Regular Expression Article #4
Posted on Thursday, January 19, 2012.
In January 2007 I posted an article on my web site titled “Regular Expression Matching Can Be Simple And Fast.” I intended this to be the first of three; the second would explain how to do submatching using automata, and the third would explain how to make a really fast DFA. These were inspired by my work on Google Code Search.
Today, the fourth article in my three-part series is available, accompanied by source code (as usual). This one describes how Code Search worked.
