<kartoffelbrei.mit.muskatnuss@gmail.org>\nDescription: Ada is a general-purpose programming language that has great support for saftey critical and real-time applications.\n It has been developed by the DoD and thus has been used in military and safety-critical applications (like civil aviation).\n The first version appeared in the 80s, but it's still actively developed today with\n the newest standard being Ada2012.\n*/\n\n// We try to support full Ada2012\n//\n// We highlight all appearances of types, keywords, literals (string, char, number, bool)\n// and titles (user defined function/procedure/package)\n// CSS classes are set accordingly\n//\n// Languages causing problems for language detection:\n// xml (broken by Foo : Bar type), elm (broken by Foo : Bar type), vbscript-html (broken by body keyword)\n// sql (ada default.txt has a lot of sql keywords)\n\n/** @type LanguageFn */\nfunction ada(hljs) {\n // Regular expression for Ada numeric literals.\n //
