ZedTeX adds LaTeX previews and notebook exports to Zed, with support for real TeX packages.

File	Result
.tex	PDF and page previews inside Zed
.md	A Markdown preview with rendered equations
.ipynb / Python notebook	HTML or PDF with freshly executed outputs

Install

Registry submission pending. For now, clone this repository and select it through Zed’s Install Dev Extension. Dev setup and updates →

Once published, install ZedTeX from the Extensions UI. The renderer downloads automatically. Also install LaTeX for .tex language support.

Preview and export

Open a saved source file, press Ctrl+Shift+P (Cmd+Shift+P on macOS), and run editor: toggle code actions.

• TeX: choose LaTeX: build and open preview. The first page opens in Zed’s image viewer.
• Markdown: choose the same action, then press Ctrl+Shift+V (Cmd+Shift+V on macOS) in the generated preview.md tab.
• Notebooks: choose Notebook: run all cells and export to HTML or PDF. The notebook’s Jupyter kernel and dependencies must be installed on the machine running the renderer.

Keep editing the original file; saving updates an activated preview. Unchanged equations are reused, and notebook exports run separately so previews stay responsive. Generated files stay in the user cache, outside your repository—save a copy of exports you want to keep.

Markdown math appears in the generated preview. Zed’s original Markdown preview is unchanged. For live Jupyter equations, see the rendering helper.

LaTeX packages

TeX documents use their own preambles. For Markdown and notebooks, place latex-preamble.tex beside the source:

\usepackage{amsmath,amssymb,mathtools}
\boldmath
% \usepackage{localmath} % optional local .sty file

The preamble configures packages; preview the document, not the preamble itself.
