os_sub

collect files and sub-directories

This is a versatile library for looking into the contents of file systems.
The main scenario is that of finding all the directories and files within a single directory.
There is a large number of options that can control the behaviour of the library predicates.

highlights

• can be asked to return only files or directories, mix them or return both in separate lists
• symbolic links to files can be further separated or ignored
• replies with objects or os_obj(Obj,Type,Depth) terms
• depth limit and depth selection
• allows OS objects to be returned as 'ab/cde/f' (default) or ab/cde/f
• can use block lists
• error handling of options (semi-conforming to Swi option handling).

This library has been developed and (only) tested on linux systems. It should work on other OSes as well.

installation

It is highly recommended that you install from within SWI using its package manager.
To install simply do:

?- pack_install(os_sub).

And then load by:
?- [library(os_sub)].
