# Do something with $ti / $tag
}

DESCRIPTION

Instances of this class represents the data in the check ``.desc'' files. It allows access to the tags (as Lintian::Tag::Info) and the common meta data of the check (such as Needs-Info).

CLASS METHODS

Lintian::CheckScript->new($basedir, $checkname[, $profile, $lang])

Parses the $file as a check desc file. If $profile and $lang is given, translations for the check will be loaded as well.

$cs->name

Returns the ``name'' of the check script. This is the value in the Check-Script field in the file.

$cs->type

Returns the value stored in the ``Type'' field of the file. For the purpose of testing if the check applies to a given package type, the ``is_check_type'' method can be used instead.

Note in rare cases this may return undef. This is the case for the lintian.desc, where this field is simply not present.

$cs->abbrev

Returns the value of the Abbrev field from the desc file.

$cs->script_path

Returns the (expected) path to the script implementing this check.

needs_info

Returns a list of all items listed in the Needs-Info field. Neither the list nor its contents should be modified.

$cs->is_check_type ($type)

Returns a truth value if this check can be applied to a $type package.

Note if $cs->type return undef, this will return a truth value for all inputs.

$cs->get_tag ($tagname)

Return the tag or undef (if the tag is not in this check).

$cs->tags

Returns the list of tag names in the check. The list nor its contents should be modified.

$cs->load_check

Attempts to load the check. On failure, the load error will be propagated to the caller. On success it returns normally.

$cs->run_check ($proc, $group)

Run the check on $proc, which is in the group $group. $proc should be a lab entry and must have the proper collections run on it prior to calling this method (See Lintian::Unpacker).

The method may error out if loading the check failed or if the check itself calls die/croak/fail/etc.

Returns normally on success; the return value has no semantic meaning and is currently "undef".

NB: load_check can be used to determine if the check itself is loadable.
