#missing ⇒ Object (readonly)

{ "save" => "lucide/save: not found in provider lucide" } — icons this run could not resolve. Filled by #call; see the comment there.

Instance Method Details

#call(only: nil) ⇒ Object

=> { "save" => Source, ... } keyed by icon name.

One bad name in a manifest of two hundred used to take the whole build down, which meant a typo in an icon nobody had shipped yet blocked everyone. A single icon failing is now recorded in #missing and left out of the result; the caller reports it and builds the rest. Failures that are not per-icon — an unreachable API, a provider that 404s — are still raised, because then nothing would be correct.
