License: MIT Test Status

Incline is a plugin for creating lightweight floating statuslines. It works great with Neovim's global statusline (:set laststatus=3).

Why use Incline instead of Neovim's built-in winbar? Incline:

  • Only takes up the amount of space it needs, leaving more room for your code.
  • Is highly configurable and themeable using Lua.
  • Can be shown/hidden dynamically based on cursor position, focus, buffer type, or any other condition.
  • Can be positioned at the top or bottom, left or right side of each window.

Configuration

The render function is the most important part of an Incline configuration. As the name suggests, it's called for each window in order to render its statusline. You can think of it like a React component: it's passed a table of props and returns a tree-like data structure describing the content and appearance of the statusline. For example:

render = function(props)
  local filename = vim.fn.fnamemodify(vim.api.nvim_buf_get_name(props.buf), ':t')
  local modified = vim.bo[props.buf].modified
  return {
    ' ',
    filename,
    modified and { ' *', guifg = '#888888', gui = 'bold' } or '',
    ' ',
    guibg = '#111111',
    guifg = '#eeeeee',
  }
end

The returned value can be nil, a string, or a table which can include strings, highlight properties like foreground/background color, or even nested tables. Nested tables can contain the same sorts of things, including more nested tables. If the render function returns nil, the statusline will be hidden until the next time the render function returns a non-nil value. For more on the render function, see :help incline-render.

Below are some examples to get you started.
