path_file

Manipulate file paths

Description

path_file() returns the filename portion of the path, path_dir() returns the directory portion. path_ext() returns the last extension (if any) for a path. path_ext_remove() removes the last extension and returns the rest of the path. path_ext_set() replaces the extension with a new extension. If there is no existing extension the new extension is appended.

Usage

path_file(path)

path_dir(path)

path_ext(path)

path_ext_remove(path)

path_ext_set(path, ext)

path_ext(path) <- value

Arguments

`path`	A character vector of one or more paths.
`ext, value`	The new file extension.

Details

Note because these are not full file paths they return regular character vectors, not fs_path() objects.

Examples

path_file("dir/file.zip")

path_dir("dir/file.zip")

path_ext("dir/file.zip")

path_ext("file.tar.gz")

path_ext_remove("file.tar.gz")

# Only one level of extension is removed
path_ext_set(path_ext_remove("file.tar.gz"), "zip")
