Unicode goodness for Scala code by using vim's “conceal” feature

Primary LanguageVimL

This syntax file displays unicode characters for some Scala operators and built-in functions, turning the following:

  foo =>
  foo <- bar
  foo -> bar
  2 <= 5
  5 >= 2
  2 == 2
  2 === 2l
  foo && bar
  foo || bar
  foo map bar
  foo flatMap bar

into

  foo ⇒
  foo ← bar
  foo → bar
  2 ≤ 5
  5 ≥ 2
  2 ≟ 2
  2 ≡ 2l
  foo ∧ bar
  foo ∨ bar
  foo ∘ bar
  foo ⤜ bar

Screenshot:

This does not – at any point – alter your source code. It simply uses Vim's "conceal" feature to “hide” map behind ∘, etc. Whenever the cursor is at a line with concealed text, the text will be expanded.

To install, simply put scala.vim in ~/.vim/after/syntax or use something like Pathogen (recommended).

Vim ≥ 7.3 is required.
