check_paths(master_path, copy_path, **options, &block) click to toggle source

A helper function to check two paths for consistency. Provides callback from Fingerprint::Checker.

# File lib/fingerprint.rb, line 28
def self.check_paths(master_path, copy_path, **options, &block)
        master = Scanner.new([master_path])
        copy = Scanner.new([copy_path])
        
        master_recordset = RecordSet.new
        copy_recordset = SparseRecordSet.new(copy)
        
        master.scan(master_recordset)
        
        checker = Checker.new(master_recordset, copy_recordset, **options)
        
        checker.check(&block)
        
        return checker
end

identical?(source, destination) { |record| ... } click to toggle source

Returns true if the given paths contain identical files. Useful for expectations, e.g. ‘expect(Fingerprint).to be_identical(source, destination)`

# File lib/fingerprint.rb, line 45
def self.identical?(source, destination, &block)
        failures = 0
        
        check_paths(source, destination) do |record, name, message|
                failures += 1
                
                yield(record) if block_given?
        end
        
        return failures == 0
end
