Features

  • Alignment is done in three main steps:
    • Split lines into parts based on Lua pattern(s) or user-supplied rule.
    • Justify parts for certain side(s) to be same width inside columns.
    • Merge parts to be lines, with customizable delimiter(s).
    Each main step can be preceded by other steps (pre-steps) to achieve highly customizable outcome. See steps value in :h MiniAlign.config. For more details, see :h MiniAlign-glossary and :h MiniAlign-algorithm.
  • User can control alignment interactively by pressing customizable modifiers (single keys representing how alignment steps and/or options should change). Some of default modifiers:
    • Press s to enter split Lua pattern.
    • Press j to choose justification side from available ones (“left”, “center”, “right”, “none”).
    • Press m to enter merge delimiter.
    • Press f to enter filter Lua expression to configure which parts will be affected (like “align only first column”).
    • Press i to ignore some commonly unwanted split matches.
    • Press p to pair neighboring parts so they be aligned together.
    • Press t to trim whitespace from parts.
    • Press <BS> (backspace) to delete some last pre-step.
    For more details, see :h MiniAlign-modifiers-builtin and :h MiniAlign-examples.
  • Alignment can be done with instant preview (result is updated after each modifier) or without it (result is shown and accepted after non-default split pattern is set).
  • Every user interaction is accompanied with helper status message showing relevant information about current alignment process.

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):

With mini.deps
  • ‘mini.nvim’ library:

    Branch Code snippet
    Main Follow recommended ‘mini.deps’ installation
    Stable Follow recommended ‘mini.deps’ installation
  • Standalone plugin:

    Branch Code snippet
    Main add(‘nvim-mini/mini.align’)
    Stable add({ source = ‘nvim-mini/mini.align’, checkout = ‘stable’ })
With folke/lazy.nvim
  • ‘mini.nvim’ library:

    Branch Code snippet
    Main { 'nvim-mini/mini.nvim', version = false },
    Stable { 'nvim-mini/mini.nvim', version = '*' },
  • Standalone plugin:

    Branch Code snippet
    Main { 'nvim-mini/mini.align', version = false },
    Stable { 'nvim-mini/mini.align', version = '*' },
With junegunn/vim-plug
  • ‘mini.nvim’ library:

    Branch Code snippet
    Main Plug 'nvim-mini/mini.nvim'
    Stable Plug 'nvim-mini/mini.nvim', { 'branch': 'stable' }
  • Standalone plugin:

    Branch Code snippet
    Main Plug 'nvim-mini/mini.align'
    Stable Plug 'nvim-mini/mini.align', { 'branch': 'stable' }

Important: don’t forget to call require('mini.align').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.
