Hi Edmund<br><br>Thank you very much for Regex Coach. It has helped tremendously!<br>Recently I needed to use a negative look-behind with multiple exclusions and found that Regex Coach does not support variable length look-behind.<br>
<br>\\[^\\]*(?<!(tmp|files))$<br><br>gives an error that "Variable length look-behind not implemented (yet)"<br><br>whereas<br><br>\\[^\\]*(?<!(tmp|les))$<br><br>works, except that it excludes more than required.<br>
<br>Interestingly WinMerge also has this restriction ;-)<br><br>Thanks<br>Alex<br>
