bidi.nvim

A Neovim plugin to support bidirectional text (mixing Left-to-Right and Right-to-Left).

Note

Currently, this plugin only supports Hebrew.

Features

• Bidirectional Display: Automatically reverses Hebrew text in standard mode (set norightleft) so it reads correctly.
• Right-to-Left Mode Support: Automatically reverses Latin text in set rightleft mode so it reads correctly.
• Toggle Support: Reacts to set rightleft / set norightleft changes dynamically.
• Granular Control: Enable or disable bidi rendering globally or per-buffer.

Installation

Using lazy.nvim:

-- Simple installation
{
  "yairh/bidi.nvim",
  -- To activate only when opening a buffer (lazy loading):
  event = { "BufReadPost", "BufNewFile" },
  config = function()
    require("bidi").setup()
  end,
}

Since lazy.nvim handles lazy loading, you can use event or cmd to control when the plugin (and its bidi rendering) activates.

Usage

Commands

• :Bidi enable: Enable bidi rendering globally.
• :Bidi disable: Disable bidi rendering globally (clears all bidi marks).
• :Bidi buf_enable: Enable bidi rendering for the current buffer only (overrides global disable).
• :Bidi buf_disable: Disable bidi rendering for the current buffer only (overrides global enable).

Settings

You can toggle set rightleft in Neovim to switch the base direction of the window, and the plugin will adjust the rendering accordingly.
