`-DGHCJS_BROWSER` flag for stack build doesn't do anything

[sylwiabr]

I was trying to go through the tutorial http://edsko.net/2015/02/14/atom-haskell/ with stack instead of ghcjs. The Issue ghcjs/ghcjs#302 describing ghcjs not working with Atom if it is used without -DGHCJS_BROWSER is still open so it is not possible to write ghcjs Atom plugins using stack.

Steps to reproduce

For minimal example - "hello world" program - comparision all.js outputs created with and without -DGHCJS_BROWSER flag doesn't show any difference.

$ stack build --ghc-options="-DGHCJS_BROWSER" --verbose

Stack version

$ stack --version
Version 1.2.0 x86_64 hpack-0.14.0

Method of installation

brew

[mgsloan]

The 1st log looks like a build that has no work to do, because it had probably already been built. The 2nd log contains a configure invocation

Ghc-options are indeed not yet handled perfectly. It is not currently possible to reliably apply a flag to every single package involved in the build. See #849

I hesitate to recommend this as it might be a big waste of time, but if you wipe away your ~/.ghcjs and your $STACK_ROOT/snapshots folder, and always build with

ghc-options:
  "*": -DGHCJS_BROWSER

It should work out.

[sylwiabr]

Because deleting .ghcjs and $STACK_ROOT/snapshots didn't work I created virtual machine with freshly installed system and did the experiment again:

• install stack from brew
• create new project with -DGHCJS_BROWSER flag in stack.yaml file
• stack setup
• stack build
  log.txt
  but it didn't work again. Are there any issues on macOS El Capitan?

[sylwiabr]

ok, so -DGHCJS_BROWSER flag should go into .cabal file, not stack.yaml

[wdanilo]

For me this looks like a bug, when a flag works in .cabal but doesnt in stack.yaml. Should be re-opened imo @mgsloan .

[mgsloan]

@wdanilo Good point! I believe this is already fixed in master - see #2714
