How to read Perl DB_Files in Ruby

I'm migrating a Perl script to Ruby. The Perl script uses DB_File in DB_HASH mode. How do I read all the keys and values from such a file in Ruby?

Solution

  • I finally realized that DB_HASH is a Berkeley DB file format.

    I didn't have libdb for Ruby on my Ubuntu box but that was fixed with a simple apt-get

    apt-get install libdb4.2-ruby1.8

    Then in Ruby

    require 'bdb'
db=BDB::Hash.open("test.db")
keyvalues=db.to_hash
