It also now generates a preset file importable through the Arma Launcher.
You can also host this file on a webserver, and import it by pasting the link in the "File Name" field.

Fixed an issue if keys aren't found
👌
Hey, it would be awesome if this also generated a startup script, which would load mods according to this config

@Buri For that I'd recommend you check out https://github.com/Dahlgren/arma-server-web-admin
The rename step was failing for me for some reason. But I re-implemented it in Python and it worked fine, which I think makes more sense anyways.
def lowercase_workshop_dir():
def rename_all(root, items):
for name in items:
try:
os.rename(os.path.join(root, name), os.path.join(root, name.lower()))
except OSError:
pass
for root, dirs, files in os.walk(A3_WORKSHOP_DIR, topdown=False):
rename_all(root, dirs)
rename_all(root, files)Also, something that was useful to me was generate the -mod parameter and printing them at the end (although can easily be extending to add the -servermod param too".
def print_launch_params():
rel_path = os.path.relpath(A3_MODS_DIR, A3_SERVER_DIR)
params = "-mod"
for mod_name, mod_id in MODS.items():
params += "{}/{}\;".format(rel_path, mod_name)
print(params)
there has been some changes to steamCMD.
now this script throws an error Please use force_install_dir before logon!
to fix this simply swap places for " +force_install_dir {}".format(A3_SERVER_DIR)and " +login {} {}".format(STEAM_USER, STEAM_PASS)
so it ends up looking like:
def update_server():
steam_cmd_params = " +force_install_dir {}".format(A3_SERVER_DIR)
steam_cmd_params += " +login {} {}".format(STEAM_USER, STEAM_PASS)
steam_cmd_params += " +app_update {} validate".format(A3_SERVER_ID)
steam_cmd_params += " +quit"
...
def update_mods():
....
steam_cmd_params = " +force_install_dir {}".format(A3_SERVER_DIR)
steam_cmd_params += " +login {} {}".format(STEAM_USER, STEAM_PASS)
steam_cmd_params += " +workshop_download_item {} {} validate".format(a small discussion where I learned about this:
ValveSoftware/steam-for-linux#8298
ps. downloading workshop items(missions) works only if the steam account owns the game!
