package FS::Conf;
use vars qw($default_dir);
use IO::File;
$default_dir='/var/spool/freeside/conf';
=head1 NAME
FS::Conf - Read access to Freeside configuration values
=head1 SYNOPSIS
use FS::Conf;
$conf = new FS::Conf;
$conf = new FS::Conf "/non/standard/config/directory";
$dir = $conf->dir;
$value = $conf->config('key');
@list = $conf->config('key');
$bool = $conf->exists('key');
=head1 DESCRIPTION
Read access to Freeside configuration values. Keys currently map to filenames,
but this may change in the future.
=head1 METHODS
=over 4
=item new [ DIRECTORY ]
Create a new configuration object. Optionally, a non-default directory may
be specified.
=cut
sub new {
my($proto,$dir) = @_;
my($class) = ref($proto) || $proto;
my($self) = { 'dir' => $dir || $default_dir } ;
bless ($self, $class);
}
=item dir
Returns the directory.
=cut
sub dir {
my($self) = @_;
$self->{dir};
}
=item config
Returns the configuration value or values (depending on context) for key.
=cut
sub config {
my($self,$file)=@_;
my($dir)=$self->dir;
my $fh = new IO::File "<$dir/$file" or return;
if ( wantarray ) {
map {
/^(.*)$/ or die "Illegal line in $dir/$file:\n$_\n";
$1;
} <$fh>;
} else {
<$fh> =~ /^(.*)$/ or die "Illegal line in $dir/$file:\n$_\n";
$1;
}
}
=item exists
Returns true if the specified key exists, even if the corresponding value
is undefined.
=cut
sub exists {
my($self,$file)=@_;
my($dir) = $self->dir;
-e "$dir/$file";
}
=back
=head1 BUGS
The option to specify a non-default directory should probably be removed.
Write access (with locking) should be implemented.
=head1 SEE ALSO
config.html from the base documentation contains a list of configuration files.
=head1 HISTORY
