批处理文件修改NSIS安装程序的文本文件

Question

As part of an NSIS script builder I have a list of filenames that are currently in a file called files.txt. An example of the content is below...

c:\myfolder\assets\startup.xml
c:\myfolder\assets\begin.exe
c:\myfolder\assets\begin.swf
c:\myfolder\assets\resources\assets\text\help.pdf
c:\myfolder\assets\resources\assets\text\license.rtf
c:\myfolder\assets\resources\assets\swf\piano.swf
c:\myfolder\assets\resources\assets\swf\numbers.swf
c:\myfolder\assets\resources\section1\resource1\item1.jpg
c:\myfolder\assets\resources\section1\resource1\item2.jpg
c:\myfolder\assets\resources\section4\resource1\item7.jpg
c:\myfolder\assets\resources\section4\resource1\item8.jpg

I am trying to process this list of files using a batch file so that they end up looking like this...

SetOutPath "$INSTDIR"
File "c:\myfolder\assets\startup.xml"
SetOutPath "$INSTDIR"
File "c:\myfolder\assets\begin.exe"
SetOutPath "$INSTDIR"
File "c:\myfolder\assets\begin.swf"
SetOutPath "$INSTDIR\resources\assets\text"
File "c:\myfolder\assets\resources\assets\text\help.pdf"
SetOutPath "$INSTDIR\resources\assets\text"
File "c:\myfolder\assets\resources\assets\text\license.rtf"
SetOutPath "$INSTDIR\resources\assets\swf"
File "c:\myfolder\assets\resources\assets\swf\piano.swf"
SetOutPath "$INSTDIR\resources\assets\swf"
File "c:\myfolder\assets\resources\assets\swf\numbers.swf"
SetOutPath "$INSTDIR\resources\section1\resource1"
File "c:\myfolder\assets\resources\section1\resource1\item1.jpg"
SetOutPath "$INSTDIR\resources\section1\resource1"
File "c:\myfolder\assets\resources\section1\resource1\item2.jpg"
SetOutPath "$INSTDIR\resources\section4\resource1"
File "c:\myfolder\assets\resources\section4\resource1\item7.jpg"
SetOutPath "$INSTDIR\resources\section4\resource1"
File "c:\myfolder\assets\resources\section4\resource1\item8.jpg"

I have tried a few things but haven't really been able to find a solution. Can anyone point me in the right direction?

UPDATE

Ok, so going on from Aacini's post I have modified the batch file slightly as below...

dir "c:\n\assets" /b /s > "c:\n\original.txt"
type "c:\n\original.txt" | findstr \. > "c:\n\filelist.txt"
@echo off
setlocal EnableDelayedExpansion
SET PATH=C:\n
set INSTDIR="c:\n\assets\"
( for /F "delims=" %%a in (filelist.txt) do (
     set "filePath=%%~DPa"
     set "outPath=!filePath:%INSTDIR%=!"
     if defined outPath set "outPath=\!outPath:~0,-1!"
     echo SetOutPath "$INSTDIR!outPath!"
     echo File "%%a"
  )
) > "c:\n\result.txt"
REM move /Y c:\result.txt files.txt

I made a couple of changes mainly with quotes to allow spaces to be used in the path names, and I also set the path to allow everything to work correctly when being called from NSIS. The problem I am facing now is that instead of....

SetOutPath "$INSTDIR\assets"
File "c:\my folder\assets\startup.xml"

I get....

SetOutPath "$INSTDIR\c:\my folder\assets"
File "c:\my folder\assets\startup.xml"

I imaging it is a real easy fix to resolve but I am pulling my hair out trying to change it! What am I doing wrong?

