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.

Leonardo de Moura	015bff8283	fix(library/tactic/goal): to_goal way of handling context_entries of the form (name, domain, body) where domain is null, and body is a proof term This commit fixes a problem exposed by t13.lean. It has a theorem of the form: Theorem T1 (A B : Bool) : A /\ B -> B /\ A := fun assumption : A /\ B, let lemma1 := (show A by auto), lemma2 := (show B by auto) in (show B /\ A by auto) When to_goal creates a goal for the metavariable associated with (show B /\ A by auto) it receives a context and proposition of the form [ A : Bool, B : Bool, assumption : A /\ B, lemma1 := Conjunct1 assumption, lemma2 := Conjunct2 assumption ] \|- B /\ A The context_entries "lemma1 := Conjunct1 assumption" and "lemma2 := Conjunct2 assumption" do not have a domain (aka type). Before this commit, to_goal would simply replace and references to "lemma1" and "lemma2" in "B /\ A" with their definitions. Note that, "B /\ A" does not contain references to "lemma1" and "lemma2". Then, the following goal is created A : Bool, B : Bool, assumption : A /\ B \|- B /\ A That is, the lemmas are not available when solving B /\ A. Thus, the tactic auto produced the following (weird) proof for T1, where the lemmas are computed but not used. Theorem T1 (A B : Bool) (assumption : A ∧ B) : B ∧ A := let lemma1 := Conjunct1 assumption, lemma2 := Conjunct2 assumption in Conj (Conjunct2 assumption) (Conjunct1 assumption) This commit fixed that. It computes the types of "Conjunct1 assumption" and "Conjunct2 assumption", and creates the goal A : Bool, B : Bool, assumption : A /\ B, lemma1 : A, lemma2 : B \|- B /\ A After this commit, the proof for theorem T1 is Theorem T1 (A B : Bool) (assumption : A ∧ B) : B ∧ A := let lemma1 := Conjunct1 assumption, lemma2 := Conjunct2 assumption in Conj lemma2 lemma1 as expected. Finally, this example suggests that the encoding Theorem T1 (A B : Bool) : A /\ B -> B /\ A := fun assumption : A /\ B, let lemma1 : A := (by auto), lemma2 : B := (by auto) in (show B /\ A by auto) is more efficient than Theorem T1 (A B : Bool) : A /\ B -> B /\ A := fun assumption : A /\ B, let lemma1 := (show A by auto), lemma2 := (show B by auto) in (show B /\ A by auto) Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-12-06 16:14:25 -08:00

Leonardo de Moura	f80106a895	chore(*): use 'explicit operator bool' everywhere. operator bool() may produce unwanted conversions.

Of course, this is not our intention. After this commit, the compiler correctly signs the error. The correct code is ... object const & obj = find_object(const_name(n)); if (obj && obj.is_builtin() && obj.get_name() == const_name(n)) ...

(e'_n, pf_n -- proof of e_n = e'_n). Then rewrite_app function construct the new v' v' = (e'_0 e'_1 ... e'_n) and the proof of v = v' which is constructed with pf_i's. These functions are used in the component rewriters such as app_RW and let_type_RW, as well as more complicated rewriters such as depth rewriter.	2013-11-30 02:25:29 -05:00

Leonardo de Moura	20a36e98ec	feat(library/elaborator): modify how elaborator handles constraints of the form ?M << P and P << ?M, where P is a proposition. Before this commit, the elaborator would only assign ?M <- P, if P was normalized. This is bad since normalization may "destroy" the structure of P. For example, consider the constraint [a : Bool; b : Bool; c : Bool] ⊢ ?M::1 ≺ implies a (implies b (and a b)) Before this, ?M::1 will not be assigned to the "implies-term" because the "implies-term" is not normalized yet. So, the elaborator would continue to process the constraint, and convert it into: [a : Bool; b : Bool; c : Bool] ⊢ ?M::1 ≺ if Bool a (if Bool b (if Bool (if Bool a (if Bool b false true) true) false true) true) true Now, ?M::1 is assigned to the term if Bool a (if Bool b (if Bool (if Bool a (if Bool b false true) true) false true) true) true This is bad, since the original structure was lost.

Leonardo de Moura	d87ad9eb7e	refactor(util/lua): propagate C++ Lean exceptions in Lua The following call sequence is possible: C++ -> Lua -> C++ -> Lua -> C++ The first block of C++ is the Lean main function. The main function invokes the Lua interpreter. The Lua interpreter invokes a C++ Lean API. Then the Lean API invokes a callback implemented in Lua. The Lua callback invokes another Lean API. Now, suppose the Lean API throws an exception. We want the C++ exception to propagate over the mixed C++/Lua call stack. We use the clone/rethrow exception idiom to achieve this goal. Before this commit, the C++ exceptions were converted into strings using the method what(), and then they were propagated over the Lua stack using lua_error. A lua_error was then converted into a lua_exception when going back to C++. This solution was very unsatisfactory, since all C++ exceptions were being converted into a lua_exception, and consequently the structure of the exception was being lost.

