Re: [Pharo-project] [ANN] Traits installer/uninstaller utility

Hi Bill, thanks for the good wishes :-) Regarding rendering times, I dont have any problems, usual interactions are snappy. Have a look at the screencasts to see the tool in action, especially the second one ( http://pleiad.dcc.uchile.cl/research/software/aspectmaps_struct_zoom ) to see what I mean. AspectMaps is built using Moose ( http://www.moosetechnology.org ) and more specifically using an extended FAMIX model of Java as the data structure and the Mondrian ( http://www.moosetechnology.org/tools/mondrian ) visualization engine to do the visualization. I could not have done it without these tools and the guys behind the tools helping me out where I needed :-) So if you want to do some kind of visualization of data I highly recommend you to check this out!

Taking a really quick look at your web site, this looks like something that could take a lot of time rendering graphics. Is drawing time a problem for you? Did you do anything in particular to avoid bottlenecks? I ask because I am starting to port some of my graphical code to Pharo; some of it is going from home-grown to using gnuplot, but elsewhere I was able to simply pass (Windows speak) an HDC into a function in a DLL and do a lot of rendering fairly quickly as a result. I am still looking for how to approach that in Pharo+Linux. I am starting to make my own .so's with success, but have yet to produce graphics that way. > > Bill > -- Johan Fabry jfabry(a)dcc.uchile.cl - http://dcc.uchile.cl/~jfabry PLEIAD Lab - Computer Science Department (DCC) - University of Chile

The VM has the relevant functionality. It is easy to construct a special save-as that resizes the screen (or puts it into full screen mode), saves, and then restores the display to what it was. The above is useful when one wants to change an image file after the fact. And again it is easy to construct a special save-as that saves and then rewrites the image header, which would allow one e.g. to save a large display image file on a small display machine. The KISS principle agues against modifying the VM to take a series of variables that overrode the actual display size on save. If the iage header is well-defined (it hasn't changed in a loooong time) ten the above is fine, no? BTW, since Cog is using a number of other bits in the full-screen flag word for other values (platform-dependent float order, whether process preemption yields, etc) the above should read something like seDisplayExtent: extent fullScreen: fullScreenFlag iInImageFile: imageFileName | fs flags | fs := StandardFileStream fileNamed: imageFileName. fs binary. [fs position: 28. flags := fs nextLittleEndianNumber: 4. flags := fullScreenFlag ifTrue: [flags bitOr: 1] ifFalse: [flags bitClear: 1]. fs position: 24. SmalltalkImage current isLittleEndian ifTrue: [fs nextLittleEndianNumber: 4 put: (extent x bitShift: 16) + extent y.

I'm correct? > Yes...imagine today you copy your Conf to Pharo10MetacelloConfiguration ... today the working version for Pharo 1.0 is 1.4.5. Then...you continue to develop. Of course, using the same conf. Then you have version 1.5, 1.6, 1.6.2 , etc Suppose that now we have Pharo1.1 and you do the same: you copy your new version of the conf to Pharo11MetacelloConfiguration. How do people know WHICH version of the conf work for EACH pharo version ? That's why I had the idea that every developer implement load to instead of loading the last version, to load the last version that WORKS for that Pharo version. So probably, the conf you copy to Pharo10MetacelloRepository may be load self version: '1.0.xx' load and in Parho11MetacelloRepository it would be load seld version: '1.6.xxx' this is just an example. Having this, it also gives us an API: Everybody will know how to install it: just evaluate load.

It works, but ONLY appling it to another image....which in such case I rather shell :( I tried: | fs | fs := StandardFileStream fileNamed: (SmalltalkImage current imageName). fs binary. [fs position: 24. SmalltalkImage current isLittleEndian ifTrue: [fs nextLittleEndianNumber: 4 put: (1024 bitShift: 16) + 768. "Display size" fs nextLittleEndianNumber: 4 put: 0.
