[SR-Users] Substdef syntax change?

[Daniel-Constantin Mierla]

Hello,

the syntax is flexible it terms of the delimiter character, being
borrowed from the sed tool. Practically you can replace / with any other
character to make it easier to write your substitution expression.

The ! is used for DBURL because there are / in the content (like:
mysql://...) which should be escaped (like: mysql:\/\/:...) if / would
be used as delimiter.

So, you can use whatever delimiter you want and should be fine, like:
"/regexp/subst/flags", "!regexp!subst!flags" or "ZregexpZsubstZflags".

Cheers,
Daniel
