Re: Tips to add optional arguments on dnf using plugin

Hi Marek,

First, Thanks very much for you reply...

I need to add a "global" argument so I can change the layer of a repository... For example:

$ dnf repolist --set-layer=mylayer
$ dnf install -y any_repo --set-layer=mylayer 

So on my plug-in I can change layer in repository to do anything, for that running process, to a different layer. (For example)..

That's the reason I need a "global" argument, not a command, so I can use these arg on any dnf command, like "-v" argument..

I saw your email related to reposync, but reposync use a command, so I need to add a command "reposync" and its arguments... As I explain above, I need a global argument to work with all dnf commands...

That's my real problem, I do not know if dnf plug-in give me access to do that... 

On yum, I made these using init_hook() def, and setting the args.. But dnf doesn't no have init_hook anymore.... 

Again, thanks for your time and help, any tips will be welcome..

Cheers!

Each DNF command could have static method set_argparser (here is the
example from reposync plugin:
https://github.com/rpm-software-management/dnf-plugins-core/blob/master/plugins/reposync.py#L60)
which can be used for adding command specific arguments. However there
is no such method for adding global arguments.
May I ask you to elaborate your use case in more details? What are you
trying to achieve?

Regards,

Marek
