1.如何用Lua编辑.txt?
下面这段代码基本把io库都示范到了。
FileStr = “test.txt”
Hnd, ErrStr = io.open(FileStr, “w”)
if Hnd then
Hnd:setvbuf(“full”, 1024)
for K = 1, 4 do
if K == 3 then
Pos = Hnd:seek(“cur”, 0)
Hnd:write(“Special line\n”)
end
Hnd:write(string.format(“Line %02d\n”, K))
end
Hnd:flush()
Hnd:close()
Hnd, ErrStr = io.open(FileStr, “r”)
if Hnd then
for Str in Hnd:lines() do
io.write(Str, “\n”)
end
Hnd:seek(“set”, Pos)
Str = Hnd:read(“*l”)
io.write(Str, “\n”)
Hnd:close()
else
io.write(ErrStr)
end
else
io.write(ErrStr)
end
