Hi Mariano,
One thing I don't understand of Metacello is why don't you use #latestVersion (or #latestReleaseVersion, #latestDevelopementVersion, etc) instead of specifying the version number (e.g. '1.3'). How do you keep updated about the latest version numbers?
This is an excellent question :)
In summary, there is a current problem with Metacello and Pharo: a user
of a
project doesn't know which is the stable version for a pharo specifc version. For example, in this case suppose FFI 1.1 is the stable for Pharo 1.0 and FFI 1.3 for Pharo 1.1. How can the user know that? there is no easy solution. This is why Dale, me, stef, marcus, esteban, etc, have been discussed last week in ESUG. I will then send a summary about the possible solution.
Do I need to know the version numbers?
Depends on your needs. If you want to be able to recreate/reproduce it, then yes (at least right now).
As an user I don't want to know the version number until extremely necessary, i.e. I'm not switching everyday from 1.0 to 1.1 to 1.2 then back to 1.1, etc. Eventually I try newer versions of Pharo to see what I'm missing, and I choose to update acoordingly to the stability of the whole set of packages concerning my application. It's not like I evaluate the same "install base packages" script I've evaluated 6 months ago :)
Ok, that's your use-case. OThers need exactly that :)
By the way if you want to support internally the package status you may try the Specifications pattern?
Anyway, if I use latestVersion, I am not sure you will load that again.
I'm sure I will never load it again. Got it? :)
yes. That's a use-case. Fortunatly Metacello is flexible enough to support both. Anyway, did you read my email about stable versions? I think that will clarify everything....since we will be able to use #stableVersion. Cheers Mariano
Ok....I assumed he was using Pharo 1.1 (because is the current latest stable release). Then, I KNOW that FFI 1.3 works well with Pharo 1.1. If he takes the same image, and in 6 months someone releases FFI 1.4 that doesn't work anymore with Pharo 1.1, then it will fail.
Cheers

Hi Bruce. The recommended way to install external packages in Pharo is now using Metacello.
To install FFI in Pharo, evaluate:
Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfFFI'; load.
((Smalltalk at: #ConfigurationOfFFI) project version: '1.3') load.
For more information about Metacello:
http://code.google.com/p/metacello/
or you can see the talk we give with Dale last week at ESUG.
Cheers
Mariano

I noticed in Pharo 1.1 that the loadFFI script in the script loader
is
no longer there. How can I load FFI into Pharo 1.1. I noticed that the shared library is there but that there are no supporting FFI Classes. Thanks for the Help.
