implicit-hie

cd your-stack-or-cabal-package
gen-hie > hie.yaml

gen-hie should be run the root of a cabal or stack project. The config type (cabal or stack) is determined by the existence of dist-newstyle, .stack-work, stack.yaml, if none are found the default is cabal.

Features

All common Cabal and Stack configurations should just work. If you use more advanced features, the generated config may not be complete.

• multi component cabal, stack projects
• multiple executables under a single path
• multiple paths provided to hs-source-dirs
• lookup nested packages in cabal.project or stack.yaml
• Handle Exe and Bench other-modules
• common stanzas
