Development, building, testing, and documentation aids.

Editor/IDE support

    • SLIME is the Superior Lisp Interaction Mode, Extended
    • PORTACLE is a portable and multiplatform development environment, pre-configured with SBCL, Quicklisp, Emacs, Slime and Git. Download, extract and use, no installation needed.
  • vi/vim
    • Slimv provides SLIME-like Lisp and Clojure REPL inside Vim with profiling, Hyperspec lookup, Paredit-like structured editing
    • Nekthuth is a vim plugin and CL library which gives vim users some interactive Lisp development/IDE features akin to SLIME
    • VIlisp, an (inferior) inferior lisp mode for vim.
    • Limp, another (slightly less inferior) inferior lisp mode for Vim.
    • Using vi with Lisp
  • Atom
    • atom-slime is an Atom plugin for Common Lisp development.
  • Eclipse
    • Cusp An Eclipse plugin that comes out of the box with SBCL and Swank for Windows, Linux, and OSX
    • Dandelion Another Eclipse plugin, currently available with CLISP (for WinXP, MacosX, Linux). It supports the developer with syntax analyses as you type (limited), syntax highlighting, code completion, parenthesis matching, apropos and a listener.
    • lispdev is a fork of Cusp
  • Other
    • MCLIDE is an open source Mac OS X IDE for Lisp implementations using the SWANK protocol of SLIME. It supports Common Lisp, Clojure, and Scheme.
    • Climacs is an Emacs-like text editor written in Common Lisp using McCLIM.
    • Hemlock is an Emacs-like editor written in CL not using CLIM.
    • Able a IDE written in CL itself, for Mac/Windows/Linux, also with interaction mode.
    • LispIDE is a basic editor for several Lisp and Scheme implementations available for Windows.
    • Clcon is a cross-platform Lisp IDE with permissive license. It uses SWANK protocol of SLIME to connect to server. Under construction, no releases yet.
