does not find mysql.sock (only looks inside /tmp)

having it working out of the box on ubuntu would be great

Use MYSQL_UNIX_PORT environment variable.

For Ubuntu:

export MYSQL_UNIX_PORT=/var/run/mysqld/mysqld.sock

Thanks for the reply, but having it working out of the box would be very nice, just add something like socket = /var/run/mysqld/mysqld.sock if os =~ /Ubuntu/

To automatically determine the location of the socket file is not possible.
If you know the socket file path, change MYSQL_UNIX_PORT in mysql.rb.

if its not possible why does it work in the normal mysql ?
detect os -> guess default <-> overwritten by MYSQL_UNIX_PORT

On Ubuntu, if you use mysql deb package, default path of socket file is /var/run/mysqld/mysqld.sock. If you use mysql binary tarball from mysql.com, it is /tmp/mysql.sock.
In either case, socket file path is changable by mysqld --socket option.
So, the socket file path is not determined by the OS.
