|Mail::SpamAssassin::Conf::Parser(3)||User Contributed Perl Documentation||Mail::SpamAssassin::Conf::Parser(3)|
This class is used internally by SpamAssassin to parse its configuration files. Please refer to the "Mail::SpamAssassin" documentation for public interfaces.
- the name of the setting it modifies, e.g. "required_score". this also doubles as the default for 'command' (below). THIS IS REQUIRED.
- The command string used in the config file for this setting. Optional; 'setting' will be used for the command if this is omitted.
- An [aryref] of other aliases for the same command. optional.
- 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 "whitelist_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 $CONF_TYPE_HASH_KEY_VALUE-type settings require that the value be non-empty, otherwise they'll produce a warning message.
- A subroutine to deal with the setting. ONE OF code OR type
IS REQUIRED. The arguments passed to the function are
"($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 code subroutine may return to signal that there is an error in the configuration:
$Mail::SpamAssassin::Conf::MISSING_REQUIRED_VALUE -- this setting requires that a value be set, but one was not provided.
$Mail::SpamAssassin::Conf::INVALID_VALUE -- this setting requires a value from a set of 'valid' values, but the user provided an invalid one.
$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 "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.
- 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.
- Set to 1 if this setting requires 'allow_user_rules' when run from spamd.
- 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.)
- Set to 1 if this value occurs frequently in the config. this means it's looked up first for speed.
