Regular Expression Matching with a Trigram Index or How Google Code Search Worked
Regular Expression Matching with a Trigram Index or How Google Code Search Worked Russ Cox [email protected] January 2012 Introduction In the summer of 2006, I was lucky enough to be an intern at Google. At the time, Google had an internal tool called gsearch that acted as if it ran grep over all the files in the Google source tree and printed the results. Of course, that implementation would be fairl

Regular Expression Matching Can Be Simple And Fast
Regular Expression Matching Can Be Simple And Fast (but is slow in Java, Perl, PHP, Python, Ruby, ...) Russ Cox [email protected] January 2007 Introduction This is a tale of two approaches to regular expression matching. One of them is in widespread use in the standard interpreters for many languages, including Perl. The other is used only in a few places, notably most implementations of awk and grep.
