Re: Tips to add optional arguments on dnf using plugin

[Fellipe Henrique <fellipeh@xxxxxxxxx>]

Thinking here about these...

If I made a fork from dnf package, and put arguments inside OptionParser class, on option_parser.py... I get the "global" argument as I needed... but how can I get these argument value inside my plugin?  Any idea?

cheers

So,

Using dnf plugin, I can't do that, if I understand correctly...  As I said  on my last email, I have these coded using yum, like these:

def init_hook(pc):
   '''Initial Hook that configures the repositories'''
   parser = pc.getOptParser()
   if parser:
      parser.add_option('', '--set-repository-layer',
              dest='set_repository_layer',
              action="" nargs=1)

But, I can't do these using a new plugin approach on dnf, only if I use command... but command doesn't work with all dnf commands( repolist, install, remove etc..)

Maybe I need to change my approach, as you said @Nicolas

Cheers!

On our setup we approximate this via <layer>-repo naming

So dnf commands become dnf --disablerepo * --enablerepo <layer>-*

Tried to play with passing yum/dnf explicit config paths, that didn’t
work out so well. (I’ve seen others try to switch personalities via YUMx
variables, the result is also quite user unfriendly).

Of course that’s some pretty big hammer and that disables the ability to
preset repos to on or off within a layer. It would be much nicer if
there was a way to define things as part of a configuration set in
/etc/yum*, and enable/disable specific configuration sets on the cli.

One use case is reposync, since one typically wants the system to use
the remote repos once synced, so every repo has one personality for
reposync, and another for the system dnf itself.
