FILTER_ONCE_ASM_REWRITE_TAC

Rewrite.FILTER_ONCE_ASM_REWRITE_TAC : ((term -> bool) -> thm list -> tactic)

Rewrites a goal once including built-in rewrites and some of its assumptions.

The first argument is a predicate applied to the assumptions. The goal is rewritten with the assumptions for which the predicate returns true, the given list of theorems, and the tautologies stored in implicit_rewrites. It searches the term of the goal once, without applying rewrites recursively. Thus it avoids the divergence which can result from the application of FILTER_ASM_REWRITE_TAC. For more information on rewriting tactics, see GEN_REWRITE_TAC.

Failure

Never fails.

This function is useful when rewriting with a subset of assumptions of a goal, allowing control of the number of rewriting passes.
