Osicat is lightweight operating system interface for Common Lisp on POSIX-like systems, licensed under a MIT-style license.
Osicat uses UFFI for foreign bindings, so it is relatively portable, though most active development happens on SBCL and Debian GNU/Linux, so other platforms may experience wrinkles.
Features
- directory iteration and deletion
- environment variables
- symbolic links
- file permissions
- file-type identification
Installation
If you have asdf-install, just:
$ asdf-install osicat
Osicat can manually be downloaded from here: osicat_latest.tar.gz .
There is also anonymous CVS and ViewCVS .
