[%log.debug log "example log" (content : Content.t)] [%log.global.debug "example log" (content : Content.t)]
How to add to your project
You can simply
open Async in the files that you want to log with
open Async.Ppx_log_syntax.No_global will prevent you from using
Log.Global if you want to avoid the global log.
ppx_log can add source code position to each logged message, configurable at a library level by the
(preprocess (pps (ppx_jane ... -log-source-position)))
[%log.debug] to your heart's content!
