package logs

v0.9.0 2025-07-08 Zagreb

• Replace references and mutable fields by atomic references to avoid race conditions (#56). Thanks to Nathan Taylor for reporting.
• Fix Logs.{err,warn}_count. The counts were counting the reports not the logs which is not what the spec says. This means the counts were wrong when the reporting level was below the corresponding level (#55). Thanks to Mathieu Barbin for the report.
• Fix Log.Tag.list always returning the empty list.
• Logs.format_reporter and Logs_fmt.reporter replace a few format strings and ^^ uses by direct calls to Format primitives.
• Requires OCaml >= 4.14.
• Use Format.pp_print_text instead of your own.
• Export logs from each sub library.

v0.8.0 2025-03-10 La Forclaz (VS)

• Install one library per directory (#48). Thanks to @mefyl for the suggestion.
• Requires OCaml >= 4.08, Cmdliner >= 1.3.0, Fmt >= 0.9.0 and js_of_ocaml-compiler >= 5.5.0
• Depend on the js_of_ocaml-compiler.runtime library rather than js_of_ocaml.
• Handle cmdliner deprecations.

v0.7.0 2019-08-09 Zagreb

Support for thread safe logging, thanks to Jules Aguillon for the work.

• Add Logs.set_reporter_mutex for installing mutual exclusion primitives to access the reporter.
• Add Logs_threaded.enable to install mutual exclusion primitives for OCaml threads.

v0.6.3 2019-04-19 La Forclaz (VS)

• Make the package compatible with js_of_ocaml 3.3.0's namespacing. Thanks to Hugo Heuzard for the patch.
• Fix toplevel initialisation for Omod (#21).
• Fix 4.08 Pervasives deprecation.
• Drop support for ocaml < 4.03.0
• Doc: various improvements and typo fixing.

v0.6.2 2016-08-10 Zagreb

• 4.04.0 compatibility. Thanks to Damien Doligez for the patch.

v0.6.1 2016-06-08 Cambridge (UK)

v0.6.0 2016-05-23 La Forclaz (VS)

• Build depend on topkg.
• Relicensed from BSD3 to ISC.
• Revise the command line interface provided by Logs_cli. Removes the argument from option -v. See issue #13 for details.
• Add Logs.format_reporter a reporter like Logs_fmt.reporter but without colors and hence without the dependency on Fmt. Thanks to Simon Cruanes for the suggestion.
• Logs_fmt.reporter, the optional argument prefix is changed to pp_header and becomes a formatter. The default prefix now favors the basename of Sys.argv.(0) if it exists over Sys.executable_name; this gives better results for interpreted programs.
• Fix colors in Logs_fmt.pp_header, only Logs.err_style was being used.
• Add Logs.level_{of,to}_string.

v0.5.0 2016-01-07 La Forclaz (VS)

• Support for OCaml 4.01.0
• Change the logging structure from Logs.err fmt (fun m -> m ...) to Logs.err (fun m -> m fmt ...). See the documentation basics for more details. Thanks to Edwin Török for suggesting this.
• Remove the Logs.unit[_msgf] functions, they are no longer needed.
• Rename the Logs_stdo library to Logs_fmt.
• Changes the signature of reporters to take a callback function to call unconditionally once the report is over. Thanks to Edwin Török for suggesting the mecanism.
• Add the optional Logs_lwt library. Provides logging functions returning lwt threads that proceed only once the report is over.
• Add Logs_fmt.pp_header and Logs_fmt.{err_warn,info_debug}_style.
• Add Logs.pp_{level,header}.
