yasnippet有直接选择哪个模版插入的方法吗？

俺现在用的是这个

GitHub - joaotavora/yasnippet: A template system for Emacs

(yas-insert-snippet &optional NO-CONDITION)

Choose a snippet to expand, pop-up a list of choices according
to ‘yas-prompt-functions’.

最常见的应该是这个了吧，但是这会弹出一个列表让你选哪个，我想直接指定，但是这个方法好像也没有这个参数，这个NO-CONDITION只是筛选用的

然后查看所有yas有关的方法，好像没有这种方法？？

(yas-expand-snippet (yas-lookup-snippet "your-snippet"))

这两个函数都是存在的。你可能没有正常加载 yas-minor-mode。
