To Reproduce Provide a minimal source code example AND how you are invoking NUglify

Minified output or stack trace Provide the minfied code which is erroneous or the stack trace in case of an exception

Excepted output code Provide the expected minified code

This bug occurs with latest version (1.20.7) and also version 1.16.1 The parser get lost while parsing methods or call that has the pattern URL( Like return $h.objUrl.createObjectURL(data); Just try to parse https://github.com/kartik-v/bootstrap-fileinput/blob/master/js/fileinput.js return $h.objUrl.createObjectURL(data); becomes return $h.objUrl.createObjecturl(../data);

I'm using latest version NUglify-1.21.9

Describe the bug NUglify is parsing a specific pattern "URL(" wrongly messing the JS code

To Reproduce .NET 8

1-Startup.cs call: pipeline.AddJavaScriptBundle("/js/jqueryExtensions.js", ServiceHelper.GetCodeSettings(), "wwwroot/Scripts/jQuery/Extensions/DataTables/Buttons/*.js").UseContentRoot().AdjustRelativePaths().AddResponseHeaderCacheControl();

2-ServiceHelper.GetCodeSettings == return NUglify.JavaScript.CodeSettings.Pretty()

3-Just NUglify any JS with this specific pattern like https://cdn.datatables.net/buttons/3.1.2/js/buttons.html5.js

Minified output or stack trace Example 1 Original JS code: get_URL().revokeObjectURL(file); Result: get_URL().revokeObjecturl(../file);

Example 2 Original JS code: reader.readAsDataURL(blob); Result: reader.readAsDataurl(../blob);

1. The error occurs regardless off [MinifyCode=True/False]
2. I'm using NUglify indirectly by AddWebOptimizer

Looking at the Project code, looks like this is a feature of CssParser (method ScanUrl) So why a CssParser is being used in a JS code?

I created a simples console app to test calling directly NUglify with the file in question and the error does not occurs

var data = System.IO.File.ReadAllText(@"C:\\TEMP\\fileinput.js");
var x = NUglify.Uglify.Js(data, NUglify.JavaScript.CodeSettings.Pretty());
System.IO.File.WriteAllText("C:\\TEMP\\fileinput.js.nug", x.Code);

Input:

    createObjectURL: function (data) {
      if ($h.objUrl && $h.objUrl.createObjectURL && data) {
        return $h.objUrl.createObjectURL(data);
      }
      return "";
    },

NUglify.Pretty:

            createObjectURL: function(data)
            {
                if ($h.objUrl && $h.objUrl.createObjectURL && data)
                {
                    return $h.objUrl.createObjectURL(data)
                }
                return ""
            },

NUglify.Min:

        createObjectURL: function(n) {
            return t.objUrl && t.objUrl.createObjectURL && n ? t.objUrl.createObjectURL(n) : ""
        },

Generated by WebOptimizer:

    createObjectURL: function (data) {
      if ($h.objUrl && $h.objUrl.createObjectURL && data) {
        return $h.objUrl.createObjecturl(../data);
      }
      return "";
    },

So I think the problem is not related to NUglify itself Any help would be appreciated

The error was totally mine I was using AdjustRelativePaths with JS files and this method if only for CSS
