讓 Markdown-On-Save-Improved 支援 Github 的 Fenced code blocks

Log — Tags: github, Markdown, WordPress — Posted by Starck on March 30, 2013

修改 markdown-on-save.php:

protected function process( $content, $id ) {
  $this->maybe_load_markdown();
  // Links with "quoted titles" bork without stripping slashes.
  // Stripslashes would lose desired backslashes. So, regex.
  $content = preg_replace( '/\\\"/', '"', $content );
  
  // Added by Starck Lin - parsing Github Fenced code blocks
  $content = preg_replace("/\n```([A-z :]+)([^```]+?)\n```/", '<pre class="lang:$1">$2</pre>', $content );
  $content = preg_replace("/\n```([^```]+?)\n```/", '<pre>$1</pre>;', $content );
  
  // convert to Markdown
  $content = $this->parser->transform( $content );
  
  // reference the post_id to make footnote ids unique
  $content = preg_replace( '/fn(ref)?:/', "fn$1-$id:", $content );
  
  return $content;
}

protected function process( $content, $id ) {

$this->maybe_load_markdown();

// Links with "quoted titles" bork without stripping slashes.

// Stripslashes would lose desired backslashes. So, regex.

$content = preg_replace( '/\\\"/', '"', $content );

// Added by Starck Lin - parsing Github Fenced code blocks

$content = preg_replace("/\n```([A-z :]+)([^```]+?)\n```/", '<pre class="lang:$1">$2</pre>', $content );

$content = preg_replace("/\n```([^```]+?)\n```/", '<pre>$1</pre>;', $content );

// convert to Markdown

$content = $this->parser->transform( $content );

// reference the post_id to make footnote ids unique

$content = preg_replace( '/fn(ref)?:/', "fn$1-$id:", $content );

return $content;

}

這是搭配 Crayon WP-Plugin, 如果遇到原始碼有 </pre> 的問題, 可以轉成 < (<) 和 > (>), 再把 crayon 的 decode 設為 true.

另外有個值得注意的點, 換行符號我是用雙引號來轉換 \n
