The command "gf -server" now starts a simple HTTP server on port 41295,
providing a simple web API to the GF compiler. It currently support the
follwing operations:
* creating new temporary directories for grammar uploads,
* uploading grammars files for use in the GF shell,
* executing GF shell commands, and
* accessing static files.
This means that GF now depends on some additional networking related packages,
but they should be available and easy to install on all platforms. There is
also a new configuration flag "server" in gf.cabal, so GF will be compiled
without support for server mode if the extra packages are unavailable.
Note that running gf -server while connected to the internet can be a security
risk. To prevent unauthorized access to the rest of the system, it is
advisable to run the server in GF_RESTRICTED mode and as a user with suitably
restricted file permissions.
I changed the version number to 3.2.1-darcs.
I think the version number of the current version from darcs should always
include the "-darcs" suffix (or "-current" perhaps?). The suffix should be
removed only momentarily when making an official release.
The version of cabal distributed with Ubuntu 10.10 is too old to handle
executables that refer to the library in the same package, so to not make it
too complicated for Ubuntu users to compile GF from source, pgf-http is no
longer part of the main gf.cabal. :-(
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.
