What is the regular syntax of ${1:+Devil:devil}? Is there any documentation about it?

[unOmni]

Here's a documentation I found https://www.regexbuddy.com/manual.html#insertreplaceconditional

Regular expression engine do not support this feature

[unOmni]

What does the engine support that could allow for replacement depending on the condition.
