Thank you for this report.

In except the defined properties of custom components, v-on:attrName and v-on:attrname are the same attribute, both become v-on:attrname. So this is not a bug. However, I agree it's inconvenient if we cannot get the raw data of key.argument easily. I will add new property raw.

{
    "type": "VDirectiveKey",
    "range": [
        21,
        34
    ],
    "loc": {
        "start": {
            "line": 2,
            "column": 9
        },
        "end": {
            "line": 2,
            "column": 22
        }
    },
    "name": "bind",
    "argument": "foobar",
    "modifiers": [],
    "raw": {
        "name": "bind",
        "argument": "FooBar",
        "modifiers": [],
    },
    "shorthand": false
}

@mysticatea thank you, its going to be easier to get it from raw than accessing source code & parsing it by my own.

I added some properties (v2.0.0-beta.2...master#diff-60a3c5d4caa5a12bdd8e920349affeb7). Please use v2.0.0-beta.3.

• VIdentifier#rawName
• VDirectiveKey#raw
• VElement#rawName
