From 24e3bfa168250a99d5543b7c6604af9f11a4d2b6 Mon Sep 17 00:00:00 2001 From: Florian Fischer Date: Mon, 30 Dec 2024 08:55:49 +0100 Subject: lazily initialize the default logger In order for the user to configure the logging behavior the values of lspc.logging and lspc.log_file must be evaluated after vis-lspc was required. To lazily evaluate the logging configuration a new LazyInitLogger metatable is introduced, which initializes the actual logger on first use.
