LaTeX Package: BabelBidi v0.4.1 2026-10-26

An extension to babel’s bidirectional support

Description

babelbidi extends Babel's bidirectional support with direction-sensitive fixes, explicit direction and language selection, and font configuration with LuaTeX glyph fallback. It supports Babel languages, LTR and RTL main languages, and LuaTeX (recommended), XeTeX, or pdfTeX.

Features

• Explicit text-direction control.
• Language-aware inline text and block environments.
• Automatic selection of auxiliary Babel languages.
• Font configuration, including LuaTeX glyph fallback.
• Layout patches for direction-sensitive elements and common packages.

Installation

From CTAN

Latest release: https://ctan.org/pkg/babelbidi

~bash tlmgr install babelbidi ~

Manual installation from GitHub

~bash git clone https://github.com/gambi-shah/babelbidi.git ~

Copy the files into a TeX-searchable directory (run mktexlsr if needed) or keep them beside your document.

Usage

~latex documentclass{article} usepackage{babelbidi}

begin{document} Hey world! end{document} ~

Compile with LuaLaTeX (recommended), XeLaTeX (fallback), or pdfTeX (last resort). Babel language options are supported; see the Babel manual for the complete list.

Interfaces

• \LRE{...} and \RLE{...} — typeset text with explicit direction.
• \lr{...} and \rl{...} — switch to the configured LTR and RTL languages for inline text.
• LTR, RTL, and latin environments — typeset longer text blocks.
• \latinverb, \latinverb*, latinverbatim, and latinverbatim* — use the code language and its monospaced font for every main script; starred forms show spaces. Base interfaces retain their behaviour.
• \settextfont, \setlatintextfont, \setlatinsansfont, \setlatinmonofont, and \deflatinfont — configure fonts with Unicode engines.
• \fontfallback — configure font fallback with LuaLaTeX.

Code layout patches apply to non-Latin main scripts. Related packages can be loaded before or after babelbidi.

Language selection

Auxiliary languages (Latin, LTR, RTL, and code) are selected automatically and updated after each \babelprovide call. The latin, ltr, rtl, and code options fix these choices explicitly. Declare languages before setting fonts. Babel's nil is ignored; without a real language, Latin, LTR, and code default to english, and RTL to arabic.
