lua - Opening Lua Files in Interactive Mode

Question

I am beginning to learn Lua on my own with basically no prior programming knowledge. I understand the basics of types, functions, tables, etc. But in following the Lua tuts at Lua.org, I'm currently on the "Modules Tutorial" and am having issues understanding the proper/easiest way to call a file made into interactive mode.

If I used Notepad++ or Scite to create a file, can someone please help me understand how to open said file using the proper nomenclature to open it?

Answer 1

假设你的文件名为foo.lua，那么在 Lua 解释器（即交互模式）中，使用loadfile. 请注意，loadfile这不会引发错误，因此最好assert与它一起使用。

f = assert(loadfile("foo.lua"))

它会将块加载foo.lua到函数f中。请注意，这只会加载块，而不是运行它。要运行它，请调用函数：

f()

如果您需要立即运行它，您可以使用dofile：

dofile("foo.lua") 

Luapackage.path用作搜索路径，其默认值来自LUA_PATH. 但是，在实践中最好使用正确的相对路径。
