Level colors do not show up when using foreman since 1.0.0

Since upgrading from 0.9 to 1.0, the level colors are no longer displaying correctly when running the node app with foreman.

For the test file index.js

var winston = require('winston');

var logger = new (winston.Logger)({
  transports: [new (winston.transports.Console)({ level: 'debug', colorize: true })]
});

logger.debug('debug message');
logger.info('info message');
logger.warn('warn message');
logger.error('error message');

and the Procfile:

web: node index.js

Using 0.9.0 I get the following:

Whereas 1.0.0 yields no colors when run with foreman:

Hmm. On further investigation, it looks like this is an issue with colors/safe.

Updating index.js to the following:

'use strict';

var winston = require('winston');
var colors = require('colors/safe');

var transport = new (winston.transports.Console)({ level: 'debug', colorize: true });
var logger = new (winston.Logger)({
  transports: [transport]
});

logger.debug('debug message with ' + colors.magenta('colored output'));
logger.info('info message with ' + colors.magenta('colored output'));
logger.warn('warn message with ' + colors.magenta('colored output'));
logger.error('error message with ' + colors.magenta('colored output'));

Yields the following with 0.9:

I'll open an issue with the colors library instead.

Issue moved to colors library: Marak/colors.js#121

There seems to be a workaround: By setting colors.enabled to true at any time. They seem to detect if colors are supported and initialize colors.enabled with the result, and within the foreman command they end up detecting that color is not supported.

Thanks @Darkhogg that works a treat!

I opened a PR so hopefully this will get merged in.

Fixed in #751. Released in winston@2.1.1
