* Add better support for Haskell stack compiler tools
This commit adds support for `stack` as the executable of a tool. This
follows a pattern that has been implemented for `bundler`'s tool chain.
* Move hlint command to linter file
* Add vader test for stack exec handling
* Update ghc-mod to support stack execution
`ghc-mod` was previously broken into 2 linters.
1. ghc_mod
2. stack_ghc_mod
This additional linter is not necessary with proper support for
executable variables and `stack exec` handling.
* Support stack exec in hfmt
* Support stack in hdevtools
* Add stylish-haskell as a fixer
`stylish-haskell` is a common formatting tool for the haskell toolchain.
It is not as advanced as `brittany` or `hindent`, but it is commonly
used for formatting of imports and data declarations. This adds it as a
fixer in ALE.
* Adding support for haskell-ide-engine
* Work with the current directory if no stack.yaml file is found
* Added Cabal file detection, updated documentation and added tests
* Updated help
* Vim scripts shouldn't have hyphens
Especially not ones that will be autoloaded. You can't have a hyphen in
a function name, so autoloading functions based on filename will fail.
* Add g:haskell_stack_build_options, default: --fast
If we're going to use the --fast option, we may as well go the whole 9
yards and let the user configure the 'stack build' flags.
* Create documentation for stack-build options
