Public Instance methods

dump_hash_public_cache_file()

Write the current hash public cache to the cache file.

[show source] 
   # File lib/roda/plugins/hash_public_cache.rb
82 def dump_hash_public_cache_file
83   File.write(opts[:hash_public_cache_file], (opts[:json_serializer] || :to_json.to_proc).call(opts[:hash_public_cache]))
84   nil
85 end
load_hash_public_cache_file()

Load the hash public cache file, if it exists. This replaces the hash public cache with the values from the file.

[show source] 
   # File lib/roda/plugins/hash_public_cache.rb
45 def load_hash_public_cache_file
46   file = opts[:hash_public_cache_file]
47   return unless File.file?(file)
48 
49   cache = opts[:hash_public_cache] = (opts[:json_parser] || ::JSON.method(:parse)).call(::File.read(file))
50   cache.each_value(&:freeze)
51   nil
52 end
scan_hash_public_cache_dir()

Scan the public directory for files, computing the hash public digest for each. This will not rescan files that already have digest values. If a block is given, it will only calculate the digest for the file if the block returns truthy.

[show source] 
   # File lib/roda/plugins/hash_public_cache.rb
58 def scan_hash_public_cache_dir
59   cache = opts[:hash_public_cache]
60 
61   # Public root doesn't have trailing slash even if given, as
62   # File.expand_path removes it.
63   root = opts[:public_root] + File::SEPARATOR
64 
65   Find.find(opts[:public_root]) do |file|
66     if File.file?(file)
67       file = file.sub(root, '')
68       next if cache[file]
69 
70       if defined?(yield)
71         next unless yield file
72       end
73 
74       cache[file] = hash_path_digest(file)
75     end
76   end
