Invalid input source map when --source-map content is absolute path

[XHighIntell]

Uglify version (uglifyjs -V) 3.19.3

JavaScript input To make it simple, I have 2 files that are built from Typescript. file.js file.js.map

• file.js

  "use strict";
  var apps;
  (function (apps) {
  function abc() {
      console.log('23123');
  }
  function fn1() {
      abc();
  }
  apps.fn1 = fn1;
  function fn2() {
      abc();
  }
  apps.fn2 = fn2;
  })(apps || (apps = {}));
  //# sourceMappingURL=file.js.map

• file.js.map

  {"version":3,"file":"file.js","sourceRoot":"","sources":["../../Client/apps/file.ts"],"names":[],"mappings":";AAAA,IAAU,IAAI,CAWb;AAXD,WAAU,IAAI;IACV,SAAS,GAAG;QACR,OAAO,CAAC,GAAG,CAAC,OAAO,CAAC,CAAC;IACzB,CAAC;IAED,SAAgB,GAAG;QACf,GAAG,EAAE,CAAC;IACV,CAAC;IAFe,QAAG,MAElB,CAAA;IACD,SAAgB,GAAG;QACf,GAAG,EAAE,CAAC;IACV,CAAC;IAFe,QAAG,MAElB,CAAA;AACL,CAAC,EAXS,IAAI,KAAJ,IAAI,QAWb","sourcesContent":["namespace apps {\r\n    function abc() {\r\n        console.log('23123');\r\n    }\r\n\r\n    export function fn1() {\r\n        abc();\r\n    }\r\n    export function fn2() {\r\n        abc();\r\n    }\r\n}\r\n"]}

The uglifyjs CLI command executed: The below command works correctly

uglifyjs "file.js" --compress --mangle --source-map "content='file.js.map',includeSources,url='file.min.js.map'" --output "file.min.js"

But when I use absolute path to the javascript and source map files (content is not changed). I got errors

npx uglifyjs "E:\My Life\OneDrive\Projects\Typescript Template 2\wwwroot\apps\file.js" --compress --mangle --source-map "content='E:\My Life\OneDrive\Projects\Typescript Template 2\wwwroot\apps\file.js.map',includeSources,url='file.min.js.map'" --output "E:\My Life\OneDrive\Projects\Typescript Template 2\wwwroot\apps\file.min.js"

JavaScript output or error produced.

Somehow, the cli still needs to escape characters like in javascript to make it work.

--source-map "content='E:\\My Life\\OneDrive\\Projects\\Typescript Template 2\\wwwroot\\apps\\dashboard\\dashboard.js.map',includeSources,url='dashboard.js.map'"

That is working as expected − content's value is JavaScript string literal, i.e. you need to escape the back-slash (\)
