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

问题描述

我有两个字符串-每个字符串都有很多行，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"

从值中删除连字符(-")时，它正在起作用. 有一种简单的方法可以解决这个问题吗?

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

谢谢！

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

更改

value_1 = "DEFAULT-VLAN"

收件人:

value_1 = "DEFAULT%-VLAN"
