  • まさに求めていたもの

    クラシックテーマからブロックテーマに移行したとき「また Prism.js の設定か。これだけのために子テーマを作るのか...。面倒だ」と思っていた中，これを見つけた。自分で用意した prism.js, prism.css を使える仕組みが備わっている点が素晴らしい。 改善されるとよい点：Shift+矢印キー でサイドバーが反応してしまう。テキスト編集領域にフォーカスが当たってほしい

  • No support for Android syntax

    Unfortunately, the plugin doesn't support Java, Kotlin, Flutter nor XML syntax, making it completely useless for anyone in the Android development field.

  • A+ Once I figured out the BLOCKS part!

    I don't normally use WP Blocks and so I could not figure out why this plugin broke for certain code syntax (PHP -> HTML -> PHP for example) and why saving sometimes broke the previously-saved syntax. Maddening. Then I switched back to the block editor. AHA! It works beautifully. That's probably why it says "Block" in the plugin name, duh. Thank you very much for this wonderful plugin. I love that we can also upload our own prism.js files. Cool.
