push(_:)

If other does not have a root, append each component of other. If other has a root, replaces self with other.

Declaration

mutating func push(_ other: FilePath)

Discussion

This operation mimics traversing a directory structure (similar to the cd command), where pushing a relative path will append its components and pushing an absolute path will first clear self’s existing components.

Example:

var path: FilePath = "/tmp"
path.push("dir/file.txt") // path is "/tmp/dir/file.txt"
path.push("/bin")         // path is "/bin"
