Logs — Logging infrastructure for OCaml

%%VERSION%%

Logs provides a logging infrastructure for OCaml. Logging is performed on sources whose reporting level can be set independently. Log message report is decoupled from logging and is handled by a reporter.

A few optional log reporters are distributed with the base library and the API easily allows to implement your own.

Logs has no dependencies. The optional Logs_fmt reporter on OCaml formatters depends on Fmt. The optional Logs_browser reporter that reports to the web browser console depends on js_of_ocaml. The optional Logs_cli library that provides command line support for controlling Logs depends on Cmdliner. The optional Logs_lwt library that provides Lwt logging functions depends on Lwt

Logs and its reporters are distributed under the ISC license.
