I noticed that when I run a

meltano

command that updates

meltano.yml

, that it reformats the YAML. Can I turn that off? I’d prefer different indentation settings.

What version of meltano are you on? That should have been addressed in a version we released earlier this year

$ meltano --version
meltano, version 2.10.0

installed today with

python -m pip install --upgrade meltano

on Python 3.9.11

oh you mention indentation settings - not order. hmm - @edgar_ramirez_mondragon I’m guessing Ruamel doesn’t respect user set indentation depths?

specifically, I would prefer:

environments:
  - name: dev

and the CLI commands change this to

environments:
- name: dev

I wonder if that’s a ruamel setting we can have folks set 🤔 would you mind filing an issue @Matt Menzenski? I suspect this behavior is currently “expected” but that’s not to say it’s ideal

sure thing - happy to try to contribute also

I'm not 100% sure if Ruamel is able to preserve/honor the user's preferred indentations. Would be good to confirm that. If we change the default, we'd have to think carefully on the best default experience and whether it is appropriate to make a one-time global change. Related SO answer

Yup, Ruamel is conforming all indentations to

mapping=2, sequence=2, offset=0

by default. The preference above would mean having

mapping=2, sequence=4, offset=2

. That would be called globally here: https://github.com/meltano/meltano/blob/e51aa22626a6836306e5eb9d93544a826c3d439e/src/meltano/core/yaml.py#L17-L19 Ruamel docs: https://yaml.readthedocs.io/en/latest/detail.html#indentation-of-block-sequences
