Overview

Package to parse a tag.

Tags are annotation with struct fields, that allow for some elegant solutions for different problems. Examples are validation and alike. This is an example on what that might look like:

type Example struct {
	AField string `tagName1:"tagValue1" tagName2:"tagValue2"`
}

As the syntax is somewhat weird and the tag interface only supports a getter, this tag parser was written. It will use go's tag parser to retrieve the tag for a given prefix, parse the value, and return a map of strings to strings. Keys and values are separated by an equal sign '=', values might be quoted using single quotes "'", and key-value pairs are separated using whitespace.
