It will get improperly modified by subExt(), to Foo.new
The gsub line should be /\.[^.]+/ rather than /\..+/. The extension itself should not contain any periods.
Also, there is nothing wrong with adding a newext onto a file with no extension... for example, subExt("My File", "txt") should return "My File.txt".
# change ext
def Dir.subExt( filename , newext )
newext = ('.'+newext) if newext[0] != '.'
if filename.rindex('.')
filename.sub!( /\.[^.]+/,newext )
else
filename << newext
end
end
