• Electron version: 1.6.2
• Operating system: Windows 10 64-bit

Expected behavior

eval() should run in the current scope and be able to access global variables. The following script, which is executed on the main process (global scope), should produce no error (in fact, it does work properly in Electron v1.4.15).

eval(
  "const app = electron.app;\n"
+ "const BrowserWindow = electron.BrowserWindow;\n"
+ "app.on('ready', function() {\n"
+ "  mainWindow = new BrowserWindow({ ... });\n"
+ "});"
);

Actual behavior

Error occurs on the "new BrowserWindow" part saying BrowserWindow is not defined. The defined global variable BrowserWindow is not accessible inside the function.

As a workaround, I have to enclose the script inside an anonymous self-invoking function so that a local scope is created to avoid the problem.

eval (
  "(function () {\n"
......
+ "})();"
);
