runghc allows you to run Haskell programs without first having to compile them.
The runghc commandline looks like:
runghc [runghc flags] [GHC flags] module [program args]
The runghc flags are
which tells runghc which GHC to use to run the program,
--help, which prints usage information. If it is
not given then runghc will search for GHC in the directories in the
system search path.
runghc will try to work out where the boundaries between
[runghc flags] and
[GHC flags], and
[program args] and
module are, but you can use a
-- flag if it doesn't get it right. For example,
runghc -- -fwarn-unused-bindings Foo means runghc
won't try to use
warn-unused-bindings as the path to GHC,
but instead will pass the flag to GHC. If a GHC flag doesn't start
with a dash then you need to prefix it with
--ghc-arg= or runghc will think that it is the
program to run, e.g.
runghc -package-db --ghc-arg=foo.conf Main.hs.
