"Abstract" means not tied to actual filesystem. Unix-like means single-root tree, with forward slash "/" as separator, and "." and ".." to mean current- and parent directory. "Naive" means not having the concept of symlinks, so paths need not be traversed on a per-directory basis (see File::Spec::Unix where it mentions the word "naive"). These routines can be useful if you have a tree data and want to let users walk around it using filesystem-like semantics. Some examples of where these routines are used: Config::Tree, Riap (App::riap). FUNCTIONS split_path($path) => LIST OF STR normalize_path($path) => STR is_abs_path($path) => BOOL is_rel_path($path) => BOOL concat_path($path1, $path2, ...) => STR concat_path_n($path1, $path2, ...) => STR abs_path($path) => STR SEE ALSO Path::Abstract a similar module. The difference is, it does not interpret "." and "..". File::Spec::Unix a similar module, with some differences in parsing behavior. HOMEPAGE Please visit the project's homepage at .
