Common Lisp commands

Start a Lisp REPL with M-x start-lisp-repl.

To switch to the Lisp REPL: C-c C-z. You can use quick commands inside the REPL. They start with a , (coma).

To compile and load a buffer: C-c C-k. To compile a function: C-c C-c.

To evaluate some Lisp code: M-:.

Lem features an advanced interactive debugger. You can navigate and inspect the stacktraces (C-n, C-p), go to the error’s origin (v on the backtrace), restart a given point of the backtrace (r, sldb-restart-frame), and so on. Quit the debugger with q, or use a suggested restart (by entering its number, pressing Enter on it, or clicking on it).

Try one of these two commands:

• hyperspec-at-point opens a browser to the HyperSpec page for the Lisp symbol the point is on,
• hyperspec-lookup lets you choose a symbol (with auto-completion).

These commands were added after Lem 2.0.
