TH logging
Generates a function that takes a Text and logs a LevelDebug message. Usage:
$(logDebug) "This is a debug log message"
logOther :: Text -> Q ExpSource
Generates a function that takes a Text and logs a LevelOther message. Usage:
$(logOther "My new level") "This is a log message"
TH logging with source
Generates a function that takes a LogSource and Text and logs a LevelDebug message. Usage:
$logDebug "SomeSource" "This is a debug log message"
