casual pollutes the global momentjs instance with Norwegian locale #77

Open dan-weaver opened 6 years ago

dan-weaver commented 6 years ago

Looks like when we import casual in our test framework it alters the global moment 's locale setting. All our modules under tests then decide to humanize dates in norwegian instead of english (the default). Should casual use "instance level" locale methods as described here: https://github.com/moment/momentjs.com/blob/master/docs/moment/06-i18n/02-instance-locale.md

I'm happy to submit a PR if someone can confirm this what should be done.. Looks like a small set of changes needed: https://github.com/boo1ean/casual/search?utf8=%E2%9C%93&q=moment&type=

Oops I appologize.. This may only be a casual-browserify bug.. i thought casual-browserify depended on casual.. If that's not the case I can move this issue?

I'm still encountering this problem as well, on using casual-browserify. Is the repo owner open to pull-requests for this issue?

Search on GitHub forks do not work. This error still persists on the casual-browserify branch as seen here.

I agree that the locale should be set at an instance level. The scope for the variable I think can either be:

  1. Stored on the provider object scope (pros: we cache it instead of reproducing it again and again each time we need to format something; cons: we consume memory on the provider) or

  2. we just construct a new moment() each time we need to format the date (pros: no memory held for the moment instance; cons: we need to construct an object each time a date is generated).

I am not certain which is the wiser decision. Seeing as this is a fake data generator, choice 2 scales the more fake data (of type date) is created, while choice 1 is limited to the number of providers (constant 15). Given that, I'd go for choice 1 instead.

Interested to hear anyone's thoughts on this.

I started with the changes here but am unsure how to proceed with changing the usages of the providers.
