Checklist (adding a new tool):

• If it's a linter it was exported in linter/init.lua
• The tool was added to the README
• I do not wish to write a test, but I can confirm that it works on my machine OR I have written corresponding tests for the tools I added. (don't worry if you didn't write a test, it's just nice to see the green check mark)

This PR also closes #38

I am not sure about the jq config, shouldn't jq . do the trick?

[231tr0n]

@xiaoshihou514 I actually tested it and it works. You can do it like this as well cat somefile.json | jq -M

[xiaoshihou514]

Yes, but do we really need this flag

[231tr0n]

Yes, but do we really need this flag

It outputs colors without that flag. So we might end up having terminal escape characters for colors afaik. I did not test it though without the -M flag.

[xiaoshihou514]

By default, jq outputs colored JSON if writing to a terminal. You can force it to produce color even if writing to a pipe or a file using -C

Ohh it works like that is it, ok then should i remove the -M flag then?

[xiaoshihou514]

I have no experience with other tools, so they look good to me.

[xiaoshihou514]
