Convert string to camel case, snake case, kebab case / slugify, custom delimiter, pad string, tease string and many other functionality with help of by Stringy package. You can convert camelcase to snakecase or kebabcase, or snakecase to camelcase and kebabcase and vice versa. This package was inspired from PHP danielstjules/Stringy.
Golang has very rich strings core package despite some extra helper function are not available and this stringy package is here to fill that void. Plus there are other some packages in golang, that have same functionality but for some extreme cases they fail to provide correct output. This package cross flexibility is it's main advantage. You can convert to camelcase to snakecase or kebabcase or vice versa.

$ dep ensure -add github.com/gobeam/stringyBetween takes two string params start and end which and returns value which is in middle of start and end part of input. You can chain to upper which with make result all uppercase or ToLower which will make result all lower case or Get which will return result as it is.
strBetween := stringy.New("HelloMyName")
fmt.Println(strBetween.Between("hello", "name").ToUpper()) // MYBoolean func returns boolean value of string value like on, off, 0, 1, yes, no returns boolean value of string input. You can chain this function on other function which returns implemented StringManipulation interface.
