Documentation

data Program

Represents a program which cabal may call. Constructors Program programName :: String The simple name of the program, eg ghc programBinName :: String The name of this program's binary, eg ghc-6.4 programArgs :: [String] Default command-line args for this program programLocation :: ProgramLocation Location of the program. eg. /usr/bin/ghc-6.4 Instances Read Program Show Program

data ProgramLocation

Similar to Maybe, but tells us whether it's specifed by user or not. This includes not just the path, but the program as well. Constructors EmptyLocation UserSpecified FilePath FoundOnSystem FilePath Instances Read ProgramLocation Show ProgramLocation

data ProgramConfiguration

Constructors ProgramConfiguration (Map String Program) Instances Read ProgramConfiguration Show ProgramConfiguration

withProgramFlag :: Program -> String

The flag for giving a path to this program. eg --with-alex=/usr/bin/alex

programOptsFlag :: Program -> String

The flag for giving args for this program. eg --haddock-options=-s http://foo

programOptsField :: Program -> String

The foo.cabal field for giving args for this program. eg haddock-options: -s http://foo

defaultProgramConfiguration :: ProgramConfiguration

The default list of programs and their arguments. These programs are typically used internally to Cabal.

updateProgram :: Maybe Program -> ProgramConfiguration -> ProgramConfiguration

Update this program's entry in the configuration. No changes if you pass in Nothing.

userSpecifyPath

:: String Program name -> FilePath user-specified path to filename -> ProgramConfiguration -> ProgramConfiguration User-specify this path. Basically override any path information for this program in the configuration. If it's not a known program, add it.

userSpecifyArgs

:: String Program name -> String user-specified args -> ProgramConfiguration -> ProgramConfiguration User-specify the arguments for this program. Basically override any args information for this program in the configuration. If it's not a known program, add it.

lookupProgram :: String -> ProgramConfiguration -> IO (Maybe Program)

Looks up a program in the given configuration. If there's no location information in the configuration, then we use IO to look on the system in PATH for the program. If the program is not in the configuration at all, we return Nothing. FIX: should we build a simpleProgram in that case? Do we want a way to specify NOT to find it on the system (populate programLocation).

lookupPrograms :: ProgramConfiguration -> IO [(String, Maybe Program)]

rawSystemProgram

:: Int Verbosity -> Program The program to run -> [String] Any extra arguments to add -> IO () Runs the given program.

rawSystemProgramConf

:: Int verbosity -> String The name of the program to run -> ProgramConfiguration look up the program here -> [String] Any extra arguments to add -> IO ()
