Hi @ahabel ,
I love the idea of this (as I love RegEx) and I feel like this should be achievable and possibly someone has something already out there. I wanted to have a stab at this myself, just haven’t found the time (yet).
Just some thoughts on your RegEx:
While sticking to lower case ascii is probably a good idea, it’s not really required by Solace. Solace supports the full UTF-8 character set and users in APAC will probably find it useful to be able to use Chinese, Japanese, Korean or similar as part of their topic names. I would mainly exclude the use of wildcard characters like “*” and “>” for SMF or “+” and “#” for MQTT in the topic as they can cause issues when trying to match your subscriptions to those topics. Another one to check for is the overall topic length not being larger than 255 characters. Christian
