Hi,

langpacks-<langcode> packages aren't necessarily installed for a primary locale. So I don't think such rich deps works as expected, particularly to figure out the regions for users. Plus, we have font packages installed by default to cover the majority of languages for convenience. So requiring font packages conditionally may not work too.

BTW is there any reason that the package requires a non variable font package? If it works with the variable font, I think you can simply drop its dependency since we have google-noto-sans-cjk-vf-fonts installed by default as well as google-noto-sans-vf-fonts. Otherwise it may be better to fix it.

Hello,

a package I co-mainatin bundles google-noto-sans-fonts and google-noto-sans-cjk-fonts upstream.

The fonts are removed from the package. We want to add a dependency on them, like this:

Requires: google-noto-sans-fonts Requires: google-noto-sans-cjk-fonts

However, it was pointed out in [1] that the cjk fonts are quire large and probably no use for non-APAC users. (CJK is the shorthand collective name for the Chinese, Japanese, and Korean writing systems.)

We could do:

Requires: google-noto-sans-fonts Recommends: google-noto-sans-cjk-fonts

But that still installs it to everybody by default.

I was wondering if there is a rich dep magic I could use.

E.g.

Requires: google-noto-sans-fonts Requires: (google-noto-sans-cjk-fonts if langpacks-fonts-...)

However, there seem to be no general langpack for cjk.

I could try to reverse engineering all the langpacks that need cjk fonts from, the code [2], but perhaps there is a more general way?

I see that langpacks-fonts-ja/ko/zh_* Requires google-noto-sans-mono-cjk-vf-fonts and google-noto-serif-cjk-vf-fonts. So I can do:

Requires: (google-noto-sans-cjk-fonts if google-noto-serif-cjk-vf-fonts)

But can I assume this will always be the case?
