texsh

A LaTeX math shell for the terminal. Type an expression, press Enter, and it renders in place — shell flow like zsh or bash, math layout from opentui-math.

texsh> x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}

           ╭────────
     -b ± √ b² - 4ac
x = ─────────────────
           2a

texsh> \int_{-\infty}^{\infty} e^{-x^2}\,dx = \sqrt{\pi}

 ∞   -x²      ╭─
∫   e   dx = √ π
 -∞

On Kitty-compatible terminals (Ghostty, Kitty, WezTerm) formulas also render as high-resolution MathJax graphics, with automatic Unicode-cell fallback everywhere else.

• Bun ≥ 1.3
• A real terminal (not a bare pipe)

bun install
bun start

Or:

bun index.ts

Common delimiters are stripped automatically, so pasting $E=mc^2$, $$...$$, \(...\), or \[...\] works.

• @opentui/core — terminal UI (prompt, scroll history, input)
• opentui-math — LaTeX → Unicode cells / Kitty graphics
