Ok. Nothing seems wrong at first sight, it seems I will need access to a windows machine to reproduce. Can you describe the cygwin setup? Do you have a VM...

There as been a lot of windows specific changes, see http://www.dra27.uk/blog/platform/2017/08/24/merlin-3-on-windows.html . Can you try with latest version?

I think this would be a nice improvement, even outside ocamllsp. I prefer to avoid adding a dependency on spawn, launching is already done from C code, it shouldn't be...

> Why do you think so? @rgrinberg: Sorry for the late reply. In the past, we had users that launched merlin from a directory that was sometimes deleted soon after...

Here is an example showing syntactic completion in an expression: 

TODO: Syntactic completion engine does not handle well completing when the cursor is on an existing word. Fix handling when the cursor is - [x] in the middle of a...
