[Pharo-project] Squeak in the web browser

by Pavel Krivanek

Hi, I was successful in running Squeak virtual machine on JSLinux. JSLinux is a x86 PC emulator written in JavaScript and running in a web browser. It required to compile the VM for uClibc and do some little modifications. So Squeak can log the next crazy platform where it is able to run :-) Unfortunately it has no display support and JSLinux license doesn't allow to make the work public but at least you may look at a short video: http://www.youtube.com/watch?v=mclkVePwNqE Cheers, -- Pavel

by Esteban Lorenzano

Hi, thanks for feedback... some answers: 1) If you use one of the latest VMs (https://ci.lille.inria.fr/pharo/view/Cog/job/Cog-VM/Architecture=32,OS=mac/…) you will have a nice full-screen mode button which works like any other full screen mode in mac. For now, you need to use that button. I will change the full screen mode primitive to behaves like that probably soon :) 2) You still have the halos, but you need to press ctrl+shift+click (in mac) 3) You can disable code completion in the Settings menu (at least in 1.4... I don't remember how it behaves in 1.3) 4) Yes, we need to improve how workspaces reflect system changes and property changes... you are completely right with that :) Hope this solve some of your problems...

Re: [Pharo-project] Some user interface suggestions

These are the kind of productivity:usage details (e.g., counting gestures, measuring effort) that need to be analyzed. Your feedback is like gold, Jeff.

Being able to toggle full-screen is really nice because it allows a feeling of "immersion" in whatever work you're doing. I sometimes use Pharo I hope they will consider emulating Squeak on this -- an always-accessible button neatly integrated into the interface. Unfortunately, I have the same issue with Alt+Tabbing to other windows -- never could solve that, which makes the button all the nicer. > 5) There are some awkward bits to the programming-specific input.

For all pair notations (e.g., quotes, double-quotes, brackets, curly's, parentheses, etc.), -- you can highlight the section you want and press the appropriate key for the pair you want. For example, highlight a section and press Command+[ to surround it in brackets. However, for the scenario above, I guess you said you wanted to remove a pair of of brackets and put them somewhere else. Unfortunately there is no easy way to do this in Pharo, but if Pharo would consider to emulate Squeak's handling of this, I think everyone could benefit. In Squeak, highlighting the innards of a pair allows you to *toggle* that pair on and off. So, to remove brackets, you just highlight to the inner edges of one of the brackets (either double-clicking or pressing Command+Space there), and then press Command+[ and the corresponding bracket pairs are removed. ALSO, in Squeak the selection is left undisturbed so you can immediately place a different pair, overtype, copy, exchange, whatever. I wish Pharo would do this too so that whenever I use Pharo it would be easier. > PS Overall, I'm pretty happy with Pharo. It definitely has fewer rough edges > and a smoother interfaceÂ than Squeak. That's important for my students. Squeak developers are continually improving the Squeak UI so if you remember what some of the rough edges were, we'd love to know on squeak-dev. Regards, Chris

[Pharo-project] Some user interface suggestions

by J.F. Rick

Hi everybody, as you might remember, I'm teaching Pharo in an introductory class. I'm finding a few rough edges with Pharo and was wondering whether people could help me. I'm using Pharo 1.3 with the CogVM on Mac OS X Lion. One problem I have is with fullScreen mode. First, I could no longer figure out how to go into fullScreen mode from the menus. Is this something that Pharo users don't do? If so, that seems a real shame. I then used the command (Display fullScreen: true). That worked, but, when I'm in fullScreen mode, I can no longer Alt-Tab between applications or workspaces. Is this a CogVM problem? Is it just that that's no longer the accepted way to go into fullScreen mode? In the class I'm doing live coding, basing a lot of stuff on showing something in a Workspace and having students work on problems to print to the Transcript (we are still on very basic for loops and have a while to go before they can use the browser to create classes). I use the Workspace to just list the things that I want to cover on that day. This is a mixture of plain text and code snippets. Kudos on being able to employ native fonts.

[Pharo-project] We need your Pharo successes

by StÃ©phane Ducasse

Hi everybody We really want to build a "vitrine" showroom of Pharo and we would you to participate. We want to build a web page with all these successes and show them to the world. :) We would like to get from you a three slides document: slide one: a sexy picture and a teaser / who you are. slide two: what is it how cool is it. slide three: what cool pharo techno you used or developed. If you have two successes then do two set of slides. So can you please send us these three slides. We would like to present them during the Pharo conf and after put them on the web. Stef and marcus.

Re: [Pharo-project] I cannot see the code in the latest Moose build

Now, I switched the build process to use as a seed, the fixed Nautilus image built on May 4. This means that, at this point, in the Moose image Nautilus does not get updated anymore.
