Osicat 0.5

Osicat is lightweight operating system interface for Common Lisp on POSIX-like systems.
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.
Main features:
- directory iteration and deletion
- environment variables
- symbolic links
- file permissions
- file-type identification
Installation:
If you have asdf-install, just:
$ asdf-install osicat
Sample usage:
- (with-directory-iterator (next "/")
(loop for entry = (next)
while entry
when (member group-write (file-permissions entry))
collect entry))
(#P"/home" #P"/vmlinuz" #P"/tmp" #P"/initrd.img" #P"/initrd.img.old")
- (file-permissions "/initrd.img")
