channels priority logic question

[trim21]

I failed to understand the logic of channel priority here: https://pixi.sh/latest/advanced/channel_priority/

If a feature has channels ['a','b', {channel='c', priority=1}, {channel='d', priority=-1}] and default channels is ['conda-forge', 'cuda']

we will prepend then channels of this feature to the default channels then sort then?

like this: first merge them to ['a','b', {channel='c', priority=1}, {channel='d', priority=-1}, 'conda-forge', 'cuda'], then sort it to ['c', 'a','b', 'conda-forge', 'cuda', 'd'] ?

Yes, all channels have priority 0, unless specified differently. If you specify [a, b] they both have priority 0 but a is first in the list of priority 0. If you then add a feature to the list with [c] this gets put in front of a as the addition makes it the more important position.

Running pixi info will show you the order of importance of these channels if you test it locally.
