Emoji REPL completion

To quote @jiahao:

These are the voyages of the flagship Julia. Its five-year mission: to explore strange new symbols, to seek out new codepoints and new characters, to boldly go where no language has gone before.

Happy April 1st

Should we also make 💯 a MathConst?

[sbromberger]

As long as we're allowed to propose PRs that assign math constants to these new symbols, I'm all in favor. 👍

ETA: damnit. @simonbyrne was quicker on the keyboard.

[sbromberger]

although 👍 might be more appropriate as an incrementer function :)

[jakebolewski]

julia> 💯
💯 = 100.0...

julia> fill(💯, (5,5))
5x5 Array{MathConst{:💯},2}:
 💯 = 100.0...  💯 = 100.0...  💯 = 100.0...  💯 = 100.0...  💯 = 100.0...
 💯 = 100.0...  💯 = 100.0...  💯 = 100.0...  💯 = 100.0...  💯 = 100.0...
 💯 = 100.0...  💯 = 100.0...  💯 = 100.0...  💯 = 100.0...  💯 = 100.0...
 💯 = 100.0...  💯 = 100.0...  💯 = 100.0...  💯 = 100.0...  💯 = 100.0...
 💯 = 100.0...  💯 = 100.0...  💯 = 100.0...  💯 = 100.0...  💯 = 100.0...

Love it!

[sbromberger]

Defining 👍 as a function appears to hang the REPL :(

[simonbyrne]

We actually probably don't want 💯 as a MathConst, as all the inequality functions assume that MathConsts are irrational. We could have const 💯 =100 though.

[jakebolewski]

Obviously this PR is just for fun, but it is entertaining enough that it might be worthwhile to have it as an easter-egg.

Is there a way to add completions at run-time so that using EmojiCompletions could be a thing?

[jakebolewski]

There might be a way, but the latex substitution claims the convenient \<tab> idiom.

[jakebolewski]

@Keno likes emojis.

[sbromberger]

man, I just did a build this morning. Now I get to rebuild. Thanks. :)

[hayd]

👍 Emojis are clearly the future.

Is the following a problem with my terminal or julia?

If you type, 👍 123 (without space), it looks fine, once you press return the 1 overlaps the 👍.

julia> 👍123<ENTER>

Perhaps this because the length(":+1:") == 1? (Should it be 2?)

I also see this if I tab complete two 👍👍 in a row.

[jiahao]

@hayd you've run into the notorious pizza/koala bug. #3721

[pao]

There might be a way, but the latex substitution claims the convenient idiom.

Ah, I see. I was hoping that those were themselves runtime extensible. But definitely in the "nice-to-have" category.
