As I promised, this is implementation with the '-n' parameter:
```
%define gemspec_add_runtime_dependency(n:) \
read -d '' add_runtime_dependency_script << 'EOR' || : \
name = '%{-n*}' \
version = %{*} \
spec = Gem::Specification.load('.%{gem_spec}') \
dep = spec.dependencies.detect { |d| d.type == :runtime && d.name ==
name } \
if dep \
dep.requirement.concat version \
else \
spec.add_runtime_dependency name, version \
end \
File.write '.%{gem_spec}', spec.to_ruby \
EOR\
echo "$add_runtime_dependency_script" | ruby \
%{nil}
```
It is a bit more flexible, since what is following behind the name of
the dependency is pasted directly into Ruby code, so either ```['~>
10.0', '>= 10.1']``` or '~> 10.0' are viable options. IOW, it must be
valid ruby code, otherwise the script bails out with error. E.g. for
```
%gemspec_add_runtime_dependency -n fog-dynect ~> 10.0
```
the following error is reported:
```
+ read -d '' add_runtime_dependency_script
+ :
+ echo 'name = '\''fog-dynect'\''
version = ~> 10.0
spec =
Gem::Specification.load('\''./usr/share/gems/specifications/fog-1.38.0.gemspec'\'')
dep = spec.dependencies.detect { |d| d.type == :runtime && d.name ==
name }
if dep
dep.requirement.concat version
else
spec.add_runtime_dependency name, version
end
File.write '\''./usr/share/gems/specifications/fog-1.38.0.gemspec'\'',
spec.to_ruby'
+ ruby
-:2: syntax error, unexpected '>'
version = ~> 10.0
^
```
