This project aims to provide a beginner-friendly REPL for Common Lisp with rich functionalities, such as IPython for Python.

What this project tries to achieve are listed here.

• powerful multiline editing with gnu readline.
• saving and loading multiline history.
• tab-completion of symbols.
• simple installation instruction.
• code editting with text editor.
• useful debugger & inspector. (incomplete)
• syntax highlighting of input texts.
• paren-matching.
• implementation independence: builds on SBCL and CCL. Segfaults on ECL.
• autoindentation

Look up the latest release compatible with your OS under https://github.com/lisp-maintainers/cl-repl/releases.

If your choice of OS is not listed, you can help make lisping easier for others by contributing a PR. Take a look at the .github/workflows/CI.yml for an inspiration. If it's unix-based, it might be as simple as adding a name to matrix -> OS.

CL-REPL can be installed via roswell as follows.

$ ros install lisp-maintainers/cl-repl

Before installation, please ensure that gnu readline is installed. If you use OSX, you might need to execute following command.

$ brew link --force readline

Also, ensure that your terminal support 256 colors.

If you installed roswell with normal configurations, cl-repl will be located in ~/.roswell/bin.   To use cl-repl from the command line, please ensure the PATH variable includes ~/.roswell/bin.

Some useful magic commands are ready to use. To list available commands:

You can customize CL-REPL by editting ~/.replrc. You can change appearance, add your own commands, and do anything you want when startup. An example can be found here.

Syntax highlighiting of input area is new in v0.5.0. If you want to disable it, put the following in your .replrc.

If the line starts with !, excute it as shell command, e.g. !ls -a.

Line editting in repl is sometimes painful. CL-REPL allows yot to edit code with your favorite text editor.

CL-REPL> %edit <filename>

CL-REPL invokes a text editor specified by $EDITOR. After editting code, save and close it. Then repl will start to evaluate it. If <filename> is not supplied, a temporary file will be created and deleted after evaluation.

We've be sure the following editors work properly.

• vi & vim
• GNU Emacs
• joe's own editor
• Lem

Don't hesitate to open issues or to send PRs. Any suggestions are always welcomed.

• (Complexity: high) Support for menu based completion: can we have an ipython-like dropdown menu based completion?
• (Complexity: moderate) MacOS Binaries through Github Actions
• (Complexity: moderate) Linux Arm64 binaries through Travis or something else
• (Complexity: moderate) Windows Binaries
• (Complexity: moderate) Automating tests
• (Complexity: moderate) Add support for logs
