note vitoco <p>I found very interesting this piece of code as an example for the <c>\G</c> pattern, but I noticed that <c>x</c> modifier was missing on each regexp AFAIK, but then tested if there was anything else I'm not awared.</p> <p>Just as it is, it returns nothing on <c>$pat</c>. Then added the <c>x</c> modifier and got an endless loop!</p> <p>I thought it was related to a note in [doc://perlre#Assertions|perlre]: "<i>It is worth noting that <c>\G</c> improperly used can result in an infinite loop.</i>", but a small trace using <c>print "($pat)\n";</c> just before each <c>redo</c> shows that <c>\G</c> is always at the beginning of the argument, not after what was already matched.</p> <p>I tried again removing <c>pos()</c> to see if that function resets the pointer... No luck!</p> <p>Am I doing something wrong?</p> 812624 812628
