log package:doctest-parallel

Basic logging function. Uses formatLogHere. Is not thread-safe.

Convenience type alias - not used in this module, but sprinkled across the project.

Prettily format a log message

threadId <- myThreadId
formatLog Debug (show threadId) "some debug message"

"[DEBUG ] [ThreadId 1277462] some debug message"

Like formatLog, but instantiates the thread argument with the current ThreadId

formatLogHere Debug "some debug message"

"[DEBUG ] [ThreadId 1440849] some debug message"

Discards any log message

Case insensitive

>>> parseLogLevel "Info"
Just Info

>>> parseLogLevel "info"
Just Info

>>> parseLogLevel "errox"
Nothing

Should a message be printed? For a given verbosity level and message log level.

Pretty print a LogLevel in a justified manner, i.e., all outputs take the same amount of characters to display.

>>> showJustifiedLogLevel Debug
"Debug  "

>>> showJustifiedLogLevel Verbose
"Verbose"

>>> showJustifiedLogLevel Info
"Info   "

>>> showJustifiedLogLevel Warning
"Warning"

>>> showJustifiedLogLevel Error
"Error  "

Verbosity level.

Parse seed argument

>>> parseLogLevel "--log-level=Debug"
Just Debug

>>> parseLogLevel "--log-level=debug"
Just Debug

>>> parseSeed "---log-level=debug"
Nothing
