The pathname library has the #absolute? method, but that only checks whether the path starts with a slash, which is not appropriate for Windows. I thought of reimplementing it as something like File.absolute_path(self) == self, but that would mean accessing the filesystem, which I don't think we want here. I also thought of implementing the "windows letter checks" in the pathname's library, but then I saw that those are already implemented in file.c, so I thought it would be a good idea to expose those. So I propose to add File.absolute_path? for this. If this is accepted, I can do a follow-up PR to change Pathname#absolute? to delegate to File.absolute_path?. What do you think? I attach a patch to add `File.absolute_path?` here (I also opened a PR on Github: https://github.com/ruby/ruby/pull/2198). ---Files-------------------------------- 0001-Add-File.absolute_path.patch (3.24 KB) -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
