My App has a few grammar modes defined in global vars:

var ins_mode = AceGrammar.getMode({
    "RegExpID": "RE::",
        "Style": {
    //...
});

var ycd_mode = AceGrammar.getMode({
    "RegExpID": "RE::",
        "Style": {
    //...
});

var aoi3_mode = AceGrammar.getMode({
    "RegExpID": "RE::",
        "Style": {
    //...
});

var mmd_mode = AceGrammar.getMode({
    "RegExpID": "RE::",
        "Style": {
    //...
});

When I try to set the editor to a different mode, ace.js gave me this error:

let modeStr = getMode() //This return either "ins_mode", "ycd_mode" ... in string
myAceEditor.session.setMode(window[modeStr]);

ace.js?nocache=nonce_1_1657893450835_623:11570 
        
       Uncaught ReferenceError: window is not defined

I think it is because I pass global value to the editor.session.setMode(), and somehow it would mess with ace.js window global object.
Is there anyway that I can set editor to a different AceGrammar mode without produce this error?

My use case is as such. Given a json schema of some (static, pre-defined) variable names and what types of data they can contain (floats, strings, ints, bools), I need to have ace show the user that assigning an int to a string-type variable is wrong.

I am currently parsing the json and adding identifiers to the lexer with a regex showing options of specific variable names like so:

"Lex" : 
    "identifier_float" : "R::/(x1|xn|y1|yn|z1|zn|grid_motion_rate|pert_rms|pert_peak|pert_band|TKE)/"

And in the syntax part I state that the correct syntax for float-type variables is:

"Syntax":
    "literal_property_float"   : "(identifier_float) '=' (float | number)"

(where float and number are defined in Lex)

Ace seems to understand that I require '=' and then a float/number, but it doesn't recognize the identifier_float name requirement.

How do I use ace-grammar to have Ace understand that a given variable name has a given data-type requirement?

If this isn't the correct place to ask a question, please point me in the right direction.

It would be nice to publish your library for easy use.

Since the Style Model seems a bit... plain, so I think you could make it as optional by adding the style property to the Lex Model.
So instead of:

{
  "Style": {
    "identifier": "style1",
    "property": "style2"
  },
  "Lex": {
    "identifier": {"tokens": ["key1", "key2"]},
    "property": {
      "extend": "identifier"
    }
  }
}

Do this...

{
  //No need `Style` now...
  "Lex": {
    "identifier": {"style": "style1", "tokens": ["key1", "key2"]},
    "property:style2": {    //<= Maybe like this
      "extend": "identifier"
    },
    "property:block:style2": {    //<= Or make the `style` value as the third anotation?
      "extend": "identifier"
    }
  }
}

This is just an idea. Do you think if it is possible?

Thanks for the great extension!

What's the license to use and extend this project (it works great, by the way)?

It would make simpler contribution, versioning and publishing.
