CL-ROGUE

This is a nearly line-for-line port of Rogue v3.6.2 from C to Common Lisp. The goal of this exercise was to see how easy it would be to write idiomatic 1980s-era C, well-written but with lots of side-effects and stuff, in Common Lisp. In the process of porting the code, I gained an appreciation for the pragmatic elegance of the Rogue code base. It also showed me that it was possible to keep the code almost exactly the same across both languages (same variable names, same control flow), with only a few exceptions.

The source code is most likely here; see also version 5.4.4.

Dependencies

SBCL

Only SBCL has been tested. No external Common Lisp libraries are required — terminal I/O is handled by a pure-CL VT100 implementation (terminal.lisp) that replaces the original ncurses dependency.

Running

Locally

Build the binary once with the provided script:

sbcl --load load.lisp

This produces a standalone cl-rogue binary. Then run it in any screen-oriented terminal:

./cl-rogue

Alternatively, load and run directly from SBCL without building:

(pushnew (merge-pathnames "src/cl-rogue/" (user-homedir-pathname)) asdf:*central-registry*)
(asdf:load-system :cl-rogue)
(cl-rogue:rogue)

Note: substitute the actual path to the repository for "src/cl-rogue/".

Using Docker

Using the Dockerfile in the cl-rogue directory, you should be able to do the following:

cd cl-rogue
docker build -t cl-rogue .
docker run -i -t cl-rogue

Headless driver (Python)

The driver/ directory contains a Python headless driver that runs cl-rogue in a PTY (no real terminal required) and lets you send keystrokes and inspect the screen programmatically — useful for scripted play and bug-finding:

cd driver
python3 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
python example.py
