NAME

Lemonldap::Config::Parameters - Perl extension for lemonldap SSO system

SYNOPSIS

 #!/usr/bin/perl 
 use strict;
 use Lemonldap::Config::Parameters;
 use Data::Dumper;
 my $nconfig= Lemonldap::Config::Parameters->new(
                            file  =>'applications.xml',
                            cache => 'CONF' );
 my $conf= $nconfig->getAllConfig;
 my $cg=$nconfig->getDomain('appli.cp');
 my $ligne= $cg;
 print Dumper( $ligne);
 my $e = $cg->{templates_options} ;
 my $opt= "templates_dir";
 my $va = $cg->{$opt};
 my $ligne= $nconfig->formateLineHash($e,$opt,$va) ;

or by API :

Lemonldap::Config::Parameters::f_delete('CONF');

or by command line 

perl -e "use Lemonldap::Config::Parameters;Lemonldap::Config::Parameters::f_delete('CONF');"

DESCRIPTION

Lemonldap is a SSO system under GPL.

Login page , handlers must retrieve their configs in an unique file eg :"applications.xml" This file has a XML structrure . The parsing phase may be heavy . So lemonldap can cache the result of parsing in memory with IPC. For activing the cache you must have in the config :

<cache id="CONF" ConfigTtl="1000"> 
</cache>
with :  name='CONF' it's the  GLUE value : four letters (see  IPC::Shareable documentation) .
       ttl: time to live in second   ( 0 for not reload ) 
if ttl is too short the config file will be reload very offen .
 
You can force the reload by command line  
   perl -e "use Lemonldap::Config::Parameters;Parameters::f_delete('CONF');"
or  perl -e "use Lemonldap::Config::Parameters;Parameters::f_reload('CONF');"

WITHOUT CACHE SPECIFICATION , LEMONLDAP DOESN'T USE CACHE ! It  will read and parse config file each time.

METHODS

new (file =>'/foo/my_xml_file.xml' , cache => 'CONF' ); # with IPC cache

or 
       new(file  =>'/foo/my_xml_file.xml');     # without IPC  cache

getAllConfig

Return the  reference of hash  storing whole the config.

getDomain('foo.bar')

Return the reference of hash of config for domain  
If the config file has only one domain , domain may bo omit .

eg : for the xml config file : <domain name="foo.bar" cookie=".foo.bar" path ="/" templates_dir="/opt/apache/portail/templates" templates_options = "ABSOLUTE => '1', INCLUDE_PATH => 'templates_dir'" login ="http://cportail.foo.bar/portail/accueil.pl" menu= "http://cportail.foo.bar/portail/application.pl" ldap_server ="cpldap.foo.bar" ldap_port="389" DnManager= "cn=Directory Manager" passwordManager="secret" branch_people="ou=mefi,dc=foo,dc=bar" session="memcached" > </domain>

   my $cg = $nconfig->getDomain();

DB<2> x $cg
 0  HASH(0x89b108c)
  'DnManager' => 'cn=Directory Manager'
  'branch_people' => 'ou=mefi,dc=foo,dc=bar'
  'cookie' => '.foo.bar'
  'ldap_port' => 389
  'ldap_server' => 'cpldap.foo.bar'
  'login' => 'http://cportail.foo.bar/portail/accueil.pl'
  'menu' => 'http://cportail.foo.bar/portail/application.pl'
  'passwordManager' => 'secret'
  'path' => '/'
  'session' => 'memcached'
  'templates_dir' => '/opt/apache/portail/templates'
  'templates_options' => 'ABSOLUTE => \'1\', INCLUDE_PATH => \'templates_dir\'

ref_of_hash : formateLineHash(string:line);

    or  formateLineHash(string:line,string:motif,string:key);

Return a anonyme reference on  hash  and may replace the motif in the value of key by the value of another key  :

eg 

my $e = $cg->{templates_options} ;
my $opt= "templates_dir";
my $va = $cg->{$opt};
my $ligne= $nconfig->formateLineHash($e,$opt,$va) ;

gives :  
 DB<1> x $ligne
0  HASH(0x848b778)
  'ABSOLUTE' => 1
  'INCLUDE_PATH' => '/opt/apache/portail/templates'

 $ligne can be use directly like option for somes instructions

ref_of_array : formateLineArray(string:line);

    or  formateLineArray(string:line,string:motif,string:key);

Return a anonyme reference on  array  and may replace the motif in the element by the value of another key  :

  the return value can be use directly like option for somes instructions

findParagraph(chapter[,section])

Find and return a reference of chapter finds in xml file , a section can be specified.

Functions

The next acces on cache will need to read file before .
