009-12-04 14:07 decisiontree.rb
-rw-r--r-- 1 root root  13385 2009-12-04 14:07 generate.rb
-rwxr-xr-x 1 root root 134917 2009-12-04 14:07 node.rb
-rwxr--r-- 1 root root   2041 2009-12-04 14:07 problemfiles.rb
-rwx------ 1 root root   2664 2009-12-04 14:07 reg_more_sugar.rb
-rwxr--r-- 1 root root     40 2009-12-04 14:07 version.rb

Easily fixable of course:

sudo bash
find . -type f | xargs chmod +r
find . -type d | xargs chmod +rx

Most of those .rb files don't need +x either, since they don't have a 
shebang line.

Looking at this code - I don't think I would dare hack it. I think 
ruby_parser is more what I was looking for.
