Ability to disable emitting anchors

[Piotr Krzemiński]

Hi!

I've just started using snakeyaml to emit YAML in my library for authoring GitHub Actions workflows. Unfortunately, GitHub doesn't support anchors, and snakeyaml seems to be very eager to emit them: https://github.com/krzema12/github-actions-kotlin-dsl/issues/416

Could you add a configuration option to disable emitting anchors? Are you open to having such feature in the lib? I can contribute.

Alternatively, is there some workaround that I could use to patch my library?

Thanks,

Piotr

A PR is welcome !

Cool, I'll prepare one.

One more question: when do you plan to release the next version? From what I see, the releases are rather rare which worries me a bit.

We are going to release next week

Ok, cool. To speed up iteration on the PR: do you have a vision where this flag can be added? I see at least two classes that deal with anchors. Any implementation hints greatly appreciated.

I went another path: snakeyaml-engine and event-based approach where I have greater freedom when emitting YAML. I just produce subsequent keys with {} values and no anchors are created. From my PoV, this feature request just got way less critical.
