How I test RPM Conditionals ? in shell command line

[Sérgio Basto]

Hi,

How I can check RPM Conditionals [1], for example How I can check what
is the result of: 

%if 1 
  echo 1; 
%else 
  echo 0; 
%endif 

Best regards,

You can use `%bcond_with foo` (foo is not set as "false") or
`%bcond_without foo` (foo is set as "true") syntax.

```
%bcond_without foo # foo is set as true

%if %{with foo}
  echo 1
%else
  echo 0
%endif
```

Then run `mock --with foo *.rpm` or `mock --without foo *.rpm` for the
SRPM file.

Not sure if there's a way to test a conditional by itself, but if it's somewhere
in a spec file,
you can use "rpmspec --parse $FILE" to see what the spec looks like after
it's parsed
and all the conditionals have been evaluated.

Yah, I usually ends in writing super simple no-build package like:
https://bugzilla.redhat.com/show_bug.cgi?id=2001567#c12

and in MC or via rpm scriplet listing, check the outputs...

%bcond_with{,out} has very ugly reverse syntax. I recently got rid of 
them in all my packages.

I agree that the reverse syntax confuses people and not sure why this
is a specification. Did you find a better alternative syntax?

Now I'm using the following:

%global enable_foo 1

%if %{enable_foo}
...
%endif

Sorry , I want to test RPM Conditionals generally like 

%if !0%{?fedora} < 22
echo yes
%endif

%if ! 0%{?rhel} < 8
echo yes
%endif

%if !0%{?fedora}%{?rhel} || 0%{?fedora} >= 15 || 0%{?rhel} >= 7
echo yes
%endif

I use %bcond , with %bcond we can manipulate mock builds with --with ou
--without .
In my opinion the most confuse of %bcond is not have %without tag . I
think that is address here : 
https://github.com/rpm-software-management/rpm/pull/1520

As a reference, you can also manipulate the mock builds with `mock
--define="enable_foo 0"` or `-D` on Vitaly's way too.

Yes it confuses a lot of people. However they are widely used and thus 
impossible to change, so its just better get used to it. The trick is to 
remember that

   %bond_with / %bcond_without are macros to *add an option build
   with or without* a capability, respectively.

That adding such an option effectively also defines a default which is 
reverse of the macro added is merely a side-effect.

It's perhaps a strange way to approach the problem, but these are old 
old macros (from 2004), I think PLD was way ahead of others in utilizing 
rpm macros etc for general distro benefit.
