How do you exclude files from wiki part used in snapcraft.yaml

Question

I am using snapcraft-desktop-helpers-master to integrate my app into desktop.

I have added "after: [desktop/gtk2]" to app part, but how do i exclude files from this imported part to reduce snap file size like for example removed usr/share/doc

Answer 1

This is pretty simple, you can override specific keywords from a remote defined part by redefining the key for the part. This would look something like this:

parts:
    my-part:
        plugin: autotools
        source: .
        after: [desktop/gtk2]
    desktop/gtk2:
        snap:
            - -usr/include

The trick here is that desktop/gtk2 does not define a plugin entry in the parts definition hinting snapcraft to look for the full part definition from the remote parts cache.

Here I used the snap keyword, there are others like stage and filesets

You can override the imported snap options by including them as an entry in your snapcraft.yaml's "parts" section. Parts Ecosystem Blog
