Subject Proposed changes to regex_remap core plugin
Date Fri, 13 Nov 2020 18:54:01 GMT
1.  Two-character string substitutions can begin with ^ as well as $.  If ^
is used, and the substitution is a URL component, the component will be the
one in the pristine, rather than the remapped, URL.  So, for example, $h is
the host in the remapped URL, and ^h is the host in the pristine URL.  (^
seems intuitive as "before URL" with $ as "after URL", because ^ means
start of line and $ means end of line in regular expressions.)

2. Add the string substitutions $$ (translating to $) and ^^ (translating
to ^).
