Documentation (please check one with an [x])

• I have updated the documentation, or
• No documentation update is required

How I've tested my work (please select one)

I have verified these changes via:

• Code inspection only, or
• Newly added/modified unit tests, or
• No unit tests but ran on a real repository, or
• Both unit tests + ran on a real repository

Needs linting errors to be fixed, else LGTM.

[secustor]

Please use JSON, that way we get code highlighting in the documentation.

[SirUli]

The original codefences in that document were actually partly json5 (which is among the supported languages of github), hence I thought that this is the solution. Will change back and update the code to json compliance.

[secustor]

The linting fails because of the first JSON block

[SirUli]

Sorry - i had the codeblock in my editor replaced but apparently not commited. Now finally done. Sorry again!

[SirUli]

Hope now we got it finally, the output of the task from prettier wasn't super helpful but i believe it was the spaces in the code block.

[secustor]

You can run yarn run lint-fix to fix most issues.

So instead of a quick contribution this turned into a crazy undertaking. Btw the linter wanted to have this:

# renovate: datasource=custom.nexus_generic depName=something versioning=loose
something_version: '77'

instead of

# renovate: datasource=custom.nexus_generic depName=something versioning=loose
something_version: "77"

which led to a change of the overall regex etc. Very opionated style... anyway now it should be complete finally.

[SirUli]

Thanks so much for your help and patience @secustor !

[secustor]

You're welcome. Thanks for your contribution!
