2018-04-18Fixes for GHC 8.4.1 compatibilityThomas Hallgren
* In GHC 8.4.1, the operator <> has become a method of the Semigroup class and is exported from the Prelude. This is unfortunate, since <> is also exported from the standard library module Text.PrettyPrint, so in any module that defines a pretty printer, there is likely to be an ambiguity. This affects ~18 modules in GF. Solution: import Prelude hiding (<>) This works also in older versions of GHC, since GHC does't complain if you hide something that doesn't exists. * In GHC 8.4.1, Semigroup has become a superclass of Monoid. This means that anywhere you define an instance of the Monoid class you also have to define an instance in the Semigroup class. This affects Data.Binary.Builder in GF. Solution: conditionally define a Semigroup instance if compiling with base>=4.11 (ghc>=8.4.1)

2015-02-16Changes for compatibility with ghc-7.10-rc2hallgren
2 modules: Name clashes caused by Applicative-Monad change in Prelude 2 modules: Ambiguities caused by Foldable/Traversable in Prelude 2 modules: Backwards incompatible changes in time-1.5 for defaultTimeLocale 9 modules: {-# LANGUAGE FlexibleContexts #-} (because GHC checks inferred types now, in addition to explicitly given type signatures) Also silenced warnings about tab characters in source files.
2014-10-09Prelude.CAPIT is now a built-in primitive. It still generates &| in the ↵kr.angelov
Haskell runtime but will be intepreted in the C runtime
2014-09-05full support for recursive def rules in the C runtimekr.angelov
2014-08-11a partial support for def rules in the C runtimekr.angelov
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.
2013-11-12added Predef.SOFT_BIND. This special token allows zero or more spaces ↵kr.angelov
between ordinary tokens. It is also used in the English RGL to attach the commas to the previous word.
2013-11-06the content of ParseEngAbs3.probs is now merged with ParseEngAbs.probs. The ↵kr.angelov
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
2013-11-05Eliminate mutual dependencies between the GF compiler and the PGF libraryhallgren
+ References to modules under src/compiler have been eliminated from the PGF library (under src/runtime/haskell). Only two functions had to be moved (from GF.Data.Utilities to PGF.Utilities) to make this possible, other apparent dependencies turned out to be vacuous. + In gf.cabal, the GF executable no longer directly depends on the PGF library source directory, but only on the exposed library modules. This means that there is less duplication in gf.cabal and that the 30 modules in the PGF library will no longer be compiled twice while building GF. To make this possible, additional PGF library modules have been exposed, even though they should probably be considered for internal use only. They could be collected in a PGF.Internal module, or marked as "unstable", to make this explicit. + Also, by using the -fwarn-unused-imports flag, ~220 redundant imports were found and removed, reducing the total number of imports by ~15%.
2013-10-30added the linref construction in GF. The PGF version number is now bumpedkr.angelov
2013-09-27a major refactoring in the C and the Haskell runtimes. Note incompatible ↵kr.angelov
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.

syntax
2011-11-10Now PMCFG is compiled per module and at the end we only link it. The new ↵kr.angelov
compilation schema is few times faster.

2010-03-24now for every category we store, in PGF, the list of functions for it in ↵krasimir
