CSS-Module-CSS3-Selectors-raku

This module extends CSS::Grammar::CSS3, to implement parsing for CSS Selectors Module Level 3. It provides grammar CSS::Module::CSS3::Selectors and actions class CSS::Module::CSS3::Selectors::Actions.

Example

use CSS::Module::CSS3::Selectors;
my $actions = CSS::Module::CSS3::Selectors::Actions.new;
CSS::Module::CSS3::Selectors.parse('tr:nth-child(2n+1) span[class="example"]', :rule<selectors>, :$actions);
say $/.ast.perl;

Some of the key extensions are:

• namespaces: svg|circle

• attribute selections: span[class="example"]

• structural selectors: tr:nth-child(2n+1) foo:nth-last-child(odd)

• negation: body > h2:not(:first-of-type):not(:last-of-type)
