RegExp requires backtracking for some patterns, and backtracking is not supported by the standard Go engine: https://code.google.com/p/re2/wiki/Syntax + +Therefore, the following syntax is incompatible: + + (?=) // Lookahead (positive), currently a parsing error + (?!) // Lookahead (backhead), currently a parsing error + \1 // Backreference (\1, \2, \3, ...), currently a parsing error + +A brief discussion of these limitations: "Regexp (?!re)" https://groups.google.com/forum/?fromgroups=#%21topic/golang-nuts/7qgSDWPIh_E + +More information about re2: https://code.google.com/p/re2/ +
