This just gave me a 404 Page Not Found.

Ah, sorry, that's supposed to be an SVN URL.

I am glad to announce the first release of rubyfront (a ruby parser powered
by antlr).

Even though this is the first release, rubyfront can parse entire
ruby standard library (over 1500 .rb files).

To download or check out more
details about rubyfront, please go to http://seclib.blogspot.com/2006/02/first-release-of-rubyfront.html


Rubyfront uses BSD license. I am going to write more about it on my blog
later.

This is GREAT news (and I don't say that often).

I installed J2SE 5.0 right after reading this.

Here are the results of the smoke tests with a 1.8 tree from 2006-01-14:

parsersmoketest:

        def initialize( type, val )
            @type_id = type; @value = val
            @value.taguri = "x-private:#{ @type_id }"
        end
        def to_yaml( opts = {} )
            @value.to_yaml( opts )
        end
    ensure

    end

Thank for the feedbacks! They look like easy problems and I will fix them
soon.

In a few months when ANTLR v3 is a little further along, I'll do the  
conversion and see how it looks :)

Out of curiousity, are you working with Martin Traverso at all, or
independently?

I think it'd be great if we could get you two together to avoid
duplicated work.

Ah, never mind.  I see this is a v2 grammar; he's doing a native v3
grammar.  Still, it might be cool to have you guys compare notes.

Hi Mauricio,
  I fixed all the bugs you reported, here is smoke test result
I ran against current ruby stable snapshot:

parsersmoketest:

 [java]
1575 ruby programs have been parsed, 0 failed.

And now rubyfront can accept
Ruby on Rails's source code as well. You are going to see a few failures,
but they are expected (.rhtml files are not valid ruby script).

Please
download from:
http://www.seclib.com/rubyfront/download/rubyfront.zip

Thank you!
