I am curious about testing macvim and it seems doing fine in edit mode. But how do i set up the typesetting engine?

As far as I understand, there is, the command :ConteXt with guidance from the wiki https://wiki.contextgarden.net/Vim

But I do not understand how to customize it to be directed to the path to my engine

I’ve installed the LMTX in /Users/janneman/context-osx-64/

The installation works fine in TeXshop but still an error shows up in macvim and the message dissappears very quick so there is not much time to read the cause of error.

I have created the subdirectory .vim/ftplugin/ and put the context.vim file there

also the corresponding in .vim/compiler/context.vim 

which is copied from the program located in /usr/local/Cellar/macvim/8.2-163/MacVim.app/Contents/Resources/vim/runtime
