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.

Here are some key features of "Osicat":

· 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")
(USER-READ USER-WRITE
USER-EXEC
