If you want the fastcgi server, use cabal install -ffastcgi.
This is to avoid problems when you only want to compile pgf-http and the
fastcgi library fails to install, which it usually does, since it depends on
a C library which is not installed automatically with cabal.
The grammars will then by default be fetched from the same server as
minibar.html. This means that everything will be served locally when accessing
minibar through a locally running pgf-http.
Along with the changes to Setup.hs it should now be enough to do
cabal install
pgf-http
open http://localhost:41296/
to run the PGF service locally and play with some example grammars in minibar.
The default binary representation in haskell's Data.Binary package is
homemade and quite complicated. Making it compliant with IEEE 754 will
make it easyer for the java runtimes (and probably others) to load the
PGF.
* The gf command line options -preproc=mkPresent and -preproc=mkMinimal now
refer to internal preprocessors equivalent to lib/src/mkPresent
and lib/src/mkMinimal.
* The temporary file _gf_preproc.tmp is not created when running an
internal preprocessor, unless there is an error, since errors messages
refer to locations in the preprocessed file. (Possibly allowing the rgl
build to be parallelized.)
* After running an external preprocessor, the temporary file is deleted,
unless there was an error.
* (Bug fix) Before, when running more than one preprocessor, the same file name
would be used for both input and output, e.g.,
mkPresent _gf_preproc.tmp > _gf_preproc.tmp
which would result in an empty file being processed. Now, the input and
output files will always be different.
The dependency on the fastcgi package made pgf-server difficult to compile, so
it is now split into
- pgf-fgci (main module in pgf-fcgi.hs), which is built only if fastcgi is
already installed or if you turn on the fastcgi flag (e.g. by doing
'cabal install -f fastcgi').
- pgf-http (main module in pgf-http.hs) which is always built (and hopefully
has no problematic dependencies.)
The modules FastCGIUtils and PGFService no longer depend on fastcgi.
