pointfree.nvim

Convert Haskell code into point-free Haskell code, within Neovim!

This plugin lets you use the pointfree tool inside the editor, transforming the current line, or with a visual selection.

Installation

Requirements:

• pointfree package (e.g. stack install pointfree)
• plenary.nvim plugin

Then, add this plugin using your favourite Neovim package manager:

use({
  "farbodsz/pointfree.nvim",
  requires = "nvim-lua/plenary.nvim",
  ft = "haskell"
})

Usage

• Run :Pointfree to replace your current line with the pointfree version
• In visual mode, use :PointfreeSelection to replace your selection with the pointfree version

About

Motivation

Haskell programmers often write in pointfree style, which is considered cleaner. The existing tools for transforming a function definition into pointfree style are wonderful, but it would be even better if these were integrated into the text-editing experience.

Credits

• bmillwood/pointfree for the standalone version of the Haskell point-free tool
• keathley/pointfree.io for the web version of this tool, which I have used countless times

There are a couple similar Vim plugins which I was unaware of when developing this one. These work slightly differently to this plugin:

• m00qek/vim-pointfree
