Module: Magicprotorb::Naming

Defined in:
lib/magicprotorb/naming.rb

Overview

Translates proto identifiers into Ruby constant names exactly the way protoc’s Ruby generator does, so the constants magicprotorb synthesizes are identical to those a checked-in ‘*_pb.rb` would define.

package my_co.sub_pkg.v1  ->  MyCo::SubPkg::V1
message OuterMsg          ->  OuterMsg            (nested under its parent)

Each dot-separated package segment is split on “_” and each part is capitalized (my_co -> MyCo, v1 -> V1); message/enum names keep their own casing with only the first letter forced upper.
