Instance Attribute Details

#filters ⇒ Object

File extension filters can be set on DFM.new( { :filters => [“jpg”,“gif”] } ) or you should assign it to the class instance variable filters before calling recurse( path )

Instance Method Details

#hex(duplicates = true) ⇒ Object

Returns hash of duplicate files by MD5 hexdigest index. If the parameter is set to false then the hash returns non-duplicates.

# File 'lib/dfm.rb', line 40

def hex( duplicates = true )
	select_duplicates( { :hash => @files_by_hexdigest, :duplicates => duplicates } )
end

#name(duplicates = true) ⇒ Object

Returns hash of duplicate files by file name index. If the parameter is set to false then the hash returns non-duplicates.

# File 'lib/dfm.rb', line 46

def name( duplicates = true )
	select_duplicates( { :hash => @files_by_name, :duplicates => duplicates } )
end

#print_duplicates(opt = "hex") ⇒ Object

Prints out JSON list of duplicate copy files by MD5 hexdigest index or if the parameter is set to “name” then the list is indexed by file name.

# File 'lib/dfm.rb', line 34

def print_duplicates( opt = "hex" )
	print_match( { :type => opt } )
end

#print_singles(opt = "hex") ⇒ Object

Prints out JSON list of single copy files by MD5 hexdigest index or if the parameter is set to “name” then the list is indexed by file name.

	print_match( { :type => opt, :duplicates => false } )
end

#recurse(path) ⇒ Object

Start a fresh recursive search with empty hash indexes. Accepts parameter for path. (See filters for setting file extensions.)
