Dear Pharoers We are pursuing an effort to bring Pharo to the next level: we will set up a consortium of pharo users and industrial partners. Our goal is to build a legal infrastructure that will be able to sustain the development of Pharo and improve its future. As an example, we would like to be able to collect funds (ways as to be determined - we foresee a membership model or moral license) to pay engineering tasks to be performed such as improving the virtual machine, network libraries, better JIT support. To make it short we would like to give a chance to our community to grow and structure itself so that Pharo can get stronger and that risk (truck factor) gets minimized. We are contacting you to know if your company/research group would be interested to support such effort. Showing such interest is strategically important for us and INRIA which could also support such effort. Attached is the letter of support that we will collect once signed and scanned ( stephane.ducasse(a)inria.fr / faxed at: 00 33 (0)3 59 57 78 50) Thanks for your support The Pharo Board M. Denker, S.

Lint checks & automated clean-up of unnecessary code.

by Paul DeBruicker

Hi - Is there some place I could read about how automate the fixing of various lint checks? In a package I've written I have some sloppy parts left over from trying things, then trying other things, then finally settling on another approach entirely. For instance I have 84 instances of "Temporary variables read AND written" (RBOnlyReadOrWrittenTemporaryRule). I have 300+ methods that are implemented but not sent (RBImplementedNotSentRule), 10 un-referenced classes (RBClassNotReferencedRule), etc..... I could definitely go through and delete the temp variables by hand but am hopeful that I could just nuke them all at once, then run my tests and see what, if anything, needs replacing/repairing. Thanks for any guidance you can provide. Paul

Dependencies and Monticello

by Andrew Black

I probably don't understand how to use Monticello dependencies correctly. Here is the situation. Your help appreciated. I'm writing code that uses PetitParser. So, I added to my own package a dependency on PetitParser. Strangely, rather than linking to the PetitParser repository, this copies PetitParser into my repository when save a new version on my package. The problem is that I have found it necessary to change a few definitions in *PetitParser. (I would call these bug fixes, but that is a matter of opinion.) I didn't think that would be a problem; I put the overriding definitions into my package, and everything worked fine. That is, it worked fine until I started with a clean image and loaded my package. Monticello apparently loaded my package, and then loaded PetitParser. This over-wrote my (bug-fix) definitions with the original ones. Most of my tests failed. If I load my package a second time, them my definitions overwrite the ones from PetitParser, and all is well. I infer that Monticello packages are supposed to be load-order-independent. So, what is the right way to fix this problem (other than convincing Lukas that trimSpaces should, indeed, trimSpaces)? Andrew

Re: [Pharo-users] About Coral

by Adrien BARREAU

Hi, Since many things are not finished yet in Coral, I don't think there is any documentation. The only thing I know is a French tuto made by Olivier. And it can't run under Windows. However, I can answer your questions. Do you want that script to be run in a command line or in Pharo? Because you can do that kind of things in Pharo without Coral, only with FileSystem. If you want to try Coral, you may install it: 1. Load the last ConfigurationOfCoral (http://www.squeaksource.com/Coral) 2. Install last version 3. CoralInstaller generateCoralScript. 4. CoralInstaller generateAllExamples. Coral.sh will be created in your image folder; it of course need a chmod +x. Open a command line and go to that folder. Then you can run your scripts by: ./coral.sh theScript.cst. Take a look to the examples for the syntax, there is only a couple of thing added to Smalltalk syntax.
