q -package:hledger-web

Combinator for the <q> element. Example:

q $ span $ toHtml "foo"

Result:

<q><span>foo</span></q>

QuasiQuoter for a non-interpolating string literal. The pattern portion is undefined.

Quadratic Bezier curve

The quotient

In short, Q provides the Quasi operations in one neat monad for the user. The longer story, is that Q wraps an arbitrary Quasi-able monad. The perceptive reader notices that Quasi has only two instances, Q itself and IO, neither of which have concrete implementations.Q plays the trick of dependency inversion, providing an abstract interface for the user which is later concretely fufilled by an concrete Quasi instance, internal to GHC.
