如何格式化找到替换里面循环变量 [英] How to format find-replace variables inside for loop

问题描述

我有这样的脚本：

setlocal EnableDelayedExpansion
set SECTION=dispid 3
set TARGET=pushscope
@echo on
for /F "tokens=1* delims=:" %%a in ('findstr /N /C:"%SECTION%" /C:"%TARGET%" %CHECKER%') do (
    if not defined StartSection (
        if not %%b==%%b:%SECTION%=% set StartSection=%%a
    ) else (
    goto :EOF
        if not defined TargetLine (
            goto :EOF :: Do nothing yet
            if not %%b equ !%%b:%TARGET%=! set TargetLine=%%a& goto checkercont
        )
    )
)

在StartSection（问题区域），我试图做一个查找和替换，以确认这条线就是我的愿望，并保存行号。

In StartSection (the problem area), I'm trying to do a find and replace to confirm that this line is the one I desire, and save that line number.

我如何写它，以便它将正确解析变量并做查找和替换正确？

How do I write it so that it will parse the variables correctly and do the find and replace properly?

我已经试过。 [％B]是指代替%%乙：

What I've tried. "[%b]" means the replaced %%b:

%%b:%SECTION%=% returns "[%b]:dispid 3=a" (Yes, it somehow gives me an 'a').
!%b:%SECTION%=! returns "!SECTIONa"
!%%b:%SECTION%=! returns "![%b]:dispid 3=!" (which then gives me an error saying 3 is not a command)
!%b:%SECTION%=%! returns "!SECTION!"
!%%b:!SECTION!=! returns "![%b]:!SECTION!=!"
%b:%%SECTION%%=% return "dispid 3" (and error)

我觉得像它解析大胆那么斜体最后一个。 ％B：％的 ％SECTION％的 的％=％
并使用！似乎从来没有完成，除了显示至少有一个回来给我任何东西。

I feel like for the last one that it parses the bold then the italics. %b:%%SECTION%%=% And using ! never seems to accomplish anything except display at least one back to me.

是的，我刚开始在那里乱抛垃圾一点点后（很沮丧）。

And yes, after a little bit I just started throwing random crap in there (got frustrated).

那么，什么是得到这个工作的正确方法？

So what's the proper way to get this working?

感谢

最难的类型问题SO回答的是这不工作 - 如何解决呢的问题 - 其中唯一的线索所需要的是，该OP承认不工作的构建......占卜十分什么是需要相当磨损醇'水晶球 - 和维修成本时下真是吃成蝙蝠的翅膀和蜥蜴的舌头预算...

The hardest type of question to answer on SO is the "This doesn't work - how do I fix it?" question - where the only clue to what is required is a construct that the OP admits isn't working... Divining quite what is required quite wears out the ol' crystal ball - and repair costs nowadays really eats into the bats' wings and lizards' tongues budget...

我实在想不出有什么用双反转的痴迷是一回事，无论是。为什么如果没有别的调理thingtwo thingone ??这有什么错 if条件thingone其他thingtwo ？也许我只是老式的 - 但也许它在一些荒谬的方式政治上不正确或dicriminatory

I really can't figure out what the obsession with double-inversion is all about, either. Why if not condition thingtwo else thingone ?? What's wrong with if condition thingone else thingtwo? Maybe I'm just old-fashioned - but perhaps it's politically incorrect or dicriminatory in some absurd way.

所以 - 在被检查的情况下，假设所期望的结果是确定所述第一 DISPID 3 和包含该行的行号 pushscope 该文件％检查％（在后 DISPID 3 出现其中没有样品提供...）

So - in the case under examination, assuming the desired result is to determine the linenumber of the first dispid 3 and that of the line containing pushscope that appears after the dispid 3 in the file %checker% (of which no sample is provided...)

@ECHO OFF
SETLOCAL
set SECTION=dispid 3
set TARGET=pushscope
SET checker=sourcefile.txt
SET startsection=
SET targetline=
for /F "tokens=1* delims=:" %%a in ('findstr /N /C:"%SECTION%" /C:"%TARGET%" %CHECKER%') do (
 IF DEFINED startsection (
  IF NOT DEFINED targetline (
    ECHO %%b|FIND "%target%">NUL
    IF NOT ERRORLEVEL 1 SET targetline=%%a
  )
 ) ELSE (
  ECHO %%b|FIND "%section%">NUL
  IF NOT ERRORLEVEL 1 SET startsection=%%a
 )
)

ECHO startsection=%startsection% targetline=%targetline%

GOTO :EOF

这对我的工作。情况因人而异。

Which worked for me. YMMV.
