Proposal: snapcraftctl set-source

snapcraft

Sometimes the actual source url must be determined at build time (e.g. The latest tarball from an apache file listing page parsed in override-pull), it would be great if Snapcraft supports setting the source property using snapcraftctl so that we can directly snapcraftctl pull after setting the proper source url.

parts:
  links:
    # source: determined-in-override-pull
    override-pull: |
      latest_release="$(
        wget \
          --output-document=- \
          http://links.twibright.com/download \
          2>/dev/null \
          | grep \
            --only-matching \
            --extended-regexp \
            'href="links-.*.tar.bz2"' \
          | cut --delimiter='"' --fields=2 \
          | sort --version-sort --reverse \
          | head --lines=1 \
          | cut --characters=7- \
          | sed 's/.tar.bz2//'
      )"
      snapcraftctl set-version \
        "$latest_release"
      snapcraftctl set-source \
        "http://links.twibright.com/download/links-$latest_release.tar.bz2"
      snapcraftctl pull
