This syntax file displays unicode characters for some Python operators and built-in functions, turning the following:
map (lambda x: x, [1,2,3]) def foo(e, a): if e in [1,2,3] and not a: return math.sqrt(math.pi) else: return sum([1,2,3])
map (λ x: x, [1,2,3]) def foo(e, a): if e ∈ [1,2,3] ∧ ¬a: return √(π) else: return ∑([1,2,3])
This does not – at any point – alter your source code. It simply uses Vim's
"conceal" feature to “hide”
∈, etc. Whenever the cursor is at
a line with concealed text, the text will be expanded.
To install, simply put
~/.vim/after/syntax or use something
like Pathogen (recommended).
Vim ≥ 7.3 is required.
moresymbols includes commits from various people that add even more
conceal replacements. I try to maintain a healthy balance in the
branch, but if you like to conceal even more operators or don't mind slight
inaccuracies in what mathematical symbols are used to represent, you should have
a look at the extra symbols in the
