Class Method Details

.highlight(text, lexer, formatter, &b) ⇒ Object

Highlight some text with a given lexer and formatter.

Examples:

Rouge.highlight('@foo = 1', 'ruby', 'html')
Rouge.highlight('var foo = 1;', 'js', 'terminal256')

# streaming - chunks become available as they are lexed
Rouge.highlight(large_string, 'ruby', 'html') do |chunk|
  $stdout.print chunk
end
