Stories for Pharo News Blog and Success Stories

by Marcus Denker

Hi, We should try to post something every week to the Pharo news blog. One interesting kind of content are projects done with Pharo. So if you have something to share: we would be interested in -> short text that describes the project -> URL to website -> a cool screenshot Especially interesting are of course for one commercial projects (Things like http://www.t3-platform.net) The other class I like are Research Projects. They are always fun and force us to think and dream. http://www.languageoflanguages.org is a nice example. Third: Infrastructure. Like the new http://jquerymobile.seasidehosting.st So if you have ideas --> send a mail. Best would be finished small articles to ready to post. -- Marcus Denker -- http://marcusdenker.de

How to get temp names of BlockClosure

by Norbert Hartl

I'm trying to learn how to get temp names from a BlockClosure. Well, I try to be able to treat BlockClosures the same way than CompileMethod when it comes to arguments. I can do [:a :b :c| ] asContext tempNames #('a' 'b' 'c') but I'm not sure if this is the best to go. While looking I found [:a :b :c| ] method tempNames #('[a' 'b' 'c]') For me there are two errors. The obvious one is that the first element is [a instead of a (it splits the string "[a b c]" by spaces). The second point is that "method" is defined as "outerContext method" and I don't understand why it is visible as temps there. It gets the information from the method trailer. Is this a reminiscent from the pre-closure times? thanks, Norbert

Hi Lukas Thanks for taking a look. And sorry about the private repository; there are still a couple of things we are wrapping up right now for the demo. The repository will be made public soon. We'll also post an image (+documentation) with all the examples built-in after the demo (per Stef's suggestion). I'll update the mailing list when that happens. -- Nick Lukas Renggli wrote: > > Hi Nick, > > Looks interesting.

Stef Good idea. We will post an image after the demo with the examples. Thanks for the suggestions on Helvetia and PetitParser. We'll take a closer look at Helvetia since the goals overlap. I am aware of PetitParser and am planning to see how we can integrate it in. Right now we are using Jamie's CAT parser (continuation of the work he did with Allesandro Warth and Todd Millstein [1]).

Thanks Nick for letting us know. Good luck. I suggest that you propose a ready to use image on your web site. BTW did you see Helvetia and PetitParser? Because they can help you.

Hi Nick, Looks interesting. I followed your download instructions, but unfortunately the Monticello project on SqueakSource is marked as private, so it cannot be installed.

[ANN] Language of Languages Demo at SPLASH '11

by Nick Chen

Dear Smalltalkers Jamie Douglass, Ralph Johnson and I are working on an experimental language workbench called Language of Languages (LoLs) that focuses on unifying concepts (meta-models) across different notations. This affords the user greater flexibility for editing the model in a variety of different notations while maintaining consistency. We are building this language workbench on top of Pharo Smalltalk[1] and we are using the Glamour engine[2] to build some of the language browsers. If anyone is attending SPLASH[3] this year, we'd like to invite you to one of our demo sessions. You can find a schedule of our demos at http://languageoflanguages.org/news. You can find more information about LoLs from our website at http://www.languageoflanguages.org. Hope to see you at SPLASH '11! -- Nick University of Illinois at Urbana-Champaign [1] http://www.pharo-project.org/home [2] http://www.moosetechnology.org/tools/glamour [3] http://splashcon.org/2011/ -- View this message in context: http://forum.world.st/ANN-Language-of-Languages-Demo-at-SPLASH-11-tp3910817… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

I think I am not the only one who is also interested in the conference, but can not go there in person. Is it possible to have videos from the conference?

Hi, EyeSee is a model for charts. The rendering logic is meant to be orthogonal.
