Windows命令行在括号之间查找并替换（repl.bat）

Question

I have a variable DATE, which contains something like 06092017 I have a file with the following line:

#define BUILDDATE (05092017)

where the value between the brackets changes

I'm trying to use this to find and replace the text:

type "file.h"|repl "(#define BUILDDATE \().*?(\))" "$1%DATE%$2" >"file_new.h"

But nothing has changed in file_new.h . What am I doing wrong please? Or is there a better way?

Answer 1

Why use a external script at all?

@echo off

REM Prepare example to make batch file self-contained (this will overwrite file.h!)
echo.#define whatever              > file.h
echo.#define BUILDDATE (05092017) >> file.h
echo.#define something (1234)     >> file.h

for /F "usebackq tokens=1,2,*" %%A in (`type "file.h"`) do @if "%%~A"=="#define" if "%%~B"=="BUILDDATE" (
    for /F "tokens=1 delims=() " %%X in ("%%~C") do (
        echo.%%X > "file_new.h"
    )
)

echo Result:
type "file_new.h"

Thanks guys. Just noticed that in my file.h, there was a tab between BUILDDATE and the brackets rather than a space that was causing it to fail.
