`Web::CSS::Serializer`

A CSS serializer

DESCRIPTION

The Web::CSS::Serializer class has several methods to serialize parsed constructs generated by Web::CSS::Parser into CSS's textual form.

This module is not for general use. For most purposes, applications should use CSSOM standard API implemented by Web::DOM::CSSStyleSheet and related modules.

METHODS

Following methods are available:

$serializer = Web::CSS::Serializer->new: Return a new serializer instance.
$context = $serializer->context
$serializer->context ($context): Return or set the Web::CSS::Context object used for serialization.
$string = $serializer->serialize_mq ($mq): Serialize a media query. See Web::CSS::MediaQueries::Serializer for details.
$string = $serializer->serialize_mq_list ($mq_list): Serialize a list of media queries. See Web::CSS::MediaQueries::Serializer for details.
$string = $serializer->serialize_prop_decls ($style): Return the character string representation of the list of declarations, declaring property values (and important flags) contained by the specified property construct (See Web::DOM::Parser).
$string = $serializer->serialize_prop_priority ($style, $key): Return the character string representation of the important flag of the property. The first argument must be a property construct, possibly containing the property in question (See Web::CSS::Parser). The second argument must be the key identifying the property (See Web::CSS::Props). If the specified property has the important flag, the string important is returned. Otherwise undef is returned.
$string = $serializer->serialize_prop_value ($style, $key): Return the character string representation of the property value. The first argument must be a property construct, possibly containing the property value in question (See Web::CSS::Parser). The second argument must be the key identifying the property (See Web::CSS::Props). If the specified property has no value, undef is returned.
$string = $serializer->serialize_rule ($rule_set, $rule_id): Return the character string representation of the specified CSS style sheet or rule. The first argument must be a parsed style sheet construct (See Web::CSS::Parser) containing the sheet or rule in question. The second argument must be the ID in the parsed style sheet, identifying the sheet or rule to serialize.
$string = $serializer->serialize_selectors ($selectors): Return the character string representation of the specified list of selectors. See Web::CSS::Selectors::Serializer for details.
$string = $serializer->serialize_value ($value): Return the character string representation of the specified CSS value. The argument must be a parsed representation of the CSS value. See also Web::CSS::Values.

SPECIFICATIONS

CSSOM

CSS Object Model (CSSOM) <http://dev.w3.org/csswg/cssom/>.

To "serialize a CSS component value" which is <angle>, <frequency>, <length>, or <resolution>, instead of the unit hardcoded in the spec, the original unit of the value, converted to ASCII lowercase, MUST be used.

To "serialize a CSS component value", "0" before decimal dot MUST NOT be omitted.

To "serialize a CSS rule", if the rule is a CSSMediaRule, the result of concatenating the following MUST be returned:

  1. The string "@media" followed by a U+0020 SPACE character

  2. The result of performing serialize a media query list on the
     rule's associated media list.

  3. A U+0020 SPACE character, followed by a U+007B LEFT CURLY BRACKET
     character ({), followed by a U+0020 SPACE character, followed by
     a U+000A LINE FEED character

  4. For each rule in the child CSS rules of the rule, in order,
     concatenation of the following:

     1. Two U+0020 SPACE characters

     2. The result of performing serialize a CSS rule on the rule

     3. A U+000A LINE FEED character

  5. A U+000A LINE FEED character, followed by a U+007D RIGHT CURLY
     BRACKET character (}).

To serialize a CSS style sheet, it MUST perform serialize a CSS rule on the rule in the child CSS rule of the style sheet and concatenate them in order, separated by the U+000A LINE FEED character, and return the result string.

MQ

Media Queries <http://dev.w3.org/csswg/mediaqueries/#values>.

To serialize <ratio>, optional white space MUST NOT be inserted.
