Question

我的AutoIt脚本让用户将文本粘贴到字段中，然后单击按钮将常规单位转换为公制单位。它不仅可以转换单词，还可以转换它们之前的数字。

下面的文字是输入：

1 foot 1 inch
2 feet 2 inches
3 feet 3 inches
1 inch
2 inches
3 in
1 foot
2 feet
3 ft

这是预期的输出：

33.02 centimeters
66.04 centimeters
99.06 centimeters
2.54 centimeters
5.08 centimeters
7.62 cm  
30.48 centimeters
60.96 centimeters
91.44 cm

但这就是我得到的：

1006.4496 centimeters
2012.8992 centimeters
3019.3488 centimeters
2.54 centimeters
5.08 centimeters
7.62 cm
30.48 centimeters
60.96 centimeters
91.44 centimeters

似乎前三行乘以30.48。我不要那个。这是代码：

Case $msg = $CTRL_i
    ;For unit measurements of feet and inches
    $input_str = GUICtrlRead($Textbox)
    $WordArray = StringRegExp($input_str, "[\s\.:;,]*([a-zA-Z0-9-_]*\.?[a-zA-Z0-9-_]+)[\s\.:;,]*", 3)
    ;MsgBox($MB_OK, "Size:", UBound($WordArray))
    For $i = 0 To (UBound($WordArray) - 1) Step 1
        If (($i + 3) <= UBound($WordArray)) Then
            If (StringIsDigit($WordArray[$i]) Or StringIsFloat($WordArray[$i])) And ($WordArray[$i + 1] = "feet" Or "foot" Or "ft") And (StringIsDigit($WordArray[$i + 2]) Or StringIsFloat($WordArray[$i + 2])) And ($WordArray[$i + 3] = "inches" Or "inch" Or "in") Then

Answer 1

这种语法：

($WordArray[$i+1] = "feet" Or "foot" Or "ft")

实际上被解释为

(($WordArray[$i+1] = "feet") Or ("foot") Or ("ft"))

"foot"始终为True且"ft"始终为True，因为它们都不是空字符串。

请改用此语法：

($WordArray[$i+1] = "feet" Or $WordArray[$i+1] = "foot" Or $WordArray[$i+1] = "ft")

后者将$WordArray[$i+1]与每个字符串进行比较。

更改此类语法的所有实例，您的代码可能会按预期工作。

这有点容易出错，但它显示了一种更简单的方法。

#include <signal.h>
#include <unistd.h>
...
signal(SIGUSR1, SIG_IGN); /* Ignore own signal */

killpg(getpgrp(), SIGUSR1); /* Send SIGUSR1 to pgrp */

为什么我的脚本将值乘以30.48？
