--harmony-proxies option not working

[JaKXz]

This is my mocha.opts file in my test/ folder:

--compilers js:babel/register
--require mocha.conf.js
--harmony-proxies

I'm using mocha v2.3.4, and node v5.1.0 and I get the error:

  error: unknown option `--harmony-proxies'

EDIT: In fact, none of the --harmony options are working.

Looks like a regression in 2.3.3. Works in 2.3.2.

@danielstjules I don't know about that, I can't reproduce it using his setup.

@boneskull I think it's a regression :(

$ cat test/mocha.opts
--harmony-proxies
dstjules:~/Desktop
$ mocha --version
2.3.2
dstjules:~/Desktop
$ mocha


  0 passing (4ms)

Looks like it's my fault, sorry: c4647bf

@JaKXz Note that this still works by passing options to the bin. So in the meantime, you can do:
mocha --harmony-proxies

I'll have a fix for this tomorrow.

[JaKXz]

@danielstjules thanks!

[danielstjules]

Nevermind, this isn't a regression in that relase. Any node-specific flags (harmony, etc) need to be passed via CLI, and not placed in mocha.opts. When passed via CLI, bin/mocha will spawn an instance of bin/_mocha with the harmony flags.

[danielstjules]

This was a result of #1910 But we can't remove getOptions from _mocha, due to #1645 I think an immediate solution would be to check whether or not the options have already been loaded

[danielstjules]

Fixed in master. Thanks again! :)

Thank you, @danielstjules! and Merry Christmas/Happy Holidays/etc 🎄 🎅 ✨

Harmony flags doesn't work for me while using bin/_mocha (required by istanbul)

  "devDependencies": {
    "chai": "^3.5.0",
    "istanbul": "^0.4.2",
    "mocha": "^2.4.5"
  },

I'm trying --harmony_default_parameters node flag
Reproduction here

Obs.: it does work for bin/mocha binary

[boneskull]

@josmardias mocha exists so that _mocha can be run with node flags. You will need to execute istanbul with node flags.
