| 2021-01-18 | Swapped notation for metas (now ?) and holes (now {}), other notation and ↵ | Josh Chen | 4 | -69/+76 | |
| name changes. | |||||
| 2020-09-23 | Basic experiments adding reduction to the type checker | Josh Chen | 3 | -73/+26 | |
| 2020-08-14 | (FEAT) Context data slots for known types and conditional type rules, as ↵ | Josh Chen | 3 | -48/+47 | |
| well as a separate one for judgmental equality rules. (REF) Goal statement assumptions are now put into the new context data slots. (FEAT) `assuming` Isar keyword—like `assume` but puts assumptions into context data. (REF) Typechecking and all other tactics refactored to use type information from the context data, as opposed to looking at all facts visible in context. MINOR INCOMPATIBILITY: facts that were implicitly used in proofs now have to be annotated with [type] to make them visible throughout the context, else explicitly passed to methods via `using`, or declared with `assuming`. (REF) Fixed incompatibilities in theories. | |||||
| 2020-08-09 | (FEAT) Clean up typechecking/elaboration tactic: known_ctac should *solve* ↵ | Josh Chen | 1 | -7/+6 | |
| goals; resolving with conditional typing judgments (e.g. type family assumptions) is part of check_infer_step | |||||

| normalization in typechecking/elaboration. | |||||
| 2020-08-03 | (FEAT) SIDE_CONDS tactical has additional argument specifying how many ↵ | Josh Chen | 2 | -15/+7 | |
| initial subgoals to skip applying the side condition solver to. (FEAT) `intro`, `intros` methods for "logical introduction rules" (as opposed to typechecking `intr` attribute), only works on conclusions with rigid type. (FEAT) CREPEAT_N bounded repetition tactical, used in `intros n` method. | |||||

| . spartan/core/goals.ML . spartan/core/elaboration.ML . spartan/core/elaborated_statement.ML (FEAT) More context tacticals and search tacticals. . spartan/core/context_tactical.ML (FEAT) Improved subgoal focus. Moves fully elaborated assumptions into the context (MINOR INCOMPATIBILITY). . spartan/core/focus.ML (FIX) Normalize facts in order to be able to resolve properly. . spartan/core/typechecking.ML (MAIN) New definitions. (MAIN) Renamed theories and theorems. (MAIN) Refactor theories to fit new features. | |||||

| 2020-07-21 | 1. Bugfix: implicits now properly name schematic variables. Fixes problems ↵ | Josh Chen | 2 | -19/+22 | |
| caused by variable name clashes. 2. reduce method now more principled: restricts to repeating on first subgoal. 3. An example declarative proof in Equivalence.thy. | |||||
| 2020-07-21 | 1. Type-checking/inference now more principled, and the implementation is ↵ | Josh Chen | 5 | -117/+109 | |
| better. 2. Changed most tactics to context tactics. | |||||
