Leonardo de Moura	c2ab31113f	refactor(library/tactic): remove cex_builder and 'precision' for proof_state's These two features make sense for solvers, but not in a general purpose tactic framework for building proofs like the one in Lean. In most cases, we cannot build a counterexample anyway. These two features should be added in a custom framework for combining preprocessing techniques like in Z3.

Leonardo de Moura	ad7b13104f	feat(*): add support for heterogeneous equality in the parser, elaborator and simplifier, adjusts unit test to reflect changes Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2014-02-07 15:03:16 -08:00
Leonardo de Moura	6d7ec9d7b6	refactor(kernel): add heterogeneous equality back to expr The main motivation is that we will be able to move equalities between universes. For example, suppose we have A : (Type i) B : (Type i) H : @eq (Type j) A B where j > i We didn't find any trick for deducing (@eq (Type i) A B) from H. Before this commit, heterogeneous equality as a constant with type heq : {A B : (Type U)} : A -> B -> Bool So, from H, we would only be able to deduce (@heq (Type j) (Type j) A B) Not being able to move the equality back to a smaller universe is problematic in several cases. I list some instances in the end of the commit message. With this commit, Heterogeneous equality is a special kind of expression. It is not a constant anymore. From H, we can deduce H1 : A == B That is, we are essentially "erasing" the universes when we move to heterogeneous equality. Now, since A and B have (Type i), we can deduce (@eq (Type i) A B) from H1. The proof term is (to_eq (Type i) A B (to_heq (Type j) A B H)) : (@eq (Type i) A B) So, it remains to explain why we need this feature. For example, suppose we want to state the Pi extensionality axiom. axiom hpiext {A A' : (Type U)} {B : A → (Type U)} {B' : A' → (Type U)} : A = A' → (∀ x x', x == x' → B x == B' x') → (∀ x, B x) == (∀ x, B' x) This axiom produces an "inflated" equality at (Type U) when we treat heterogeneous equality as a constant. The conclusion (∀ x, B x) == (∀ x, B' x) is syntax sugar for (@heq (Type U) (Type U) (∀ x : A, B x) (∀ x : A', B' x)) Even if A, A', B, B' live in a much smaller universe. As I described above, it doesn't seem to be a way to move this equality back to a smaller universe. So, if we wanted to keep the heterogeneous equality as a constant, it seems we would have to support axiom schemas. That is, hpiext would be parametrized by the universes where A, A', B and B'. Another possibility would be to have universe polymorphism like Agda. None of the solutions seem attractive. So, we decided to have heterogeneous equality as a special kind of expression. And use the trick above to move equalities back to the right universe. BTW, the parser is not creating the new heterogeneous equalities yet. Moreover, kernel.lean still contains a constant name heq2 that is the heterogeneous equality as a constant. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2014-02-07 10:28:10 -08:00
Leonardo de Moura	d4b08fcf96	feat(library/elaborator): be 'lazy' when normalizing terms in the elaborator Unification constraints of the form ctx \|- ?m[inst:i v] == T and ctx \|- (?m a1 ... an) == T are delayed by elaborator because the produce case-splits. On the other hand, the step that puts terms is head-normal form is eagerly applied. This is a bad idea for constraints like the two above. The elaborator will put T in head normal form before executing process_meta_app and process_meta_inst. This is just wasted work, and creates fully unfolded terms for solvers and provers. The new test demonstrates the problem. In this test, we mark several terms as non-opaque. Without this commit, the produced goal is a huge term.

Leonardo de Moura	e3dc552c39	fix(library/simplifier): nontermination The example tests/lua/simp1.lua demonstrates the issue. The higher-order matcher matches closed terms that are definitionally equal. So, given a definition definition a := 1 it will match 'a' with '1' since they are definitionally equal. Then, if we have a theorem theorem a_eq_1 : a = 1 as a rewrite rule, it was triggering the following infinite loop when simplifying the expression "a" a --> 1 --> 1 --> 1 ... The first simplification is expected. The other ones are not. The problem is that "1" is definitionally equal to "a", and they match. The rewrite_rule_set manager accepts the rule a --> 1 since the left-hand-side does not occur in the right-hand-side. To avoid this loop, we test if the new expression is not equal to the previous one. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2014-01-31 15:55:21 -08:00

