[Haskell-beginners] Parsing keywords

Hi, What is the idiomatic way of parsing keywords, in a case agnostic fashion, for a ‘mini-language’? For example I’m creating some structured text… project{ env{ } setup{ } run{ } } that has ‘project’, ‘env’, ‘setup’ and ‘run’ as keywords and I want to parse in such a way that ‘PROJECT’, ‘ProJect’ etc are all recognised as the keyword ‘project’ similarly for ‘env’ etc. I’m using monadic rather than applicative parsing. Many Thanks Mike
