.yaml, .rul?

[robin]

So as far as I understand OXC ".rul" files are/contain YAML.

What is the difference between a ".yml/.yaml" yaml file and a ".rul" yaml file?

This is what I find if I search for .rul files:

A .rul file is a text file containing InstallScript code (just as a .cpp file typically contains C++ code, and so forth). InstallScript projects typically have a source file with the special name setup.rul. For information about the InstallScript language, please see the InstallScript Language Reference section of the InstallShield help.

Does it refers to files  with the same (.rul) extension but different language than OXC's ".rul" ones? Or are they the very same files (AKA yaml file than contains InstaScript code)?

Thanks

it's yaml.
the filename extension is meaningless.

We could name any extension. There is no any convention about that. It could be even without any. It just matter of usability and not falling into too apparent ambiguity. Extension is not always relevant to contents. Treat it as it is, Robin.
