How to import lua file to execute it?
I'm using Lua Mac 5.1.4 Compiler.
I'm trying to import lua file 开发者_Go百科and run it.
I tried using this code:
% lua hello.lua
But I'm getting this error: stdin:1: unexpected symbol near '%'
Am I doing something wrong? This is my first day using lua so be easy on me.
Thank you.
The problem is probably that you saw this verbatim text in a tutorial:
% lua hello.lua
The '%' at the beginning of the line is not something you are supposed to type into your terminal, but is rather a generic prompt indicator. Sometimes you might see it written as '$' instead:
$ lua hello.lua
In either case, the first character is not something you type, but rather is a typographical convention to suggest that what follows is to be typed at a prompt. Your actual prompt might look something like this:
mo@macbook$
So you would type lua hello.lua
but your screen would look like this:
mo@macbook$ lua hello.lua
So, try just entering lua hello.lua
and see what happens.
Note that the error message you got regarding stdin:1
is likely from your shell (e.g. bash), and not from Lua (which never even started running due to the malformed command in the shell).
The error stdin:1: unexpected symbol near '%'
suggests that you typed in % lua hello.lua
while in an interactive lua session (or you executed a script containing it). Now that's something that you should type in in the commandline window.
Instead try something like print'Hello World!'
Lua provides two ways to call a file. One is the loadfile() and the other is the dofile() commands. Try using dofile("hello.lua").That should work.If it doesn't type the absolute path...:)
