Announcing Clon, the Common Lisp / Command-Line Options Nuker

I’m happy to announce the first public release of Clon , the Common Lisp / Command-Line Options Nuker, the Common Lisp / Command-Line Options Nuker library for Common Lisp.

Clon is a library for managing command-line options in standalone Common Lisp applications. It provides a unified option syntax with both short and long names, automatic completion of partial names and automatic retrieval/conversion of option arguments from the command-line, associated environment variables, fallback or default values. Clon comes with a set of extensible option types (switches, paths, strings etc.). Clon also provides automatic generation and formatting of help strings, with support for highlighting on TTYs through ISO/IEC 6429 SGR. This formatting is customizable through “themes”.

Clon currently requires SBCL to work. If you want to help porting it to other implementations, please grep PORTME in the sources.
