File command, is this possible?

I've posted this before but I can't find it.

I have a directory structure as follows:
MAIN_DIR
---Client1
---Client2
---Client3

I !define which client the installer is being compiled for.

If there is a file called test.txt in MAIN_DIR and a file called test.txt in the Client1 directory, I want to include the one from Client1 only.

If there is a file called test.txt in MAIN_DIR and not in the Client1 directory, I want to include the one from MAIN_DIR.

In other words, if there is a file in the defined Client directory, it should override the one in the MAIN_DIR.

Is this possible?

Thanks.

IfFileExists, Delete and Rename commands are going to work for you in this case EXCEPT if you want to include it inside the installer as a File command.

I've done something very much like this before.
!macro ClientFile FILE_NAME

  !system 'if exist ${CLIENT_DIR}\${FILE_NAME} \

              echo File ${CLIENT_DIR}\${FILE_NAME} >$%TMP%\temp.nsh \

           else \

              echo File ${MAIN_DIR}\${FILE_NAME} >$%TMP%\temp.nsh'

  !include $%TMP%\temp.nsh

!macroend





!insertmacro ClientFile test.txt
I've not tested the above, but it was something along those lines.

Thanks eccles.

This is what I ended up with.

All of the files in question end up in one temporary file which is then !includ(ed)

${kCLIENT} is a !define that is set up in the BAT file that calls the installer.

!define CLIENT_TEMP_FILE "$%TMP%\temp.nsh"

!macro InitClientFile

   !system 'del /q "${CLIENT_TEMP_FILE}"'

!macroend



# Put a SetOutPath line before a list of files.

!macro AddPathClientFile THE_PATH

   !system 'echo. >>"${CLIENT_TEMP_FILE}"'

   !system 'echo SetOutPath "${THE_PATH}" >>"${CLIENT_TEMP_FILE}"'

!macroend



# Accept the top-level directory and filename and decide whether to take the file

# from the CLIENT sub-directory or the main top-level directory.

!macro ClientFile FILE_DIRECTORY FILE_NAME

   !system 'if exist "${FILE_DIRECTORY}\${kCLIENT}\${FILE_NAME}" \

      (echo File "${FILE_DIRECTORY}\${kCLIENT}\${FILE_NAME}" >>"${CLIENT_TEMP_FILE}") \

      else \

      echo File "${FILE_DIRECTORY}\${FILE_NAME}" >>"${CLIENT_TEMP_FILE}"'

!macroend



# Add these file to the installer script.

!macro IncludeClientFile

   !include "${CLIENT_TEMP_FILE}"

!macroend

To use it in the installer:



   !insertmacro InitClientFile



      !insertmacro AddPathClientFile "$ApplicationDir\myDir"

         !insertmacro ClientFile "..\myDir" "aaa.txt"

         !insertmacro ClientFile "..\myDir" "bbb.txt"

         !insertmacro ClientFile "..\myDir" "ccc.txt"



      !insertmacro AddPathClientFile "$ApplicationDir\myDir2"

         !insertmacro ClientFile "..\myDir2" "xxx.txt"

         !insertmacro ClientFile "..\myDir2" "yyy.txt"

         !insertmacro ClientFile "..\myDir2" "zzz.txt"



   !insertmacro IncludeClientFile
