WebquoteFile takes a QuasiQuoter and lifts it into one that read the data out of a file. For example, suppose asmq is an assembly-language quoter, so that you can write [asmq ld r1, r2 ] as an expression. Then if you define asmq_f = quoteFile asmq, then the quote [asmq_f foo.s ] will take input from file "foo.s" instead of the inline text. WebHaskell has a neat trick with operators: you can take any function that takes two arguments and use it like an operator by enclosing the name in back-ticks. So the following two lines …

WebJan 26, 2024 · Because "where" blocks are bound to a syntactic construct, they can be used to share bindings between parts of a function that are not syntactically expressions. For example: f x cond1 x = a cond2 x = g a otherwise = f (h x a) where a = w x. In expression style, you might use an explicit case : f x = let a = w x in case () of _ cond1 x ... Webfix f is the least fixed point of the function f, i.e. the least defined x such that f x = x.. For example, we can write the factorial function using direct recursion as >>> let fac n = if n … ardis badger