Leonardo de Moura	691893258d	feat(kernel/expr): add hash code based on allocation time The new hash code has the property that given expr_cell * c1 and expr_cell * c2, if c1 != c2 then there is a high propbability that c1->hash_alloc() != c2->hash_alloc(). The structural hash code hash() does not have this property because we may have c1 != c2, but c1 and c2 are structurally equal. The new hash code is only compatible with pointer equality. By compatible we mean, if c1 == c2, then c1->hash_alloc() == c2->hash_alloc(). This property is obvious because hash_alloc() does not have side-effects. The test tests/lua/big.lua exposes the problem fixed by this commit. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-11-14 02:43:11 -08:00

Leonardo de Moura	c4c548dc5d	feat(*): simplify interrupt propagation Instead of having m_interrupted flags in several components. We use a thread_local global variable. The new approach is much simpler to get right since there is no risk of "forgetting" to propagate the set_interrupt method to sub-components. The plan is to support set_interrupt methods and m_interrupted flags only in tactic objects. We need to support them in tactics and tacticals because we want to implement combinators/tacticals such as (try_for T M) that fails if tactic T does not finish in M ms. For example, consider the tactic: try-for (T1 ORELSE T2) 5 It tries the tactic (T1 ORELSE T2) for 5ms. Thus, if T1 does not finish after 5ms an interrupt request is sent, and T1 is interrupted. Now, if you do not have a m_interrupted flag marking each tactic, the ORELSE combinator will try T2. The set_interrupt method for ORELSE tactical should turn on the m_interrupted flag.

Leonardo de Moura	9a5f86fce6	feat(lua): use ( ... ) instead of {{ ... }} for nested Lua scripts The token }} is a bad delimiter for blocks of Lua script code nested in Lean files. The problem is that the sequence }} occurs very often in Lua code because Lua uses { and } to build tables/lists/arrays. Here is an example of Lua code that contains the sequence }} t = {{1, 2}, {2, 3}, {3, 4}} In Lean, (* ... ) is used to create comments. Thus, (* ... **) code blocks will not affect valid Lean files. It also looks reasonably good. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-11-12 16:05:49 -08:00

Leonardo de Moura	9c60eed93c	refactor(kernel/metavar): avoid using unique names for default metavariable prefix The problem is that unique names depend on the order compilation units are initialized. The order of initialization is not specified by the C++ standard. Then, different compilers (or even the same compiler) may produce different initialization orders, and consequently the metavariable prefix is going to be different for different builds. This is not a bug, but it makes unit tests to fail since the output produced by different builds is different for the same input file. Avoiding unique name feature in the default metavariable prefix avoids this problem. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-11-07 10:16:25 -08:00

Leonardo de Moura	fd7e85f0bb	feat(lua): add safe_function template that catches Lean and C++ exceptions and convert them into Lua errors I'm using the approach described at: http://stackoverflow.com/questions/4615890/how-to-handle-c-exceptions-when-calling-functions-from-lua BTW, in some Lua versions, the C++ exceptions are correctly propagated. I think we should not rely on features of particular implementations. For example, LuaJIT does not propagate C++ exceptions. Whenever an exception is thrown from C++ code invoked from LuaJit, LuaJit interrupts the execution and converts it to an error "C++ exception". On the other hand, Lua 5.2 PUC-Rio interpreter (for Ubuntu) seem to propagate the C++ exceptions. The template safe_function solves the issue. It will also produce a Lua error whenever the function being wrapped throws an exception. The error message is based on the "what()" method.

Leonardo de Moura	4dd6cead83	refactor(equality): make homogeneous equality the default equality It was not a good idea to use heterogeneous equality as the default equality in Lean. It creates the following problems. - Heterogeneous equality does not propagate constraints in the elaborator. For example, suppose that l has type (List Int), then the expression l = nil will not propagate the type (List Int) to nil. - It is easy to write false. For example, suppose x has type Real, and the user writes x = 0. This is equivalent to false, since 0 has type Nat. The elaborator cannot introduce the coercion since x = 0 is a type correct expression. Homogeneous equality does not suffer from the problems above. We keep heterogeneous equality because it is useful for generating proof terms. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2013-10-29 16:20:06 -07:00
