Overview

Registry of per-platform frame normalizers, reached as Sentiero.configuration.fingerprint. ErrorsApp resolves an incoming occurrence's optional "platform" tag against this registry to pick the normalizer passed to Fingerprint.compute.

Instance Method Details

#register(name, callable) ⇒ Object

Registering an existing name overrides it, so operators may replace a built-in (e.g. swap out "ruby") as well as add new platforms.

def register(name, callable)
  @normalizers[name.to_s] = callable
end

#resolve(platform) ⇒ Object

Three-tier resolution (see design doc): a reporter that never learned about the "platform" field must keep grouping exactly as before (absent/blank -> default_platform's normalizer, tier 1), whereas a reporter that declares a platform we don't recognize should not have a foreign grammar mis-applied to it (unregistered -> generic, tier 3).
