Use properties in isVisible hook

[wpoely86]

I'm looking if we can use properties of a module in the isVisible hook. The specific use case would be to 'hide' modules with the gpu property on non-gpu nodes.

As far as I figure out, it's not possible today as the hook only gets a table with:

• fullName
• sn (short name)
• fn (file path)

The properties are part of the module itself. It's not clear to me if we could get access to this kind of information in the hook?

I have modified Lmod 8.6.2 to add mname and mt objects to the table that is passed to the isVisible Hook routine.

You can use function mt:haveProperty(sn, propName, propValue) to check for arch gpu. For example:

   local haveGpu = mt:haveProperty(sn,"arch","gpu")

Thanks Robert. I will give it a spin!

It could be a nice topic for a future Lmod monthly talk on how exactly you got this done cause I'm not sure I fully understand it ;)

O.K. to close this issue?
