regexp error in `aide` macro definition

In my aide config file, I am getting an 'Error in selective regexp' error with a macro like

@@define BDIRS {ABC,ABD}

used as follows

/backup/@@{BDIRS}$ ...
/backup/{ABC,ABD}$ ... <<< this also errors out

The reason I want to use a regexp is that I would like exact same rules be applied to both directories.

Is the regexp or macro definition wrong? Is there a better way to check the top sub-directory?

Solution

AIDE is using PCRE (Perl Compatible Regular Expressions), not BASH brace expansions as you tried to use. This syntax should do the job for you:

/backup/(ABC|ABD)$
