purescript-logging-journald

A drop of glue between purescript-logging and purescript-systemd-journald.

Usage

  import Control.Logger (log)
  import Control.Logger.Journald (Level(Debug, Emerg), SYSTEMD, journald, logger)
  import Control.Monad.Eff (Eff)

  main :: ∀ eff. Eff (systemd ∷ SYSTEMD | eff) Unit
  main = do
    j ← journald {}
    let l = logger j
    log l { level: Emerg, message: "first", fields: {extraInfo: "extra1"} }
    log l { level: Debug, message: "second", fields: {extraInfo: "extra2"} }

There is also logger' shortcut if you want to work in the given monad:

  l' ← logger' (journald {})

You can provide extra fields (through fields attribute) - purescript-systemd-journald accepts nearly anything there. For more info please consult its docs.

Log levels

There are Ord and Eq instances provided for Level type so you can do filtering like cfilter (\e → e.level > Warning).
