gmsv_workshop

This module allows for servers to use the steamworks.DownloadUGC and steamworks.FileInfo functions, enabling runtime downloading & mounting of Workshop addons and GMA files through game.MountGMA

No additional configuration is needed, just install the module to the server and scripts can make use of it.

Installation

First, run this command in your server console to determine the correct module to download:

lua_run print("gmsv_workshop_" .. ((system.IsLinux() and "linux" .. (jit.arch == "x86" and "" or "64")) or (system.IsWindows() and "win" .. (jit.arch == "x86" and "32" or "64")) or "UNSUPPORTED") .. ".dll")

Next, download the module from the releases page

Finally, drop the DLL file in garrysmod/lua/bin in your server files. If the lua/bin folder doesn't exist, create it.

"Couldn't load module library!" error or similar

Either:

1. Your server is outdated
2. (Most likely) Your server is running the x86-64 branch in 32-bit. If you start your x86-64 branch server using the srcds_run binary, this is the problem. Start it using srcds_run_x64 to launch it in 64-bit.
3. Garry's Mod updated the Steamworks version and this now needs to be recompiled against it, open an issue if this is the case.
