[Pharo-project] [Ann][Cuis] New Cuis Release
by Juan Vuletich Nov. 5, 2010

Nov. 5, 2010

Hi Folks, Cuis 2.8 is available at www.jvuletich.org/Cuis/Index.html . The release notes describes changes in recent versions (starting at 2.0). I believe many of the enhancements could be also useful for Pharo and rather easy to harvest. So, take a look! Cheers, Juan Vuletich

Thanks for the release. I will take look deeper soon. For the moment, I ask: should we integrate Metacello-Base in PharoCore? I guess we can do it in 1.2. cheers Mariano

Yossi did you try Moose? Because moose is a softare analysis platform to build browser and dashboards :) We are working on making sure that Moose built on pharo can analyse pharo itself. This is working but we want to make sure that we can running Moose 4.1 in pharo 1.2 analysing pharo 1.3 unstable.

[Pharo-project] Getting my head around low space
by Max Leske Nov. 4, 2010

Hi I'm having trouble with low space warnings in Pharo. Is there a source on how much memory the image can get from the OS? Is there maybe a way to up that limit? I am loading a lot of data into the image and the limit at the moment seems to be around 500 MB. Thanks for any ideas. Cheers, Max

nick is starting to work on cross compilation toolset and remote debugger in the context of robots but I imagine that his work should let us access remote images. Having an API would be good to be able to query the system and get some information Now orthogonally what we will start to work on and people can help is the following: - we want an object-oriented structural and semantics model of the source code to be versioned in some ways (probably a gemstone db but it could be something else) - we want to have all the code of Squeak and Pharo in that infrastructure so that we can query everything we like. - Other applications should be able to use the same infrastructure for their project.

not right now. you could open an the changes file with from another image or use rst to query objects in an image from another one.

Depending on the context it can also be a selector, e.g. "foo > `key" matches all unary selectors sent to a variable called 'foo'. I wrote that probably in 2000 so this is probably wrong. May be my english was confused too because I took that from john's slides.

So I started to collect the answers so send to the list and for example the questions of doru are a good source I know that I often forgot to handle the other statements in a match. > > Lukas > > -- > Lukas Renggli > www.lukas-renggli.ch >
