Where can I find the list of rules?

Is there a published list of all the linter rules? I couldn't find a reference to it in the documentation.

Alternately, is there a sample project that (on purpose) triggers every possible linter error?

Here are all the rules:
https://github.com/arduino/arduino-lint/blob/main/internal/rule/ruleconfiguration/ruleconfiguration.go#L60-L2859

You can get details on all the rules that are run for a given project type and tool configuration by running arduino-lint --format json --verbose or print it to a file using the --report-file flag.

That would be one seriously messed up platform! It actually wouldn't be possible to trigger all of them from a single project because some are mutually exclusive.

There is an individual test project for each rule violation here:
https://github.com/arduino/arduino-lint/tree/main/internal/rule/rulefunction/testdata
It's pretty fun to run arduino-lint --recursive on that folder!

OK, great. I'll leave this issue open in case you want to convert it to a "publish the rules on a webpage" request, but my needs here are met.

Hi @ianfixes. Thanks for your excellent suggestion! It took a long time to get around to it, but we have finally added documentation for every rule to Arduino Lint's website:
