Synopsis

Documentation

data NixDoc Source #

This type represents a pretty printed nix expression together with some information about the expression.

Constructors

NixDoc
Fields withoutParens :: Doc The rendered expression, without any parentheses. rootOp :: OperatorInfo The root operator is the operator at the root of the expression tree. For example, in '(a * b) + c', `+` would be the root operator. It is needed to determine if we need to wrap the expression in parentheses.

simpleExpr :: Doc -> NixDoc Source #

A simple expression is never wrapped in parentheses. The expression behaves as if its root operator had a precedence higher than all other operators (including function application).

leastPrecedence :: Doc -> NixDoc Source #

An expression that behaves as if its root operator had a precedence lower than all other operators. That ensures that the expression is wrapped in parantheses in almost always, but it's still rendered without parentheses in cases where parentheses are never required (such as in the LHS of a binding).

appOpNonAssoc :: OperatorInfo Source #

wrapParens :: OperatorInfo -> NixDoc -> Doc Source #
