Query - is branch aware building possible? about auto-ig-builder HOT 6 CLOSED

Thanks Rob! We don't currently build/host branches on IGs, although we have a feature in place to host branches of the main FHIR build (626ca7c).

It would be good to do something similar with IGs. Let me do a quick assessment to determine the level of effort for this -- but I think it should be pretty straightforward.

Thank you very much Josh, that's great.

Reading through your write-up in more detail: making this work from forks is a bit tricker than making it run from separate branches within your main repo. Just to understand the use case: how tied are you to using GH forks?

The key question is where the output will be hosted for review. If we restricted auto-build to branches in the "main" repo, we could have URLs like:

https://build.fhir.org/ig/branches/:org/:repo/:branchname

... but if we auto-build forks, this would break down because multiple forks could use the same branch name, and would be competing for the same space on build.fhir.org.

On the other hand, if we asked fork authors to explicitly, independently set up their forks to auto-build, then we'd have URLs like:

https://build.fhir.org/ig/branches/:orgForForkingUser/:repoForForkingUser/:branchname

... which is more work for contributors, but avoids the ambiguity. Thoughts?

Apologies for the delay in answering Josh. I am not altogether sure I have fully grasped the nuances you propose, so I hope this helps.

The "main" repo that we have forked from (the HL7 AU base IG) already does auto building and there is no talk about building from branches other than master. It is only that our forked copies will have our proposed work contained in various branches that we wish to have rendered via auto-building. Once these PRs are accepted it is all merged into master. So assuming that I understand correctly, the latter option of asking fork authors to explicitly, independently set up their forks to auto-build, seems OK. And I don't think that extra work is a problem.

However, it would be good to run this past some folk who are less noobish that me!

thank you

Just a quick follow-up that this has been in place for a while now. You can navigate to your IG + /branches to see built content across branches.
