Executing `cabal repl` with top-level functions

Question

I am trying to learn how to isolate my Haskell projects with cabal.

I use the command interpreter extensively ghci

, which imports top level functions by default.

cabal repl

also provides a shell, but top-level functions are not imported.

How can I run cabal repl

so that top-level constants and functions are defined in the shell?

Here's a minimal example:

-- somefile.hs
someConstant :: Int
someConstant = 5

main :: IO ()
main = undefined

someConstant

Will now be defined at startup ghci somefile.hs

, but it will not be defined when I run cabal repl

.

If the module is listed in your project (i.e. in sections with open modules or other modules):

:m *ModuleName

Otherwise:

:l somefile.hs
