runLogProgress :: Verbosity -> LogProgress a -> NoCallStackIO a Source #
Run LogProgress, outputting traces according to Verbosity,
die if there is an error.
warnProgress :: Doc -> LogProgress () Source #
Output a warning trace message in LogProgress.
infoProgress :: Doc -> LogProgress () Source #
Output an informational trace message in LogProgress.
dieProgress :: Doc -> LogProgress a Source #
Fail the computation with an error message.
addProgressCtx :: CtxMsg -> LogProgress a -> LogProgress a Source #
Add a message to the error/warning context.
