Question

假设我有一个字符串，其中包含"## ##"中我想要读取的stdin形式，例如"15 16"。这很简单：

I HAS A STRINGY
GIMMEH STRINGY

从stdin获取整行并将其存储到字符串中，对不起， YARN - 称为STRINGY。

如何提取字符串中的两个整数？我希望能够存储15和16作为整数（LULZ I MEANS NUMBR）。

Answer 1

简答：

您无法在LOLCODE 1.2中执行此操作。

答案很长：

由于没有YARN操作函数，并且无法在建议的1.3规范中将YARN转换为类似BUKKIT的内容（因此我们可以将字符串模拟为{ {1}}个字符），无法从字符串中提取数字。

只使用1.2规范，我们仍然能够完成这项工作，我猜......

由于字符串连接在1.2中已经存在BUKKIT，理论上你可以保留变量SMOOSH ... MKAY到str01，然后......

str99

接下来，获取NUMBR ...

IM IN YR readloop UPPIN YR throwawayvariable WILE BOTH OF NOT broken AN DIFFRINT currentyarn AN STRINGY
    str01, WTF?
        OMG "Z"
            str99 R str98
            str98 R str97
            str97 R str96
            ...
            str02 R str01
            str01 R ""
            GTFO
        OMG "Y"
            str01 R "Z";
            GTFO
        OMG "X"
            str01 R "Y";
            GTFO
        ...
        OMG "0"
            str01 R "1";
            GTFO
        OMG ""
            str01 R "0"
            GTFO
        OMGWTF
            I HAS A ERRORMSG
            ERRORMSG R SMOOSH "I DUNNO WAT U SAY, illegal character", str01 MKAY
            VISIBLE ERRORMSG
            broken R WIN
            GTFO
    OIC
    currentyarn R SMOOSH str01, str02, str03, str04, ..., str98, str99 MKAY
IM OUTTA YR readloop

最后，你想用它们做什么。

NOT broken, O RLY? YA RLY
    yarnnumber R ""
    done R FAIL
    IM IN YR parseloop UPPIN YR otherthrowaway WILE NOT done
        EITHER OF BOTH SAEM str01 AN " " AN BOTH SAEM str01 AN "", O RLY? YA RLY
            number1 R 0
            DIFFRINT yarnnumber AN "", O RLY? YA RLY
                number1 R MAEK yarnnumber A NUMBR
            OIC
            done R WIN
        MEBBE DIFFRINT str01 AN ""
            yarnnumber R SMOOSH yarnnumber, str01 MKAY
        OIC
        str01 R str02
        str02 R str03
        str03 R str04
        ...
        str98 R str99
        str99 R ""
    IM OUTTA YR parseloop

    yarnnumber R ""
    done R FAIL
    IM IN YR parseloop2 UPPIN YR otherthrowaway2 WILE NOT done
        EITHER OF BOTH SAEM str01 AN " " AN BOTH SAEM str01 AN "", O RLY? YA RLY
            number2 R 0
            DIFFRINT yarnnumber AN "", O RLY? YA RLY
                number2 R MAEK yarnnumber A NUMBR
            OIC
            done R WIN
        MEBBE DIFFRINT str01 AN ""
            yarnnumber R SMOOSH yarnnumber, str01 MKAY
        OIC
        str01 R str02
        str02 R str03
        str03 R str04
        ...
        str98 R str99
        str99 R ""
    IM OUTTA YR parseloop2
OIC

对于I HAZ A result result R SUM OF number1 AN number2 VISIBLE result，请填写使用...变量的其余语句。

如果您要使用此功能，我建议您使用一些东西为您生成LOLCODE，手动编写这样做是不可行的。特别是如果你必须支持更长的输入行，如255或1024个字符。
