A Lisp REPL in your pocket
Thanks to Polos Ruetz, you can now play with Common Lisp directly on your Android phone. All you need to do is install CL REPL from the Google Play Store. CL REPL is one of the examples part of EQL5-Android which is built on top of EQL5, a project that marries ECL with Qt.
CL REPL
A Common Lisp REPL with command line and history, plus a simple editor with syntax highlighting, simple visual paren-matching, a file dialog for opening/saving files, and a simple debug dialog. It uses the ECL implementation for the Lisp side, and Qt5/QML for the UI. This is an open source project (see EQL5-Android).
