# LTEX+ LS — LTEX+ Language Server

LTEX+ LS (LTEX+ Language Server) implements a language server according to the [Language Server Protocol (LSP)](https://microsoft.github.io/language-server-protocol/) and provides grammar and spelling errors in markup documents (LATEX, Markdown, etc.). The documents are checked with [LanguageTool](https://languagetool.org/).

Typically, you start the language server (either locally or remotely), you send the language server your LATEX or Markdown document, and it will respond with a list of the grammar and spelling errors in it. To use LTEX+ LS in this way, you have to use a language client (usually an editor or an extension of the editor) that communicates with LTEX+ LS according to the LSP.

However, it is also possible to supply LTEX+ LS paths to files and directories to be checked as command-line arguments. In this mode, LTEX+ LS will print the results to standard output, and no language client is necessary.

The reference language client of LTEX+ LS is the [LTEX+ extension for Visual Studio Code (vscode-ltex-plus)](https://ltex-plus.github.io/ltex-plus/), whose development LTEX+ LS follows closely and vice versa.

Find more information (how to install, how to use, etc.) at the [website of LTEX](https://ltex-plus.github.io/ltex-plus/).

Until version 16.0.0, Julian Valentin developed LTEX+ LS as [LTEX LS](https://github.com/valentjn/ltex-ls). 

LTEX LS is a fork of the abandoned [languagetool-languageserver](https://github.com/adamvoss/languagetool-languageserver) by Adam Voss†.

This language server would not have been possible without the work of Adam Voss† and Julian Valentin.
