JSON5 support

[giacomorebonato]

Feature

It would be nice if the project worked also with other more relaxed JSON syntax, like JSON5. What do you think?

Alternative solutions or implementations

I see that jsonc-parser doesn't support JSON5 but jsonc-eslint-parser does and maybe it can be leveraged for unlocking this support.

Other context

Many configuration files are in JSON5 format or exporting just a JS object.
This feature will bring onboard more users interested on using JSON Crack for different reasons.

Converting JSON5 to JSON will be easier, but monaco editor doesn't have JSON5 language support from what I've seen so that will be hard. We need to find a way to integrate JSON5 to monaco editor.

I am using this configuration, very minimal but OK for my needs:

monaco.languages.register({ id: 'json5' })

monaco.languages.setMonarchTokensProvider('json5', {
    "tokenizer": {
        "root": [
            [/{\s*/, "delimiter.bracket"],
            [/}\s*/, "delimiter.bracket"],
            [/\[/, "delimiter.square"],
            [/\]/, "delimiter.square"],
            [/:\s*/, "delimiter.colon"],
            [/,/, "delimiter.comma"],
            [/true|false|null/, "constant"],
            [/"(?:[^\\\"]|\\.)*"/, "string"],
            [/'(?:[^\\\']|\\.)*'/, "string"],
            [/-?(0|[1-9]\d*)(?:\.\d+)?(?:[eE][+-]?\d+)?/, "number"],
            [/\/\/.*/, "comment"],
            [/\/\*[\s\S]*?\*\//, "comment"]
        ]
    }
})
