type t

Type of goals.

val concl : t -> EConstr.constr

concl, hyps, env and sigma given a goal gl return respectively the conclusion of gl, the hypotheses of gl, the environment of gl (i.e. the global environment and the hypotheses) and the current evar map.

val hyps : t -> EConstr.named_context
val env : t -> Environ.env
val sigma : t -> Evd.evar_map
val nf_enter : (t -> unit tactic) -> unit tactic

nf_enter t applies the goal-dependent tactic t in each goal independently, in the manner of tclINDEPENDENT except that the current goal is also given as an argument to t. The goal is normalised with respect to evars.

  • deprecated Normalization is enforced by EConstr, please use [enter]
val enter : (t -> unit tactic) -> unit tactic

Like nf_enter, but does not normalize the goal beforehand.

val enter_one : ?__LOC__:string -> (t -> 'a tactic) -> 'a tactic

Like enter, but assumes exactly one goal under focus, raising a fatal error otherwise.

val goals : t tactic list tactic

Recover the list of current goals under focus, without evar-normalization. FIXME: encapsulate the level in an existential type.

val unsolved : t -> bool tactic

unsolved g is true if g is still unsolved in the current proof state.

val goal : t -> Evar.t

Compatibility: avoid if possible
