带连字符的 Lua string.gsub [英] Lua string.gsub with a hyphen

问题描述

我有两个字符串 - 每个字符串有很多行，如下所示:

I have two strings - each string has many lines like the following:

value_1 = "DEFAULT-VLAN"
value_2 = "WAN"
data = "HOSTNAME = DEFAULT-VLAN"
result = string.gsub(data,value_1,value_2)
print(result)

结果:

data = "HOSTNAME = DEFAULT-VLAN"

当连字符(-")从它正在工作的值中删除时.有没有简单的方法可以解决这个问题?

When the hyphen ("-") is deleted from the value it is working. Is there an easy way to solve this?

谢谢！

推荐答案

- 是 Lua 模式中的魔法字符.你需要逃避它.

- is a magic character in Lua patterns. You need to escape it.

改变

value_1 = "DEFAULT-VLAN"

到:

value_1 = "DEFAULT%-VLAN"
