## Quick Links

- [Quick Setup](#quick-setup)

- [Snippets](#snippets)

- [Recommendations](#recommendations)

- [Contributing](./CONTRIBUTING.md)

## Installation

Use luarocks or your favourite plugin manager.

### Required

- `neovim >= 0.8`

- [`luasnip`](https://github.com/L3MON4D3/LuaSnip)

### Optional

- [`haskell-language-server`](https://haskell-language-server.readthedocs.io/en/latest/installation.html)

  and [`haskell-tools.nvim`](https://github.com/mrcjkb/haskell-tools.nvim)

  (some snippets work better with LSP).

- A Haskell tree-sitter parser or

  [`nvim-treesitter`](https://github.com/nvim-treesitter/nvim-treesitter)

  and the parser for haskell.

## Quick setup

Add the following to your LuaSnip setup.

```lua

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' })

```

## Snippets

> [!NOTE]

>

> - The recording software [ttyrec](https://github.com/mjording/ttyrec)

>   sometimes has some visual glitches.

> - Many snippets provided by this plugin use [choice nodes](https://github.com/L3MON4D3/LuaSnip/blob/master/DOC.md#choicenode)

## Recommendations

Here are some other plugins I recommend for Haskell development:

- [mrcjkb/haskell-tools.nvim](https://github.com/mrcjkb/haskell-tools.nvim):

  Toolset to improve the Haskell experience in Neovim.

- [neotest-haskell](https://github.com/MrcJkb/neotest-haskell):

  Interact with tests in neovim.

- [luc-tielen/telescope_hoogle](https://github.com/luc-tielen/telescope_hoogle):

  Hoogle search.
