Overview

Calculates SHA256 digests for a map of documentation files and their tracked source files.

Input: { "docs/user.md" => ["app/models/user.rb", "app/services/authenticator.rb"], "docs/admin.md" => ["app/models/admin.rb"] }

Output: { "docs/user.md" => { "app/models/user.rb" => "abcd1234...", "app/services/authenticator.rb" => "efgh5678..." }, "docs/admin.md" => { "app/models/admin.rb" => nil # file missing } }

Class Method Details

.run(tracked_files: {}) ⇒ Hash<String, Hash<String, String?>>

Runs the subprocess to calculate SHA256 digests per documentation file and its tracked source files.

Parameters:

  • tracked_files (Hash<String, Array<String>>) (defaults to: {}) —

    Mapping of documentation files to lists of tracked source file paths.

Returns:

  • (Hash<String, Hash<String, String?>>) —

    Mapping of documentation files to tracked source files and their SHA256 digests (or nil if missing).
