Lua自己实现string.split功能
---@field TableAux table转字符串的辅助类
local TableAux = require("TableAux")
---拆分字符串
---@param str string 被拆分的源字符串
---@param sep string 拆分的
function string.split(str, sep)
local result = {}
if str == nil or sep == nil or type(str) ~= "string" or type(sep) ~= "string" then
return result
end
if string.len(sep) == 0 then
return result
end
local pattern = string.format("([^%s]+)", sep)
--print(pattern)
string.gsub(
str,
pattern,
function(c)
result[#result + 1] = c
end
)
return result
end
local strres = "112||s|22s2"
local arr = string.split(strres, "|")
print(TableAux.TableToString(arr))
输出结果:
{
[1] = "112",
[2] = "s",
[3] = "22s2",
}
