Module: Beni::BuildConfig

Defined in:
lib/beni/build_config.rb

Overview

Generates the consumer’s editable mruby build config: a verbatim copy of the staged mruby source’s own build_config/default.rb —the configured version’s upstream default. Exposed as rake beni:config by Beni::Tasks; the generated file belongs to the consuming project and seeds further customization.

Class Method Details

.generate(dest, mruby_dir:, version:) ⇒ Object

Copy the staged source’s default config to dest, creating missing parent directories. Requires version‘s mruby source staged under mruby_dir and refuses to clobber an existing (likely hand-tuned) config. Returns dest.

Raises:

def generate(dest, mruby_dir:, version:)
  raise Error, "[beni] #{dest} already exists — delete it first to regenerate" if File.exist?(dest)

  source = staged_default_config(mruby_dir, version)
  FileUtils.mkdir_p(File.dirname(dest))
  FileUtils.cp(source, dest)
  dest
end

.staged_default_config(mruby_dir, version) ⇒ Object

The staged source’s upstream default config path, verified to be version‘s: the .beni-version marker Vendor::Tarball#prepare stamps must match, so a stale tree never seeds a config for the wrong release.
