[Haskell-cafe] mueval leaving behind tmp files

[Johannes Waldmann]

The following program prints   Right ("test","Bool","True")
as it should, but it leaves behind in /tmp 
two files (name is a long string of digits)
and an empty directory (name is ghcNNNNN_N).
... and it deletes the input file (/tmp/Main.hs).

That's not nice. Ideally, I would want to read input
from a String (instead of the file), and not write to disk at all.
But cleaning up properly would be OK as a work-around.


import Language.Haskell.Interpreter
import Mueval.Interpreter
import Mueval.ArgsParse

main = do
    writeFile "/tmp/Main.hs" "test = True"
    result <- runInterpreter $ interpreter $ Options 
        { timeLimit =1, modules =Just ["Prelude"], expression ="test"
        , loadFile ="/tmp/Main.hs", user="what", printType =True
        , extensions =False,namedExtensions = []
        , noImports =False, rLimits =False, help=True
        }
    print result
