In this initial commit, I have done the following:
- Added unit tests to roc_parse's ident.rs file to cover at least the
simplest Ident enum cases (Tag, OpaqueRef, and simple Access)
- Added '_' as a valid "rest" character in both uppercase and lowercase
identifier parts
- Updated the test_syntax snapshots appropriately
There is still a lot left to do here. Such as:
- Do we want to allow multiple '_'s to parse successfully?
- Handle qualified access
- Handle accessor functions
- Handle record update functions
- Remove the UnderscoreInMiddle case from BadIdent
- Write unit tests for Malformed Idents
I am not a "Rustacean" by any means, but have been through the Book in
years past. Any feedback on the way I wrote the tests or any other part
of the implementation would be very appreciated.
