Ok, that's true. So when I started diving into the wonderful world of unix like operating system, one of the first things I was taught is "/" starts an absolute path, while "./foo" or just "foo" starts a relative path. And this stuck with me. Now I realize git treats the repository root literally as the root and hence absolute paths starting with "/" make totally sense inside git as the world stops for git outside its work directory. > >> (from man gitignore, though reading that and not finding a './' it may >> need improvement > > We do not allow relative pathname traversal with "." or "..", do we? Because we don't have to. It's always relative to the .gitignore file (foo/.gitignore can talk about bar/ and still mean foo/bar), so we don't need to express the relativity in any special way. > > I would be very hesitant to special case "./*.js" to mean "*.js > files in the same directory as .gitignore appears", as I think it > risks intelligent readers to infer "../foo/*.js" or "../*.js" would > take effect, when placed in "bar/.gitignore".

I rather meant to say the documentation could be filled with examples for common patterns. That way you'd not be required to read all the rules and *think* about them, but rather can just copy/paste and hope it works. ;) Sorry if this sounded otherwise. -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
