Ligature support

[kamek-pf]

Sublime added ligature support in build 3146.
Using FiraCode, here's what happens in Rust sources :

Ligatures work fine in other languages, and as someone pointed out in this discussion, we might want to look into the syntax definition itself.

Sublime Text Version

Sublime Text 3 (Build 3147)

Rust Enhanced Version

v2.2.0

Operating system

Arch

Expected behavior

Ligatures should work everywhere

Actual behavior

Some ligatures aren't applied

Looks like the pattwrn below would match the ! separately from the =

   - match: '\.\.\.|\.\.||[-=<>&|!~@?+*/%^''#$]|\b_\b'
      scope: keyword.operator.rust

I can sort it but i can't even figure out how to show ligatures 😅

[kamek-pf]

I didn't do anything special to make them work, they just showed up after the upgrade.
Make sure your build is 3146 or newer and use a font that support ligatures '_'

3146 is in the dev branch btw, stable is stuck at 3143

manged to enable FiraCode and fixed it, PR pending
