プロジェクトの歴史

The project started as ra-multiplex, focused on rust-analyzer. Its changelog shows early releases in January and February 2022 adding configuration, removing a nightly Rust requirement, improving client/server behavior, and adding initial support for language servers other than rust-analyzer.

In 2024, the project added status and reload commands, native LSP initialize-message handshakes, Unix socket support, and environment filtering. In October 2025, it migrated to Codeberg, changed license to EUPL-1.2, and was renamed from ra-multiplex to lspmux to reflect its broader language-server scope.

採用の歴史

lspmux is a niche developer tool aimed at users who run multiple editor windows or clients against the same workspace. The README points users to Cargo installation and package-manager availability through Repology, while the supplied package facts list Homebrew, Alpine, and Nix.

使われ方

The usual setup is to run `lspmux server` as a user service and configure an editor to use `lspmux` as the language-server executable or connect directly to the lspmux socket. The README gives examples for rust-analyzer, CoC in Neovim, clangd, systemd user services on Linux, and launchd services on macOS.

Configuration is optional and stored in a TOML file in the system default configuration directory, with `~/.config/lspmux/config.toml` given as the Unix example. The README documents defaults for instance timeout, garbage-collection interval, TCP or Unix-socket listen/connect addresses, logging filters, and environment-variable filtering.

パッケージ好きにとっての重要性

lspmux matters to package nerds because it is a resource-control tool for the LSP era. Rather than replacing an editor or a language server, it sits in the middle and makes repeated editor sessions cheaper, especially for heavy servers such as rust-analyzer.

タイムライン

• 2022: ra-multiplex 0.1.x releases add configuration and early support for non-rust-analyzer servers.
