Re^3: Perl appending \ or / based on windows or linux

dasgar's point about regexing File::Spec aside, it seems like any application that requires a trailing directory separator is really just not using File::Spec enough. Maybe it's my lack of imagination, but short of this literal spec (as you say, XY Problem) I cannot come up with an appropriate use case.

#11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.

A couple of examples from a previous thread: The behavior of rsync sometimes depends on whether a pathname has a trailing slash or not. Often file patterns, such as in gitignore, will match only directories if there is a trailing slash on the name. However, as was argued in that thread, the forward slash is probably fine in all these applications, and so one solution when dealing with them might be `File::Spec::Unix->catdir('foo','bar').'/'` The only other actual use case I could come up with since then is displaying things to a user: a trailing directory separator makes it obvious that something is a path at first glance. So yeah, "I need a trailing slash" is more likely to be an XY Problem than a practical one...	[reply] [d/l]
