Relacionado a issue #1:
Cria extensão de pós-processamento do asciidoctor que, por meio de regex, adiciona a string
loading="lazy"a cada tag<img>logo após a geração do arquivo HTML.A extensão é adicionado junto ao comando de geração do arquivo HTML em
build.sh.Para que o lazy loading funcione é necessário que as imagens tenham suas origens definidas por links/caminhos. Logo o atributo global
:data:uri:teve que ser removido do arquivolivro.adoc.Vale notar que eu não tive experiência com a linguagem ruby anteriormente. Aprendi o básico da linguagem no rápido tutorial oficial da linguagem e em outras fontes.
