NSI and DetailPrint not logging

Question

I am using the NSISLog plugin in my script with the DLL from the site installed in , however the log file is not written to.

Please advise what I am doing wrong?

!define COMPANYNAME "My Company"
!define APPNAME "My App"

InstallDir "$PROGRAMFILES64\${COMPANYNAME}\${APPNAME}"
!define INSTALL_LOG_NAME "install.log"
!define INSTALL_LOG_PATH "$INSTDIR\${INSTALL_LOG_NAME}"
!define PRODUCT_NAME "${COMPANYNAME} ${APPNAME} ${VERSION}"
Name "${PRODUCT_NAME}"
OutFile "installer.exe"

!macro Log str
    MessageBox MB_OK "${str}." /SD IDOK
    ; Log to NSIS console
    DetailPrint "${str}"
    IfFileExists $INSTDIR 0 +2 ; check exists
    nsislog::log ${INSTALL_LOG_PATH} "${str}"
    ; Log to stdout
    System::Call 'kernel32::GetStdHandle(i -11)i.r9'
    System::Call 'kernel32::AttachConsole(i -1)'
    FileWrite $9 "${str}$\r$\n"
!macroend

Function .onInit
    MessageBox MB_OK "Start." /SD IDOK
FunctionEnd
 
Section
    SetOutPath $INSTDIR # define output path
    MessageBox MB_OK "Main." /SD IDOK
    nsislog::log "$INSTDIR\hello-main.txt" "hello"
    !insertmacro Log "$\rhello-main"
    File test.txt
    WriteUninstaller $INSTDIR\uninstaller.exe   # define uninstaller name
SectionEnd
 
Section "Uninstall"
    Delete $INSTDIR\test.txt # Delete installed file
    Delete $INSTDIR\uninstaller.exe # Delete the uninstaller
    RMDir $INSTDIR # Delete the directory
SectionEnd

I am running v3.08 and the flags are below:

Answer 1

That plug-in is not Unicode compatible. You could add Unicode False to the top of your .nsi script but ideally you should build a Unicode installer.

You can just replace the plug-in with a simple function:

!define FileAppendLine '!insertmacro FileAppendLine '
!macro FileAppendLine f l
Push "${l}"
Push "${f}"
Call FileAppendLine
!macroend
Function FileAppendLine
Exch $0
Exch
Exch $1
FileOpen $0 $0 a
StrCmp $0 "" err
FileSeek $0 0 END
!if "${NSIS_CHAR_SIZE}" > 1 ; Replace this with "!if 0" if you always want to force ASCII (not all strings might convert correctly)
FileWriteUTF16LE /BOM $0 $1
FileWriteUTF16LE $0 "$\r$\n"
!else
FileWrite $0 $1
FileWrite $0 "$\r$\n"
!endif
FileClose $0
err:
Pop $1
Pop $0
FunctionEnd


Section 
SetOutPath $InstDir
${FileAppendLine} "$InstDir\install.log" "Hello"
${FileAppendLine} "$InstDir\install.log" "World"
SectionEnd
