[ANN] LatAm Squeaksource Mirror

by Johan Fabry

Hi all, I'm happy to announce that we have a public, read-only Squeaksource mirror up and running at the Universidad de Chile. The URL is: http://www.dsal.cl/squeaksource/ TECHNICAL DETAILS BELOW. Feel free to broadcast this announcement! MOTIVATION: For us, Switzerland is a long way and the connection to Squeaksource has always been painfully slow. We've set up this mirror to help to address this, and I imagine that it will be of use not only for the Chileans but also other countries in latin america, which is why I am announcing it here. ITS TRANSPARENT: I've worked out a way to make the use of this mirror transparent when using Pharo 1.3: you just use monticello as always, and have a setting to redirect loads from Squeaksource to wherever you want. I have successfully loaded Moose and Seaside from the mirror using this package, so it should work for you. And I can tell you, it was blazingly fast: Seaside loaded in 5m45, and most of the time was spent compiling ... ;-) So try the mirror and the package out, send me your comments, we want to work on this to make Squeaksource a better experience for everybody. HOW TO USE from Pharo 1.3: - Get the redirection package from http://www.squeaksource.com/MonticelloRedirect - To load from the mirror instead of from Squeaksource, do-it of the following: MRManager redirectFrom: 'http://www.squeaksource.com/' to: 'http://www.dsal.cl/squeaksource/'. - To remove this redirection: MRManager removeFrom: 'http://www.squeaksource.com/'. - See comments of MRManager for more info. MRManager list can be useful at some times. - Only 2 classes, < 10 methods, not counting accessors. The trick is the use of MethodWrappers. - I did not test this in Squeak or other versions of Pharo. Feel free to try it out in your environment and send me patches if needed. - There is no UI, contributions are welcome!! DETAILS ON THE MIRROR - It's a full copy of Squeaksource, updated daily. - The mirror is read-only: if you want to make a commit you still have to do it in Squeaksource.

MethodSpy>>isAbstract DNU errors.

by Paul DeBruicker

Hi - I'm using Hapao (downloaded today) and Pharo 1.3 and noticed that there are a bunch of DNU errors reported in the transcript. The missing method is either from the MethodSpy class or the HapaoTestCoverageMethodSpy class. Adding MethodSpy>>isAbstract ^false "fixes" the errors that are reported to the Transcript. But I'm not sure what the isAbstract test is all about so don't know what functionality I'm missing. Thanks Paul

Re: [Pharo-users] Using Pier as a CMS for a personal site (layouts and urls question)

A good starting point is to familiarize yourself with Blueprint, which is the basic layout framework used in Pier: http://www.blueprintcss.org/ > * I see the blog on Ramon Leon ( onsmalltalk.com ) without the ugly urls and the Doru's site have clean urls. The method to get them in Seaside is documented in the Ramon's blog. Is the same for Pier (being Seaside based) or there is any other procedure? The reason is that I am using an old version of Pier/Seaside that got the URLs fixed. The latest one lost the solution.

Yes that was meant to be constructive, sorry if it sounded otherwise! :( I agree with you about the instance variables, if you're going to do it in Pharo you won't need the random variable either, check out the code I attached in a previous mail.
