type PrecedenceStack = [Precedence] Source #

When printing we keep track of a stack of precedences in order to be able to decide whether it's safe to leave out parens around lambdas. An empty stack is equivalent to TopCtx. Invariant: `notElem TopCtx`.

pushPrecedence :: Precedence -> PrecedenceStack -> PrecedenceStack Source #

headPrecedence :: PrecedenceStack -> Precedence Source #

argumentCtx_ :: Precedence Source #

Argument context preferring parens.

opBrackets :: Fixity -> PrecedenceStack -> Bool Source #

Do we need to bracket an operator application of the given fixity in a context with the given precedence.

opBrackets' :: Bool -> Fixity -> PrecedenceStack -> Bool Source #

Do we need to bracket an operator application of the given fixity in a context with the given precedence.

lamBrackets :: PrecedenceStack -> Bool Source #

Does a lambda-like thing (lambda, let or pi) need brackets in the given context? A peculiar thing with lambdas is that they don't need brackets in certain right operand contexts. To decide we need to look at the stack of precedences and not just the current precedence. Example: m₁ >>= (λ x → x) >>= m₂ (for _>>=_ left associative).

appBrackets :: PrecedenceStack -> Bool Source #

Does a function application need brackets?

appBrackets' :: Bool -> PrecedenceStack -> Bool Source #

Does a function application need brackets?

withAppBrackets :: PrecedenceStack -> Bool Source #

Does a with application need brackets?

piBrackets :: PrecedenceStack -> Bool Source #

Does a function space need brackets?

roundFixBrackets :: PrecedenceStack -> Bool Source #
