This project can be built with either Stack or Cabal. For historical reasons, we generate a `cabal.project` from the `stack.yaml`, and we do not commit the former to the repo, to have a single "source of truth".
However, it's always possible to generate a `cabal.project` thanks to [stack2cabal](https://hackage.haskell.org/package/stack2cabal).

### Working on libraries
When a devlopment is needed on libraries (for instance, the HAL crawler in https://gitlab.iscpif.fr/gargantext/crawlers):
1. Ongoing devlopment (on local repo):
1. In `cabal.project`:
- add `../hal` to `packages:`
- turn off (temporarily) the `hal` in `source-repository-package`
2. When changes work and tests are OK, commit in repo `hal`
2. When changes are commited / merged:
1. Get the hash id, and edit `stack.yaml` with the **new commit id**
2. run `./bin/update-cabal-project`
- get an error that sha256 don't match, so update the `./bin/update-cabal-project` with new sha256 hash
- run again `./bin/update-cabal-project` (to make sure it's a fixed point now)
> Note: without `stack.yaml` we would have to only fix `cabal.project` -> `source-repository-package` commit id. Sha256 is there to make sure CI reruns the tests.
