LT_EX+ LS — LT_EX+ Language Server

LT_EX+ LS (LT_EX+ Language Server) implements a language server according to the Language Server Protocol (LSP) and provides grammar and spelling errors in markup documents (L^AT_EX, Markdown, etc.). The documents are checked with LanguageTool.

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

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

The reference language client of LT_EX+ LS is the LT_EX+ extension for Visual Studio Code (vscode-ltex-plus), whose development LT_EX+ LS follows closely and vice versa.

Until version 16.0.0, Julian Valentin developed LT_EX+ LS as LT_EX LS. LT_EX LS is a fork of the abandoned languagetool-languageserver by Adam Voss^†. This language server would not have been possible without the work of Adam Voss^† and Julian Valentin.
