Concatenate mapping with zt mapping

Question

I'm using CoC and coc-python, and there is the gd mapping, which goes to the definition of a symbol. The mapping is defined as: nmap gd (doc-definition) Now, I want to first do a vsplit of the current buffer, then use the gd, and then use the zt mapping. I'm using the: nmap gd :vsplit(coc-definition)zt but the zt is never executed. I have tried using: nmap gd :vsplit(coc-definition)zt (i.w. removing the after the (coc-definition)) but it still does not work. Also, there is already the definition: nmap gd (coc-definition) and I just want to add the variation with the . Where is my error here and how will it work? Thnx!

It seems the problem is that CoC is using an asynchronous action that doesn't take affect right at the point where the mapping is executed.

Looking at the CoC sources, I see there's a CocAction() counterpart to CocActionAsync(), so maybe you can use that to run the gd action synchronously.

Try the following:

nnoremap <silent> <leader>gd :vsplit<CR>:call CocAction('jumpDefinition')<CR>zt

What about nmap gd :vsplit(coc-definition)zt ? You start in normal mode, with :vsplit you start and end command-line mode. Then just just continue with (coc-definition) and zt as normal mode mappings, no need for additional . Something or (Something) is a special mapping for plugin authors to provide convenient way of remapping without introducing default maps that might clash with what users have.
