vim - 如果vim版本小于期望的目标，如何引发异常？ (.vimrc/init.vim)

Question

简而言之，在neovim / vim中都可以这样说:

if (neovim.version < 0.4.3)
  throw "Cannot run script."
endif

Answer 1

在has("nvim-x.y.z")和:h has()下都提到了h v:version:

if !has("nvim-0.4.3")
    " some error processing
    throw "Running under " . (has("nvim") ? "old Neovim" : "Vim")
endif
