Overview

LafcadioConfig is a Hash that takes its data from the config file. You’ll have to set the location of that file before using it: Use LafcadioConfig.set_filename.

LafcadioConfig expects its data to be colon-delimited, one key-value pair to a line. For example:

dbuser:user
dbpassword:password
dbname:lafcadio_test
dbhost:localhost
dbtype:Mysql ("Mysql" is the default; select "Pg" for Postgres)
