119&emsp;Use Yuescript module in Lua:
120
121* **Case 1**
122Require "your_yuescript_entry.yue" in Lua.
118```Lua 123```Lua
119-- require `main.yue` in Lua 124require("yue")("your_yuescript_entry")
120require("yue")("main") 125```
126&emsp;And this code still works when you compile "your_yuescript_entry.yue" to "your_yuescript_entry.lua" in the same path. In the rest Yuescript files just use the normal **require** or **import**. The code line numbers in error messages will also be handled correctly.
121 127
122-- use the Yuescript compiler in Lua 128* **Case 2**
129Require Yuescript module and rewite message by hand.
130```lua
131local yue = require("yue")
132local success, result = xpcall(function()
133 yue.require("yuescript_module_name")
134end, function(err)
135 return yue.traceback(err)
136end)
137```
138
139* **Case 3**

Additionally **!=** is as an alias for **~=**, and either **\\** or **::** can be used to write a chaining function call like `tb\func!` or `tb::func!`.
