WIP: Emoji extension

[markhalliwell]

This is a WIP for #421, an emoji extension implementation using https://github.com/unicorn-fail/emoji

I haven't yet actually tried this to see if it works as expected, this work is based solely on IDE reliance on API implementation.

This, currently, includes a single test as a POC

This is looking great so far!

I took a stab at implementing this for a project I've been working on. It's functional, but lacks a full 1:1 mapping of emoji aliases to Unicode CLDR names. I felt preserving the official names was important for internationalization.

The actual parsing/rendering of emojis should be handled by a separate library. That is why we're creating https://github.com/unicorn-fail/emoji (will be migrated to thephpleague namespace after its documentation is finalized).

This issue will merely be an extension that implements that.

Yeah, I agree! My version of building the data files is no where as far along as yours; and doesn't include the generation script because it's not pretty. 😆

Looking forward to switching over to this one soon.

@giberti I'm taking a look at your extension until this is ready! :)

Is there any update on this PR and in turn an Emoji extension for commonmark ? This is the one feature that is stopping us for moving over to commonmark fully in our project.
