Description

I use Monaco Editor and React Monaco Editor to build our own editor.

An event onChange is emitted when the content of the current model has changed, where we can get newValue of the model.

Now, I would like to get information of comparison of newValue and oldValue: for instance, insertion of certain characters at a location, deletion of certain characters at a location, etc.

Does anyone know how to get these information?

Perhaps editor.onDidChangeModelContent((a) => console.log(a)); is what you want

{
    "changes": [
        {
            "range": {
                "startLineNumber": 9,
                "startColumn": 6,
                "endLineNumber": 9,
                "endColumn": 6
            },
            "rangeLength": 0,
            "text": "o",
            "rangeOffset": 74,
            "forceMoveMarkers": false
        }
    ],
    "eol": "\n",
    "versionId": 7,
    "isUndoing": false,
    "isRedoing": false,
    "isFlush": false
}
