Dear OCaml hackers, I’m proud to announce a preview release of an [VSC extension for OCaml](https://github.com/ocamllabs/vscode-ocaml-platform). You can fetch and install this plugin directly from the extension marketplace if you search for “OCaml Labs”. The extension isn’t yet mature, but I believe that it offers a user experience comparable to other VSC extensions for OCaml already. The plugin should be used in conjunction with [ocaml-lsp](https://github.com/ocaml/ocaml-lsp) The extension is for the OCaml “platform”, which means that its scope includes support for various tools used in OCaml development such as dune, opam. Bug reports & contributions are welcome. Happy hacking. ---

Just wanted to mention that it’s a little odd that there’s a second “OCaml Platform” package for vs-code, from different sources: [https://marketplace.visualstudio.com/items?itemName=ocamllabs.ocaml-platform](https://marketplace.visualstudio.com/items?itemName=ocamllabs.ocaml-platform) [https://marketplace.visualstudio.com/items?itemName=rustykey.href-secret-extension](https://marketplace.visualstudio.com/items?itemName=rustykey.href-secret-extension) Which one is the right one? The “RustyKey” one seems less likely to be right, but it’s a bit confusing. y ---

Nice! How does it compare with Darren Morrison’s “[Ocaml and Reason IDE](https://marketplace.visualstudio.com/items?itemName=freebroccolo.reasonml)” plugin (augmented with the “[Ocaml mll and mly](https://marketplace.visualstudio.com/items?itemName=mnxn.ocaml-mll-mly)” plugin to avoid scrambling Ocamllex and Menhir files), feature-wise? ---

So cool, just tried it on my Win 10 machine: 1. open cygwin shell 2. opam pin & install ocaml-lsp-server 3. start vscode in cygwin shell, e.g., `code .` 4. install extension in vscode You made my day! 😃
