## TODO
|
||
|
||
- [ ] Check for shadowing when declaring dcon
|
||
- [ ] Require infix decl before declaring names
|
||
- [x] Allow unicode operators/names
|
||
- [ ] Web tool
|
||
- edit, view output, view js, run js, monaco would be nice.
|
||
- need to shim out Buffer
|
||
- [x] get rid of stray INFO from auto resolution
|
||
- [ ] handle `if_then_else_` style mixfix
|
||
- [ ] Search should look at context
|
||
- [ ] records
|
||
- [ ] copattern matching
|
||
- [ ] Support @ on the LHS
|
||
- [ ] Get `Combinatory.newt` to work
|
||
- [x] Remember operators from imports
|
||
- [ ] Default cases for non-primitives (currently gets expanded to all constructors)
|
||
- This may need a little care. But I think I could collect all constructors that only match wildcards into a single case. This would lose any information from the individual, unnamed cases though.
|
||
- There are cases where we have `_` and then `Foo` on the next line, but they should all get collected into the `Foo` case. I think I sorted all of this out for primitives.
|
||
- [x] Case for primitives
|
||
- [ ] aoc2023 translation
|
||
- [x] day1
|
||
- [x] day2
|
||
- some "real world" examples
|
||
- [x] Maybe Eq and stuff would work for typeclass without dealing with unification issues yet
|
||
- [x] unsolved meta errors repeat (need to freeze or only report at end)
|
||
- [x] Sanitize JS idents, e.g. `_+_`
|
||
- [x] 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)
|
||
- [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)
|
||
- [ ] `data` sugar: `data Maybe a = Nothing | Just a`
|
||
- [x] matching on operators
|
||
- [x] top level
|
||
- [x] case statements
|
||
- [ ] Lean / Agda ⟨ ⟩
|
||
- [ ] Lean-like .map, etc? (resolve name in namespace of target type, etc)
|
||
- [x] ~~SKIP list syntax~~
|
||
- Agda doesn't have it, clashes with pair syntax
|
||
- [ ] autos / typeclass resolution
|
||
- [x] very primitive version in place, not higher order, search at end
|
||
- [x] monad is now working
|
||
- [x] do blocks (needs typeclass, overloaded functions, or constrain to IO)
|
||
- [x] 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 them in codegen)
|
||
- [x] vscode: syntax highlighting for String
|
||
- [ ] add `pop` or variant of `pfunc` that maps to an operator, giving the js operator and precedence on RHS
|
||
|
||
### Parsing
|
||
|
||
- [ ] consider allowing σ etc in identifiers
|
||
- Probably need to merge oper / ident first and sort out mixfix in parsing
|
||
- The mixfix parsing can handle this now, need to update lexing.
|
||
- [ ] Parse error not ideal for `\x y z b=> b` (points to lambda)
|
||
|
||
### Background
|
||
|
||
- [ ] Read Ulf Norell thesis
|
||
- [ ] Finish reading dynamic pattern unification paper to see what is missing/wrong with the current implementation
|
||
|
||
### Other issues
|
||
|
||
- [ ] Name space flattening makes it a bit more subtle when a misspelled (or shadowed) constructor turns into a variable.
