From ddbb47fde9b6d8cd9f3728847a378f634318cfb1 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ren=C3=A9=20Scharfe?= Date: Sun, 30 Oct 2022 12:55:06 +0100 Subject: replace and remove run_command_v_opt() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Replace the remaining calls of run_command_v_opt() with run_command() calls and explict struct child_process variables. This is more verbose, but not by much overall. The code becomes more flexible, e.g. it's easy to extend to conditionally add a new argument. Then remove the now unused function and its own flag names, simplifying the run-command API.
