string.gfind（lua 函数）

--lua 的字符串处理把字符串按照一定的格式存到table表中

fileTable = {}

s = "from={world, to=Lua}";

for k, v in string.gfind(s, "(%w+)=(%b{})") do

print(k)

fileTable[k] = v;

print(v)

end

s = "from=world, to=Lua";

for k, v in string.gfind(s, "(%w+)=(%w+)") do

print(k)

fileTable[k] = v;

print(v)

end

string.gfind也可用string.gmatch
