How to list dependencies in pyang #741

Open bipinb1994 opened 3 years ago

bipinb1994 commented 3 years ago

Does pyang provide a way to list down the dependent yang models that should be installed before it's getting installed? Or any such info? Dependency tree kind of something?

Hi, no, there's no such a way to provide the dependency tree.

I'd like to know what's your usage scenario. As much as I know, all the dependency for a YANG model is that the import statements.

When use pyang to check a YANG model file, it will check all the dependency models. If it is not installed or cannot find in the path, the error is throwed.

Hi, Is it possible to merge the yang files if it has import statement . Like I have to merge the file and it's dependent file.

This dependency information should all be present in pyang's internal structures.

Perhaps it would be useful to look at the source code for the depend format? Perhaps take a look at the add_prereqs() function and see whether you can adjust it to do what you want.
