From looking at Yi's code, there seems to be a hard-coded list of arguments to pass to ghc. A hack would be to recompile Yi with the arguments to use a different package database...

You may be able to create a 'ghc' shell script that invokes (the real) ghc with the correct --package-conf for Yi, then make a Yi script that sets up a custom path so that it finds your ghc script first. Lots of "ifs", but at least you wouldn't have to maintain a Yi fork :) --Rogan

More precisely, I'm trying to run yi in its own sandbox, created by cabal-dev.

yi uses dyre to recompile its config file. Unsurprisingly, this fails, since ghc doesn't know anything about the yi install unless pointed to a separate package database.

I'm not familiar with dyre, is there any way to tell it to use a specific package database? That *sounds* like it's the problem (since that's the bulk of what cabal-dev does... it establishes a fresh package db and hides the user db).

Has anyone gotten a similar setup to work, or does anyone have any suggestions?
