Constant Summary collapse

HTML_BLOCK =
TODO:

what else should be treated?

HTML tags that have end-block checks. any block starting with one of these tags will have its contents passed through until end of the tag (essentially, raw)

/^<(style|script|table|dl|select|textarea|\!--|\?)/
HTML_BLOCK_END = 
{
  '<!--' => '-->',
  '<?' => '\\?>'
}.freeze
HTML_PASSTHRU =

For lines starting with only these tags, accept as-is

/^\s*<(\/?(html|head|meta|link|title|body|br|section|div|blockquote|p|pre))/
START_TEXT = 
/^(p|bq|pre|raw|div)[(.]/
