If so, just great .. a ton of code. ;^(
No, you don't have to look for this. It is in the code snippet you sent:
swishParse :: String -> String -> SwishStateIO (Maybe RDFGraph)
swishParse fnam inp =
do { fmt <- gets $ format
; case fmt of
N3 -> swishParseN3 fnam inp
otherwise ->
do { swishError ("Unsupported file format: "++(show
fmt)) 4
; return Nothing
}
}
In the case expression you use "otherwise" as a variable. But you do not
use that variable in that branch. Hence the warning:
Swish/HaskellRDF/SwishCommands.hs:304:12:
Warning: Defined but not used: `otherwise'
This has nothing to do with someone else shadowing the definition of
"otherwise".
Ciao,
Janis.
