Description

A Verbosity type with associated utilities.

There are 4 standard verbosity levels from silent, normal, verbose up to deafening. This is used for deciding what logging messages to print.

Verbosity also is equipped with some internal settings which can be used to control at a fine granularity the verbosity of specific settings (e.g., so that you can trace only particular things you are interested in.) It's important to note that the instances for Verbosity assume that this does not exist.

Call stacks

verboseCallSite :: Verbosity -> Verbosity Source #

Turn on verbose call-site printing when we log.

verboseCallStack :: Verbosity -> Verbosity Source #

Turn on verbose call-stack printing when we log.

isVerboseCallSite :: Verbosity -> Bool Source #

Test if we should output call sites when we log.

isVerboseCallStack :: Verbosity -> Bool Source #

Test if we should output call stacks when we log.

Output markets

verboseMarkOutput :: Verbosity -> Verbosity Source #

isVerboseMarkOutput :: Verbosity -> Bool Source #

Test if we should output markets.

verboseUnmarkOutput :: Verbosity -> Verbosity Source #

Turn off marking; useful for suppressing nondeterministic output.

line-wrapping

verboseNoWrap :: Verbosity -> Verbosity Source #

Disable line-wrapping for log messages.

isVerboseNoWrap :: Verbosity -> Bool Source #

Test if line-wrapping is disabled for log messages.
