digitalmars.D.announce - Goldie Parsing System v0.7 - API, 64-bit, Git

Goldie v0.7 is now released.

Goldie is a series of open-source parsing tools, including an optional D 
programming language library called GoldieLib. Goldie is compatible with 
GOLD Parser Builder and can be used either together with it, or as an 
alternative to it.

In this version:
(Tested to work on: DMD 2.052 - DMD 2.056, and partially DMD 2.057 as 
described below.)

    - Added a new Beginner's Tutorial: 
http://www.semitwist.com/goldie/Start/Tutorial/
    - Switched version control from SVN/DSource to Git/BitBucket.
    - GoldieLib: Added Token.get and Token.getRequired.
    - GoldieLib: Added traverse for parse tree traversal.
    - GoldieLib: Added op overloads as a preferred alternative to Token.subX 
for accessing subtokens in dynamic-style.
    - GoldieLib: Fixed: RangeException on Token.matches("<blah>", null) (ie, 
when attempting to match an empty rule with matches).


    - Many documentation updates/improvements including (in addition to the 
usual misc and API updates) an updated FAQ.
    - StaticLang: Creates the output path if it doesn't already exist.
    - Renamed "Parse Anything" sample to "Sample Generic Parse" (to avoid 
confusion with the Parse tool).
    - Added support for DMD 2.056. On DMD 2.057, dynamic-style works, but 

    - Now uses SemiTwist D Tools tag 'goldie-v0.7'.

 Is this capable of handling D's grammar?


Not yet, unfortunately[1] :(  LALR(1) can admittedly be somewhat limiting, I 
need to take it to something like LALR(k) or GLR (I have another idea up my 
sleeve, too...).

It is capable of tokenizing D though, and such a grammar for that is 
included (lang/dlex.grm). Although, until I add support for the GOLD v5 
features, nested comments have to be handled semi-manually - ie, go through 
the lexer's resulting token array, if you find a '/+' token then skip to the 
appropriately matching '+/' token. Should be easy, but of course it'd be 
better to not even have to bother.



don't ATM...)

[1] CS theory says that you probably could, but the resulting grammar 
wouldn't be very useful.

Oh, also, it can't properly lex the Delimited Strings yet:

Do you know of any inambigouus grammar for D?

Yes, Goldie (and GOLD) don't yet have a mechanim for disambiguation.
