Language type json #298

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Is there a way to get a formatter for json? lang-js does not quite work, since 
the keys and value are all the same color (strings).

I would love to have a way to set the keys color, and values color.

Thanks.

I was also hoping that the keys and values would be differentiated, but they 
are not.

Something like

PR['registerLangHandler'](
    PR['createSimpleLexer'](
        [
         [PR['PR_PLAIN'],       /^\s+/, null, '\t\n\r '],
         [PR['PR_KEYWORD'],     /^(?:true|false|null)\b/, null, 'tfn'],
         [PR['PR_LITERAL'],     /^[+\-]?(?:0xX[0-9a-f]+|(?:\d+|\d*\.\d+)(?:e[+\-]?\d+)?)/, null, '+-0123456789.'],
         [PR['PR_PUNCTUATION'], /^[,:{}\[\]]+/, null, ',:{}[]']
        ],
        [
         // A string followed by a colon is additionally a key.
         ['lang-jsonkey',       /^(\"(?:[^\n\r\\\"]|\\\S)*\")\s*:/],
         [PR['PR_STRING'],      /^\"(?:[^\n\r\\\"]|\\\S)*\"/]
        ]),
    ['json']);

PR['registerLangHandler'](
    PR['createSimpleLexer'](
        [
         // Apply the classes str and key to the key.
         [PR['PR_STRING'] + ' key', /^[\s\S]*/, null, '"']
        ],
        [
        ]),
    ['jsonkey']);

should do it, but it runs into the problem that many people use the word "JSON" 
for things that are not quire JSON like

    myJsonPCallback({ ... })

    [new Date(2014, 1, 1)]

    { /* Comments are fun */ }

    { 'single quoted keys are fun': true, but: "whatsMoreFun?", unquotedKeys: true }

    /* Math is hard! */ [NaN, Infinity]

Defining JSON mode strictly is hard.  Reusing JS mode neatly side-steps all 
those issues, but colon is overloaded in JS.
