Re: Access vim command from the lua end WAS: How do the default key commands work
It's not about remapping. I'm writing a vimscript in lua. In a function I need
the position of the opening and closing bracket. So in vim I would execute »%«
twice. Than I have both positions. If there would be functions for the basic
comands I just would execute the corresponding function. But apparently this
is not the case.
So I rephrase my question. How to access basic vim commands (here: %) from
inside lua? How to access an arbitrary vim function from inside lua?
Use the :normal command (probably with ! to avoid using user mappings).
E.g.
:lua vim.command"normal! %"
Then to get the cursor position, you can use the getpos() function. E.g.
:lua mypos = vim.eval"getpos('.')"
Or something like that (I don't know Lua, and don't have the interface
compiled in, so haven't tested; but this is the idea).
Smiles,
Ben.
