Batch file to add git branch into header file

问题

I'm working on a C project, under git, and I would like to add the branch name into an header file.

This is my idea:

I have a version header file:

/* Define to prevent recursive inclusion -------------------------------------*/ 
#ifndef _VERSION_INTERFACE_H_
#define _VERSION_INTERFACE_H_
/* Includes ------------------------------------------------------------------*/
/* Exported defines ----------------------------------------------------------*/
/* Exported types ------------------------------------------------------------*/
/* Exported constants --------------------------------------------------------*/
const char *gitBranch = "develop";
/* Exported macro ------------------------------------------------------------*/
/* Exported functions --------------------------------------------------------*/ 
#endif  /* _VERSION_INTERFACE_H_ */

and I would like to replace the string associated to gitBranch with the name of the current branch. In this way I can execute the batch file during the pre-build process and update the gitBranch variable.

I write a first version of a batch file:

@echo off
setlocal enabledelayedexpansion

SET GIT_CMD="C:\Program Files\Git\bin\git.exe"

rem Specify input file name
SET inputFileName=include\version_interface.h

rem String to find
SET stringToFind=const char *gitBranch

FOR /F "tokens=*" %%a in ( '"C:\Program Files\Git\bin\git.exe" branch --show-current' ) do SET branchName=%%a

rem String to replace
SET stringToReplace=%branchName%

for /F "tokens=*" %%n in (!infile!) do (
SET LINE=%%n
SET TMPR=!LINE:%stringToFind%=%stringToReplace%!
Echo !TMPR!>>tmp.txt
)

move tmp.txt %infile%
pause

but at the moment I cannot:

Update the branch name inside the header file.

Any suggestion?

Thanks in advance for the help!

Best regards, Federico

Untested. Just make sure you add the correct file path to set infile=

@echo off
set "infile=C:\Path\to\FILE.h"
for /f "tokens=*" %%a in ('"C:\Program Files\Git\bin\git.exe" branch --show-current' ) do set "branchName=%%a"
for /f "delims=" %%i in ('type "%infile%" ^| find /v /n "" ^& break^>%infile%') do (
    setlocal enabledelayedexpansion
    set "line=%%i"
    set "line=!line:*]=!"
    if "!line:~0,21!" == "const char *gitBranch" set "line=const char *gitBranch ="%branchName%";"
    echo(!line!>>!infile!
    endlocal
 )
