I'd be interested too, the best I could find was the "spec file syntax" chapter of the Fedora RPM guide (https://docs-old.fedoraproject.org/en-US/Fedora_Draft_Documentation/0.1/html/RPM_Guide/ch-specfile-syntax.html), and in particular the short section about conditional macros (https://docs-old.fedoraproject.org/en-US/Fedora_Draft_Documentation/0.1/html/RPM_Guide/ch22s02s02.html).

Is there any comprehensive documentation anywhere on the %... syntax? In particular, %{?label}, %{!?label}, and the comparisons and logical ops that are allowed with %if? I've maintainer a spec file for a package of mine for years, and I've never seen comprehensive documentation for this - mostly acquired features using these things via contributions and cargo-culting. I'm writing a spec file for a new package, and went to try find comprehensive reference documentation for the RPM macro language, and... it just doesn't seem to exist?

In reply to Mayank. Can't you just check for eg

%if "%{mymacro}" == "100" || "%{mymacro}" == "x"
...
%endif

(I'm surely getting the syntax or the logic wrong, but you get the idea)

This post helped me a bit, however I need not only to check for a numeric value like 100 in the example but even the possibility of the values being a character like 'x'. The value is based on external input. Is there a way to handle this for 'x'?
