# This is a manually-written expression over an in-tree cabal file.
|
||
# It's awkward but this way allows the package user to pass in
|
||
# extraPackages without much extra hassle on their end, similarly how
|
||
# the XMonad service handles it: the difference is that we don't have
|
||
# anything like XMONAD_GHC…
|
||
#
|
||
# The idea is that the user changes their configs using any libraries
|
||
# he likes and then builds it using this expression. Once that's done,
|
||
# ‘reload’ and similar functions should all work as long as the user
|
||
# doesn't need new libraries at which point they should add them to
|
||
# extraPackages and rebuild from the expression.
