cl-fu

CL-FU is a Common Lisp CFFI library for NCURSES.

Package :fu exports ncurses bindings with the usual C-to-Lisp mapping (underscores turn to dashes, etc).

The goal of the project is to provide a reasonably complete interface to NCURSES.

Status

06-Nov-2017 - Implementation complete - testing.

Notes

• printw functions use a c-style format string, but require cffi types for parameters. (printf "Hello number %d" :int 3)
• \n and other escapes do not seem to work (priority med)

Not Implemented

While the goal is a reasonably complete implementation, a decision was made to not bother with:

• Input functions without a count - such as getstr. Use getnstr, etc.
• Scan functions - not particularly useful...(priority low)
• va_list versions of functions (priority low)

Quick start

NCURSES is a console library and requires a real terminal. If you develop with Slime, start a separate Swank session in a terminal, from the command line, with something like: SBCL:sbcl --eval "(ql:quickload '(:swank) :silent t)" --eval "(swank:create-server :port 4006 :dont-close t :style :fd-handler)" Roswell: ros run -e "(ql:quickload '(:swank) :silent t)" -e "(swank:create-server :port 4006 :dont-close t)" Connect to it from emacs with slime-connect, entering the same port (4006 in this case).

Test with something like:

(initscr)
(printw "hello")
(refresh)
(getch)
(endwin)

Project goals:

• access to entire library
• clean low level

• cl-ncurses (old, no cffi)
• cl-charms (incomplete, unhappy with some choices made)
