Module `Devkit_core.Log`Source

Global ready-to-use logger

TODO interface to manage State

Example usage

Create logging facility (messages origin)

let http = Log.facility "http"

Log from http subsystem at debug level

Log.debug http "received %u bytes"

Create and use object for http logging

let log = Log.from "http" (* new Log.logger http *);;
log#info "sent %u bytes" 1024
log#warn ~exn "failed here"

Output only messages of warning level or higher for the http facility

http#allow `Warn

or

Logger.set_filter http `Warn

or

Log.set_filter ~name:"http" `Warn

or

Log.set_filter ~name:"http*" `Warn

to set for all facilities starting with "http"

Output only messages of warning level or higher for all facilities

Log.set_filter `Warn

Sourceval read_env_config : ?env:string -> unit -> unit

Update facilities configuration from the environment.

By default, it reads the configuration in the environment variable DEVKIT_LOG which can be overwritten using the optional process_name parameter.

The value of environment variable should match the following grammar: ([<facil|prefix*>=]debug|info|warn|error[,])*

raises Failure
on invalid level values of wrong format

  ?exn:exn ->

  ?saved_backtrace:string list ->
  ('a, unit, string, unit) format4 ->

param lines: whether to split multiline message as separate log lines (default true)

param backtrace: whether to show backtrace (default is true if exn is given and backtrace recording is enabled)

param saved_backtrace: supply backtrace to show instead of using Printexc.get_backtrace
