sbcli

sbcli enters an interactive debugger with restarts when errors occur, allowing developers to handle crashes without terminating the session, as detailed in the debugger command table and usage section.

With cl-readline integration, it supports multiline input, tab completion, and command history, making REPL editing smoother than the default SBCL REPL, as noted in the usage overview.

Provides quick access to documentation, disassembly, and type inspection via commands like :doc, :d, and :t, facilitating code exploration and debugging directly in the REPL.

Features like environment reset with :r, history saving with :s, and customizable prompts via .sbclirc file offer flexible workflow control, with exposed variables listed in the README.
