APaGeD - Attributed Parser Generator for D

http://apaged.mainia.de

This is a major upgrade for ALLPaGeD. It has been renamed to APaGeD,
because it's not restricted to LL parsers anymore.

- generates LALR(1)-based GLR parsers and LL parsers
- generates linear-time first-longest-match lexical analyzers
- intuitive, curly-brace-style grammar syntax with embedded D code
- supports non-regular whitespace grammar (e.g. nested comments)
- semantic analysis allows inherited and synthetic attributes, multiple
passes, etc.
- supports imports for structuring of large grammars
- extensive debugging facilities
- supports error recovery
- explicit error messages or...
- automatically generated error messages: "file(line): found A, expected
B, C or D"
- export grammar specification for documentation

See the documentation for details.

WOW !!!!!!!!!!!!
Written in D 1x ?
Well asking for the SEAT D grammar is probabely a bit too much. But however, will you offer us the grammar file ?

I think it is included in the seatd downloadable. Check src/seatd/parser.apd.

it's written in D2.0, but the generated parsers also compile with D1.0.

the SEATD grammar file is available with the source!?
it's in src/seatd/parser.apd

Seems, that APaGeD gegenrates GLR-parsers by default, but I cannot see that in the documentation.

Minor bug: When the parser is to accept epsilon only, then there are no lexems defined, then no mainLexer will be generated, then the compilation will fail.

i'll fix both in the next release, thanks.

Nice work, thanks!
minor bug: when calling apaged without any arguments, it segfaults.
changing line 29 in main.d to this fixes this:

optionsLoop: while ( args.length > 1 )
