Formatters that returns Promises

[triptec]

This is just how I could work I guess, thoughts?

With the state of the test suite this is something that might take some time to get this merged. This is to allow user-functions to be chained to the formatters right?

Nice idea, but there may be wide ranging implications with making formatters async that will require thorough testing to avoid breaking current code.

Well my use case is that if there is a link pasted in the editor I would like to substitute it with a [link src='' type=internal | external etc] and to be able to determine if it's a internal src I need to make a http get and therefor return a promise.

I guess most plugins won't need to return a promise and that works to, obviously we need to get the tests running, I might be able to help with that, just wanted to know if this is something you could see going in to the codebase.

I also would like to know if there's a better way to handle my use case but I still think it would be nice to have formatters able to handle promises if needed.

This might have a performance impact though and that could be a good reason not to make it work this way, I guess we could add async formatters instead of changing a current api.

Yeah, adding a specific async formatter is definitely going to be easier to get into production
