Module: Lyman::CLI::Planter

Defined in:
lib/lyman/cli/planter.rb

Overview

Turns a registry entry into planted bytes and writes them. Rendering and hashing are kept together deliberately: the hash must always be a hash of what actually landed on disk (banner included), never of the bare source file, or update would flag every managed artifact as locally modified on first run.
