I guess for some internal technical reason it's normal that the initial console.log() doesn't actually show up on the Console on plug-in installation (because it runs from a iframe?), even though the console.log() from inside _computeProblems() does? I found this confusing.
If such a contribution would be welcome
, I (or someone else..) could make it give better error messages with fine grained location using e.g. https://github.com/arc90/jsonlintdotcom
(MIT license - OK?).
How would one actually contribute this - pull request on GitHub? Gerrit (I've never used it!) ?
