Hi Zhao, Lmod always executes modulefiles inside a restricted sandbox; there is no setting to allow full Lua execution directly in a modulefile. To run unrestricted Lua, place your logic in SitePackage.lua (which is not sandboxed) and expose selected functions to modulefiles via sandbox_registration. This is the supported way to grant modulefiles controlled access to full Lua. Modifying src/sandbox.lua to loosen restrictions is possible but unsafe and not recommended. For details, see the “SitePackage.lua and the Sandbox” section of the Lmod documentation. If you share what functionality you need, I can suggest the safest approach.

Dear Robert and the Lmod community, It appears that Lmod runs modulefiles within a restricted sandbox environment, limiting access to the full standard Lua library (e.g., certain `os.*` or `io.*` functions). Is there a configuration option or a specific method to allow the execution of **arbitrary/full Lua code** directly within a `.lua` modulefile? Best regards, Zhao -- Assoc.
