Leonardo de Moura	463e70332d	test(tests/lean/run): define brec_on and binduction_on for a reflexive type We say an inductive type T is reflexive if it contains at least one constructor that takes as an argument a function returning T. For reflexive types it doesn't seen to be possible to define a single brec_on that can eliminate to Type.{>=1} and Prop. The universe level expressions get too complicated. Even if we extend the universe constraint solver in the kernel, the additional complexity might be a problem. We workaround this issue by defining two versions of brec_on: - One (brec_on) that eliminates to Type.{>=1}, and - binduction_on that eliminates to Prop. For non-reflexive types, we can combine both of them.	2014-11-12 10:52:32 -08:00

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

When there is nothing else to be done, try to solve them by reducing to ?m1 = l1 and ?m1 = l2. Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2014-08-02 09:14:35 -07:00

Leonardo de Moura	936bb2744b	fix(library/unifier): add a flag to sign that a choice constraint owns a metavariable ?m, that is, it has the right to assign ?m, and the unifier should postpone any other constraint that tries to assign ?m Signed-off-by: Leonardo de Moura <leonardo@microsoft.com>	2014-07-29 17:32:55 -07:00

Leonardo de Moura	faee08591f	fix(*): make sure elaborator and type_checker use the same "rules" for treating opaque definitions This is a big change because we have to store in constraints whether we can use the "relaxed" rules or not. The "relaxed" case says that when type checking the value of an opaque definition we can treat other opaque definitions in the same module as transparent.
