On the command line I can do the following:

That is, there is no output on the second call, just as expected. However, I can't work out out to turn off the warning in Vim. AFAIU the following should work:

g:ghcmod_ghc_options = ['-isrc', '-idist/build/autogen', '-fno-warn-missing-signatures']

but it doesn't. I'm obviously missing something, but what?

This was due to my confusion. Once I realised that the markings in Vim wasn't due to the ghc-mod.vim, but due to syntastic it became a lot easier to fix my configuration. In short g:ghcmod_ghc_options = ['-isrc', '-idist/build/autogen', '-fno-warn-missing-signatures'] works fine for controlling the GhcMod* commands. To configure the arguments syntastic pass to ghc-mod use this: g:syntastic_haskell_ghc_mod_args = '-g -fno-warn-missing-signatures' /M -- Magnus Therning OpenPGP: 0xAB4DFBA4 email: magnus@therning.org jabber: magnus@therning.org twitter: magthe http://therning.org/magnus You do not examine legislation in the light of the benefits it will convey if properly administered, but in the light of the wrongs it would do and the harms it would cause if improperly administered. -- Lyndon Johnson
