Edit Question
Title
Body
I'm writing a program in which one of the components must be able to take a path it is given (such as /help/index.html , or /help/ ) and a relative path based on that location, (such as ../otherpage/index.html , or sub/dir/of/help/ , or help2.html ) and produce the absolute path implied by the relative path. Consider the following directory tree. / index.html content.txt help/ help1.html help2.html The file index.html contains a link like help/help1.html . The program is passed / or /index.html , and combines it with help/help1.html to get /help/help1.html . Similarly, the file /help/help1.html has the link ../content.txt , from which the program needs to return /content.txt . Is there a reasonable way to do this? Thank you. :) Edit: Thank you to Stephen Weinberg! For everyone from the future , here's the code I used. func join(source, target string) string { if path.IsAbs(target) { return target } return path.Join(path.Dir(source), target) }
