=head1 NAME

=encoding utf8

Lemonldap::NG::Manager::Build - Static files generator of Lemonldap::NG Web-SSO
system.

=head1 SYNOPSIS

  use Lemonldap::NG::Manager::Build;
  
  Lemonldap::NG::Manager::Build->run(
    structFile            => "site/htdocs/static/struct.json",
    confTreeFile          => "site/htdocs/static/js/conftree.js",
    managerConstantsFile  => "lib/Lemonldap/NG/Common/Conf/ReConstants.pm",
    managerAttributesFile => 'lib/Lemonldap/NG/Manager/Attributes.pm',
    defaultValuesFile     => "lib/Lemonldap/NG/Common/Conf/DefaultValues.pm",
    firstLmConfFile       => "_example/conf/lmConf-1.json",
    reverseTreeFile       => "site/htdocs/static/reverseTree.json",
  );

=head1 DESCRIPTION

Lemonldap::NG::Manager::Build is only used to build javascript files and
Lemonldap::NG constants Perl files. It must be launched after each change.

=head2 DEVELOPER CORNER

To add a new parameter, you have to:

=over

=item declare it in Manager/Build/Attributes.pm;

=item declare its position in the tree in Manager/Build/Tree.pm (or
Manager/Build/CTrees.pm for complex nodes);

=item refresh files by using this (or launch any build makefile target at the
root of the Lemonldap::NG project sources).

=back

See below for details.

=head3 Files generated

`scripts/jsongenerator.pl` file uses Lemonldap::NG::Manager::Build::Attributes,
Lemonldap::NG::Manager::Build::Tree and Lemonldap::NG::Manager::Build::CTrees to generate

=over

=item `site/htdocs/static/struct.json`:

Main file containing the tree view;

=item `site/htdocs/static/js/conftree.js`:

generates Virtualhosts, SAML and OpenID-Connect partners sub-trees;

=item `site/htdocs/static/reverseTree.json`:

map used by manager diff to find attribute position in the tree;

=item `Lemonldap::NG::Manager::Constants`:

constants used by all Perl manager components;

=item `Lemonldap::NG::Common::Conf::DefaultValues`:

constants used to read configuration;

=item `Lemonldap::NG::Manager::Attributes`:

parameters attributes used by the manager during configuration upload;

=item lmConf-1.json:

first configuration in file format;

=back

=head3 Attribute declaration

set your new attribute as a key of attributes() function that points to a hash
ref containing:

=over

=item type (required):

content type must be declared in sub types() in the same file
(except if attribute embeds its own tests) and must match
to a form stored in static/forms/ directory;

=item help (optional):

Relative HTML path to help page (relative to
/doc/pages/documentation/<version>/);

=item default (recommended):

default value to set if not defined;

=item select (optional):

required only if type is `select`. In this case, it
must contain an array of { k => <keyName>, v => <display name> } hashref

=item documentation (recommended):

some words for other developers

=item test (optional):

if test is not defined for this type or if test must
be more restrictive, set here a regular expression or a subroutine. Arguments
passed to subroutine are (keyValue, newConf, currentKey). It returns 2
arguments: a boolean result and a message (if non empty message will be
displayed as warning or error depending of result);

=item msgFail (optional):

for regexp based tests, message to display in case of
error. Words to translate have to be written as so: __toTranslate__;

=item keyTest (optional):

for keys/values attributes, test to be applied on key;

=item keyMsgFail (optional):

for regexp based key tests, same as msgFail for keys test;

=back

If you want to declare a new type, you have to declare following
properties:

=over

=item test, msgFail, keyTest, keyMsgFail as shown above,

=item form: form to use if it doesn't have the same name.

=back

=head3 Tree location

The tree is now very simple: it contains nodes and leaves. Leaves are designed only
by their attribute name. All description must be done in the file described
above. Nodes are array member designed as this:

  {
    title => 'titleToTranslate',
    help  => 'helpUrl',
    form  => 'relativeUrl',
    nodes => [
      ... nodes or leaf ...
    ]
  }

Explanations:

=over

=item title (required):

it must contain an entry of static/languages/lang.json

=item help (recommended):

as above, the relative HTML path to the help page
(relative to /doc/pages/documentation/<version>/);

=item form (optional):

the name of a static/forms/<name>.html file

=item nodes:

array of sub nodes and leaf attached to this node

=item group:

must never be used in conjunction with nodes. Array of leaves only
to be displayed in the same form

=item nodes_cond:

array of sub nodes that will be displayed with a filter. Not yet
documented here, see the source code of site/htdocs/static/js/filterFunctions.js.

=item nodes_filter:

filter entry in site/htdocs/static/js/filterFunctions.js for the same feature.
