Is the best way for me to learn about how to use Racket paths:
a) by asking the question in this mailing list,
OR,
b) by looking in some repository that has information on this. (If I
should look in a repository, which one?)
It is usually a good idea to check the documentation first.
One of the most useful path-related procedures is "build-path". For
example, since you mentioned "directory-list"... You can use
"build-path" to qualify a relative path produced by "directory-list"
with the directory you gave as an argument to "directory-list":
#lang racket/base
(define my-dir-path (string->path "/home/user"))
(define my-relative-paths (directory-list my-dir-path))
my-relative-paths
;==> '(#<path:foo> #<path:bar>)
(map (lambda (my-relative-path)
(build-path my-dir-path my-relative-path))
my-relative-paths)
;;==> '(#<path:/home/user/foo> #<path:/home/user/bar>)
