[Pharo-project] Pharo on retina display
by Sean P. DeNigris Oct. 13, 2012

Oct. 13, 2012

Like all apps not upgraded for retina, Pharo looks pixelated and fuzzy on the new MBPs. Is there any workaround which at least makes the text less fuzzy? http://forum.world.st/file/n4642567/Screen_Shot_2012-08-01_at_3.48.23_PM.png -- View this message in context: http://forum.world.st/Pharo-on-retina-display-tp4642567.html Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Roassal Survey
by Vanessa PeÃ±a Araya Oct. 7, 2012

Oct. 7, 2012

Hello! As you probably know, Roassal was presented at ESUG. We received a lot of positive feedback from you and also a lot of request for features. Thank you very much! We want to start working on this, but also prioritize what seems to be more urgent. For this, we would like to survey the community about 1 - what are the features you would like to see in Roassal. Please, provide a list of features requests and tell us about their priority 2 - scenarios where you would like to use Roassal. Thank you very much, Vanessa.

[Pharo-project] Metacello bleedingEdge question
by Sven Van Caekenberghe Oct. 2, 2012

Oct. 2, 2012

Hi, I have a question. The following works as expected and loads the latest versions of the code: ConfigurationOfZincHTTPComponents project bleedingEdge load. The following does not and keeps loading only the #stable one and not the latest one. ConfigurationOfZTimestamp project bleedingEdge load. I can't see any difference, but I am a Metacello newbie. Has anyone any idea where I should look ? Thx, Sven -- Sven Van Caekenberghe http://stfx.eu Smalltalk is the Red Pill

[Pharo-project] Bad behaviour at startup
by Denis Kudriashov Oct. 2, 2012

Oct. 2, 2012

Hello. I found very bad behaviour. I use Pharo1.4. And when there is some errors at startup Image just closed. It is horrible I have image with seaside application which open socket at startup. So when I move to another computer where this port is busy (or closed by firewall) Pharo opened and immediately closed. No chance to debug and fix it. What you think about it? Is it fixed already at pharo 2.0? Best regards Denis

[Pharo-project] String>>includesSub[S|s]tring: - do we need another kind of deprecation ?
by Sven Van Caekenberghe Oct. 1, 2012

Oct. 1, 2012

Guys, So yesterday I deployed a new server based on an #20309 image, with a single Metacello config for my code, and a separate manual load for Seaside 3.1 (which I use as an interface to work with the headless image) - and all went well ! But I had to apply one manual hack: remove the deprecation from #includesSubString: (for Seaside). I feel like we need another, more silent kind of deprecation for situations like this. Library/framework/application writers targetting multiple Pharo versions are being hit way too hard by this, for - in this case certainly -, no good reason. Creating two versions (I introduced a special package Pharo-Forward-Compatibility just for this), is not worth it (unless you absolutely want the best Pharo 2.x code like I do). I would imagine something similar to Deprecation which maybe prints on the Transcript, but is otherwise silent, except when some switch is turned on. It would give us the power to deprecate much more things even 'silly renames'. And less external stuff would break. What do you think ?

Cool! Thanks Mariano for the summary, and all the others for this much needed features! Looking forward to adopt such a process, to have a minimal Pharo image, customized to my needs.

Anyway, what I wanted to say is that Fuel DOES WORK in previous images. In fact, it works from Pharo 1.1 to 2.0. And Tanker right now works in 2.0 only by just because by default we use the new ClassBuilder. But this can be easily changed for those who want to use it in older versions. Anyway, Tanker is still a little bit green ;) For more details read my answer to this comment: http://marianopeck.wordpress.com/2012/09/28/new-tanker-current-status/#comm… > > Hello and thank's for response. > > Actually I want use Tanker to deploy my applications with "bootstrap way" where only kernel minimal image existed and all application loaded at startup. > It will simplify delivering application updates to slow remote targets.

I want to say a couple of things about this. First, you are not the only one wanting this.

He is now able to bootstrap images from scratch (contrary to Pavel's PharoKernel where he was unloading packages). > 4) Esteban Lorenzano is working on a new ConfigurationOfPharo that will let you take a kernel/bootstraped/minimal image and load just the packages you want. > 5) Camilo Bruni, Martin Dias, Guillermo Polito, and Toon Verwaest have been working in a new class builder based on layouts. The "old ClassBuilder" is really difficult to maintain, understand, fix, etc. When you load packages, the class builder takes an important role. Therefore, they were working in a new class builder, which, from my point of view, is way better, object-oriented, tested, etc. > 6) Martin Dias and Me were working in Tanker, a tool to export/import packages of code using Fuel without Compiler. > > So.....as you can see there is/was a lot of work going on related to what you need :) It is not 100% ready, but we are getting there. > > Cheers, > > > Best regards, > Denis > > > > > > > > > -- > Mariano > http://marianopeck.wordpress.com >

You didn't look hard enough -- it's under the "help" menu. Squeak 3.0 is the earliest I have on my HD but.. yes, it was there then and its still there now. Ok, I know you just forgot we miss you too Igor. ;) I admire Pharo blazing new trails but notice a pattern in some of the "gold" feedback from Pharo customers which worth taking to heart. Like: http://lists.gforge.inria.fr/pipermail/pharo-project/2012-May/064702.html > This is, what i think, happens with shortcuts changes in Pharo, except > form those which was remapped. > >> Pharo favors _familiarity_ for new users somewhat at the cost of >> productivity for its experienced users.

I would rather have the best system possible than one with the most mainstream acceptance.
