openguides::config

OpenGuides::Config(3pm) 				User Contributed Perl Documentation				   OpenGuides::Config(3pm)

NAME

       OpenGuides::Config - Handle OpenGuides configuration variables.

DESCRIPTION

       Does config stuff for OpenGuides.  Distributed and installed as part of the OpenGuides project, not intended for independent installation.
       This documentation is probably only useful to OpenGuides developers.

METHODS

       new
	     my $config = OpenGuides::Config->new( file => "wiki.conf" );

	   Initialises itself from the config file specified.  Variables which are not set in that file, and which have sensible defaults, will be
	   initialised as described below in ACCESSORS; others will be given a value of "undef".

	     my $config = OpenGuides::Config->new( vars => { dbname => "foo" } );

	   As above but gets variables from a supplied hashref instead.

ACCESSORS

       Each of the accessors described below is read-write.  Additionally, for each of them, there is also a read-write accessor called, for
       example, "dbname__qu".  This will contain an English-language question suitable for asking for a value for that variable.  You shouldn't
       write to them, but this is not enforced.

       The defaults mentioned below are those which are applied when "->new" is called, to variables which are not supplied in the config file.

       o   dbuser
