DESCRIPTION

FUNCTIONS

$f = field_capitalize($field_name)

Returns the field name properly capitalized. All characters are lowercase, except the first of each word (words are separated by a hyphen in field names).

field_is_official($fname)

Returns true if the field is official and known.

field_is_allowed_in($fname, @types)

Returns true (1) if the field $fname is allowed in all the types listed in the list. Note that you can use type sets instead of individual types (ex: CTRL_FILE_CHANGES | CTRL_CHANGELOG).

field_allowed_in(A|B, C) returns true only if the field is allowed in C and either A or B.

Undef is returned for non-official fields.

field_transfer_single($from, $to, $field)

If appropriate, copy the value of the field named $field taken from the $from Dpkg::Control object to the $to Dpkg::Control object.

Official fields are copied only if the field is allowed in both types of objects. Custom fields are treated in a specific manner. When the target is not among CTRL_PKG_SRC, CTRL_PKG_DEB or CTRL_FILE_CHANGES, then they are always copied as is (the X- prefix is kept). Otherwise they are not copied except if the target object matches the target destination encoded in the field name. The initial X denoting custom fields can be followed by one or more letters among "S" (Source: corresponds to CTRL_PKG_SRC), "B" (Binary: corresponds to CTRL_PKG_DEB) or "C" (Changes: corresponds to CTRL_FILE_CHANGES).

Returns undef if nothing has been copied or the name of the new field added to $to otherwise.

field_transfer_all($from, $to)

Transfer all appropriate fields from $from to $to. Calls field_transfer_single() on all fields available in $from.

Returns the list of fields that have been added to $to.

field_ordered_list($type)

Returns an ordered list of fields for a given type of control information. This list can be used to output the fields in a predictable order. The list might be empty for types where the order does not matter much.

field_list_src_dep()

List of fields that contains dependencies-like information in a source Debian package.

field_list_pkg_dep()

List of fields that contains dependencies-like information in a binary Debian package. The fields that express real dependencies are sorted from the stronger to the weaker.

field_get_dep_type($field)

Return the type of the dependency expressed by the given field. Can either be "normal" for a real dependency field (Pre-Depends, Depends, ...) or "union" for other relation fields sharing the same syntax (Conflicts, Breaks, ...). Returns undef for fields which are not dependencies.

field_get_sep_type($field)

Return the type of the field value separator. Can be one of FIELD_SEP_UNKNOWN, FIELD_SEP_SPACE, FIELD_SEP_COMMA or FIELD_SEP_LINE.

field_register($field, $allowed_types, %opts)

Register a new field as being allowed in control information of specified types. %opts is optional

field_insert_after($type, $ref, @fields)

Place field after another one ($ref) in output of control information of type $type.

field_insert_before($type, $ref, @fields)

Place field before another one ($ref) in output of control information of type $type.
