==============================================================================

Features:
- Highlighting is done only in modifiable buffer by default, only in Normal
  mode, and stops in Insert mode and when leaving window.

- Trim all trailing whitespace with |MiniTrailspace.trim()|.

- Trim all trailing empty lines with |MiniTrailspace.trim_last_lines()|.

# Setup ~

This module needs a setup with `require('mini.trailspace').setup({})`
(replace `{}` with your `config` table). It will create global Lua table
`MiniTrailspace` which you can use for scripting or manually (with
`:lua MiniTrailspace.*`).

See |MiniTrailspace.config| for `config` structure and default values.

You can override runtime config settings locally to buffer inside
`vim.b.minitrailspace_config` which should have same structure as
`MiniTrailspace.config`. See |mini.nvim-buffer-local-config| for more details.

# Highlight groups ~

* `MiniTrailspace` - highlight group for trailing space.

To change any highlight group, modify it directly with |:highlight|.

# Disabling ~

To disable, set `vim.g.minitrailspace_disable` (globally) or
`vim.b.minitrailspace_disable` (for a buffer) to `true`. Considering high
number of different scenarios and customization intentions, writing exact
rules for disabling module's functionality is left to user. See
|mini.nvim-disabling-recipes| for common recipes. Note: after disabling
there might be highlighting left; it will be removed after next
highlighting update (see |events| and `MiniTrailspace` |augroup|).
