SqueakMap question - Can there be 2 MCZ per Package?

Hi,

On SqueakMap, is there a way to create a Package and attach to it 2 or more
MCZ files? (and define the order in which they load) - Or is SqueakMap
strictly 1 Package to 1 related file? This should be another newbie question
i guess...

Thanks Milan

SM is strictly one URL per release (though I did contemplate the
possibility of having multiple but backed out of that, mostly due to
complexity) BUT... you can quite easily put two MCs together into a .sar
file (which is a zip file with some conventions) which has a load script
in it.

I presume there are many examples of this - but I can't point you to
one. But plenty others on this list must have done it before.

Have a look at the FFI installer (quoted below in full). It loads three
MCZs from a particular repository location (for good measure a progress
bar is thrown in for free ;-) Works great, less filling.

"Simple FFI installation script"
repo := MCHttpRepository
        location:'http://source.squeakfoundation.org/FFI'
        user: ''
        password: ''.
'Installing FFI'
        displayProgressAt: Sensor cursorPoint
        from: 1 to: 6 during:[:bar|
        #(
                'FFI-Kernel-ar.7.mcz'
                'FFI-Tests-ar.2.mcz'
                'FFI-Examples-ar.1.mcz'
        ) keysAndValuesDo:[:index :pkgVersion|
                bar value: index*2-1.
                reader := repo versionReaderForFileNamed: pkgVersion.
                bar value: index*2.
                version := reader version.
                version workingCopy repositoryGroup addRepository: repo.
                version load.
        ].
].

Hi!

Ah, yes of course - a static load script. Funny that I forgot about that
option. :)

Note: With "static" I mean that the script loads the same stuff every
time - not the "latest available". That would be a dynamic load script.

PS. It really is time for a complete SM rewrite - there are lots of
lessons learned and things we can do much better. As always.

Interesting. I never even considered that. I guess it's because SM is
versioned itself so it makes more sense to me to map a particular SM
release to a fixed set of package releases.

Andreas, Goran,

Thanks for your help, comments and code. I have a question (and a few notes):

A question for Andreas, when I start squeakMap and look at FFI, under
"download" I see a link to
http://map.squeak.org/accountbyid/cf58c358-46ee-465e-b6db-2740e9b32a53/files/InstallFFI.st 
which is the cool progress bar you pasted below. The
location:'http://source.squeakfoundation.org/FFI' refers to "default
location" where Squeaksouce keeps all files for a project (ending with
projectname, e.g. FFI), is that correct?

Doing it Andreas's way, I will not need to build a SAR - but for curiosity, I
looked for how to build it. Eventually I found Ned's SARBuilder but am not
quite sure how to use it.

As a first time SqueakSource/Map user note, the "Save" on SqueakSource, that
publishes on SqueakMap (does not work as I found out) would be great for
people doing this the first time, but I suspect it tries to just copy one
file from squeakSource to SqueakMap, in a way it would be better if it just
published a small installer code and point to SqueakSource like Andreas's.

I will try to build my SqueakMap project and ask more question if I fail
tonight,

thanks Milan
