584d589041 a partial support for def rules in the C runtime
The def rules are now compiled to byte code by the compiler and then to
native code by the JIT compiler in the runtime. Not all constructions
are implemented yet. The partial implementation is now in the repository
but it is not activated by default since this requires changes in the
PGF format. I will enable it only after it is complete.

d9f4c1598c a quick hack to enable the NERC from bindings. This should be made available from the API but for now I just hacked the C runtime 2014-04-10 07:27:07 +00:00

0095119ec0 added Predef.SOFT_BIND. This special token allows zero or more spaces between ordinary tokens. It is also used in the English RGL to attach the commas to the previous word. 2013-11-12 09:54:57 +00:00

af4a1f628d factor of 3 speedup for the translation without slowing down the grammar loading. The parser still seems to be 8 times slower than before I introduced the BIND. At least the Android UI now feels a lot more comfortable 2013-11-07 11:14:32 +00:00

2483dc7728 the content of ParseEngAbs3.probs is now merged with ParseEngAbs.probs. The later is now retrained. Once the grammar is compiled with the .probs file now it doesn't need anything more to do robust parsing. The robustness itself is controlled by the flags 'heuristic_search_factor', 'meta_prob' and 'meta_token_prob' in ParseEngAbs.gf 2013-11-06 10:21:46 +00:00

8cf03bc5b6 a major redesign in the C runtime. The parser and the linearizer now fully support BIND. The following things are still broken: parseval, word completion, handling 'pre', the robust mode 2013-10-09 12:08:51 +00:00

e8335806af GuString is now an ordinary C string - it makes live easier. In addition PgfSymbolKS, PgfExprFun and PgfLiteralStr now keep their strings as embedded flexible arrays. The latest change gives us the same compactness as the old representation but it is a lot easier to use. 2013-10-04 12:04:39 +00:00

426bc49a52 a major refactoring in the C and the Haskell runtimes. Note incompatible change in the PGF format!!!
The following are the outcomes:

   - Predef.nonExist is fully supported by both the Haskell and the C runtimes

   - Predef.BIND is now an internal compiler defined token. For now
     it behaves just as usual for the Haskell runtime, i.e. it generates &+.
     However, the special treatment will let us to handle it properly in 
     the C runtime.

   - This required a major change in the PGF format since both 
     nonExist and BIND may appear inside 'pre' and this was not supported
     before.
