GF 3.5 Release Notes
See the download page.
Over 400 changes have been pushed to the source repository since the release
of GF 3.4.
GF compiler and run-time library
- The Haskell source code for GF now compiles with GHC 7.6 and hence the
the latest Haskell Platform (2013.2.0.0).
Compatibility with GHC 7.4 is also maintained.
gf -s/-q now silences
no linearization of ... warnings.
- Faster regular expression pattern matching in the grammar compiler.
- Two bugs in the partial evaluator that caused problems with pattern macros
and variants have been fixed.
- A portability problem with PGF files has been fixed. It could cause problems
when PGF files were produced on a 32-bit system and used on a 64-bit system.
- The new runtime in C (in /src/runtime/c/)
is now stable enough to be used although there
are still features from the Haskell runtime which are not ported yet.
The new runtime provides the following new features:
- state of the art statistical parser for GF (PMCFG)
- the parser is usable in a robust mode, i.e. even if the
sentence is not in the scope of the grammar it is still possible
to get a list of parsable chunks
- the linearizer is also more robust than the one in Haskell since
it can linearize the partial trees returned from the robust parser
- the exhaustive generation for GF abstract trees generates the trees
in decreasing probability order (the order in Haskell is unspecified).
- we have started using just-in-time compilation to native code in
the exhaustive generator. The goal is to reach the state where
GF will provide state of the art theorem prover.
- There is a binding from Python to the C runtime in /src/runtime/python/.
- A volunteer to complete the binding from Java is highly wanted,
Resource Grammar Library
- New languages in the Resource Grammar Library: Greek, Maltese
(see the updated synopsis).
- Various improvements for several other languages.
- Updated web-based RGL browser (/lib/doc/browse/),
with search-by-type and inbuilt syntax tree builder.
GF Cloud services
- Word alignment diagrams can now be restricted to a subset
of the languages supported by the grammar.
- Minibar: you can now click on a linearization to obtain a table with all
variants and forms.
- Support for cross-site HTTP requests.
- A UTF-8 decoding problem in
gf -server has been fixed.
It was caused by a backward incompatible change in
- Various other small improvements and bug fixes.
