A regular expression matcher system, including: a deterministic finite state machine (DFSM); a ternary content addressable memory (TCAM) matcher to compare a word stored at the TCAM matcher to an input stream, wherein the word determines a state-to-state transition of the DFSM from a ...
Some regex engines (such as .NET) can handle context-free expressions, and will work it out. But that's not the case for most standard engines. And even if they do, you'll end up having a complex hard-to-read expression, whereas using a parsing library could make the job easier. ...
The key to this script (and the key to most regular expression scripts) is the Pattern: objRegEx.Pattern = " {2,}" What we're doing here is looking for 2 (or more) consecutive blank spaces. How do we know that this Pattern looks for 2 (or more) blank spaces? Well, inside our ...
Since deploying v11.3.1 (we skipped v11.3.0) in production we've been getting regular reports of our workers failing to load with the error "Syntax error in regular expression", in apparently modern browsers. Sample Code or Instructions to Reproduce You can try visiting https://reviewable.io...

The regular expression cannot match there since it does not find a digit, so the next match fails and the match operator returns the pairs it already found. $_ = "1122a44"; my @pairs = m/\G(\d\d)/g; # qw( 11 22 ) You can also use the \G anchor in scalar context. You ...
