Proofs and tactics.

goal_meta : Core.Term.meta;
(*Goal metavariable.
*)goal_hyps : Core.Env.t;
(*Precomputed scoping environment.
*)goal_type : Core.Term.term;
(*Precomputed type.

}
Type of goals.
add_goals_of_problem p gs
extends the list of goals gs
with the metavariables and constraints of p
.
type proof_state = {
proof_name : Common.Pos.strloc;
(*Name of the theorem.
*)proof_term : Core.Term.meta option;
(*Optional metavariable holding the goal associated to a symbol used as a theorem/definition and not just a simple declaration
*)proof_goals : goal list;
(*Open goals (focused goal is first).
*)
}
Representation of the proof state of a theorem.
finished ps
tells whether there are unsolved goals in ps
.
goals ppf gl
prints the goal list gl
to channel ppf
.
remove_solved_goals ps
removes from the proof state ps
the typing goals that are solved.
meta_of_key ps i
returns Some m
where m
is a meta of ps
whose key is i
, or else it returns None
.
focus_env ps
returns the scoping environment of the focused goal or the empty environment if there is none.
