nvim-anydent is a Neovim plugin that provides automatic indentation based on simple heuristics.

vim.api.nvim_create_autocmd('FileType', {
  callback = function()
    if not vim.tbl_contains({ 'html', 'yaml', 'markdown'  }, vim.bo.filetype) then
      require('anydent').attach()
    end
  end
})

nvim-anydent determines indentation based on:

• Indent Patterns: If a line matches a predefined pattern indicating an increase in indentation (e.g., ending with { in C-style languages), the next line will be indented.
• Dedent Patterns: If a line matches a pattern signaling a decrease in indentation (e.g., starting with }), that line will be dedented.
• Manual Patterns: Customizable rules to handle special cases like doc comments.
• Indentkeys: A list of words that trigger automatic indentation when typed at the end of a line.

Based on the author's past experience, this approach worked correctly in most cases for languages with C-style syntax.

• nvim-anydent does not attempt to be a full-fledged indentation engine.
• It may not handle deeply nested or highly structured languages perfectly.
• It prioritizes consistency over strict correctness.

If you need a 100% accurate indentation system, language-specific tools or Treesitter-based solutions may be better suited. However, if you prefer an always-reasonable indentation solution, nvim-anydent is for you.
