Distribution.Verbosity
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.

Verbosity
moreVerbose :: Verbosity -> Verbosity #
lessVerbose :: Verbosity -> Verbosity #
isVerboseQuiet :: Verbosity -> Bool #
Test if we had called lessVerbose on the verbosity
intToVerbosity :: Int -> Maybe Verbosity #
showForCabal :: Verbosity -> String #
showForGHC :: Verbosity -> String #
verboseNoFlags :: Verbosity -> Verbosity #
verboseHasFlags :: Verbosity -> Bool #
Call stacks
verboseCallSite :: Verbosity -> Verbosity #
Turn on verbose call-site printing when we log.
verboseCallStack :: Verbosity -> Verbosity #
Turn on verbose call-stack printing when we log.
isVerboseCallSite :: Verbosity -> Bool #
Test if we should output call sites when we log.
isVerboseCallStack :: Verbosity -> Bool #
Test if we should output call stacks when we log.
Output markets
verboseMarkOutput :: Verbosity -> Verbosity #
Turn on -----BEGIN CABAL OUTPUT----- markers for output
from Cabal (as opposed to GHC, or system dependent).
isVerboseMarkOutput :: Verbosity -> Bool #
Test if we should output markets.
verboseUnmarkOutput :: Verbosity -> Verbosity #
Turn off marking; useful for suppressing nondeterministic output.
line-wrapping
verboseNoWrap :: Verbosity -> Verbosity #
Disable line-wrapping for log messages.
isVerboseNoWrap :: Verbosity -> Bool #
Test if line-wrapping is disabled for log messages.
