如何批量拆分变量到数组

Question

我正在尝试批量编写文本冒险，所以我想知道如何拆分变量，如 set userinput=take book 并将其转换为数组。我希望能够编写一个程序，将字符串拆分为每个空间的数组项。我已经用很多其他语言做到了这一点。还有其他几个类似的问题，但我不觉得他们回答了我的问题。

Answer 1

这个任务可能比你想象的要困难得多。有很多“简单”的方法，但没有一个简单的方法是健壮的。

例如，一个简单的 FOR 循环可以解析出单个标记，但它会被

*

、

?

和可能的

"

破坏。

健壮的解决方案需要大量代码。

这是我的解决方案，有大量评论：

@echo off

:: Start out with delayed expansion disabled, and define "user input"
:: I intentionally include "problem" characters
setlocal disableDelayedExpansion
set "userinput=take book! & ;MustPreserve    EmptyLinesAreIgnored"

:: Initialize count
set "cnt=0"

:: Enable and use delayed expansion to protect against poison characters
setlocal enableDelayedExpansion

:: Substitute <LineFeed> for each <space>
(set parsed=!userinput: =^
%= Do not remove or alter this line =%
!)

:: Iterate each line, setting delims and eol to <space> to preserve all tokens
for /f "eol= delims= " %%A in ("!parsed!") do (

  %= Return to delayed expansion disabled on first iteration, else ! is lost =%
  if "!" equ "" endlocal

  %= Increment the count =%
  set /a cnt+=1

  %= Temporarily enable delayed expansion to capture current count in FOR variable =%
  setlocal enableDelayedExpansion
  for %%N in (!cnt!) do (
    endlocal

    %= Save the array value =%
    set "token.%%N=%%A"
  )
)

::Print the results. Safe array access requires delayed expansion
setlocal enableDelayedExpansion
for /l %%N in (1 1 !cnt!) do echo token.%%N=!token.%%N!

没有评论看起来好多了

@echo off
setlocal disableDelayedExpansion
set "userinput=take book! & :MustPreserveColon ;MustPreserve    EmptyLinesAreIgnored"

set "cnt=0"
setlocal enableDelayedExpansion
(set parsed=!userinput: =^
%= Do not remove or alter this line =%
!)
for /f "eol= delims= " %%A in ("!parsed!") do (
  if "!" equ "" endlocal
  set /a cnt+=1
  setlocal enableDelayedExpansion
  for %%N in (!cnt!) do (
    endlocal
    set "token.%%N=%%A"
  )
)

setlocal enableDelayedExpansion
for /l %%N in (1 1 !cnt!) do echo token.%%N=!token.%%N!

这是输出：

token.1=take
token.2=book!
token.3=&
token.4=;MustPreserve
token.5=EmptyLinesAreIgnored
