Connect a Feldspar function between serializable types to stdin/stdout. The inputoutput will be in the form of a list as recognized by toHaskell fromHaskell (i.e. the length followed by the elements in sequence).

The function will be mapped over the input list in a lazy manner.

marshalled'

Arguments

:: (MarshalFeld a, MarshalFeld b)

=> CompilerOpts

-> ExternalCompilerOpts

-> (a -> Run b)

Function to compile

-> ((HaskellRep a -> IO (HaskellRep b)) -> IO c)

Function that has access to the compiled executable as a function

-> IO c

A version of marshalled that takes ExternalCompilerOpts as additional argument

marshalled

Arguments

:: (MarshalFeld a, MarshalFeld b)

=> (a -> Run b)

Function to compile

-> ((HaskellRep a -> IO (HaskellRep b)) -> IO c)

Function that has access to the compiled executable as a function

-> IO c

Compile a function and make it available as an IO function. Note that compilation only happens once, even if the function is used many times in the body.

For example, given the following Feldspar function:

sumArr :: DIArr Int32 -> Run (Data Int32)
sumArr arr = do
    r <- initRef 0
    for (0,1,Excl $ length arr) $ \i -> modifyRef r (+ arrIx arr i)
    unsafeFreezeRef r

marshalled can be used as follows:

*Main> marshalled sumArr $ \f -> (f [3,4,5] >>= print) >> (f [6,7,8,9] >>= print)

marshalledStream'

Arguments

:: (MarshalFeld a, MarshalFeld b)

=> CompilerOpts

-> ExternalCompilerOpts

-> (a -> Run b)

Function to compile

-> (([HaskellRep a] -> IO [HaskellRep b]) -> IO c)

Function that has access to the compiled executable as a function

-> IO c

A version of marshalledStream that takes ExternalCompilerOpts as additional argument

marshalledStream

Arguments

:: (MarshalFeld a, MarshalFeld b)

=> (a -> Run b)

Function to compile

-> (([HaskellRep a] -> IO [HaskellRep b]) -> IO c)

Function that has access to the compiled executable as a function

-> IO c

Compile a function and make it available as an IO function. The compiled function will be applied repeatedly over the list of inputs producing a list of outputs. Note that compilation only happens once, even if the function is used many times in the body.
