Also add ghc-7.8.3 to the list of tested compiler versions

The translation is currently good enough to translate all concrete syntaxes
of the Foods and Letter grammars, and some concrete syntaxes of the Phrasebook
grammar (e.g. PhrasebookEng & PhrasebookSpa works, but there are problems with
e.g. PhrasebookSwe and PhrasebookChi)
This functionality is enabled by running
gf -make -output-format=haskell -haskell=concrete ...
TODO:
- variants
- pre { ... }
- eta expansion of linearization functions
- record subtyping can still cause type errors in the Haskell code
in some cases
- reduce code large tables

This replaces the hardwired ANSI escape codes that were accidentally included
in a previous patch.
This adds a dependency on terminfo, but this should be unproblematic, since
haskeline already depends on the same underlying C library.
The color highlighting is omitted on Windows.

It appears that GHC can't keep GF.hs and gf.hs apart on systems with case
insensitive file names.
|
|
The module src/compiler/GF.hs now serves as a prelimiary compiler API. It just
exports a selection of functions and types from the compiler.
Haddock documentation can be generated with
cabal haddock --hyperlink-source
Also bumbed the version number to 3.6.10.

* httpd-shed-0.4 does not specify an upper bound on network, but it fails
to build against network>=2.6. This is fixed in httpd-shed-0.4.0.2.
* With network-2.6, the Network.URI modules is moved to a separate package,
so for the time being GF requires network>=2.3 && <2.6. This is compatible
with the four most recent versions of the Haskell Platform.

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.

src/runtime/haskell/PGF/Internal.hs:17:8:
Could not find module ‘Data.Binary.IEEE754’
It is a member of the hidden package ‘data-binary-ieee754-0.4.4’.
Perhaps you need to add ‘data-binary-ieee754’ to the build-depends in your .cabal file.

Also bumped version number in gf.cabal to 3.6-darcs.
Also removed some unecessary use of CPP.

PGF exports the public, stable API.
PGF.Internal exports additional things needed in the GF compiler & shell,
including the nonstardard version of Data.Binary.

1. Like pgf-translate, it now shows one result at a time, press Enter to get
more results.
2. You can load a new grammar with the command 'i <path-to-pgf>'

This makes it explicit that we no longer support compiling GF with GHC 6.12
(which is 4 years old and comes with base-4.2).
|
|
+ Programs compiled with ghc<7.8 have a default built-in 8M stack size limit.
With ghc>7.0 this built-in default can be changed, so it is now 64M, allowing
GF to work with larger grammars without manually increasing the stack size.
(But if GF is compiled with ghc 6.12, the built-in default is still 8M.)
+ Enable ghc>=7.8 support for compiling modules in parallel, to speed up the
compilation of GF.

They are thus part of the PGF Run-Time Library, making it possible to add
lexing functionality in PGF service in a natural way.

Two of the fixes were in the custom version of the binary package. We
should get rid of it at some point, to reduce the maintenance burden.
The third fix was to add new version constraints for happy and alex in
gf.cabal. New versions of them are needed because of the ugly, low-level,
GHC-specific code they produce need to be different for GHC 7.8.
More fixes might be needed for -server mode, but the cgi package is not
compatible with GHC 7.8 at the moment, so it will have to wait.
|
|
Also add PGF service command c-flush to explicitly flush cached parse results
from memory.
|
|
|
|
This is to make it easier to find the cause of space leaks.

If the C run-time library is compiled and installed on your system, you can now
do 'cabal configure -fc-runtime' to get the following extras:
+ The haskell binding to the C run-time library will be included in the
PGF library (so you can import it in Haskell applications).
Documentation on the new modules will be included when you run
'cabal haddock'.
+ The new command 'pgf-shell', implemented on top of haskell binding to
the C run-time system.
+ Three new commands in the web API: c-parse, c-linearize and
c-translate. Their interfaces are similar to the corresponding commands
without the "c-" prefix, but they should be considered preliminary.

Some backwards incompatible changes were made to the PGF file format after
the release of GF 3.5. This patch adds a module for reading PGF files in the
old format.
This means that old PGF files on the grammaticalframework.org server will
continue to work after we install the latest version of GF.

file for the abstract and one more for each concrete syntax. This is a preparation for being able to load only specific languages from the whole grammar.

* The old way: a user hook in Setup.hs
* The new way: specify it in gf.cabal
* The test suite is now called gf-tests, and it runs testsuite/run.hs.
* You can run it manually with 'runhaskell testsuite/run.hs'. It also runs,
together with rgl-tests, when you do 'cabal test'
* Currently only 9 of 34 tests pass. Many failures have silly causes:
- Error messages that look slightly different
- Same output but in a different order
- Absolute paths in output

This means that the -old-comp and -new-comp flags are not recognized anymore.
The only functional difference is that printnames were still normalized with
the old partial evaluator. Now that is done with the new partial evaluator.

1. The default encoding is changed from Latin-1 to UTF-8.
2. Alternate encodings should be specified as "--# -coding=enc", the old
"flags coding=enc" declarations have no effect but are still checked for
consistency.
3. A transitional warning is generated for files that contain non-ASCII
characters without specifying a character encoding:
"Warning: default encoding has changed from Latin-1 to UTF-8"
4. Conversion to Unicode is now done *before* lexing. This makes it possible
to allow arbitrary Unicode characters in identifiers. But identifiers are
still stored as ByteStrings, so they are limited to Latin-1 characters
for now.
5. Lexer.hs is no longer part of the repository. We now generate the lexer
from Lexer.x with alex>=3. Some workarounds for bugs in alex-3.0 were
needed. These bugs might already be fixed in newer versions of alex, but
we should be compatible with what is shipped in the Haskell Platform.

write for instance 'ab.c' and then everything between the quites is identifier. This includes Unicode characters and non-ASCII symbols. This is useful for automatically generated GF grammars.

The test suite tests the French Bescherelle paradigms.

The only use of PGF.Tree outside the PGF library was in GF.Command.Commands,
and it was eliminated by using PGF.Expr directly instead.
PGF.Paraphrase still uses PGF.Tree.
|
|
This module should not be part of the public PGF library API, and it was only
used in GF.CompileToAPI, so the code was moved there. The module defined
constFuncs and syntaxFuncs, but only syntaxFuncs was used.
|
|
+ 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%.

for the PGF library since otherwise building GF applications will fail

|
The standard binary package has improved efficiency and error handling [1], so
in the long run we should consider switching to it. At the moment, using it is
possible but not recommended, since it results in incomatible PGF files.
The modified modules from the binary package have been moved from
src/runtime/haskell to src/binary.

The refresh pass does not correctly keep track of the scope of local variables
and can convert things like \x->(\x->x) x into \x1->(\x2->x2) x2. Fortunately,
it appears that the refresh pass is not needed anymore, so it has been removed.

The suggested next release is 3.4.8 in early August.
Feel free to add things in download/release-3.4.8.t2t.

Get rid of old-time depend (and ClockTime in favour of UTCTime).
time-compat helps to retain backward compatibility with directory-1.1
and lower.
