Installation

This plugin can be installed as part of 'mini.nvim' library (recommended) or as a standalone Git repository.

There are two branches to install from:

• main (default, recommended) will have latest development version of plugin. All changes since last stable release should be perceived as being in beta testing phase (meaning they already passed alpha-testing and are moderately settled).
• stable will be updated only upon releases with code tested during public beta-testing phase in main branch.

Here are code snippets for some common installation methods (use only one):

Important: don't forget to call require('mini.trailspace').setup() to enable its functionality.

Note: if you are on Windows, there might be problems with too long file paths (like error: unable to create file <some file name>: Filename too long). Try doing one of the following:

• Enable corresponding git global config value: git config --system core.longpaths true. Then try to reinstall.
• Install plugin in other place with shorter path.

Default config

-- No need to copy this inside `setup()`. Will be used automatically.
{
  -- Highlight only in normal buffers (ones with empty 'buftype'). This is
  -- useful to not show trailing whitespace where it usually doesn't matter.
  only_in_normal_buffers = true,
}
