Hi, since MSDN states that any installer that requires JScript/VBScript must make sure to install it, and since some applications require these for install (bug #7353 and another one is there for VBScript for a different installer), I figure there is no reason why builtin MSI cannot use Microsoft Script if it is there (and plus when we have our own JScript/VBScript we will be able to use it off the bat with MSI).
I have posted my initial work on this on the bugzilla for bug #7353. The first file (a patch, will attach also) is my patch which updates custom.c to have the appropriate handlers for the custom action types, extracts the script from the appropriate place, writes it to a file, and uses a framework very similar to the current thread framework for DLLs to call my helper call_script function. This first patch, in theory, should not have to change much (if at all), although I have not thoroughly tested it yet so it probably will.
The second file (and attached here too) is dlls/msi/script.c, which is where the meat and potatoes of the actual call_script function is/will be. Right now it is pretty barebones, but it does load the script from the file and calls it appropriately.
Now I am working on implementing the Session object, although it looks like a wrapper around MSI functions we already have so I think it should be doable.
Anyways, any comments on my work so far will be appreciated.
