Lua编程示例(一):select、debug、可变参数、table操作、error的介绍
function test_print(...) for i=1,select("#",...) do print(i,select(i,...)) end end test_print(11,12,13,14) print() print(debug.traceback()) print() function test(...) for i=1,arg.n do print(i.."\t"..arg[i]) end end test("a",2,34,234) print() g={} table.insert(g,{ name="Clairs", level = 70, }) table.insert(g,{ name="SEGA", level = 35, }) table.insert(g,{ name="Millber", level = 50, }) function myprint() for i,v in ipairs(g) do print(i,v["level"],v.name) end end myprint() function comp(a,b) return a.level<b.level end table.sort(g,comp) print() myprint() print() function foo(str) if type(str) ~= "string" then error("string error!",2) end end --foo({x =1 }) tb1={ "asdf","bate","game",one="heihei"} table.insert(tb1,3,"haha") table.remove(tb1,2) for i,v in ipairs(tb1) do print(v) end print(#tb1)
运行结果为:
1 11 12 13 14 2 12 13 14 3 13 14 4 14 stack traceback: my_test.lua:12: in main chunk [C]: ? 1 a 2 2 3 34 4 234 1 70 Clairs 2 35 SEGA 3 50 Millber 1 35 SEGA 2 50 Millber 3 70 Clairs asdf haha game 3
