在选择特定选项时包括另一个 option/file

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。

有些事情是这样的：

: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%

所以基本上这是可行的。但是我需要的是一种方法，如果同时选择了 "Option 1" 和 "Option A"，则可以为我的程序包含另一个启动参数。不在 "Option 2" 和 "Option B".

中

所以我的发布看起来像这样

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

编辑：我在此命令行中犯了一些错误，但自从@avery_larry 指出以来我不会更正它。

很抱歉让我感到困惑，如果需要进一步澄清或详细说明，请告诉我。 :)

Answer 1

未测试

如果一个变量没有被设置为任何东西，那么它将展开为空。设置您的第三个变量，并确保在不满足条件时不设置它。像这样：

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。它也可能应该是：

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

最后您可能想使用 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

    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为了问题的目的而使用输入选项，而不是现实世界中的输入选项；因为它们是已知选项，所以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
