Introduction

This packages provides lightweight nix shells for general haskell development with cabal.

GHC Support Matrix

The below matrix shows how well a particular GHC version is supported. Legend:

• 🌕: Support exists with good caching.
• 🌓: Support exists with poor caching.
• 🌑: Support does not exist.

GHC versions that support all tools and have fast caching are bolded. In the interest of brevity, only the latest 3 major versions are listed. Older versions are listed in the collapsed table below.

GHC	Caching	apply-refact	fourmolu	hlint	hls	ormolu
9.6.1	🌓	🌕	🌕	🌕	🌕	🌕
9.6.2	🌕	🌕	🌕	🌕	🌕	🌕
9.6.3	🌕	🌕	🌕	🌕	🌕	🌕

Shells

This section lists the provided shells. For shells with arguments, the default value (if any) is listed in parentheses.

Common Args

• apply-refact (false)
• fourmolu (false)
• ghc-vers
• ormolu (false)
• hlint (false)
• hls (false)

Default

Attr: default

Description: Nix shell for general haskell development. Most packages can use this shell. Includes cabal and ghc. Note that there is no guarantee every dev tool will work with every ghc-vers. In particular, there will often be a lag time before the latest GHCs are fully supported.

The default ghc is the latest version that works with every tool and has decent nix caching.

Args:

• apply-refact
• fourmolu
• ghc-vers (ghc982)
• hlint
• hls
• ormolu

Usage:

nix-shell http://github.com/tbidne/hs-nix-shells/archive/main.tar.gz -A default

nix-shell http://github.com/tbidne/hs-nix-shells/archive/main.tar.gz -A default \
  --argstr ghc-vers ghc925 \
  --arg hls true

LiquidHaskell

Attr: liquidhaskell

Description: Nix shell for LiquidHaskell. Includes cabal, ghc, and the z3 smt solver.

Args:

• ghc-vers
• hlint
• hls

Usage:

nix-shell http://github.com/tbidne/hs-nix-shells/archive/main.tar.gz -A liquidhaskell
