Is there a way to ask for a set of project names under a given Team/User? I don't like maintaining lists like this one: #( 'BitmapCharacterSet' 'CollectionArithmetic' 'Coral' 'EventRecorder' 'FFICompatibility' 'FileSystemLegacy' 'Flotr' 'Gettext' 'ImageWorker' 'JSON' 'LDAP' 'LEDMorph' 'MorphExamplesAndDemos' 'NBOpenGL' 'OPAX' 'OrderPreservingDictionary' 'Pastell' 'Phexample' 'PlotMorph' 'PostgresV2' 'Postmark' 'ProfStef' 'RFB' 'ROE' 'SCouchDBViewServer' 'SMark' 'Smacc' 'Sound' 'Soup' 'Spotlight2' 'Tanker' 'XMLParser' 'XMLSupport' 'XMLWriter' 'XPath' 'readline') do: [ :projectName | MCRepositoryGroup default addRepository: ( MCSmalltalkhubRepository owner: 'PharoExtras' project: projectName) ].

Re: [Pharo-dev] Pen back in the image

by jannik laval

Hi Phil, There is a Pen in Phratch, named PhratchPen. You could probably extract it. There is also an editor. I discover last week that some command in this editor does not work, but the main feature is here. I am thinking that we can extract it too.

Pen back in the image

by phil＠highoctane.be

Hello, I'd like to see the Pen class coming back in the main image. It really is useful for getting people acquainted with the tools and the bluebook uses it. I am not asking for a form editor (it could be handy though). Path is dead as it was hijacked by FileSystem. I miss it too. What do you people think? Phil

That's enough setup. Now for the suggestion.

This is something what called V-Sync. And all i can tell about it, that it is out of scope of Athens, because there's nothing in Athens API which tells where the results of drawing will be used: on screen, printed on paper, into file etc.. Dealing with it requires another device-specific layer which controls it, in our case - the layer responsible for delivering content to the screen. Apparently for such layer (if it will appear one day - like in OSWindow), it should be completely orthogonal, where content comes from: from Athens, BitBlt or other source(s).

I can't miss it with AltBrowser, and it's visible in Nautilus, but not in Browser. Strange, I just filed in that .st file when integrating. This should normally not create any packageâ¦. Marcus
