Sprouting - This is a zettelkasten-style card about a concept I’m interested in remembering.
What I’m calling a project workbook_ is a Livebook notebook used for interactively developing a project, basically in place of using iex -S mix. I’ve found this is easier to work with since it stores the history better.
Importing the project can be done with this “install” block:
app_root = Path.join(__DIR__, ".")
Mix.install(
[
# Add dependencies here
],
# Add this line if it makes sense to use it
config_path: Path.join(app_root, "config/config.exs"),
lockfile: Path.join(app_root, "mix.lock"),
# If you implement any protocols in your project, you'll need this
# though it might have a performance impact.
consolidate_protocols: false
