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.
This is a work in progress, but usable as it is now.
Some memory leaks and segfaults to be expected.
The files are
CRuntimeFFI.hsc -- user-friendly functions, almost the same as in the real Haskell PGF library.
Gu.hsc -- mindlessly copypasted functions from various files in gu/
PgfLow.hs -- mindlessly copypasted functions from various files in pgf/
The first two files (.hsc) use some special constructions for accessing C objects from Haskell.
See the syntax here: http://www.haskell.org/ghc/docs/7.2.1/html/users_guide/hsc2hs.html
HOW TO COMPILE:
hsc2hs Gu.hsc CRuntimeFFI.hsc -v --cflag="-std=c99" && ghc -lpgf -lgu --make CRuntimeFFI
HOW TO USE:
- Symlink or copy the files in this directory to the directory you're working with; these files are not included in any makefiles
- Import CRuntimeFFI to a Haskell program you're writing
module Main where
import CRuntimeFFI
- Use the functions in your program
main = do
pgf <- readPGF "Foo.pgf"
let english = getConcr pgf (mkCId ("FooEng"))
I haven't managed to make it work in ghci, get errors about unknown symbols (low level C functions).
