Jsoneditor: Add readOnly for mode=code

[cope]

We are adding the 'jsoneditor-readonly' class to make the jsoneditor look like mode=code, but readOnly.

It would be nice if there was a _proper_ way to accomplish this, as well as to specify a readOnly theme. For example, I would love to use eclipse theme for regular code mode, and then dawn theme for code mode which would then be readOnly=true...

One can see here that the Ace editor has readOnly as an option. It would be nice if this was also available in the jsoneditor.

If you want to do custom configuration of the Ace editor that JSONEditor uses when in mode code, you can do so in two ways:

• Provide your own instance of Ace via the option ace (see docs).
• When the editor is in mode code, you can access the internal Ace editor via editor.aceEditor.

Does that help?

Yes! Awesome, thanks!

@cope _how do you achieve it?_... I was trying to pass an instance of Ace via the ace option, but to instantiate it seems to need a div element 🤔

@CicherMK did you see the https://github.com/josdejong/jsoneditor/blob/develop/examples/08_custom_ace.html example?

Thanks @josdejong for your response !

I forgot to mention that I'm using jsoneditor-react, which in turn uses the brace version of Ace Editor.

Anyways, checking Ace Editor's documentation, it says that you need to pass the id of the DOM's containing element:

But:

🤔

[josdejong]

JSONEditor creates it's own instance of Ace editor because it has to bind it to a DIV element that is created by JSONEditor itself. Looking at the package.json of react-jsoneditor it looks like it uses [email protected], which switched from brace to ace-builds, so it should not rely on brace anymore.

What you can probably do is pass your own edit factory function to work around any difference between differing versions of ace, like:

render() {
  const myAceFactory = {
    edit: function (domElement) {
      // create your own Ace instance, bind it to the provided DOM element, return it
    }
  }

  return (
    <Editor
      ace={myAceFactory}
      // ...
    />
  )
}

Thanks @josdejong !!, it works! 🤓🤙

The only thing, I had to use an ugly setTimeout:

otherwise, it just not works.... maybe is not the nicest approach, but I can live with that 😜
(at least for now)

_Thanks!!_
