[squeak-dev] Alien in trunk, for real

Hi,

did it. :-)

Here's the recipe that works for me to get Alien up and running (Mac,
4.2.1 VM, recent trunk image):

1. install my Compiler patch from Inbox
2. install Alien-Core-First (most recent from SqueakSource - this
holds for all Alien packages below)
3. install Alien-Core
4. install Alien-Examples
5. install Alien-LibC
6. install Alien-CoreTest
7. install Alien-Last-Class-Initialize
8. do
Smalltalk allClasses
        select: [ :class | class category beginsWith: 'Alien-' ]
        thenDo: [ :class |
                class methodDictionary do: [ :method |
                        class recompile: method selector ].
                class class methodDictionary do: [ :method |
                        class class recompile: method selector ] ]

Next, fire up TestRunner, select the Alien tests, run them, watch the
bar go green. :-)

I'd like someone to help me in packaging this as a complete update
that can be installed from the trunk repositories, including the last
recompilation step.

Best,

Michael

because, for some reason I don't know, the Alien methods containing
primitives all had primitive number 0 and would therefore yield
nothing but primitive failures.

Much better. :-)

What do I have to do to make this a proper package? Something about
Monticello prologues and epilogues? (No experience there on my
behalf.)

Best,

Michael

Good that you made that! :)

2009/9/2 Michael Haupt <[hidden email]>: Hmm.. Is it possible that a patch to the compiler were in a kind of
'hibernated' state before you loaded the Alinen.
Or is it possible that you are patched the compiler when you had alien
already loaded - that's why you could
end up with primitive index being = 0.
I'm just trying to guess what is happened.

good point ... let me try ... no. The recompilation step is required.

BTW Bert's code gives me a debugger. This seems to be because there is
a problem in the category Alien-Core - one of the classes is displayed
as "NotFoundError", and this is a very unhealthy thing (clicking on it
yields a debugger).

So something screwed up the Alien-Core category. More to look at.

Best,

Michael

Hi,

after having submitted a patch to Alien (thanks, John, for letting me
write to the repository), I now have uploaded a package called
AlienInstaller to the *Inbox*. Once that's installed, you can use
"AlienInstaller install" to install all the Alien packages and
recompile the required classes after that.

It uses Installer internally.

Thanks to Igor for helping me! :-)

Best,

Michael

Yeah, Bert, that's what i said to Michael when he about to post this
message. There have to be the simpler way. :)

... and yet we were wondering what it might be.

Some thinking later ... a Monticello configuration? (Is it possible to
attach epilogues to those?)

Always willing to learn,

The simpler way is called InstallerScripts in Installer-Scripts

Keith

I'm wondering if we aren't talking besides each other here. If you've
used Installer internally already, why can't you just a script that does
the same as you have in your class?

(Installer squeaksource project: 'Alien')
        install: 'Alien-Core-First';
        install: 'Alien-Core';
        install: 'Alien-Examples';
        install: 'Alien-LibC';
        install: 'Alien-CoreTest';
        install: 'Alien-Last-Class-Initialize'.

Or am I missing a point here?

Cheers,
   - Andreas

maybe *I* am. I'd like to have the Alien installation *packaged*
somehow; i.e., copy-and-pasting the Installer script to install Alien
is not what I prefer. The AlienInstall thing was the easiest thing
Igor and I could spontaneously come up with to make this *packaged*.

Best,

Michael

2009/9/3 Michael Haupt <[hidden email]>: Right, i also proposed the alternative - put installer script on a
wiki somewhere
and use 1-liner installer script to install from squeak.
But i think, MC is still better, since you don't need to remember even
script url or something,
because everything (Alien + its installing script) could be put into
single MC repo and whenever someone needs
to install it, he just doing it right.

Hi,

the AlienInstaller-mha.4.mcz package automatically starts Alien
installation after the AlienInstaller package has been loaded. It's
about as "packaged" as I could make it with my limited capabilities.
;-)

Best,

Michael
