Thank you for your work on mdformat and plugins @hukkinj1!! ❤️ 🎉

I'm looking to adopt mdformat as well as this plugin, but the practice across the repository I work is to indent YAML sequences / lists differently than is currently hardcoded in this project.

My preference

yaml.preserve_quotes = True
yaml.indent(mapping=2, sequence=4, offset=2)

Current hardcoding
https://github.com/hukkinj1/mdformat-config/blob/2afc92ce3f93396e1bd5a42395debdf05af6deab/mdformat_config/__init__.py#L21-L29

I looked into ruamel.yaml's documentation regarding configuring it, and didn't find a simple way to do it without forcing this plugin to expose configuration options to pass onwards =/

I also didn't conclude it would be easy when I inspected the source code.

What do you think, would it be in scope of this project to expose some configuration to pass onwards to ruamel.yaml? My experience in general is that its really tiresome to have to do this 1:1 mapping of configuration, because its often no end to the amount of options you end up needing to map, so its nice if it can be done quite generic.

I would like to unselect formatting of TOML snippets, because IMO the result is not that good:

[build-system]
requires = ["pdm-pep517"]
build-backend = "pdm.pep517.api"

[project]
name = "package-name"
description = "The package description."
version = "0.1.0"
authors = [{name = "Timothée Mazzucotelli", email = "[email protected]"}]
license = "ISC"
readme = "README.md"
requires-python = ">=3.7"
keywords = ["some", "keywords"]
classifiers = [
    "Development Status :: 4 - Beta",
    "Intended Audience :: Developers",
    "Programming Language :: Python",
    "Programming Language :: Python :: 3",
    "Programming Language :: Python :: 3 :: Only",
    "Typing :: Typed",
]

...is formatted to:

[build-system]
requires = [ "pdm-pep517",]
build-backend = "pdm.pep517.api"

[project]
name = "package-name"
description = "The package description."
version = "0.1.0"
license = "ISC"
readme = "README.md"
requires-python = ">=3.7"
keywords = [ "some", "keywords",]
classifiers = [ "Development Status :: 4 - Beta", "Intended Audience :: Developers", "Programming Language :: Python", "Programming Language :: Python :: 3", "Programming Language :: Python :: 3 :: Only", "Typing :: Typed",]
[[project.authors]]
name = "Timothée Mazzucotelli"
email = "[email protected]"

Things I don't like in the formatted block:

• arrays start with a space, but do not end with one
• arrays are inlined (line breaks removed) (this is the most crazy one 😅)
• trailing commas are added to already inlined arrays
• trailing commas are not removed after inlining arrays
• inline mappings are moved after the current object
• no space is added before a moved mapping

I suspect you don't do anything special in this project and just load and re-dump the TOML data.

So in the end I'd just like to prevent TOML formatting and just keep JSON and YAML 🙂