Leonardo de Moura	29e448f034	fix(library/simplifier): remove support in the simplifier for (forall x : A, B x) when it is not a proposition, the problem is that hpiext axiom produces an equality in a too big universe For example, in the hpiext axiom, the resultant equality if for (Type M+1) axiom hpiext {A A' : TypeM} {B : A -> TypeM} {B' : A' -> TypeM} : A = A' -> (∀ x x', x == x' -> B x = B' x') -> (∀ x, B x) = (∀ x, B' x) even if the actual arguments A, A’, B, B’ "live" in a much smaller universe (e.g., Type). So, it would be great if we could move the resultant equality back to the right universe. I don't see how to do it right now. The other solution would require a major rewrite of the code base. We would have to support universe level arguments like Agda, and write the axiom hpiext as: axiom hpiext {l : level} {A A' : (Type l)} {B : A -> (Type l)} {B' : A' -> (Type l)} : A = A' -> (∀ x x', x == x' -> B x = B' x') -> (∀ x, B x) = (∀ x, B' x) This is the first instance I found where it is really handy to have this feature. I think this would be a super clean solution, but it would require a big rewrite in the code base. Another problem is that the actual semantics that Agda has for this kind of construction is not clear to me. For instance, sometimes Agda reports that the type of an expression is (Set omega). An easier to implement hack is to support "axiom templates". We create instances of hipext "on-demand" for different universe levels. This is essentially what Coq does, since the universe levels are implicit in Coq. This is not as clean as the Agda approach, but it is much easier to implement. A super dirty trick is to include some instances of hpiext for commonly used universes (e.g., Type and (Type 1)). Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2014-01-26 12:10:34 -08:00

Leonardo de Moura	8214c7add4	feat(library/elaborator): compensate the lack of eta-reduction (and eta-expanded normal forms) in the kernel normalizer Before this commit, the elaborator was solving constraints of the form ctx \|- (?m x) == (f x) as ?m <- (fun x : A, f x) where A is the domain of f. In our kernel, the terms f and (fun x, f x) are not definitionally equal. So, the solution above is not the only one. Another possible solution is ?m <- f Depending of the circumstances we want ?m <- (fun x : A, f x) OR ?m <- f. For example, when Lean is elaborating the eta-theorem in kernel.lean, the first solution should be used: ?m <- (fun x : A, f x) When we are elaborating the axiom_of_choice theorem, we need to use the second one: ?m <- f Of course, we can always provide the parameters explicitly and bypass the elaborator. However, this goes against the idea that the elaborator can do mechanical steps for us. This commit addresses this issue by creating a case-split ?m <- (fun x : A, f x) OR ?m <- f Another solution is to implement eta-expanded normal forms in the Kernel. With this change, we were able to cleanup the following "hacks" in kernel.lean: @eps_ax A (nonempty_ex_intro H) P w Hw @axiom_of_choice A B P H where we had to explicitly provided the implicit arguments This commit also improves the imitation step for Pi-terms that are actually arrows.

Leonardo de Moura	9eb4dc4a81	feat(kernel, library/elaborator, frontends/lean): improve how elaborator_exceptions are displayed in the Lean frontend This commit affects different modules. I used the following approach: 1- I store the metavariable environment at unification_failure_justifications. The idea is to capture the set of instantiated metavariables at the time of failure. 2- I added a remove_detail function. It removes propagation steps from the justification tree object. I also remove the backtracking search space associated with higher-order unificiation. I keep only the search related to case-splits due to coercions and overloads. 3- I use the metavariable environment captured at step 1 when pretty printing the justification of an elaborator_exception.

Leonardo de Moura	9620b00e24	feat(kernel/metavar): is instantiate_metavars, we are also instantiating assigned metavariables that occur in the local context of unassinged ones. This modification improves the effectiveness of the process_metavar_inst procedure in the Lean elaborator. For example, suppose we have the constraint ctx \|- ?M1[inst:0 ?M2] == a If ?M1 and ?M2 are unassigned, then we have to consider the two possible solutions: ?M1 == a or ?M1 == #0 and ?M2 == a On the other hand, if ?M2 is assigned to b, then we can ignore the second case.
