Feature request: filtration by GitHub repo label

[jesdavpet]

Why?

My TELUS is in the process of getting Colophon set up for all of our tribe's GitHub repos (see: https://github.com/telus/my-telus/issues/53). Our motivation is to leverage Colophon to query all of our project repos to audit technical health.

Being able to query all of our repos using Colophon which would provide a lot of value for us, since this has typically been done using "hand crafted" spreadsheets, which is not really a scalable practice.

What?

To accomplish this kind of auditing task, we would like to be able to filter the GitHub repos displayed in the Colophon UI by labels. Currently, the Colophon UI only allows querying by repository name, which is a low value query for auditing across multiple repos.

An example query I would like to run might be something like:

"Find all my-telus repos, created by the external vendor group l33t-h4x0rz, for ui projects, that are authenticated experiences"

IMO adding each of these properties as Colophon entries would add complexity for non-developers to help in auditing, whereas labels have a very low barrier for entry.

How?

• Colophon scraper / query against GitHub API to be augmented to include labels
• Colophon datastore to be extended to store labels
• Colophon UI to be improved to display labels
• Colophon UI to be improved to allow filtration of all telus organization repos by label
• Colophon UI to be improved to allow filtration of all telus organization repos by combination of multiple labels

A "nice to have" for Colophon generally would be to use a webhook or Actions to update a repo's YAML file when the labels have been changed, or vice-versa.
