Haskell+Windows: custom location
Haskell+Windows: custom location
Often today we need to install Haskell on Windows in not-default location - due
to SSD disks, for example, in D:\somewhere instead of standard C:\. This
tutorial shows how to do it.
!Install stack
First, we need to install stack in non-typical location. Create directory
D:\stackroot - all stack caches will be located there. Then add to environment
variable binding STACK_ROOT=D:\stackroot. Install stack also on the same disk,
for example, D:\apps\stack (or put in there if use download binary).
Now install the compiler as usual. After installation you will call stack with
--system-ghc. Another (and right!) solution is to add next setting in
D:\stackroot\config.yaml:
local-bin-path: D:\apps\haskell\8.0.2\bin system-ghc: true
I suppose you installed compiler in D:\apps\haskell (and it has version
8.0.2). If not, change value to your path.
Also you should add to environment variable PATH next path:
d:\apps\haskell\8.0.2\msys\usr\bin.
Now you can use stack to install other packages even which needs ./configure
script run.
To check what paths uses stack, run stack path.
!Integration with Spacemacs
Install with stack packages:
- apply-refact
- hlint
- stylish-haskell
- hasktags
- hoogle (for local queries)
- ghc-mod
- intero (optional, because intero-layer install it byself)
- hindent
In Spacemacs you should to add Haskell layer. To see types hints you must run Haskell REPL (SPC m h s b IMHO:). Also you must add syntax-checking layer, auto-completion. And sure, path to stack must be in PATH environment variable :)
