+
+Hi everyone!
+
+A little while ago, I [posted](https://discuss.ocaml.org/t/cmdlang-yet-another-cli-library-well-not-really/15258) about [cmdlang](https://github.com/mbarbin/cmdlang), a library for creating command-line parsers in OCaml.
+
+Today, I am happy to give you an update on this project with the announcement of an initial release of cmdlang packages to the opam-repository.
+
+These are very early days for this project. I have started using the `cmdlang+cmdliner` combination in personal projects, and plan to experiment with `climate` in the near future. Please feel free to engage in issues/discussions, etc.
+

+
+The most recent addition on the project is the development of an evaluation engine based on `stdlib/arg`.
+
+I'd also like to highlight some examples from the project's tests. Developing these characterization tests was a fun way to learn more about the different CLI libraries and their differences:
+
+- Short, long and prefix [flag names](https://github.com/mbarbin/cmdlang/blob/main/test/expect/test__flag.ml).
+
+- Various syntaxes for [named arguments](https://github.com/mbarbin/cmdlang/blob/main/test/expect/test__named.ml) (`-pVALUE`, `-p=VALUE`, `-p VALUE`).
+
+- Handling of [negative integers](https://github.com/mbarbin/cmdlang/blob/main/test/expect/test__negative_int_args.ml) as named arguments.
+
+If you have ideas for more cases to add (entertaining or otherwise), I'd love to integrate them into the test suite. Thanks!
+
+Below, you'll find details of the released packages. Happy command parsing!
+
+**cmdlang** the user facing library to build the commands. It has no dependencies
+
+**cmdlang-to-cmdliner** translate cmdlang commands to cmdliner
+
+**cmdlang-to-climate** translate cmdlang commands to the newly released climate (compatibility checked with 0.1.0 & 0.2.0)
+
+**cmdlang-stdlib-runner** an execution engine implemented on top of stdlib.arg
+
+Thank you to @mseri and the opam-repository maintainers for their help.
