Add comma separated multi labels facility

[rgee0]

Signed-off-by: Richard Gee richard@technologee.co.uk

Description

This change enables multiple labels to be applied through a single comment, by allowing for a comma separated list to be provided. Also added plural aliases for the labels commands.

As the deletion of multiple labels is currently an iterative process, due to how the GitHub API is presented, an error could occur mid-flow when deleting and cause subsequent labels to not be applied. Mitigation against this is that labels are visually verifiable.

Motivation and Context

Currently to add multiple labels a maintainer must add one comment for each label. Members have found this confusing with some calling the command multiple times per comment.

[x] I have raised an issue to propose this change (fixes #32, closes #110 )

How Has This Been Tested?

Unit tests added. Built Derek at rgee0/derek:multiLabels Deployed locally Tested on test repo - https://github.com/rgee0/Test/issues/7

What's the limit in one command?

[alexellis]

I guess this is what I'd be concerned about - intentional or otherwise:

• Spam
• Abuse
• Exhausting rate limit

[alexellis]

What if we set a limit to something like 5 labels at once and have that configurable?

Other than my comment here I think this is ready to merge. What do you think Richard?

What if we set a limit to something like 5 labels at once and have that configurable?

And the action upon finding more?

[alexellis]

Set a reasonable value, then ignore anything over.
