Golang : unknown escape sequence error


13379 views 1st July 2015


Encountered a funky error message unknown escape sequence while working this the tutorial on how to find IP address from a string. Apparently, Go doesn't like this statement :

 regexPattern := numBlock + "\." + numBlock + "\." + numBlock + "\." + numBlock

and to fix the error, I've to escape the backslash. 

 regexPattern := numBlock + "\\." + numBlock + "\\." + numBlock + "\\." + numBlock

alternatively, backtick ` can be used to fix the error as well.

 regexPattern := numBlock + `\.` + numBlock + `\.` + numBlock + `\.` + numBlock
