## how to build the project with nix dependencies:
#
# 1. start a nix shell (e.g. `nix-shell -j 20`, this uses 20 jobs to fetch deps)
# 2. run `yarn` to install npm deps
# 3. run `install-purs-packages` if you want dependencies locally, available for psc-package and for inspection
# 4. run `build-purs` to build from local sources. otherwise use `build-purs-from-store`.
#
# note that the purescript compiler uses filepaths and timestamps, so using the above two commands
# interchangeably will lead to constant rebuilding of the entire project.
#
## how to update purs-packages.nix
#
# 1. run `soba insdhall` to generate packages.json
# 2. run `soba nix` to generate a nix derivation from packages.json
