lua 使用正则表达式分割字符串

function string_split(str, delimiter)

if str == nil or str == '' or delimiter == nil then

return nil

end

local result = {}

for match in (str..delimiter):gmatch("(.-)"..delimiter) do

table.insert(result, match)

end

return result

end

local tbl = string_split("aaaaacdddddzzzz", "c")

for k, v in pairs(tbl) do

print(k ,v )

end

输出结果：

> dofile "123.lua"

1 aaaaa

2 dddddzzzz
