de.setf.utility is a collection of Common Lisp utility functions and several purpose-specific libraries.

The extension libraries include

• stream and buffer serialization : de.setf.utility.codecs
  • Erlang Term Format serialization : de.setf.utility.codecs.etf
• date coding : de.setf.utility.date
• graphiz .dot graph generation : de.setf.utility.dot
• mime content types and simple utf coding : de.setf.utility.mime
• unit tests : de.setf.utility.test
  • an rspec interface : de.setf.utility.test.rspec
• code, image, package, system walkers : de.setf.utility.walker

The core library and all extensions are available from GitHub.

de.set.utility and its extensions are built with asdf. The core library can be built by adding its the utility.asd system definition file to the asdf registry and executing

(asdf:load-system :de.setf.utility)

The extension libraries require support for hierarchical system names in order to locate their prerequistes. The file build-init.lisp does the necessary to permit a build from the command-line. For example

$ cd $SOURCE_ROOT
$ sbcl --userinit build-init.lisp \
  --eval "(asdf:load-system :de.setf.utility.test.rspec)" \
  --eval '(cl-user::save-image "sbcl-rspec.core")'

This version is released under version 3 of the GNU Lesser General Public License (LGPL). The core library has no external dependencies. de.set.utility.walker depends on runtime-sepecific introspection extensions. de.setf.utility.tst.rspec depends on posix extensions for access to syslog.
