Direct Observation: Reading STG #14

Open doyougnu opened 2 years ago

doyougnu commented 2 years ago

Should have:

- good patterns
- bad patterns and how to fix them
- description of all information dumped by core
- possibly description of unarisation?
- description of slow_ap and fast_ap and other machine fundamentals
- no-update or update lambda

for this and #13 make sure it connects to the user's vision of their code.

also this guidance for emitting stg for packages:

Maybe if I copy a cabal.project.freeze file from the node into the ouroboros-network repository at that commit, then compile there I should get the same results as the node does, but it seems quite fragile to rely on this

...
One way to make this easier is to locally make it a local package.
Just cabal unpack the-pkg-name which should fetch the tarball from CHAP and adjust your cabal.project to point to the local directory.
