[Pharo-project] Zinc-HTTP-Deprecated
by Sven Van Caekenberghe Sept. 5, 2012

Sept. 5, 2012

There is a class category called 'Zinc-HTTP-Deprecated'. It contains some old classes that were replaced/superceded by newer ones almost a year ago. I plan to actually delete these and their unit tests in a commit in the next couple of days. Specifically, the following classes will be removed: - ZnClientOld - ZnFixedClient - ZnExtendedFixedClient - ZnUserAgent - ZnHttpClient - ZnUserAgentSettings I hope nobody uses these anymore.

[Pharo-project] Some news about Athens
by Igor Stasenko Sept. 4, 2012

Sept. 4, 2012

I added a text support for Cairo backend.. unfortunately i was unable to force it rendering with subpixel AA, Cairo completely ignoring settings i passing to it (looks like i need to dig into compilation options to enable it) So, following examples contain simple code to draw text on surface: AthensCairoSurfaceExamples drawFontMetrics AthensCairoSurfaceExamples draw2Strings A following one is my current state of endless battle area with Morphic.. AthensTextRenderTest testWindowRender since morphic using absolute coordinate system, i can't make the clipping right no matter how hard i try arghhhh .. These changes are available if you load ConfigurationOfAthens v 1.4 But you might probably will unable to use it anyways ;), because NB-enabled VMs on jenkins are not yet bundled with cairo library.. I will do a pass on VMs this week and let you know when this stuff will be readily available for download and play with. So many things stacked on top of each other.. it is a pain the ass when something on base level breaks. -- Best regards, Igor Stasenko.

[Pharo-project] How to create a basic OS for the Raspberry Pi - VM+Pharo on top?
by phil＠highoctane.be Sept. 4, 2012

Sept. 4, 2012

Check http://www.cl.cam.ac.uk/freshers/raspberrypi/tutorials/os/ Now, how hard would it be to get a stack VM and an image running on top? Anyone looking at this kind of stuff in the community? Phil

[Pharo-project] Max CPU usage when #drawOn: is overridden
by S Krish Sept. 4, 2012

Sept. 4, 2012

If we override #drawOn: and implement custom logic to draw.. every few milliseconds as it gets called the CPU usage shoots to available max.. Run four instances of the same class that overrides and does some moderately complex draw routine of say : CircleMorph with border set, few lines, color rendering.. I will send in the .st file later .. that can be tested against.. Is this expected or what are the ways to avoid this CPU overhead... NativeBoost animation, far more responsive.. also goes up very similarly. but little more tolerable... VGTigerMorph... more so than FlakesDemo...

[Pharo-project] [NativeBoost] Question: zero-based or one-based indexes?
by Igor Stasenko Sept. 3, 2012

Sept. 3, 2012

Hi, there i added a bunch of accessors to ByteArray and NBExternalAddress which having uniform look: nb<type>At: nb<type>At: put: where types are: {U}Int<8/16/32/64> or Float<32/64> the problem is that indexes in ByteArray are 1-based, but in NBExternalAddress is 0-based. And there's already different places in code which following these rules. But i feel like this should be uniform (so same piece of code can be used for either bytearrays or external addresses), to avoid confusion and mistakes. i just not sure which one to leave: 1-based or 0-based ? >From one side, all collections in smalltalk is 1-based.. but from other side accessing memory at 1-based offset looks also unnatural. What you think? -- Best regards, Igor Stasenko.

[Pharo-project] A useful set of Smalltalk-like methods for Objective-C
by Oscar E A CallaÃº Sept. 3, 2012

Sept. 3, 2012

Hi all, I just release a useful set of Smalltalk-like methods (eg. collect: or match: ) for Objective-C classes NSArray, NSMutableArray and NSString. I just extends those classes using categories and blocks. I made this, because when programming on Objective-C, I really miss them. You can find those methods on: https://github.com/ocallau/ObjCSmalltalkExtensions They are in an iOS project, but you can use them in OSX too. Of course, they come with a set of unit tests (on GHUnit). I hope these methods can be useful for you, as they are for me. Cheers. Oscar

[Pharo-project] What happens with Warning when running in headless image (2.0)?
by Dale Henrichs Sept. 3, 2012

Sept. 3, 2012

I'm running a headless pharo2.0 from a script and the vm disappears without a trace (no pharodebug.log info etc.) ... when I run the script in a gui, I see that a warning dialog box is popping up, so perhaps this is the source of the issue? ... or perhaps it's something else? Dale

[Pharo-project] [NativeBoost] 1.4 Bleeeding edge release
by Igor Stasenko Sept. 3, 2012

Sept. 3, 2012

Hi, i was in a mood of making some overhauls.. so as result i refurbished a type system a bit.. removed all bogus C-like class names , e.g. NBUnsignedIntType ... and replaced them with nice and uniform names, like NBUInt32, NBInt16 etc. (thanks Marten Feldtmann for an idea) A uniform type aliases for these types also added: int8 NBInt8 uint8 NBUInt8 int16 NBInt16 uint16 NBUInt16 int32 NBInt32 uint32 NBUInt32 int64 NBInt64 uint64 NBUInt64 the rest of C integer types are actually aliases of the above. And some new features: - finally spent time for implementing support of 64-bit integer types. (strangely over 2 years nobody needed them ;) - added a bunch of uniform accessors to ByteArray and NBExternalAddress. But please avoid heavily depending on using them right now, before we decide whether they should use uniform indexing, or stay 1-based index for byte arrays, but 0-based indexes for external addresses. And if we decide to have them uniform, should they use 1-based or 0-based indexing. May be force with you. P.S. The configuration is freshly-baked, i didn't even checked if it loads cleanly or not.. so, i don't recommend updating it in image with your precious code :) Special instruction to load NB for Stef: Gofer it squeaksource: 'NativeBoost'; package: 'ConfigurationOfNativeBoost'; load. (ConfigurationOfNativeBoost project version: '1.4' ) load P.P.S. i would really like some help with testing what i did, including writing some more tests to cover type system more broadly (now since type names follow certain naming rule, many different types can be checked without much coding) -- Best regards, Igor Stasenko.
