The tacticals in the module New are the tactical of Ltac. Their semantics is an extension of the tacticals in this file for the multi-goal backtracking tactics. They do not have the same semantics as the similarly named tacticals in Proofview. The tactical of Proofview are used in the definition of the tacticals of Tacticals.New, but they are more atomic. In particular Tacticals.New.tclORELSE sees lack of progress as a failure, whereas Proofview.tclORELSE doesn't. Additionally every tactic which can catch failure (tclOR, tclORELSE, tclTRY, tclREPEAt, etc…) are run into each goal independently (failures and backtracks are localised to a given goal).

val catch_failerror : Exninfo.iexn -> unit Proofview.tactic

catch_failerror e fails and decreases the level if e is an Ltac error with level more than 0. Otherwise succeeds.

val tclIDTAC : unit Proofview.tactic
val tclTHEN : unit Proofview.tactic -> unit Proofview.tactic -> unit Proofview.tactic
val tclFAIL : ?info:Exninfo.info -> int -> Pp.t -> 'a Proofview.tactic
val tclZEROMSG : ?info:Exninfo.info -> ?loc:Loc.t -> Pp.t -> 'a Proofview.tactic

Fail with a User_Error containing the given message.

val tclOR : unit Proofview.tactic -> unit Proofview.tactic -> unit Proofview.tactic
val tclORD : unit Proofview.tactic -> (unit -> unit Proofview.tactic) -> unit Proofview.tactic

Like tclOR but accepts a delayed tactic as a second argument in the form of a function which will be run only in case of backtracking.

tclTHENS3PARTS tac1 [|t1 ; ... ; tn|] tac2 [|t'1 ; ... ; t'm|] gls applies the tactic tac1 to gls then, applies t1, ..., tn to the first n resulting subgoals, t'1, ..., t'm to the last m subgoals and tac2 to the rest of the subgoals in the middle. Raises an error if the number of resulting subgoals is strictly less than n+m

val tclTHENFIRST : unit Proofview.tactic -> unit Proofview.tactic -> unit Proofview.tactic

tclTHENFIRST tac1 tac2 gls applies the tactic tac1 to gls and tac2 to the first resulting subgoal
