  2. Docs

Default implementation of a Handlers module.

In the DefaultHandlers module, handlers have level of their own. Their are two kinds of logger :

  • Cli handler: outputs colored messages to stdout

    let h = Default_handlers.make (Cli Debug)

  • File handler : outputs messages to a given file

    let h = Default_handlers.make (File ("filename", Debug))

Type definitions

type tag = unit

we don't use tags here

type log_item = {
  1. level : Easy_logging__.Easy_logging_types.level;
  2. logger_name : string;
  3. msg : string;
  4. tags : tag list;
}
type log_formatter = log_item -> string
type t = {
  1. mutable fmt : log_formatter;
  2. mutable level : Easy_logging__.Easy_logging_types.level;
  3. output : out_channel;
}
