Bdb === Your need first this library: http://github.com/DenisKnauf/bdb Download ======== via git: git clone git://github.com/DenisKnauf/sbdb.git Installation ============ gem install sbdb-*.gem or: gem install sbdb --source http://github.com/DenisKnauf/sbdb/raw/master/sbdb-0.0.5.gem Documentation ============= Doesn't exist yet. Usage ===== First, open environment and database require 'sbdb' Dir.mkdir 'newenv' rescue Errno::EEXIST env = SBDB::Env.new 'newenv', SBDB::CREATE db = env.open SBDB::Btree, 'newdb.db', 'mynewdb', SBDB::CREATE It works nearly like a Ruby-Hash: db['key'] = 'value' db['key'] # => 'value' db.to_hash # => {'key'=>'value'} db.map {|k, v| [k, v].join ' => '} # => ["key => value"] db.count # => 1 *SBDB::DB#each* uses a *SBDB::Cursor*: cursor = db.cursor cursor.each {|k,v| puts "#{k}: ${v}" } Don't forget to close everything, you opened! cursor.close db.close env.close But you can use a *lambda* to ensure to close everything: SBDB::Env.new( 'newenv', SBDB::CREATE) do |env| env.open SBDB::Btree, 'newdb.db', 'mynewdb', SBDB::CREATE do |db| db.to_hash end end *SBDB::DB#to_hash* creates a cursor and close it later.
