For those interested in things Ruby and grammatical, grammarian Xue Yong Zhi presents: ----- Forwarded message from removed\_email\_address@domain.invalid ----- Date: 17 Feb 2006 05:22:01 -0000 From: removed\_email\_address@domain.invalid Reply-To: removed\_email\_address@domain.invalid Subject: [grammarians] First release of Rubyfront To: removed\_email\_address@domain.invalid 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](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.

Not necessarily, it should be useful for all sorts of toolchains - it’s just not possible to invoke it from a Ruby app. It might also be interesting to port this to pure Ruby once the ANTLR Ruby backend matures. (Correct me if already did since I last checked.) Having a proper Ruby parser in Ruby might make writing tools like RDoc much easier. David V. ---

(Correct me if already did since I last checked.) I think it’s pretty mature now actually, though I haven’t played with it. The Ruby backend is part of ANTLR v3, though. yawl’s grammar is for v2. Martin (the author of the v3 Ruby backend) has a partial v3 Ruby grammar in TRGP SVN now; I don’t know whether we’ll ultimately polish that up, or port yawl’s grammar to v3. At the moment, Ter’s leaning towards the latter, as it’s more complete. But we’ll see how it goes. > Having a proper Ruby parser in Ruby might make writing tools like RDoc > much easier. That’s the plan. Not to mention Ruby implementations like JRuby. I’ve actually got some evil ideas for a Ruby-in-Javascript implementation (Ruby in the browser, yay!), but I’m not touching that one until we have a decent parser waiting in the wings. -mental ---

I was not aware taht ANTLR could generate a pure Ruby parser. …of course there is Ripper (not sure what the current status is) and other similar projects like ParseTree, nodeTree, etc. Phil ---

Even if we had other flawless pure ruby parsers, having an ANTLR grammar around for all manners of “Ruby in not-Ruby” weirdness seems to definately to have perks by itself. I wonder if mental is petting a white persia cat plotting his evil plan… David V.
