Combine absolute path and relative path to get a new absolute path

Question

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

Answer 1

Stephen's answer is correct, but I wanted to add something to save future readers some time:

You should note functions within the path package assume the separator is /. When using the example above, I kept getting the output . since I had a Window's file path using \.

If you're not manipulating URLs, consider using the filepath package which uses the OS's directory separator.

E.g. When running on Windows:

path.Dir("C:\\Users\\Darren\\Desktop\\file.txt")
filepath.Dir("C:\\Users\\Darren\\Desktop\\file.txt")

Returns:

.
C:\Users\Darren\Desktop

Answer 2

The path.Join when used with path.Dir should do what you want. See http://golang.org/pkg/path/#example_Join for an interactive example.

path.Join(path.Dir("/help/help1.html"), "../content.txt")

This will return /content.txt.
