Module CPM.ErrorLogger

logLevelOf :: LogEntry -> LogLevel   

Further infos:

• solution complete, i.e., able to compute all solutions

getLogLevel :: IO LogLevel   

Gets the global log level. Messages below this level will not be printed.

setLogLevel :: LogLevel -> IO ()   

Sets the global log level. Messages below this level will not be printed.

setWithShowTime :: Bool -> IO ()   

Sets the "show time" information. If true, then timing information will be shown with every log information.

fromELM :: ErrorLoggerIO a -> IO ([LogEntry],Either LogEntry a)   

Transforms an ErrorLoggerIO monad action into an IO action.

Further infos:

• solution complete, i.e., able to compute all solutions

toELM :: IO ([LogEntry],Either LogEntry a) -> ErrorLoggerIO a   

Transforms an IO action into an ErrorLoggerIO monad action.

Further infos:

• solution complete, i.e., able to compute all solutions

execIO :: IO a -> ErrorLoggerIO a   

Executes an IO action in the ErrorLoggerIO monad.

putStrELM :: String -> ErrorLoggerIO ()   

Prints a string in the ErrorLoggerIO monad.

putStrLnELM :: String -> ErrorLoggerIO ()   

Prints a line in the ErrorLoggerIO monad.

runELM :: ErrorLoggerIO a -> IO a   

Runs an ErrorLoggerIO monad action as an IO action. Shows all messages and exit with status 1 if an error occurred.

(|>=) :: IO ([LogEntry],Either LogEntry a) -> (a -> IO ([LogEntry],Either LogEntry b)) -> IO ([LogEntry],Either LogEntry b)   

Further infos:

• defined as left-associative infix operator with precedence 0

(|>) :: IO ([LogEntry],Either LogEntry a) -> IO ([LogEntry],Either LogEntry b) -> IO ([LogEntry],Either LogEntry b)   

Chains two actions ignoring the result of the first.

Further infos:

• defined as left-associative infix operator with precedence 0

mapEL :: (a -> IO ([LogEntry],Either LogEntry b)) -> [a] -> IO ([LogEntry],Either LogEntry [b])   

Maps an action over a list of values. Fails if one of the actions fails.

foldEL :: (a -> b -> IO ([LogEntry],Either LogEntry a)) -> a -> [b] -> IO ([LogEntry],Either LogEntry a)   

Folds a list of values using an action. Fails if one of the actions fails.

showLogEntry :: LogEntry -> IO ()   

Renders a log entry to stderr.

levelGte :: LogLevel -> LogLevel -> Bool   

Compares two log levels.

Further infos:

• solution complete, i.e., able to compute all solutions

succeedIO :: a -> IO ([LogEntry],Either LogEntry a)   

Create an IO action that always succeeds.

failIO :: String -> IO ([LogEntry],Either LogEntry a)   

Create an IO action that always fails.

failELM :: String -> ErrorLoggerIO a   

Create an ErrorLoggerIO action that always fails with a message.

logMsg :: LogLevel -> String -> ErrorLoggerIO ()   

Creates an IO action that logs a message.

log :: LogLevel -> String -> IO ([LogEntry],Either LogEntry ())   

Creates an IO action that logs a message.

infoMessage :: String -> IO ()   

Prints an info message in the standard IO monad.

debugMessage :: String -> IO ()   

Prints a debug message in the standard IO monad.

errorMessage :: String -> IO ()   

Prints an error message in the standard IO monad.

fromErrorLogger :: IO ([LogEntry],Either LogEntry a) -> IO a   

Transforms an error logger action into a standard IO action. It shows all messages and, if the result is not available, exits with a non-zero code.

showExecCmd :: String -> IO Int   

Executes a system command and show the command as debug message.

execQuietCmd :: (String -> String) -> IO Int   

Executes a parameterized system command. The parameter is set to -q unless the LogLevel is Debug.
