vim-hy

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.

Installation

If you are using Plug, add this to your plugins list in .vimrc:

Plug 'hylang/vim-hy'

Otherwise, install using whatever vim plugin approach you prefer.

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:

Symbol	Display	Symbol	Display	Symbol	Display
`fn`	`λ`	`and`	`∧`	`<=`	`≤`
`lambda`	`λ`	`or`	`∨`	`>=`	`≥`
`defn`	`ƒ`	`not`	`¬`	`!=`	`≠`
`defn/a`	`ƒa`	`fn/a`	`λa`	`lfor`	`s∀`
`sfor`	`s∀`	`dfor`	`d∀`	`gfor`	`g∀`
`*`	`∙`	`->`	`⊳`	`None`	`∅`
`math.sqrt`	`√`	`->>`	`‣`	`math.pi`	`π`
`sum`	`∑`	`for`	`∀`	`some`	`∃`
`in`	`∈`	`alpha`	`α`	`gamma`	`γ`
`not-in`	`∉`	`beta`	`β`	`delta`	`δ`
`epsilon`	`ε`	`xi`	`x¡`	`#%`	`x¡`
`x[0-9]`	`x₀` - `x₉`

If you do let g:hy_conceal_fancy=1, xi and #% are displayed as ξ.
