Add automatic Closebrackets function to Codemirror.

[damianavila]

This is a trivial change to add automatic close of brackets {, [ and ( to code cells...
This behaviour is extensively spread across multiple IDE and code editors, and I think it worth to make it a default option.
I tested in live and I really like the millisecond I do not spent looking for the closing bracket 😉

Thoughts?

I think a couple of us should play with this to see what we think.

I don't think it should be default. Julia have asymetrical bracket for semi-open interval IIRC. like [0:3) @stevengj ?

I don't know too much about Julia, so this asymmetrical brackets are used very frequently?
Because, if it is not... probably you are saving more time with the automatic closing than without it.
I think it is a matter of balance between how many times use the asymmetric brackets and how many use the symmetric ones...

Shouldn't codemirror defaults be tied to the language? Already, you should have different syntax highlighting for julia vs. python. It seems like in the same manner, you should also be able to have different plugins loaded.

Julia doesn't have asymmetrical brackets. (There was some discussion of this notation, but it was ultimately rejected: JuliaLang/julia#2040)

Ok, then +1 for me.

Comments? How do you feel it? Thanks.

I just pulled this branch and I really like it, great idea to enable this @damianavila - 👍 from me too. Will let someone else merge it though.

[davidtrem]

Please merge ! I just can't live without this feature now :-)

[damianavila]

Thanks!
