Code Formatting
by Mike Hales 28 Jan '10

28 Jan '10

I'm cross posting this because my question is both about Squeak Trunk and Pharo. Feel free to respond only in your respective lists if you want. I'm running on Snow Leopard. I'm getting a package ready that I want to publish, and I wanted to test it on both on Pharo and Squeak Trunk, and both are bothering me a little. Squeak - I'm using the latest pre-built trunk image, updated with the update button. The command-r (pretty print) shortcut only seems to work if the selectors list has the mouse focus, not the code pane. Then after pretty printing, to save the source, I have to move the mouse focus back to the code pane, where command-s will save the change. If I have to move the mouse around what good is the shortcut? Pharo - I using the latest Pharo 1.0 release candidate (dev not core) It seems like the coloring, and automatic completion work right out of the box, but when I choose "format" from the code pane context menu, nothing happens. Do I need to load something else? Also, if it were to work, what would I have to do to get a keyboard shortcut for it. Since so many of you write so much more code than me, I imagine that there are simple solutions. And while we're here, I wouldn't mind some suggestions regarding how to "pimp my image" so to speak, to make the development flow better. Thanks, Mike Mike Hales Engineering Manager KnowledgeScape www.kscape.com

[Cuis] Applying updates
by keith 27 Jan '10

27 Jan '10

Juan, I am a little curious as to how you apply your updates. The code in method Utilities>>#applyUpdatesFromDiskToUpdateNumber: lastUpdateNumber stopIfGap: stopIfGapFlag contains the line ... ifFalse: [fileNames _ updateDirectory fileNamesMatching: currentUpdateNumber printString , '*'. ... which in my book would not match any of your updates numbered with $0 padding. Am I missing somehting obvious? Keith

Texture rendering into shared memory?
by Lawson English 27 Jan '10

27 Jan '10

Anyone ever use the OpenGL shared memory texture rendering with squeak? I have potential uses for it, but its hard to map the squeak way unto the C source examples, expecially when squeak seems to be doing so much behind the scenes already. Lawson

Cross fork compatibility of packages: A proposal
by Juan Vuletich 27 Jan '10

27 Jan '10

Hi Folks, Package developers want their work to run on various Squeak versions and variants, without needing rewrite. Same for app developers. Base image builders want to be free of the need to provide backwards compatibility. This is what I suggest: A package assumes it can use a set of apis of the Squeak (/Pharo/Cuis/Etoys/Tweak/Cobalt/etc) environment. Those assumptions should be made explicit, in the form of tests. So, for example, for collections, some package developer might require the "Common Collection API tests" to pass. Then, if his package fails to run, let's say in Cuis, he would run the tests for the apis he needs. If some test fails, he could say "Cuis developers, you're not supporting api XXX", end expect them to fix the issue. But if no test fails, he needs to either modify his code so it doesn't use not-standarized apis, or he could negotiate with (all) base image developers the addition of a new api or use case to the test suite and the base images. Building these suites is quite some work, mostly to be done by package developers. But it can easily point out responsibilities and duties. It frees package developers of needing to have a deep knowledge of various base images. And it frees base image developers from needing to know details about an unbounded set of external packages. Besides, it puts popular packages that everybody wants to support on equal footing with less-known packages. It also lets base image developers say "we support Common APIs xxx, yyy, zzz, etc.". All what I say about base images could also apply to packages that offer services to other packages: There could also be test suites to specify their services, and allow users to switch versions of the packages they use knowing what to expect. What do you think? Cheers, Juan Vuletich
