Fixes for GHC 8.4.1 compatibility

2018-04-18T17:18:10+00:00

* 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)

a nicer pretty printing for the PGF format

added all orthographic primitives

Changes for compatibility with ghc-7.10-rc2

2015-02-16T15:05:06+00:00

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.

Prelude.CAPIT is now a built-in primitive. It still generates &| in the Haskell runtime but will be intepreted in the C runtime

full support for recursive def rules in the C runtime

2014-09-05T10:09:43+00:00

a partial support for def rules in the C runtime

2014-08-11T10:59:10+00:00

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.

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.

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

Eliminate mutual dependencies between the GF compiler and the PGF library

2013-11-05T13:11:10+00:00

+ 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%.
