From 2ef39fb79e13f66b0eef03be0b3a9efb5dda9bad Mon Sep 17 00:00:00 2001 From: "copilot-swe-agent[bot]" <198982749+Copilot@users.noreply.github.com> Date: Mon, 15 Dec 2025 16:06:16 +0000 Subject: [PATCH] Add optional start/end parameters to tp-forward-do and tp-backward-do The function parameter now supports optional second and third arguments: - (function text) - backward compatible with existing code - (function text start) - receives match start position - (function text start end) - receives both start and end positions This uses func-arity to detect how many arguments the function accepts and passes the appropriate parameters.
