Comment(by SimonHengel):
Being able to generate import statements with TH would be awesome.
Here is my use case.
Say I have a directory that contains several modules with tests (using
hspec as an example, and assuming that each module exports some
{{{spec}}}):
{{{
test/FooSpec.hs
test/BarSpec.hs
test/BazSpec.hs
}}}
Then I'd like to generate a {{{Main.hs}}} by writing something like this:
{{{
-- test/Main.hs
{-# LANGUAGE TemplateHaskell #-}
import Test.Hspec.TH (autoRun)
$(autoRun)
}}}
Which should expand to.
{{{
-- test/Main.hs
import qualified FooSpec
import qualified BarSpec
import qualified BazSpec
main = hspec $ do
describe "Foo" FooSpec.spec
describe "Bar" BarSpec.spec
describe "Baz" BazSpec.spec
}}}
