adebfe090c error message tweaks 2023-04-24 23:19:15 +02:00
b74ffa0077 rewrite parser
previously it backtracked too much, so instead of giving a useful
parse error, it just said "expected end of input" at the beginning of
the problem toplevel. which, if it's a namespace, could be way off.
2023-04-24 22:25:04 +02:00
3f06e8d68b allow multiple names in a binder
e.g. "(x y : ℕ) × plus x y ≡ 10 : ℕ"

fixes #2

ac85dc9352 don't put a ∷ℕ on nat literals that's silly 2023-04-17 22:02:40 +02:00
6428d39ce1 semicolons between decls in namespaces 2023-04-17 21:41:00 +02:00
3fb8580f85 re-add tightening and use it when messing with scopes
e.g. "coe [_ ⇒ A] @p @q s" should immediately reduce to "s",
but if the "_ ⇒ A" happened to use an SY it didn't.

this will still happen if a wrong SY sneaks in but the alternative is
re-traversing the term over and over every time whnf runs

5053e9b234 remove inject stuff
injecting from m to (n+m) is just id ::: id ::: ... ::: shift n.
specifically, injecting from 0 is just the shift. so.