Answer 1

I have slightly modified your batch:

dir "c:\n\assets" /b /s > "c:\n\original.txt"
FOR /F "tokens=3,4 delims=\" %%G IN (original.txt) DO @echo %%G\%%H| tee -a filelist.txt
@echo off
setlocal EnableDelayedExpansion
SET PATH=C:\n\
set INSTDIR=C:\n\assets\
( for /F "delims=" %%a in (filelist.txt) do (
     set "filePath=%%~DPa"
     set "outPath=!filePath:%INSTDIR%=!"
     if defined outPath set "outPath=\!outPath:~0,-1!"
     echo SetOutPath "$INSTDIR\%%a"
     echo File "!Path!%%a"
  )
) > "c:\n\result.txt"
REM move /Y c:\result.txt files.txt

NSIS can include a directory tree with File /r "c:\\myfolder\\" etc but if you really want to parse a text file you can try something like this:

;create a file list for this example
!delfile "$%temp%\testfilelist.txt"
!appendfile "$%temp%\testfilelist.txt" c:\myfolder\assets\begin.swf$\n
!appendfile "$%temp%\testfilelist.txt" c:\myfolder\assets\resources\assets\text\help.pdf$\n
!appendfile "$%temp%\testfilelist.txt" c:\myfolder\assets\resources\assets\text\license.rtf$\n
!appendfile "$%temp%\testfilelist.txt" c:\myfolder\assets\resources\assets\swf\piano.swf$\n
!appendfile "$%temp%\testfilelist.txt" c:\myfolder\assets\resources\assets\swf\numbers.swf$\n
!appendfile "$%temp%\testfilelist.txt" c:\myfolder\assets\resources\section1\resource1\item1.jpg$\n
!appendfile "$%temp%\testfilelist.txt" c:\myfolder\assets\resources\section1\resource1\item2.jpg$\n

outfile "$%temp%\test.exe"
section
!define srcroot "c:\myfolder\assets" ;batch file needs to generate a relative path for $instdir
!define filelist "$%temp%\testfilelist.txt"
!tempfile BATCH
!tempfile NSH
!appendfile "${BATCH}.cmd" '@echo off&setlocal&goto main$\n'
!appendfile "${BATCH}.cmd" ':StrLen$\n'
!appendfile "${BATCH}.cmd" 'set #=%~2%&set length=0$\n'
!appendfile "${BATCH}.cmd" ':stringLengthLoop$\n'
!appendfile "${BATCH}.cmd" 'if defined # (set #=%#:~1%&set /A length += 1&goto stringLengthLoop)$\n'
!appendfile "${BATCH}.cmd" 'set "%~1=%length%"&GOTO :EOF$\n'
!appendfile "${BATCH}.cmd" ':writ$\n'
!appendfile "${BATCH}.cmd" 'setlocal&set "d=%~2"$\n'
!appendfile "${BATCH}.cmd" 'setlocal enabledelayedexpansion$\n'
!appendfile "${BATCH}.cmd" 'echo SetOutPath "$INSTDIR!d:~%rlen%!" >>"%~3"$\n'
!appendfile "${BATCH}.cmd" 'echo File "%~1" >>"%~3"$\n'
!appendfile "${BATCH}.cmd" 'endlocal&endlocal&GOTO :EOF$\n'
!appendfile "${BATCH}.cmd" ':main$\n'
!appendfile "${BATCH}.cmd" 'call :StrLen rlen "%~2"$\n'
!appendfile "${BATCH}.cmd" 'for /F "usebackq tokens=*" %%A in ("%~1") do call :writ "%%~A" "%%~dpA" "%~3"$\n'
!system '"${BATCH}.cmd" "${filelist}" "${srcroot}" "${NSH}"' = 0
!delfile "${BATCH}.cmd"
!delfile "${BATCH}"
!undef BATCH
!include "${NSH}"
!delfile "${NSH}"
!undef NSH
sectionend

This Batch file do what you need:

@echo off
setlocal EnableDelayedExpansion
set INSTDIR=c:\myfolder\assets\
( for /F "delims=" %%a in (files.txt) do (
     set "filePath=%%~DPa"
     set "outPath=!filePath:%INSTDIR%=!"
     if defined outPath set "outPath=\!outPath:~0,-1!"
     echo SetOutPath "$INSTDIR!outPath!"
     echo File "%%a"
  )
) > result.txt
REM move /Y result.txt files.txt

First test it and check the result.txt file. If everything is OK, remove the REM part in the last command.
