mkHandleScribe :: ColorStrategy -> Handle -> Severity -> Verbosity -> IO Scribe Source #
Logs to a file handle such as stdout, stderr, or a file. Contexts and other information will be flattened out into bracketed fields. For example:
[2016-05-11 21:01:15][MyApp][Info][myhost.example.com][1724][ThreadId 1154][main:Helpers.Logging Helpers/Logging.hs:32:7] Started [2016-05-11 21:01:15][MyApp.confrabulation][Debug][myhost.example.com][1724][ThreadId 1154][confrab_factor:42.0][main:Helpers.Logging Helpers/Logging.hs:41:9] Confrabulating widgets, with extra namespace and context [2016-05-11 21:01:15][MyApp][Info][myhost.example.com][1724][ThreadId 1154][main:Helpers.Logging Helpers/Logging.hs:43:7] Namespace and context are back to normal
Returns the newly-created Scribe
. The finalizer flushes the handle.
