are you proposing that a reasonable workaround in my use case is to do :cd .. :r this seems like a reasonableish approach, or was there a different example you had in mind?

Yes, that is what I had in mind. The typical scenario for me is to be editing a file in emacs, C-c-C-l it, and have GHCi complain. I then issue a ":cd .." in GHCi, and my subsequent loads are properly rooted at top of the project directory.

The fundamental problem is that ghci has no concept of "projects". The correct place for this is in Cabal, which *does* have project support, but as yet it has no support for ghci. It's conceivable that the ghci user commands capability could be used to find (and optionally) parse a *.cabal file to identify a package root, at the price of an initial slowdown if you didn't have one. - -- brandon s. allbery [linux,solaris,freebsd,perl] allbery@kf8nh.com system administrator [openafs,heimdal,too many hats] allbery@ece.cmu.edu electrical and computer engineering, carnegie mellon university KF8NH -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.10 (Darwin) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAkxDXB0ACgkQIn7hlCsL25WqagCg1Z9yJunJObDQWj27awIjZgNF 420AoNFoW3O75O1VOOP7lzXOVW7iMtjZ =jaTS -----END PGP SIGNATURE-----
