jrr6	b4b878b2d0	fix: prevent `exact?` and `apply?` from suggesting invalid tactics (#7192 ) This PR prevents `exact?` and `apply?` from suggesting tactics that correspond to correct proofs but do not elaborate, and it allows these tactics to suggest `expose_names` when needed. These tactics now indicate that a non-compiling term was generated but do not suggest that that term be inserted. `exact?` also no longer suggests that the user try `apply?` if no partial suggestions were found. This addresses part of #5407 but does not achieve the exact expected behavior therein (due to #6122).	2025-02-25 15:24:09 +00:00

Leonardo de Moura	b81dd3e7ad	feat: `expose_names` tactic (#6935 ) This PR adds the tactic `expose_names`. It creates a new goal whose local context has been "exposed" so that every local declaration has a clear, accessible name.

fix: prevent exact? and apply? from suggesting invalid tactics (#7192 )

This PR prevents `exact?` and `apply?` from suggesting tactics that
correspond to correct proofs but do not elaborate, and it allows these
tactics to suggest `expose_names` when needed.

These tactics now indicate that a non-compiling term was generated but
do not suggest that that term be inserted. `exact?` also no longer
suggests that the user try `apply?` if no partial suggestions were
found.

This addresses part of #5407 but does not achieve the exact expected
behavior therein (due to #6122).

feat: expose_names tactic (#6935 )

This PR adds the tactic `expose_names`. It creates a new goal whose
local context has been "exposed" so that every local declaration has a
clear, accessible name. If no local declarations require renaming, the
original goal is returned unchanged.

This tactic will be used to improve `try?`.
