How to save DetailPrint command message in a file in NSIS Script?

Question

The idea is to run the NSIS script in silent mode on a remote computer and after a successful installation, than return the log file to the host machine.

I have many Detailprint command messages that show the progress of the script. Now the question is how to save these messages in a log file. I studied this http://nsis.sourceforge.net/Dump_log_to_file , but it says that it will not work in silent mode.

Answer 1

I use this method to save logs. I don't know if this is the best method, but it works well for me.

 !ifndef DEBUG_MODE !define DEBUG_MODE true !endif !define LOGFILE "$TEMP\my_logfile.log" !if ${DEBUG_MODE} == true !define DetailPrint '!insertmacro _debugMsg' !else !define DetailPrint '!insertmacro _nodebugMsg' !endif !macro _debugMsg MSG push $3 push $2 push $1 push $0 push $R0 strcpy $R0 "${MSG}" ClearErrors FileOpen $1 ${LOGFILE} a FileSeek $1 0 END IfErrors +8 ${GetTime} "" "L" $0 $0 $0 $0 $0 $2 $3 FileWrite $1 "$0:$2:$3$\t" FileWrite $1 "${__FUNCTION__}$\t" FileWrite $1 "$R0" FileWrite $1 "$\t(${__FILE__},${__FUNCTION__},${__LINE__})" FileWrite $1 "$\n" FileClose $1 pop $R0 pop $0 pop $1 pop $2 pop $3 !macroend !macro _nodebugMsg _MSG ;you can put here nothing or you can put the regular DetailPrint DetailPrint "${MSG}" !macroend 

After that, you just need to find and replace DetailPrint with $ {DetailPrint}

This is true, the list box is not in silent mode.

I think you have two options: copy your own log:

 var hFileLog !macro Log_Init logfile FileOpen $hFileLog "${logfile}" w ;Or "a" for append !macroend !macro Log_String msg DetailPrint "${msg}" FileWrite $hFileLog "${msg}$\r$\n" !macroend !macro Log_Close FileWrite $hFileLog 'Done.' FileClose $hFileLog !macroend !macro File src File "${src}" FileWrite $hFileLog 'Extracting "${src}" to $outdir$\r$\n' !macroend Section "Main Program" !insertmacro Log_Init "$instdir\install.log" !insertmacro Log_String "Starting install..." SetOutPath $instdir !insertmacro File "${__FILE__}" SectionEnd Section "Optional Foo Component" !insertmacro Log_String "Installing Foo" SectionEnd Section !insertmacro Log_Close SectionEnd 

or add more hacks to make DumpLog work:

 Function .onInit IfSilent 0 +2 StrCpy $0 1 ;We need to know if we are in "real silent" mode SetSilent normal ;Turn off real silent mode so we can fake it FunctionEnd Function .onGuiInit StrCmp $0 1 0 +3 HideWindow SetSilent silent ;The docs say this is only supported in .onInit but all we care about is the internal flag used by IfSilent FunctionEnd LicenseData "${__FILE__}" page license skipifsilent ; All pages except instfiles needs this hack page directory skipifsilent page instfiles Function skipifsilent IfSilent 0 +3 HideWindow Abort FunctionEnd Section IfSilent 0 +2 HideWindow SetOutPath $instdir File "${__FILE__}" Sleep 2222 ;So we can see that it is hidden and not just finishing quickly DetailPrint "$(^Completed)" ; Fake the completed message show it shows in the log Push "$EXEDIR\install.log" Call DumpLog IfSilent 0 +2 Quit SetDetailsPrint textonly SectionEnd !define LVM_GETITEMCOUNT 0x1004 !define LVM_GETITEMTEXT 0x102D Function DumpLog Exch $5 Push $0 Push $1 Push $2 Push $3 Push $4 Push $6 FindWindow $0 "#32770" "" $HWNDPARENT GetDlgItem $0 $0 1016 StrCmp $0 0 exit FileOpen $5 $5 "w" StrCmp $5 "" exit SendMessage $0 ${LVM_GETITEMCOUNT} 0 0 $6 System::Alloc ${NSIS_MAX_STRLEN} Pop $3 StrCpy $2 0 System::Call "*(i, i, i, i, i, i, i, i, i) i \ (0, 0, 0, 0, 0, r3, ${NSIS_MAX_STRLEN}) .r1" loop: StrCmp $2 $6 done System::Call "User32::SendMessageA(i, i, i, i) i \ ($0, ${LVM_GETITEMTEXT}, $2, r1)" System::Call "*$3(&t${NSIS_MAX_STRLEN} .r4)" FileWrite $5 "$4$\r$\n" IntOp $2 $2 + 1 Goto loop done: FileClose $5 System::Free $1 System::Free $3 exit: Pop $6 Pop $4 Pop $3 Pop $2 Pop $1 Pop $0 Exch $5 FunctionEnd
