=head1 NAME

Sympa::ListDef - Definition of list configuration parameters

=head1 DESCRIPTION

This module keeps definition of configuration parameters for each list.

=head2 Global variable

=over

=item %alias

Deprecated by Sympa 6.2.16.

=item %pgroup

TBD.

=item %pinfo

This hash COMPLETELY defines ALL list parameters.
It is then used to load, save, view, edit list config files.

List parameters format accepts the following keywords :

=over

=item context

TBD.

Introduced on Sympa 6.2.57b.

=item format

Regexp applied to the configuration file entry.
Or arrayref containing all possible values of parameter.

Or, if the parameter is paragraph, value of this item is a hashref containing
definitions of sub-parameters.

See also L<Sympa::List::Config/"Node types">.

=item format_s

Template of regexp applied to the configuration file entry;
see also L</format>.

Subpatterns C<$word> indicate the name of pattern defined in
L<Sympa::Regexps>.

This was introduced on Sympa 6.2.19b.2.

=item file_format

Config file format of the parameter might not be
the same in memory.

=item split_char

Character used to separate multiple parameters.
Used with the set or the array of scalars.

=item length

Length of a scalar variable ; used in web forms.

=item scenario

Tells that the parameter is a scenario, providing its name.

=item default

Default value for the param ; may be a robot configuration
parameter (conf).

If occurrence is C<0-1> or C<0-n>,
default value will be assigned
only when list is created or new node is added to configuration.

=item default_s

Template of constant used as default value in configuration file entry;
see also L</default>.

Subpatterns C<$WORD> indicate the name of constant defined in
L<Sympa::Constants>.

=item synonym

Defines synonyms for parameter values (for compatibility
reasons).

=item gettext_unit

Unit of the parameter ; this is used in web forms and refers
to translated
strings in NLS catalogs.

=item occurrence

Occurrence of the parameter in the config file
possible values: C<0-1>, C<1>, C<0-n> and C<1-n>.
Example: A list may have multiple owner.

See also L<Sympa::List::Config/"Node types">.

=item gettext_id

Title reference in NLS catalogs.

=item gettext_comment

Description text of a parameter.

=item group

Group of parameters.

=item obsolete

Obsolete parameter ; should not be displayed
nor saved.

As of 6.2.16, if the value is true value and is not C<1>,
it defines reference to a fully upper-compatible new parameter.

=item obsolete_values

B<Deprecated>.

Defined obsolete values for a parameter.
These values should not get proposed on the web interface
edition form.

=item not_before, not_after

The duration between these versions (inclusive) during which the parameter
is available.

Introduced on Sympa 6.2.65b.

=item order

Order of parameters within paragraph.

=item internal

Indicates that the parameter is an internal parameter
that should always be saved in the config file.

=item field_type

Used to special treatment of parameter value to show it.

=over

=item C<'dayofweek'>

Day of week, C<0> - C<6>.

=item C<'lang'>

Language tag.

=item C<'password'>

The value to be concealed.

=item C<'reception'>

Reception mode of list member.

=item C<'status'>

Status of list.

=item C<'listtopic'>

List topic.

=item C<'unixtime'>

The time in second from Unix epoch.

=item C<'visibility'>

Visibility mode of list member.

=back

Most of field types were introduced on Sympa 6.2.17.

=item filters

See L<Sympa::List::Config/"Filters">.

Introduced on Sympa 6.2.17.

=item validations

See L<Sympa::List::Config/"Validations">.

Introduced on Sympa 6.2.17.

=item privilege

I<Dynamically assigned>.
Privilege for specified user:
C<'write'>, C<'read'> or C<'hidden'>.

Introduced on Sympa 6.2.17.

=item enum

I<Automatically assigned>.
TBD.

Introduced on Sympa 6.2.17.

=item file

Conf file where the parameter is defined.
"wwsympa.conf" is a synonym of "sympa.conf".
It remains there in order to migrating older versions of config.

=item db

'db_first', 'file_first' or 'no'.
TBD.

=back

=item %user_info

TBD.

=head1 HISTORY

L<Sympa::ListDef> was separated from L<List> module on Sympa 6.2.
On Sympa 6.2.57b, its content was moved to L<Sympa::Config::Schema>.

L<confdef> was separated from L<Conf> on Sympa 6.0a,
and renamed to L<Sympa::ConfDef> on 6.2a.39.
On Sympa 6.2.57b, its content was moved to L<Sympa::Config::Schema>.

Descriptions of parameters in this source file were partially taken from
chapters "sympa.conf parameters" in
I<Sympa, Mailing List Management Software - Reference manual>, written by
Serge Aumont, Stefan Hornburg, Soji Ikeda, Olivier SalaE<252>n and
David Verdin.
