I would like to use StackTraceJS to show errors to my users in the code editor.   My code is minified using Webpack/Uglify, but user code is not.  User code is executed in a sandboxed iframe.  \r\n\r\n## Expected Behavior\r\nI expect that StackFrameJS should parse \"anonymous\" errors correctly.\r\n\r\n## Current Behavior\r\nStackFrameJS does not parse anonymous errors like below, nor return the correct line number.\r\n\r\nSample User Code (should throw an error):\r\n![image](https://user-images.githubusercontent.com/369807/27046674-2e7b439e-4f5a-11e7-9498-749fc568d38f.png)\r\n\r\nMy code is executed like this\r\n```\r\n    let runFunction = function (p) {\r\n      let f = null;\r\n      try {\r\n        f = Function(\"p\", code)\r\n        f(p);\r\n      } catch (error) {\r\n          StackTrace.fromError(error).then(sr =\u003e {\r\n          window.parent.postMessage({sr, type: \"err\"}, \"*\");\r\n        })\r\n\r\n      }\r\n    }\r\n   // call runFunction\r\n  runFunction(...);\r\n```\r\n\r\nThe stack trace looks like this (in Chrome)\r\n```\r\nReferenceError: hi is not defined\r\n    at eval (eval at runFunction (http://localhost:8080/packs/iframe.js:5669:21), \u003canonymous\u003e:4:9)\r\n    at runFunction (http://localhost:8080/packs/iframe.js:5670:17)\r\n    at e.Sketch.sketch.attachFunction (http://localhost:8080/packs/iframe.js:5722:17)\r\n    at e.Sketch.attach (eval at webpackJsonp.679.module.exports (http://localhost:8080/packs/iframe.js:11868:8), \u003canonymous\u003e:43:267)\r\n    at Ir (eval at webpackJsonp.679.module.exports (http://localhost:8080/packs/iframe.js:11868:8), \u003canonymous\u003e:1417:89)\r\n    at eval (eval at webpackJsonp.679.module.exports (http://localhost:8080/packs/iframe.js:11868:8), \u003canonymous\u003e:1415:106)\"\r\n```\r\n\r\nThe parsed stack trace looks like this (first line)\r\n![image](https://user-images.githubusercontent.com/369807/27046606-f1193394-4f59-11e7-8c0a-0e7baa0c1cc2.png)\r\n\r\n\r\n\r\n## Steps to Reproduce (for bugs)\r\n\r\n## Context\r\n\u003c!--- How has this issue affected you? What are you trying to accomplish? --\u003e\r\nI am trying to use StackTrace to parse and show JS errors to a user in a browser editor (Monaco)\r\n\r\n## Your Environment\r\n\u003c!--- Include as many relevant details about the environment you experienced the bug in --\u003e\r\n* stacktrace.js version: 2.0\r\n* Browser Name and version: Chrome 58\r\n* Operating System and version (desktop or mobile): OS X Sierra 10.12.5\r\n\r\n\r\n## Possible Solution\r\nSuggest improving the parser to handle nested / anonymous stack traces\r\n\n\n---\n\n@eriwen commented on [Sat Aug 12 2017](https://github.com/stacktracejs/stacktrace.js/issues/194#issuecomment-322003767)\n\nThanks for the issue. Error parsing is done in `error-stack-parser`, so I'm moving the issue to that project.\n\n","author":{"url":"https://github.com/eriwen","@type":"Person","name":"eriwen"},"datePublished":"2017-08-12T20:24:18.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/38/error-stack-parser/issues/38"}
