From 658906e9ea6fa73e341d853406ccd9025873f4ae Mon Sep 17 00:00:00 2001 From: Daniel Gibbs Date: Sun, 19 Apr 2026 01:05:31 +0100 Subject: [PATCH] feat(etl): add downloader and update support for ET: Legacy Refactors ET: Legacy to use a dedicated update module instead of hardcoded installation files. The new update_etl.sh module leverages the GitHub API to check for, download, and apply the latest builds from GameServerManagers/etlserver-build. --- lgsm/modules/command_check_update.sh | 2 + lgsm/modules/command_update.sh | 2 + lgsm/modules/install_server_files.sh | 10 +- lgsm/modules/update_etl.sh | 167 +++++++++++++++++++++++++++ 4 files changed, 173 insertions(+), 8 deletions(-) create mode 100644 lgsm/modules/update_etl.sh diff --git a/lgsm/modules/command_check_update.sh b/lgsm/modules/command_check_update.sh index 38f8b4ddc..6e429512a 100755 --- a/lgsm/modules/command_check_update.sh +++ b/lgsm/modules/command_check_update.sh @@ -34,6 +34,8 @@ elif [ "${shortname}" == "ut99" ];
