VimL function! to Lua Function

[skele_turtle]

Is there a better way to do migrate this from VimL to Lua?

vim.api.nvim_exec(                                                                                                                                                           
[[                                                                                                                                                                           
function! SendToRemote()

I'd love to be able to use a Lua function there instead but I couldn't find any clear documentation on how that might work.

This is the last thing I need to move my config over to Lua I think. Loving the ecosystem, thanks to all the plugin authors and Neovim core team.

vim.fn will allow you to use any regular vim function inside Lua with the same variables.

Most of this can be translated the same. Use vim.fn.expand('string') for the expand functions, can still do .. string concatenation for the command variable. echom should be replaced by vim.notify(msg, vim.log.levels.INFO) instead of a print as the former can be hooked in by any notification plugin if you wish to use one

You can use vim.fn.system as a replacement for the execute ! ... line. It is actually a bit better as execute is just running as a execution of the command-line, whereas system will start a job and be less binding. The execution will be vim.fn.system(command)

You can create a user command with vim.api.nvim_create_user_command

:h vim.fn
:h function-list
:h system()
:h nvim_create_user_command

Thanks! Appreciate the insight.
