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	e8bba1ebf3	fix(frontends/lean/frontend): the definition of the explicit version @f must be definitionally equal to f Before this commit, the explicit version @f of a constant f with implicit arguments as not definitionally equal to f. For example, if we had variable f {A : Type} : A -> Bool Then, the definition of @f was definition @f (A : Type) (a : A) : Bool := f A a This definition is equivalent to fun A a, f A a which is not definitionally equal to f since definitionally equality in Lean ignores Eta conversion.

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.

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.

Leonardo de Moura	7772c16033	refactor(kernel): add unfold_opaque flag to normalizer, modify how type checker uses the opaque flag, remove hidden_defs, and mark most builtin definitions as opaque After this commit, in the type checker, when checking convertability, we first compute a normal form without expanding opaque terms. If the terms are convertible, then we are done, and saved a lot of time by not expanding unnecessary definitions. If they are not, instead of throwing an error, we try again expanding the opaque terms. This seems to be the best of both worlds. The opaque flag is a hint for the type checker, but it would never prevent us from type checking a valid term. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-12-20 12:47:47 -08:00

Leonardo de Moura	812c1a2960	feat(library/elaborator): only expand definitions that are not marked as hidden The elaborator produces better proof terms. This is particularly important when we have to prove the remaining holes using tactics. For example, in one of the tests, the elaborator was producing the sub-expression (λ x : N, if ((λ x::1 : N, if (P a x x::1) ⊥ ⊤) == (λ x : N, ⊤)) ⊥ ⊤) After, this commit it produces (λ x : N, ¬ ∀ x::1 : N, ¬ P a x x::1) The expressions above are definitionally equal, but the second is easier to work with. Question: do we really need hidden definitions? Perhaps, we can use only the opaque flag. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-12-20 02:16:49 -08:00

It also fixes process_meta_app in the elaborator. The problem was in the method process_meta_app and process_meta_inst. They were processing convertability constrains as equality constraints. For example, process_meta_app would handle ctx \|- Type << ?f b as ctx \|- Type =:= ?f b This is not correct because a ?f that returns (Type U) for b satisfies the first but not the second.

Leonardo de Moura	f97c260b0b	refactor(kernel/environment): add ro_environment The environment object is a "smart-pointer". Before this commit, the use of "const &" for environment objects was broken. For example, suppose we have a function f that should not modify the input environment. Before this commit, its signature would be void f(environment const & env) This is broken, f's implementation can easilty convert it to a read-write pointer by using the copy constructor. environment rw_env(env); Now, f can use rw_env to update env. To fix this issue, we now have ro_environment. It is a shared const pointer. We can convert an environment into a ro_environment, but not the other way around. ro_environment can also be seen as a form of documentation. For example, now it is clear that type_inferer is not updating the environment, since its constructor takes a ro_environment.
