Add out of the box support for YamlLint and YamlFix

[guenth39]

Is your feature request related to a problem? Please describe.
For me, it's quite difficult at the moment to write custom lints for yaml files. To write a lint is possible, but I can't make the fixes work. It would be nice if the package could offer a simple solution for that, like with DartLint and DartFix.

Describe the solution you'd like
Add corresponding YamlLint and YamlFix class.

Describe alternatives you've considered
Add a guide on how to write linter rules for files others than dart.

It is low priority for me. But sure

If you're following to work on this, I'm open to guiding you on it :)

Do you have any thoughts on this?

Linting yaml files kind of works, but the plugin doesn't get notified about updates to yaml files. I tried adding *.yaml to the interestingFiles field here, but that somehow broke yaml file linting completely.

dart_custom_lint/packages/custom_lint/lib/src/v2/custom_lint_analyzer_plugin.dart

Line 330 in b50bd2b

['*.dart'],

Ideally we pass in the globs from LintRule.filesToAnalyze, but I was just trying to get a proof of concept working.

Analyzer_plugin is likely the issue here. I'd suggest raising an issue on the dart sdk for that. There's likely already one

Actually it looks like custom_lint isn't working as a path dependency. It doesn't seem to work in the dart_custom_lint project at all either, so it's not just my project. Do you have any ideas how to fix that?

[rrousselGit]

You need to edit the tools/analyzer_plugin/pubspec.yaml

dart_custom_lint/packages/custom_lint/tools/analyzer_plugin/pubspec.yaml

Line 14 in 90365e2

# dependency_overrides:

You may have to clear your pub cache after editing the pubspec too. Or your change may not get picked up.

Analyzer_plugins are ... let's say ... not exactly easy to use.

[Rexios80]

Is that in the documentation somewhere? I looked but couldn't find it. Maybe we should add this to a CONTRIBUTING.md file?

[rrousselGit]

There's a TODO in the pubspec, but a CONTRIBUTING.md could be good too.

[Rexios80]

I think I got it kind of working by symlinking my fork of custom_lint into the pub cache, but I still can't get yaml lints to update in real time. I don't have the bandwidth to diagnose this at the moment, so I'm giving up for now.

As I mentioned, the update issue is likely not from custom_lint
