Arxtect LaTeX WASM

English | 中文

Arxtect is a LaTeX compiler for VS Code powered by WebAssembly. It runs inside the editor, supports pdfTeX and XeTeX, and does not require a local TeX Live installation.

Install

Install Arxtect from the VS Code Marketplace, or run Extensions: Install from VSIX... to install a local .vsix package.
Requires VS Code 1.93.0 or later.
No local TeX Live installation is required. Internet access may be needed the first time Arxtect downloads TeX Live package files into its local cache.

Quick Start

Open a folder that contains your .tex project.
Open the main .tex file.
Run Arxtect: Compile LaTeX from the Command Palette, or press Ctrl+Alt+B (Cmd+Alt+B on macOS).
Open the generated PDF from the notification, the sidebar, or Arxtect: Open PDF.
For multi-file projects, run Arxtect: Set Main TeX File so Arxtect always compiles the correct entry file.

Features

Compilation

Compile .tex files directly in VS Code with WebAssembly.
Choose pdfTeX or XeTeX from commands, settings, or the sidebar.
Run multi-pass compilation for cross-references and labels.
Enable compile-on-save when you want automatic builds.
Configure compile timeout and auto-open PDF behavior.
Set a main TeX file for multi-file projects.

Language Tools
