The monadloc package

[Tags:library, public-domain]

This package defines a class for monads which can keep a monadic call trace.

. See for more information.

A preprocessor is provided which can insert calls to withLoc before every monadic statement in a module.

To invoke the preprocessor, add the following pragma at the top of a source file:

> -# OPTIONS_GHC -F -pgmF MonadLoc #-

together with an import for the @Control.Monad.Loc@ module

This package provides no implementation of the MonadLoc interface. Currently the only package that does so is "control-monad-exception", but any other package can implement it and provide monadic call traces.
