New description:
I am loading a target with actual contents (targetContents=Just (contents,
time)). The contents are literate Haskell. I get compilation errors
instead of the "preprocessing needed, interactive check disabled" error I
should get. It works if I manually set the Phase to Unlit `HsSrcFile`, but
the doc says it should guess it's literate from the file extension. I'm
using 6.10.4 in Windows.
`GHC.hs` line 2240:
{{{
Nothing <- mb_phase, Unlit _ <- startPhase src_fn = True[[BR]]
}}}
(src_fn is the file name, endings in .lhs in my case)[[BR]]
`DriverPhase.hs` line 146:
{{{
startPhase "lhs" = Unlit HsSrcFile[[BR]]
}}}
Somewhere in there we forgot to move from "/drive/dir/foo.lhs" to "lhs".
We need something like tail $ takeExtension $ src_fn, and handling
gracefully the case where there is no extension.[[BR]]
I can try to actually code the patch, but I've never tried to build GHC on
my machine....
