A cross-platform implementation of the Language Server Protocol providing rich cross-editing support for the LaTeX typesetting system. The server may be used with any editor that implements the Language Server Protocol.


Getting Started

If your editor extension like does not install the TexLab server automatically, you will need to install it manually. We provide precompiled binaries for Windows, Linux and macOS. Alternatively, you can build TexLab from source or install it using your package manager. For a list of supported package managers, you can take a look at Repology.


A TeX distribution is not strictly required to use the server but TexLab cannot compile your documents without one. TexLab supports compiling using Tectonic. For an example configuration, please see here.

On Windows, you may need to install Microsoft Visual C++ Redistributable for Visual Studio 2015.

Building from Source

You will need to install the following dependencies to compile the server:

  • A recent, stable version of Rust (>= 1.51)

Then run the following command in the project folder:

cargo build --release

Alternatively, you can run the following command without having to clone this repository and make TexLab available in your PATH:

cargo install --git --locked


After installing an editor extension, you can simply start editing LaTeX files. All editing features work out-of-the-box over all files in the currently opened workspace. There is no need for magic comments like %!TEX root and TexLab should figure out the dependencies of a file on its own. Note that you may need to set the texlab.rootDirectory option for some multi-folder projects.

TexLab features a variety of options which can be used to configure features like building or forward search.


You can create a debug build by building the server without the --release flag. The resulting build can be used with the Visual Studio Code extension by adding the absolute path of the target/debug folder to your PATH environment variable.

TexLab has an extensive test suite of unit and integration tests. You can run them by executing

cargo test

in the project folder.
