A syntax file for Hy.

Requires a Vim built with Python support and Hy installed so that Vim can load it. You can verify this with

:python import hy

which should not show an error.

Use let g:hy_enable_conceal = 1 to enable support for concealing some constructs with unicode glyphs. If this option is enabled, this

(defn something [alpha beta]
  (sum (xi + x1 alpha) (range beta)))

will be displayed like this

(ƒ something [α β]
  (∑ (x¡ + x₁ α) (range β)))

The full table of concealed symbols looks like this:

If you do let g:hy_conceal_fancy=1, xi is displayed as ξ.
