packs

WIP: Rust implementation of packs for ruby

Initial Milestone

• [ ] packs generate_cache, which can be used to update tmp/cache/packwerk for faster packwerk output. It should produce the exact same json that packwerk produces today. Challenges include:
  • [ ] Parsing ERB
  • [ ] Parsing Rails associations and rewriting them as constant references using a pluralizer. Initially, non-standard inflections will likely not be supported (although I may support it through hard-coded map in packwerk.yml)
  • [ ] Replicating packwerk's behavior with respect to not recording "local definitions"
• [ ] packs check, which can be used as a drop-in replacement to the VSCode
• [ ] packs update, which can be used to update deprecated_references.yml
• [ ] packs lsp, to launch an LSP-server to provide faster feedback
