(IO::Path) method add

Defined as:

method add(IO::Path:D: Str() $what --> IO::Path:D)

Concatenates a path fragment to the invocant and returns the resultant IO::Path. If adding ../ to paths that end with a file, you may need to call resolve for the resultant path to be accessible by other IO::Path methods like dir or open. See also sibling and parent.

"foo/bar".IO.mkdir;
"foo/bar".IO.add("meow")    .resolve.relative.say; # OUTPUT: «foo/bar/meow␤» 
"foo/bar".IO.add("/meow")   .resolve.relative.say; # OUTPUT: «foo/bar/meow␤» 
"foo/bar".IO.add("meow.txt").resolve.relative.say; # OUTPUT: «foo/bar/meow.txt␤» 
"foo/bar".IO.add("../meow") .resolve.relative.say; # OUTPUT: «foo/meow␤» 
"foo/bar".IO.add("../../")  .resolve.relative.say; # OUTPUT: «.␤»
