A ppx rewriter that defines extension nodes for logging: primarily useful
to avoid the allocation of sexps that will never be logged.

[%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
Async.Log. Additionally, 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 -log-source-position switch:

(preprocess (pps (ppx_jane ... -log-source-position)))

Finally [%log.debug] to your heart's content!
