A statusline / bufferline for Neovim written in Lua. It is inspired by vim-airline but aims to be as light and simple as possible.

Note: I won't add new features/parts/themes if I don't need them. Feel free to submit PRs or fork the plugin though.

Installation

With packer.nvim:

use {'ojroques/nvim-hardline'}

With paq-nvim:

paq {'ojroques/nvim-hardline'}

With lazy.nvim:

-- init.lua:
{'ojroques/nvim-hardline'},
-- plugins/hardline.lua:
return {
'ojroques/nvim-hardline',
}

Usage

In your init.lua:

require('hardline').setup {}

If you're using a .vimrc or init.vim:

lua require('hardline').setup {}

Configuration

You can pass options to the setup() function. Here are all available options with their default settings:

require('hardline').setup {
  bufferline = false,  -- disable bufferline
  bufferline_settings = {
    exclude_terminal = false,  -- don't show terminal buffers in bufferline
    show_index = false,        -- show buffer indexes (not the actual buffer numbers) in bufferline
  },
  theme = 'default',   -- change theme
  sections = {         -- define sections
    {class = 'mode', item = require('hardline.parts.mode').get_item},
    {class = 'high', item = require('hardline.parts.git').get_item, hide = 100},
    {class = 'med', item = require('hardline.parts.filename').get_item},
    '%<',
    {class = 'med', item = '%='},
    {class = 'low', item = require('hardline.parts.wordcount').get_item, hide = 100},
    {class = 'error', item = require('hardline.parts.lsp').get_error},
    {class = 'warning', item = require('hardline.parts.lsp').get_warning},
    {class = 'warning', item = require('hardline.parts.whitespace').get_item},
    {class = 'high', item = require('hardline.parts.filetype').get_item, hide = 60},
    {class = 'mode', item = require('hardline.parts.line').get_item},
  },
}

You can define your own sections using the sections list. Each element of that list is a table with the following attributes:

class: the section colorscheme. The following classes are currently available:
- mode: change color based on the current mode.
- low, med, high: colors for different levels of importance.
- bufferline: colors for the bufferline.
- error, warning: colors for the diagnostics of Neovim built-in LSP client.
item: the actual text being displayed. Must be a string or a function returning a string.
hide: threshold (in number of characters) below which the section will be hidden.
