Some commands (linearize, linearizeAll, random, generate, translate and
translategroup) by default produce output in all languages supported by the
grammar and the 'to' parameter could be used to restrict output to a single
language. Now you can restrict the output to a list of languages. Languages
should be separated by spaces.
Also removed an unnecessary LANGUAGE pragma and reduced code verbosity.
This should prevent errors like
Internal error in Compute.ConcreteNew:
Applying Predef.drop: Expected a value of type String, got VFV [VString "gewandt",VString "gewendet"]
Fixes the following build failure:
src/runtime/haskell/Data/Binary/IEEE754.lhs:256:17:
Could not deduce (Num a) arising from a use of `mask'
from the context (Bits a)
bound by the type signature for
clamp :: Bits a => BitCount -> a -> a
The sequence operator (x+y) was implemented by splitting the string to be
matched at all positions and trying to match the parts against the two
subpatterns. To reduce the number of splits, we now estimate the minimum and
maximum length of the string that the subpatterns could match. For common
cases, where one of the subpatterns is a string of known length, like
in (x+"y") or (x + ("a"|"o"|"u"|"e")+"y"), only one split will be tried.
GF produced slightly different PGF files on 64-bit systems and 32-bit systems.
This could cause problems when a PGF was produced on a 32-bit system and used
on a 64-bit system.
To fix this, the GF compiler and the Haskell PGF run-time library now reads
and writes PGF files like the 32-bit version even when compiled on a 64-bit
system.
Note: the Haskell type Int is still used internally in GF, which could be
32 bits or 64 bits...
The parser works on raw byte sequences read from source files. If parsing
succeeds the raw byte sequences are converted to proper Unicode characters
in a later phase. But the parser calls the function buildAnyTree, which can
fail and generate error messages containing source code fragments, which might
then containing raw byte sequences. To render these error messages correctly,
they need to be converted in accordance with the coding flag in the source
file. This is now done for UTF-8-encoded source files, but should ideally also
be done for other character encodings. (Latin-1-encoded files never suffered
from this problem, since raw bytes are proper Unicode characters in this case.)
+ Instead of "Internal error in ...", you now get a proper error message with
a source location and a function name.
+ Also added some missing error value propagation in the partial evaluator.
+ Also some other minor cleanup and error handling fixes.
