| * | Remove extra attributes for elimination rules, unneeded for now. | Josh Chen | 2018-07-06 | 3 | -5/+2 |
| | | |||||
| * | Added attributes to type elimination rules, not sure if these will actually ↵ | Josh Chen | 2018-07-06 | 7 | -29/+110 |
| | | | | | be needed or useful later. Added [comp] attribute to be used by simplification met methods. | ||||

| * | Removed all [simp] attributes, these will be added later when I set up the ↵ | Josh Chen | 2018-06-18 | 3 | -31/+51 |
| | | | | | simplifier. Proved simplification rule for dependent fst. | ||||
| * | Proof of projection functions now harder. Should look up automation methods. | Josh Chen | 2018-06-17 | 2 | -9/+15 |
| | | |||||
| * | Eliminators must be completely parametrized at the meta-level. | Josh Chen | 2018-06-17 | 1 | -14/+5 |
| | | |||||
| * | Decided on a new proper scheme for type rules using the idea of implicit ↵ | Josh Chen | 2018-06-17 | 3 | -24/+45 |
| | | | | | well-formed contexts and guaranteed conclusion well-formedness. Product type rules now follow this scheme. | ||||

| * | Proved that the inductor on Sum has the correct type. | Josh Chen | 2018-06-05 | 2 | -44/+81 |
| | | |||||
| * | Dependent sum done, I think. | Josh Chen | 2018-06-05 | 2 | -28/+42 |
| | | |||||
| * | Prod_comp should have a type constraint. This also fixes a false proof for ↵ | Josh Chen | 2018-06-04 | 2 | -36/+69 |
| | | | | | the dependent sum projection functions. | ||||
| * | Should be final version of Prod. Theorems proving stuff about currying. ↵ | Josh Chen | 2018-06-01 | 2 | -41/+65 |
| | | | | | Rules for Sum, going to change them to use object-level arguments more. | ||||

| * | More rigorous rules for Product type. Propositions and proofs all working, ↵ | Josh Chen | 2018-05-29 | 2 | -24/+72 |
| | | | | | but have to think about maybe relaxing the computation rule, or else automating the currying of dependent functions. | ||||
| * | Dependent product rules done and proofs of typing properties so far work. ↵ | Josh Chen | 2018-05-28 | 2 | -64/+110 |

| | | |||||
| * | Decided to go with no explicit type declarations in object-lambda ↵ | Josh Chen | 2018-05-10 | 2 | -25/+43 |
