Installer to distribute greasemonkey scripts

Posted on 2009-07-14
Last Modified: 2013-12-12
I have a few greasemoneky scripts that need to be distributed to other computers that may or may not have firefox installed.  The installer has to be understandable by users with low technical experience.  It will also have to be able to edit the files to include install/location specific data.  I have basic knowledge of NSIS and think that it can be used for this project, but I don't know how to write it.

If someone could at least provide instructions on how to determine if firefox is installed, if greasemoneky is installed, where to put the scripts, and a way to download the latest versions of firefox and greasemoneky.

Ideally the installer could make the same scripts also work with IE and Opera if installed and/or preferred (the scripts don't have any greasemonkey-specific calls).

Have a look at the following:

I know where the scripts are and have already manually copied them to another computer, but it is a rather technical process that must be automated for non-technical users.

Are you in a position where you can buy an install package such as Installshield?  All of this would be very easy with installshield, though that's going to cost some money up front obviously.  I can give detailed info on this, if it is an option.

Otherwise, Nullsoft is indeed what I would recommend.  Here's some information about installing prerequisites with NSIS...which is essentially what you want to do (make sure Firefox/GM are installed).

Installshield is a bit expensive for this project.

I think I know how to check if firefox is installed, but I'm not sure about checking for greasemonkey (not that it matters, I think, because firefox would just reinstall it).  I would like for the installer to download the latest versions of firefox and greasemonkey rather than having a single version packaged with it that would have to be updated with each new version of firefox.  I will need, though, to determine the location of the current firefox profile in order to copy the scripts.

I will make a simple diagram to describe what I want the installer to do.

Well...this is just theory here but this is how I would check for GM (once I know Firefox is there).

Navigate to this directory:
C:\Documents and Settings\<windows username>\Application Data\Mozilla\Firefox

Inside this directory there is a profiles.ini file that will tell you the current profile name.  Here's what mine looks like...



So, now you have a profile name (and therefore the profile subfolder) where you would want to copy the GM files to.  A quick Google search should lead you to more info about the profile directory structure of Firefox.  I don't know enough about GM to know if it needs registry settings or not.  There appears to be a subfolder inside the profile folder where the extension files all reside.  But you can easily create registry entries if you have the windows rights when the install is run.

Once you know all of this info, you should be able to get Firefox and GM installed.  It will take some work, and I don't see any examples of exactly this anywhere, but it certainly seems possible.

Good luck, and hopefully this answer at least helps!

That makes sense.  What I need to know is how to read the ini file with nsis to find the path, then how to save that to navigate to it.

The other part I need is the downloader.  I am fairly sure that nsis can do it, but I don't know how to.  The static greasemonkey xpi url (doesn't change between versions) is simple to find; I don't know of a static one for firefox though.

I hope to start working on some code tomorrow so will post more specifics and some code then.

I have begun coding and have completed installing firefox.

I think I can code most of it, but what I will really need help with is reading the ini file to get the profile directory.

I have also decided to just embed the firefox installer in my own and then let firefox update itself once installed (but haven't implemented that yet).

My code so far is attached.

!include "MUI2.nsh"

!include "LogicLib.nsh"

!include TextFunc.nsh

!include StrFunc.nsh

Name "InstallGreasemonkeyScripts"

OutFile "install.exe"

ShowInstDetails show

RequestExecutionLevel admin

InstallDir "$EXEDIR\test"

!insertmacro MUI_PAGE_WELCOME


    !insertmacro MUI_LANGUAGE "English"

Section main

	SetOutPath "$INSTDIR"

	ReadRegStr $R8 HKLM "SOFTWARE\Mozilla\Mozilla Firefox" "CurrentVersion"

	ReadRegStr $R9 HKLM "SOFTWARE\Mozilla\Mozilla Firefox\$R8\Main" "PathToExe"

	${If} $R9 == ""

		DetailPrint "FF not installed"

		DetailPrint "Downloading Firefox"

		${Unless} ${FileExists} "firefoxSetup.exe"

			inetc::get /RESUME "" /POPUP "" " Setup 3.5.exe" "$INSTDIR\firefoxSetup.exe" /END

;		  Pop $0


		${If} ${Cmd} `MessageBox MB_YESNO "Install Firefox with default settings?" IDYES`

			ExecWait "firefoxSetup.exe -ms"


			ExecWait firefoxSetup.exe





		DetailPrint "FF is installed"

You'll want to use the ReadINIStr and/or WriteINIStr methods I think to interact with the .ini file.  The .ini file will always reside in the %APPDATA%\Mozilla\Firefox directory on the machine.  here are a couple of links I found that should be useful examples.

Seems like once you have that you should pretty easily track down where to place the GM scripts etc.

I will also need to edit the scripts from within nsis with data imputed by the user.

I assume GM scripts are text files then?  There are a ton of text manipulation functions in NSIS.

And here is the recommended plugin for user input:

Sorry for the delay, I changed the design some, but your information helped.  I have completed the installer.
