abcl-utils

Some utility functions to help in the day to day with ABCL Common Lisp

Maybe can be useful for someone else

I probably will add more if possible later ...

Quickstart

Clone this repository to your Quicklisp local-projects folder:

CL-USER> (ql:quickload :abcl-utils)

CL-USER> (in-package :abcl-utils)

ABCL-UTILS> (defmacro print-var (var)
              `(format t "~% ~a = ~s" ',var ,var))

PRINT-VAR

ABCL-UTILS> (let* ((utf8-bytes '(#xf0 #x9f #x91 #x8c))
                   (java-str-utf8 (bytes->unicode-java-string utf8-bytes "UTF8"))
                   (lisp-str-utf8 (bytes->unicode-lisp-string utf8-bytes "UTF8"))
                   (utf8-bytes-from-str (lisp-string->lisp-bytes lisp-str-utf8 "UTF8"))

                   (utf16-bytes (lisp-string->lisp-bytes lisp-str-utf8 "UTF16"))
                   (utf16-java-str (bytes->unicode-java-string utf16-bytes "UTF16"))

There is also abcl-utils:debug which can help to inspect variables contents in Slime/Sly
