RTL Math Text

RTL Math Text

RTL Math Text is a plugin for Obsidian that adds basic support for mixing right-to-left (RTL) and left-to-right (LTR) text in MathJax expressions through the use of custom LaTeX commands.

Features

• Add strictly right-to-left (RTL) text (e.g. Hebrew) inside math expressions using \R{\text{...}}
• Nest strictly left-to-right (LTR) text (e.g. English) inside RTL using \L{...}
• Nest math (e.g. numbers) inside RTL/LTR using $...$ in display mode or using \(...\)
• Configure the names of the \R{...} and \L{...} commands in the settings

⚠ Note: The plugin does not add support for languages with combining letters (e.g. Arabic). This is expected to be resolved with the upcoming release of MathJax 4.0 (see mathjax/MathJax#3041).
