Builds a ProcessSpec that spawns a thread that logs messages written with the returned LogFunc. Use this function when your want your logger to be part of a static supervision tree.

IMPORTANT If you use the returned LogFunc to log functions and the ProcessSpec is not used in a supervision tree, your logging won't work and your application will eventually block the current thread when logging.

A minimal example:

{--}
{--}
import RIO
import Capataz

main :: IO ()
main = do
  logOptions <- logOptionsHandle stdout True
  (loggerSpec, logFunc) <- buildLogWorkerSpec logOptions "app-logger" 100 id
  runRIO logFunc $ do
    bracket (forkCapataz "application" (set supervisorProcessSpecListL [loggerSpec]))
            terminateCapataz_ $ _capataz -> do
      logInfo "this log message is written by a dedicated supervised thread"
      threadDelay 1000100

Since: capataz-0.2.0.0

Builds a WorkerOptions record that spawns a thread that logs messages written with the returned LogFunc. Use this function if you want to build a logger thread dynamically via forkWorker.

IMPORTANT If you use the returned LogFunc to log functions and the WorkerOptions is not used in a forkWorker call, your logging won't work and your application will eventually block the current thread when logging.

A minimal example:

{--}
{--}
import RIO
import Capataz

main :: IO ()
main = do
  logOptions <- logOptionsHandle stdout True
  (loggerOptions, logFunc) <- buildLogWorkerOptions logOptions "app-logger" 100 id
  runRIO logFunc $ do
    bracket (forkCapataz "application" id)
            terminateCapataz_ $ capataz -> do
      _workerId <- forkWorker loggerOptions capataz
      logInfo "this log message is written by a dedicated supervised thread"
      threadDelay 1000100
