Touching preprocessor modules (alex, happy, c2hs) doesn't trigger a rebuild #479
Description
Steps to reproduce:
new-template.cabal:
name: new-template
version: 0.1.0.0
build-type: Simple
cabal-version: >= 1.10
library
exposed-modules: A, B, C, D
build-depends: base >= 4.7 && < 5, array
default-language: Haskell2010
ghc-options: -fno-warn-tabs
stack.yaml:
flags: {}
packages:
- '.'
extra-deps: []
resolver: nightly-2015-06-28A.hs:
module A whereB.chs:
module B whereC.x:
{
module C where
}
%wrapper "basic"
tokens :-
[\ ] ;
{
}D.y:
{
module D where
}
%name parse
%tokentype { () }
%token
'()' { () }
%%
Unit : '()' { () }
{
happyError = undefined
}Expected:
touching any of the four modules triggers a rebuild.
Actual:
