lua – 将变量连接成文字字符串

我试图将变量连接成一个纯文字字符串,纯粹是出于可读性目的,例如

myString = "test"
myString2 = [[
first part of the string
this is a " .. myString .. " string
last part of the string]]
print(myString2)

但这确实是输出

first part of the string
this is a " .. myString .. " string
last part of the string

我确信它很简单,但我已经尝试使用谷歌搜索来了解如何实现这一目标并且空白.

双括号分隔符内的引号没有做任何事情.结束双支架的唯一方法是使用双支架：

myString2 = [[
first part of the string
this is a ]] .. myString .. [[ string
last part of the string]]

那会给你：

first part of the string
this is a test string
last part of the string
