Normalize Windows Path Names

Brad Tilley

4/6/2006 12:52:00 PM

Is there a way to normalize pathnames? On Windows, many system calls
return a windows path that contains back slashes like this:

C:\windows\system32

I'd prefer to have forward slashes since they are easier to work with
like this:

C:/windows/system32

Windows will accept either slash. What is the best way for Ruby to
convert to normal slashes?

Thank you,
Brad

See String#tr and String#tr!

"C:\\foo\\bar".tr("\\", '/') # C:/foo/bar
