a8ac6f11f7 fix a quantity in CaseBox 2024-02-28 16:49:15 +01:00
325e128063 add η for False and True 2024-02-10 11:39:07 +01:00
7afcbfe258 recognise nats other than 0 in eq checker 2023-12-21 17:48:12 +01:00
03c197bd04 add local bindings to context
- without this, inside the body of `let x = e in …`, the typechecker
  would forget that `x = e`
- now bound variables can reduce, if they have a definition, so RedexTest
  needs to take the context too

instead of as huge `succ (succ (succ ⋯))` terms

e6c06a5c81 pass the subject quantity through equality etc
in preparation for non-linear η laws
2023-09-18 21:53:38 +02:00
3fe9b96f05 make function types with an empty domain subsingletons
this is useful for the base cases of W types when i try those again

add2eb400c make Elim.compare0 able to pass a type to isSubSing
it now recovers from (most) errors and always returns a type, so that
isSubSing doesn't have to recalculate it

it already assumed the inputs had the same type. now it just leans on
that assumption harder
2023-08-28 20:00:54 +02:00
72609bc12f Elim.compare0 infers the type
instead of calling computeElimType over and over. now there's just one
at the start

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.
