Having to configure this in a single place would be convenient. OTOH, I can
imagine corner-cases, where a single option would be undesired. One thing we
could do is to allow global options that can be overridden for each check.
Something along the lines of (modulo tests):
```
std::string OptionsView::get(StringRef LocalName, std::string Default) const {
- const auto &Iter = CheckOptions.find(NamePrefix + LocalName.str());
+ auto Iter = CheckOptions.find(NamePrefix + LocalName.str());
if (Iter != CheckOptions.end())
return Iter->second;
+ // Fallback to global setting, if present.
+ Iter = CheckOptions.find(LocalName.str());
+ if (Iter != CheckOptions.end())
+ return Iter->second;
return Default;
}
```
Alternatively, we could add another method (e.g. `getLocalOrGlobal`) to make
the usage of the global setting explicit.
