ReferenceError: _ is not defined with coffescript

[dcsan]

I've created a package which uses the collection-helpers package, but i'm getting some very indecipherable errors.

error is around _ not being defined inside collection-helpers*

Ensure dependencies...

I tried adding underscore even to my own package:

Package.on_use(function(api) {
    api.export(['Chatbots', 'Botrules']);   
    api.use(['coffeescript', 'underscore', 'collection-helpers']);
    api.add_files(['collections.coffee', 'Chatbots.coffee', 'Botrules.coffee', 'globals.js']);
});

I'm guessing this maybe something coffeescript related :(

following this issue
http://stackoverflow.com/questions/23281235/coffeescript-namespace-exports-in-meteor-custom-packages

I also tried using a separate globals.js

this is with meteor 0.8.1.1

have collection-helpers succesfully been used in other packages?
i guess the next thing is to rewrite everything in vanilla .js >.<

Hmm, it might actually be that I haven't defined api.use('underscore') with collection-helpers' package.js. Would you mind giving that a try?

[dcsan]

yep, that seemed to fix it! i thought underscore was included by default with meteor bootstrapping...

[dcsan]

do you want me to make a PR?

as i'm sure you know just replacing this:
https://github.com/dburles/meteor-collection-helpers/blob/master/package.js#L6

Package.describe({
  summary: 'Collection helpers'
});

Package.on_use(function(api) {
  api.use(['underscore']);
  api.add_files('collection-helpers.js', ['client', 'server']);
});

Thanks @dcsan
