Question

Is there an equivalent to Java's String intern function in Go?

I am parsing a lot of text input that has repeating patterns (tags). I would like to be memory efficient about it and store pointers to a single string for each tag, instead of multiple strings for each occurrence of a tag.

Answer 1

I think that for example Pool and GoPool may fulfill your needs. That code solves one thing which Stephen's solution ignores. In Go, a string value may be a slice of a bigger string. Scenarios are where it doesn't matter and scenarios are where that is a show stopper. The linked functions attempt to be on the safe side.
