lua - 将变量连接成文字字符串

Question

我试图纯粹出于可读性目的将变量连接成文字字符串，例如

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

但这从字面上输出

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

我确定这很简单，但我已经尝试使用谷歌搜索来找出如何实现这一目标，但结果却是空白。

Answer 1

双括号分隔符内的引号没有做任何事情。结束双括号的唯一方法是使用双括号:

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

这会给你:

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