RenderPaper

Render and edit Markdown and LaTeX files in VS Code and compatible editors. The original .md or .tex file remains the source document.

Features

• Preview .md and .tex files.
• Click a rendered block to edit its source.
• Edit table cells with one click; edit the full table with a double-click.
• Update the preview while typing.
• Render only the visible parts of long documents.
• Refresh local images when image files change.
• Follow links between Markdown and LaTeX documents.
• Configure fonts, table alignment and project styles.
• Send selected source to the Agent panel in Antigravity. In VS Code, the same Markdown context is copied to the clipboard for manual paste.

Install

1. Open the Extensions view in VS Code or Antigravity.
2. Choose Install from VSIX.
3. Select the RenderPaper VSIX file.
4. Run Developer: Reload Window after updating the extension.

Open a preview

Enable RenderPaper: Override Default Preview to use RenderPaper from:

• Open Preview to the Side;
• the editor and Explorer context menus;
• Ctrl+K V.

Enable RenderPaper: Open Preview Automatically if previews should open with Markdown and LaTeX files.

Editing

• Click a rendered paragraph, heading, formula or other block to edit it.
• Click a table cell to edit only that cell.
• Double-click a table to edit the full table source.
• Click outside the editor to finish editing.
• Use the right-click menu for Cut, Copy and Paste.

Unsupported or incomplete syntax is shown as source text instead of an error page.

Markdown support

RenderPaper supports common Markdown, KaTeX formulas, tables, reference links, footnotes, local images and <br> line breaks.

Local links can open Markdown and LaTeX files:

[Markdown chapter](https://github.com/mxoxwh/RenderPaper/blob/HEAD/chapters/results.md#measurements)
[TeX appendix](https://github.com/mxoxwh/RenderPaper/blob/HEAD/appendix/derivation.tex#eq:main)

LaTeX Lite support

The built-in LaTeX renderer supports:

• titles, abstracts and sections;
• text styles and links;
• formulas and common math environments;
• labels and references;
• figures, local images and captions;
• basic tables, lists, quotes, theorem/proof and code environments.

It does not run TeX, shell commands or produce PDF files. Unsupported commands remain visible and editable as source.

Table-cell editing supports tabular, tabularx, tabular* and longtable, including the first supported table inside a table or table* environment.
