Path.relative_to

You're seeing just the function relative_to, go back to Path module for more information.

relative_to(path, from)

Specs

relative_to(t(), t()) :: binary()

Returns the given path relative to the given from path.

In other words, this function tries to strip the from prefix from path.

This function does not query the file system, so it assumes no symlinks between the paths.

In case a direct relative path cannot be found, it returns the original path.

Examples

iex> Path.relative_to("/usr/local/foo", "/usr/local")
"foo"

iex> Path.relative_to("/usr/local/foo", "/")
"usr/local/foo"

iex> Path.relative_to("/usr/local/foo", "/etc")
"/usr/local/foo"

iex> Path.relative_to("/usr/local/foo", "/usr/local/foo")
"."
