This library provides a FDR-compliant parser, type checker and (experimental) evaluator for machine CSP files.

There is also a program, cspmchecker, that makes use of this library to provide command line type checking.

The simplest method is to install via Hackage. cabal install cspmchecker will install cspmchecker and its dependencies.

Otherwise, if you obtain a source distribution then the following commands will install libcspm.

cabal configure
cabal build
cabal install

To install cspmchecker, firstly install libcspm as above, then change directory to cspmchecker and run the following commands.

cabal configure
cabal build
cabal install

This should make cspmchecker available from your command line shell (if not check that the location cabal installs binaries to is on your $PATH).

From a command line shell simply do cspmchecker file.csp to type check the files. Any error messages will be printed out. For example:

$ cspmchecker ucsexamples/chapter04/abp.csp 
Checking ucsexamples/chapter04/abp.csp.....
ucsexamples/chapter04/abp.csp:80:36-39:
    Couldn't match expected type Int.Int with actual type Int
    In the expression: bit
    In the expression: ack == bit
    In the expression: (ack == bit)

Documentation of the type system is forthcoming.

See http://hackage.haskell.org/package/libcspm for documentation.

To test libcspm run the following commands.

cabal configure --enable-tests
cabal build
cabal test

Please files bug reports at https://github.com/tomgr/libcspm/issues. Please provide a minimal example script that exhibits the error (if possible).
