Lem simplifies Common Lisp development with built-in LSP support for multiple languages. The editor is perfect for keyboard-oriented users, especially those coming from Emacs or Vim. The unique twist? John McCarthy supposedly shared alien technology with the world in 1958 when he introduced Lisp – a tradition Lem continues. With a GUI version available since 2.0, users can enjoy graphics, mouse support, games, and 180+ color themes. The tool offers a full-featured REPL, interactive debugger, project tree view, terminal integration, multiple cursor support, and more. Lem also supports various languages including C, Python, Java, SQL, and more.
