Installation

Use luarocks or your favourite plugin manager.

Required

neovim >= 0.8
luasnip

Optional

haskell-language-server and haskell-tools.nvim (some snippets work better with LSP).
A Haskell tree-sitter parser or nvim-treesitter and the parser for haskell.

Quick setup

Add the following to your LuaSnip setup.

local ls = require('luasnip')
ls.setup {
  -- Add your LuaSnip config
}
local haskell_snippets = require('haskell-snippets').all
ls.add_snippets('haskell', haskell_snippets, { key = 'haskell' })
