## TODO
|
||
|
||
- [ ] unsolved meta errors repeat (need to freeze at some point)
|
||
- [x] Sanitize JS idents, e.g. `_+_`
|
||
- [ ] Generate some programs that do stuff
|
||
- [x] import
|
||
- [ ] consider making meta application implicit in term, so its more readable when printed
|
||
- Currently we have explicit `App` surrounding `Meta` when inserting metas. Some people
|
||
leave that implicit for efficiency. I think it would also make printing more readable.
|
||
- When printing `Value`, I now print the spine size instead of spine.
|
||
- [x] eval for case (see order.newt)
|
||
- [ ] dynamic pattern unification (add test case first)
|
||
- Possibly the cause of issue in code commented out in `TestCase4.newt`
|
||
- [x] switch from commit/mustWork to checking progress
|
||
- [x] type constructors are no longer generated? And seem to have 0 arity.
|
||
- [x] raw let is not yet implemented (although define used by case tree building)
|
||
- [x] there is some zero argument application in generated code
|
||
- [x] get equality.newt to work
|
||
- [x] broken again because I added J, probably need to constrain scrutinee to value
|
||
- [x] inline metas. Maybe zonk after TC/elab
|
||
- [x] implicit patterns
|
||
- [x] operators
|
||
- [x] pair syntax (via comma operator)
|
||
- [x] matching on operators
|
||
- [x] top level
|
||
- [x] case statements
|
||
- [x] SKIP list syntax
|
||
- Agda doesn't have it, clashes with pair syntax
|
||
- [ ] autos / typeclass resolution
|
||
- We need special handling in unification to make this possible
|
||
- options
|
||
- keep as implicit and do auto if the type constructor is flagged auto
|
||
- keep as implicit and mark auto, behavior overlaps a lot with implicit
|
||
- have separate type of implict with `{{}}`
|
||
- `TypeClass.newt` is the exercise for this
|
||
- [ ] do blocks
|
||
- [ ] some solution for `+` problem (classes? ambiguity?)
|
||
- [x] show compiler failure in the editor (exit code != 0)
|
||
- [x] write output to file
|
||
- uses `-o` option
|
||
- [ ] detect extra clauses in case statements
|
||
- [ ] add test framework
|
||
- [ ] decide what to do for erasure
|
||
- [ ] type at point in vscode
|
||
- [ ] repl
|
||
- [ ] LSP
|
||
- [x] don't match forced constructors at runtime
|
||
- I think we got this by not switching for single cases
|
||
- [ ] magic nat (codegen as number with appropriate pattern matching)
|
||
- [ ] magic tuple? (codegen as array)
|
||
- [ ] magic newtype? (drop in codegen)
|
||
- [ ] records / copatterns
|
||
- [ ] vscode: syntax highlighting for String
|
||
|
||
### Parsing
|
||
|
||
- [ ] consider allowing σ etc in identifiers
|
||
- Probably need to merge oper / ident first and sort out mixfix in parsing.
|
||
|
||
### Background
|
||
|
||
- [ ] Read Ulf Norell thesis
