I'm using named capture buffers within a non-scoping repeat (?: )+
structure where the buffer status (<mybuf>
defined ?) is tested by an if-then-else sequence, e.g.: /(? ... (?(<mybuf>)(?:match something)|(?<mybuf>match something else)) ... )+/
. Now, I would need to reset <mybuf>
(to undef or defined value) within the regexp WITHOUT consuming any character of my match target. Since testing the buffer is possible using ?(<mybuf>)
, I'm speculating that resetting it should also be possible at runtime ?
