You may take interest on using either #'shell-command or #'shell-command-on-region, the version with args of the last replaces inpur region with output. Also #'mark-whole-buffer may be of interest

Thank you. In the end, I figured out that my problem wasn't exactly native to emacs, but rather how to tell eglot or ocaml-lsp where to find the ocamlformat binary – by updating PATH before launching emacs from terminal.

May be there is a better, emacs-native way to update PATH per project?

Maybe you can make a wrapper function on this command taking the buffer as input and replacing buffer content with command output and set the for that

Update: solved the ocamlformat issue. All details here: https://discuss.ocaml.org/t/ann-dune-developer-preview-updates/15160/62

All eglot does is send a formatting request to ocamllsp because ocamllsp claims to provide formatting capabilities. The onus of finding ocamlformat is on ocamllsp, which looks for ocamlformat binary on PATH >>

I didn't find a "proper" way (like a command line argument) to pass the path of ocamlformat to ocamllsp. So updating PATH it is.

# from terminal
$ PATH="$(dirname $(dune tools which ocamlformat)):$PATH" emacs

I would appreciate a better approach than this.
