# implicit-hie
```bash
cd your-stack-or-cabal-package
stack install implicit-hie # or cabal install implicit-hie
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.
You can use `--cabal`, or `--stack` options to override config type.
# Cabal Multi project example
```bash
❯ git clone https://github.com/well-typed/optics.git
❯ cd optics
❯ gen-hie
cradle:
cabal:
- path: "indexed-profunctors/src"
component: "lib:indexed-profunctors"
- path: "optics-th/src"
component: "lib:optics-th"
- path: "optics-th/tests"
component: "optics-th:test:optics-th-tests"
- path: "optics-vl/src"
component: "lib:optics-vl"
- path: "codegen/./Subtypes.hs"

## Features
All common Cabal and Stack configurations should just work.
If you use more advanced features, the generated config may not be complete.
- [x] multi component cabal, stack projects
- [x] multiple executables under a single path
- [x] multiple paths provided to `hs-source-dirs`
- [x] lookup nested packages in `cabal.project` or `stack.yaml`
- [x] Handle Exe and Bench `other-modules`
- [ ] common stanzas
