Hi Michael,

For those wanting to have direct access to GHC and other such tools, without needing to prefix calls with `stack exec -- `, the following added to your ~/.bashrc (or equivalent) will do the trick:
export PATH=`stack path --bin-path`
This is not the side-effect-free function I expected it to be. I just tried it on a Mac after a new install of stack:
$ stack path --bin-path Run from outside a project, using implicit global project config Using resolver: lts-7.0 from implicit global project's config file: ~/.stack/global-project/stack.yaml Fetched package index. Populated index cache. No compiler found, expected minor version match with ghc-8.0.1 (x86_64) (based on resolver setting in /Users/leather/.stack/global- project/stack.yaml). Try running "stack setup" to install the correct GHC into ~/.stack/programs/x86_64-osx/
The above took nearly 10 minutes and failed. I would not recommend doing that in a ~/.bashrc.
See https://github.com/commercialhaskell/stack/issues/2325 for the issue I reported in July.

That's a fair point, but if the user first runs `stack setup` (which I'd recommend in any usage of this line), it does become side-effect-free. Regarding #2325: it might make sense to have `stack path` simply fail if no project file is found, but user intent is a bit unclear on that point. Michael
