Serializing service config to YAML

Serializing service config to YAML

[TakeV]

[-- Attachment #1.1.1: Type: text/plain, Size: 521 bytes --]

Hello there!

I am attempting to create a service to run a package (specifically this 
https://github.com/superseriousbusiness/gotosocial) via shepherd. I have 
the config defined as specified in the complex configuration part of the 
manual, and I was wondering if there are any existing examples of 
serializing configurations to YAML? Right now I have everything passing 
directly into the command line, and being able to serialize to a config 
and pass that in would be much cleaner, I believe.

Thanks!

Grepping through the source code didn't reveal any meaningful references
to yaml.
There is an ad-hoc config generator in gnu/services/web.scm that
generates a tailon-config.yml, but at a quick glance it doesn't seem to
be a generic converter.  But maybe it's a good starting point?
I checked guile-libyaml but it is only a parser and doesn't support
serializing Scheme into YAML as far as I can tell.

Hi,

We at RDE have custom serializers for various document formats that upstream doesn't seem to entirely agree on.  I've recently proposed a YAML serializer in here https://lists.sr.ht/~abcdw/rde-devel/%3Ccover.1678531169.git.contact%40conses.eu%3E that should be merged in pretty soon. Hope it helps.

This is absolutely perfect! Thank you for the link.

You can always just cheat a bit by using the fact that pretty much any JSON is a
valid YAML.  So just serialize to that and name the file .yaml.  ^_^
