# Effect.Logging.Category

A logging effect that allows messages to be logged using both
numerical levels and user specified categories. The higher the
logging level the grater in verbosity the logging.

In this effect the resource we are computing over is the logging
level itself and the list of categories to show.

LOG : (a : Type) -> EFFECT

  The Logging effect.

  a

    The type used to differentiate categories.

record LogRes a

  The Logging details, this is the resource that the effect is
  defined over.

  a
  MkLogRes : (getLevel : LogLevel n) -> (getCategories : List a) -> LogRes a
  getLevel : (rec : LogRes a) -> LogLevel (free_n rec)
  getCategories : (rec : LogRes a) -> List a
data Logging : Effect

  A Logging effect to log levels and categories.

  Log : Show a => Eq a => (lvl : LogLevel n) -> (cats : List a) -> (msg : String) -> sig Logging () (LogRes a)

    Log a message.

    lvl

      The logging level it should appear at.

    cats

      The categories it should appear under.

    msg

      The message to log.

  SetLogLvl : Show a => Eq a => (nlvl : LogLevel n) -> sig Logging () (LogRes a) (LogRes a)

    Change the logging level.

    nlvl

      The new logging level

  SetLogCats : Show a => Eq a => (ncats : List a) -> sig Logging () (LogRes a) (LogRes a)

    Change the categories to show.

    ncats

      The new categories.

  InitLogger : Show a => Eq a => (nlvl : LogLevel n) -> (ncats : List a) -> sig Logging () (LogRes a) (LogRes a)

    Initialise the logging.

    nlvl

      The new logging level.

    ncats

      The categories to show.

info : Show a => Eq a => List a -> String -> Eff () [LOG a]
initLogger : Show a => Eq a => (l : LogLevel n) -> (cs : List a) -> Eff () [LOG a]

  Initialise the Logger.

  l

    The logging level.

  cs

log : Show a => Eq a => (l : LogLevel n) -> (cs : List a) -> (m : String) -> Eff () [LOG a]

  Log the given message at the given level indicated by a natural number and assign it the list of categories.

  l

    The logging level.

  cs

    The logging categories.

  m

logN : Show a => Eq a => (l : Nat) -> {auto prf : LTE l (fromInteger 70)} -> (cs : List a) -> (m : String) -> Eff () [LOG a]

  Log the given message at the given level indicated by a natural number and assign it the list of categories.

  l

    The logging level.

  cs

    The logging categories.

  m

    The message to be logged.

setLogCats : Show a => Eq a => (cs : List a) -> Eff () [LOG a]

  Change the categories to show.

  cs

    The new categories.

setLoglvl : Show a => Eq a => (l : LogLevel n) -> Eff () [LOG a]

  Change the logging level.
