missing subdir_glob implementation?

[cartazio]

I've been trying out using buck2 on some C++, and i've noticed that while theres references to subdir_glob, it isn't implmented. I'm not sure if that is expressible in starlark or needs to be a primitive in buck2 itself though

[cjhopman]

It can be expressed in starlark. Here's an implementation I found: https://github.com/LoopPerfect/rxterm/blob/master/subdir_glob.bzl. It looks basically the same as our internal one, maybe that's actually available already too.

[ndmitchell]

We seem to recommend this as the standard pattern with things like android_resource. Should we move subdir_glob into the prelude and perhaps even make it available alongside glob by default?

[ndmitchell]

Moving this to the buck2 repo where we are aiming to keep all our issues together.

[cartazio]

asking again since i'm looking at this project i want to do again, and i'm fuzzy on how to do this still

[ndmitchell]

Where are you hoping to use subdir_glob? Is https://github.com/LoopPerfect/rxterm/blob/master/subdir_glob.bzl sufficient?

[cartazio]

so the problem i'm hitting is, to use buck2 testing functionality with C++, i have to include GTest! Is there some documented mechanism for doing this thats not on the main documentation site?
