Support module for recently introduced function in stdlib
extension name is the shortest suffix ext of name0 where:
name0 is the longest suffix of name that does not contain a directory separator;ext does not starts with a period (such as name0 ^ "." ^ ext = name)ext plus the dot is preceded by at least one non-period character in name0.If such a suffix does not exist, extension name is the empty string.
Return the given file name without its extension, as defined in extension. If the extension is empty, the function returns the given file name.
The following invariant holds for any file name s: remove_extension s ^ "." ^ extension s = s
split_on_dirs path splits the file path path on the platform's directory seperator and on forward slashes (/).
Forward slashes are always included as a split character because on Windows the predominant means of accessing OCaml is through a Unix emulation shell (Cygwin or MSYS2).
