Pure filesystem I/O port. Wraps File/FileUtils/Etag with no knowledge of envelopes, entries, schemas, or audit.

Instance Method Details

#delete(path) ⇒ Object

Raises Errno::ENOENT if absent — mirrors File.delete and matches the semantics used by Store::Writer (which guards with File.exist? first).

# File 'lib/textus/port/storage/file_store.rb', line 20

def delete(path) = File.delete(path)

#dir_empty?(dir) ⇒ Boolean

Returns:

  • (Boolean)

def dir_empty?(dir)
  # Dir.empty? exists on modern Rubies; wrap for clarity
  Dir.empty?(dir)
end

#etag(path) ⇒ Object

# File 'lib/textus/port/storage/file_store.rb', line 24

def etag(path) = Value::Etag.for_file(path)

#exists?(path) ⇒ Boolean

Returns:

  • (Boolean)

# File 'lib/textus/port/storage/file_store.rb', line 22

def exists?(path) = File.exist?(path)

#mkdir_p(path) ⇒ Object

Convenience filesystem ops so callers can go through the port instead of calling FileUtils/Dir directly. Keeps filesystem semantics in one place for easier testing and replacement.
