In xfun: Supporting Functions for Packages Maintained by 'Yihui Xie'

Test if a path is a subpath of a dir

Description

Check if the path starts with the dir path.

Usage

is_sub_path(x, dir, n = nchar(dir))

Arguments

x	A vector of paths.
dir	A vector of directory paths.
n	The length of dir paths.

Value

A logical vector.

Note

You may want to normalize the values of the x and dir arguments first (with normalize_path()), to make sure the path separators are consistent.

Examples

xfun::is_sub_path("a/b/c.txt", "a/b")  # TRUE
xfun::is_sub_path("a/b/c.txt", "d/b")  # FALSE
xfun::is_sub_path("a/b/c.txt", "a\\b")  # FALSE (even on Windows)
