Leonardo de Moura	b3e05a2fe9	refactor(frontends/lean/scanner): remove dependency to seekg and unget methods It is not safe to use seekg for textual files. Here is a fragment from a C++ manual: seekg() and seekp() This pair of functions serve respectively to change the position of stream pointers get and put. Both functions are overloaded with two different prototypes: seekg ( pos_type position ); seekp ( pos_type position ); Using this prototype the stream pointer is changed to an absolute position from the beginning of the file. The type required is the same as that returned by functions tellg and tellp. seekg ( off_type offset, seekdir direction ); seekp ( off_type offset, seekdir direction ); Using this prototype, an offset from a concrete point determined by parameter direction can be specified. It can be: ios::beg offset specified from the beginning of the stream ios::cur offset specified from the current position of the stream pointer ios::end offset specified from the end of the stream The values of both stream pointers get and put are counted in different ways for text files than for binary files, since in text mode files some modifications to the appearance of some special characters can occur. For that reason it is advisable to use only the first prototype of seekg and seekp with files opened in text mode and always use non-modified values returned by tellg or tellp. With binary files, you can freely use all the implementations for these functions. They should not have any unexpected behavior.	2014-09-18 15:24:48 -07:00

Leonardo de Moura	8df7c7b02d	feat(kernel/type_checker): remove fallback that expands opaque definitions in the type checker We should not rely on this feature. It can be quite expensive. We invoke is_convertible in several places, in particular, if we are using overloading. For example, the frontend uses is_convertible to check which overload should be used. Thus, it will make several calls such as is_convertible(num, Nat) If is_convertible starts unfolding opaque definitions, we would keep expanding num.

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	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.

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
