Project history

The official README identifies LTeX+ LS as an implementation of the Language Server Protocol that checks markup documents with LanguageTool. It can run as an editor-facing language server or directly over file and directory paths as a command-line checker.

The project explicitly continues earlier work: its README says that until version 16.0.0 Julian Valentin developed the code as LTeX LS, and that LTeX LS itself was a fork of Adam Voss's abandoned languagetool-languageserver. The LTeX+ website similarly describes LTeX+ as a successor/fork of the abandoned LTeX extension and the earlier LanguageTool VS Code extension.

Adoption history

LTeX+ LS is the maintained successor in a lineage that already had editor adoption through LTeX and VS Code. Official GitHub signals show about 240 stars, 16 forks, 1,613 commits, and 13 releases, and the supplied package-manager facts show Homebrew and Nix packaging.

Release activity is current: GitHub lists 18.7.0 as the latest stable release on Jun 13, 2026 and an 18.7.1 alpha/nightly prerelease on Jun 23, 2026. That makes the `ltex-ls-plus` package the active branch of the LTeX language-server story after the original `ltex-ls` repository was archived.

How it is used

The official docs position LTeX+ as usable standalone from the command line, as an LSP server, or via editor extensions. The README says the reference client is the LTeX+ VS Code extension and that the language server can also print results to standard output without any language client.

Why package nerds care

Package nerds care about LTeX+ LS because it packages a heavyweight grammar engine into a language-server-shaped artifact with Java and LanguageTool bundled. That lets editors, CI scripts, and command-line workflows get offline grammar checking without separately managing LanguageTool or a JVM.

It is also a visible example of open-source succession: an abandoned VS Code grammar-checking extension led to LTeX, and LTeX's archival led to LTeX+, preserving package continuity for users who still expect `ltex-ls`-style binaries.
