Validate JSON when there's a parsing error about jsonview

I'd love to see this but even if you could highlight parts that are invalid it would help greatly with figuring out why a file doesn't view. Maybe a "relaxed" mode could be selected that shows files somewhat pretty even with invalid JSON. I have some files that should be JSON but aren't correct and they're quite large (250K) so when I open them and they don't work I'm stuck with a real headache trying to sift thru and find out what's wrong. Bold or Red marked areas would make this so much easier to fix. Thanks.

edit: Oh, I see now that it's not supporting unicode strings. I guess that's at least part of the problem. Any possibility to add support?

Having explored this a bit further I see now that my file is not truly a JSON file. It only looks similar. It's actually a Python AST format which has a few small differences designed just to make us go syntax crazy.

Well, a Python object view extension or mode seems to be warranted then.

Differences I noticed are:

• single quotes strings
• Capitalized booleans (True not true, False not false)
• Possible None values which would be "None" in JS
• Unicode strings eg. u"text"

JSONView does support unicode, but just in regular strings, not Python crazy-format. You could fork JSONView and build your own Python-format-viewer extension though.

Not a bad idea. I'd probably implement it as a preference as I wouldn't want to have two separate viewers and I can see still wanting JSON.

I'd make a completely new extension that you can distribute. Anyway, it's not JSON, so you'll need to look for a different MIME type.

could JSONView indicate that there is an error? i've hit a bug in MOXy and it's taken me a week to realize that JSONView is throwing away duplicated object members. Thanks

[bhollis]

If there is an actual error that Firefox's JSON parser can detect, we show it. We get no visibility into things like repeated object keys.

ok, thanks
