filename option in vm.runInThisContext function argument disabled

[freeneutron]

This code:

  vm= require('vm');
  vm.runInThisContext('console.trace()',{filename:'vmTest'});

gives such a output:

  Trace
      at [object Object]:1:9

But docapi says:
filename: allows you to control the filename that shows up in any stack traces produced.

It works for me, are you sure you're using the right version of node.js/io.js?

> vm.runInThisContext('console.trace()', { filename: 'vmTest' })
Trace
    at vmTest:1:9
    at Object.exports.runInThisContext (vm.js:54:17)
    at repl:1:4
    at REPLServer.defaultEval (repl.js:164:27)
    at bound (domain.js:250:14)
    at REPLServer.runBound [as eval] (domain.js:263:12)
    at REPLServer.<anonymous> (repl.js:392:12)

    at REPLServer.emit (events.js:169:7)
    at REPLServer.Interface._onLine (readline.js:210:10)
undefined

For example, on node v0.10, the second parameter is the filename string directly instead of an options object:

> vm.runInThisContext('console.trace()', 'vmTest');
Trace
    at vmTest:1:9
    at repl:1:4
    at REPLServer.self.eval (repl.js:110:21)
    at repl.js:249:20
    at REPLServer.self.eval (repl.js:122:7)
    at Interface.<anonymous> (repl.js:239:12)
    at Interface.emit (events.js:95:17)
    at Interface._onLine (readline.js:203:10)
    at Interface._line (readline.js:532:8)
    at Interface._ttyWrite (readline.js:761:14)
undefined

node v0.12+ is backwards compatible with the string argument. So you could just use that type of invocation if you need to also support v0.10.

Excuse me. My node has a version 0.10.40. To install it, I use a simple script:
curl --silent --location https://rpm.nodesource.com/setup | bash -
yum -y install nodejs

Ok, so then you will need to use the second solution instead: vm.runInThisContext('console.trace()', 'vmTest');.

Sounds like this has been answered. Re-open if necessary.
