Overview

Central registry for Typelizer multi-writer configuration

Responsibilities:

  • Holds immutable Config per writer name (always includes :default)

  • Maintain flat DSL setters for :default (e.g., config.output_dir = …)

  • Allows defining/updating named writers via writer(:name) { |cfg| … }

  • Check unique output_dir across writers to avoid file conflicts

Config priorities:

  • WriterContext merges in order: library defaults < global_settings < writer < DSL inheritance

  • global_settings are only updated by flat setters, not by writer(:default) blocks

def initialize
  @dirs = []
  @listen = nil

  default = Config.build

  @writers = {DEFAULT_WRITER_NAME => default.freeze}
  @global_settings = {}

  @writer_output_dirs = {DEFAULT_WRITER_NAME => normalize_path(default.output_dir)}
  @used_output_dirs = Set.new(@writer_output_dirs.values.compact)
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args, &block) ⇒ Object (private)

Setters and readers to Writer(:default) config Keep the “flat” setters for the :default writer, for example:

config.output_dir = ...
config.prefer_double_quotes = true

end

#writer(name = DEFAULT_WRITER_NAME, from: nil, &block) ⇒ Object

Defines or updates a writer configuration.

Inherits from the existing writer config (or global_settigns if absent), yields a mutable copy, then freezes and stores it. output_dir is unique and mandatory Also accepts “from” argument, which allows us to inherit configuration from any writer
