在选择特定选项时包含另一个选项/文件

Question

我制作了一个简单的批处理文件，通过启动时提供的一些选项来执行可执行文件。

类似这样的事情：

:A
Echo Option 1
Echo Option 2
Set /p set1=Choice :
if %set1%==1 set A=Set1_1
if %set1%==2 set A=Set1_2
goto Set_2

:B
Echo Option A
Echo Option B
Set /p set2=Choice :
if %set2%==A set B=Set2_A
if %set2%==B set B=Set2_B
goto launch

:launch
program.exe -%A% -%B%

所以基本上这行得通。但是，如果同时选择了“选项 1”和“选项 A”，我需要一种方法来为我的程序包含另一个启动参数。不在“选项 2”和“选项 B”中。

让我的发布看起来像这样

program.exe -%set1% -%set2% -%if1_A%

编辑：我在这个命令行上犯了一些错误，但我不会更正它，因为@avery_larry 指出了它。

很抱歉，如果我让这变得混乱，请让我知道是否需要进一步澄清或详细说明。 :)

Answer 1

未经测试

如果一个变量没有被设置为任何值，那么它将扩展为空。设置你的第三个变量，如果条件不满足，确保它没有被设置。像这样的：

set if1_a=
if "%set1%"=="1" (
   if "%set2%"=="A" (
      set "if1_a=-option"
   )
)

program.exe -%set1% -%set2% %if1_A%

请注意，我将连字符作为变量的一部分。也应该是：

program.exe -%A% -%B% %if1_A%

最后你可能想使用if /i 使其不区分大小写。

可以通过使用输入验证函数来避免用户输入问题，如下所示：

@Echo off & CD "%~dp0"
TITLE %~n0 & Setlocal

    For /F "tokens=2 delims=#" %%a in ('"prompt #$H#$E# & echo on & for %%b in (1) do rem"') do (
        Endlocal
        Set "/AE=%%a"
    )

Answer 3

虽然您的问题可能只是出于问题的目的使用输入选项，而不是现实世界的；由于它们是已知选项，因此我决定提供一个使用更强大的内置 choice.exe 命令的解决方案：

@Rem Undefine any existing variables to be used.
@For /F "Delims==" %%G In ('Set Opt[ 2^>NUL')Do @Set "%%G="

@Rem Request first argument.
@"%__APPDIR__%choice.exe" /C 12 /M "First argument"

@Rem Define the first argument with the value chosen.
@Set "Opt[1]=%ERRORLEVEL%"

@Rem Request second argument.
@"%__APPDIR__%choice.exe" /C AB /M "Second argument"

@Rem Define the second argument with the value chosen.
@If ErrorLevel 2 (Set "Opt[2]=B")Else (Set "Opt[2]=A"
    Rem Define third argument if first chosen was 1
    If %Opt[1]% Equ 1 Set "Opt[3]=-"Third option string"")

@Rem Launch program with required options.
@Echo program.exe -"%Opt[1]%" -"%Opt[2]%" %Opt[3]%

@Rem Prevent cmd window from possibly closing early.
@Pause
