Re: [Rpm-maint] [rpm-software-management/rpm] RFE: Add shorthand syntax for default macro values (#1756)

2021-10-26 Thread Michael Schroeder 
Ohh, non-emptyness instead of plain definedness? Like in most shells: 
`${foo-bar}` versus `${foo:-bar}`...

More thinking out loud, `%{foo|bar}` as a shorthand for the actual expression 
(`%["%{?foo}" || "bar")

Just thinking out loud:
```
%{!foo:bar}
%{?foo-bar}
```

[Rpm-maint] [rpm-software-management/rpm] RFE: Add shorthand syntax for default macro values (#1756)

2021-08-17 Thread Panu Matilainen 
A common use-case with macros is wanting to fallback to a default value if the 
macro in question doesn't exist, eg "use value of %foo if defined, or 5 
otherwise". This seems unnecessarily clumsy in the current macro 
implementation: `%{?foo}%{!?foo:5}` and the new expression stuff doesn't seem 
to help here.
