Detailed Description

A QualifiedRule has a list of component values and a block, this is the intermediate representation of a stylesheet rule.

For example, for a stylesheet rule:

a > b { color: red }

• a > b is part of the prelude, as a tokenized list of ComponentValue.
• The block contains color: red, tokenized, and an associatedToken of Token::indexOf<Token::CurlyBracket>, or <{-token}>.

operator<<

std::ostream & operator<< ( std::ostream & os, const QualifiedRule & qualifiedRule )

friend

Ostream output operator for the QualifiedRule, in a human-readable but verbose format, to be used for debugging and testing.

For example:

QualifiedRule {
  a > b { color: red }
}

Would be:

file=rule_parser_tests.cc
    QualifiedRule {
    Token { Ident(a) offset: 0 }
    Token { Whitespace(' ', len=1) offset: 1 }
    Token { Delim(>) offset: 2 }
    Token { Whitespace(' ', len=1) offset: 3 }
    Token { Ident(b) offset: 4 }
    Token { Whitespace(' ', len=1) offset: 5 }
    { SimpleBlock {
    token='{'
    Token { Whitespace(' ', len=1) offset: 7 }
    Token { Ident(color) offset: 8 }
    Token { Colon offset: 13 }
    Token { Whitespace(' ', len=1) offset: 14 }
    Token { Ident(red) offset: 15 }
    Token { Whitespace(' ', len=1) offset: 18 }
    } }
    }

Member Data Documentation

block

SimpleBlock donner::css::QualifiedRule::block

Block with an opening associated token, such as '{', '[', or '(', and a list of tokens within the block.

For stylesheet rules, this is the '{ color: red }' part of the rule.

prelude

std::vector<ComponentValue> donner::css::QualifiedRule::prelude

A list of component values before the block definition.

For a > b { color: red }, a > b is the prelude, and it would be parsed into five token ComponentValue, a, ' ', >, b, ' '.
