[Pharo-project] Bug Report: 3 of 6; Image freeze
by S Krish Jan. 7, 2012

Jan. 7, 2012

3. Image Freeze: Anything that hits #fullBounds with a byteString instead of a Morph does not simply handle it... but freezes. This occurs with an external Table Morph Package that permits constructing a grid of morphs, but if you pass the 'string' instead of 'string' asMorph.. it takes it.. but when opening freezes similar to if we put a break point on Morph>>fullBounds/ processEvent:using: ... Alt . with an image that has Sound package loaded, causes a dialog for choosing a Sound Package that is all disabled and freezes the image

[Pharo-project] Pharo by Example
by Gerry Weaver Jan. 7, 2012

Jan. 7, 2012

Hello All, I'm new to Pharo and SmallTalk. I am trying to follow "Pharo by Example", but my Pharo browser is not the same. I tried to follow the FAQ about how to fix that, but the drop down menu doesn't look the same either. Should I be using a different version of Pharo? I'm using 1.3. Thanks, Gerry

[Pharo-project] Smart bracketing annoyance
by Ben Coman Jan. 7, 2012

Jan. 7, 2012

I am still coming to terms with the "smart" bracketing where pressing the open-round-bracket key also produces a close-round-bracket, but I'm working on adapting. One thing that is ultra-annoying and that could be smarter is where for instance, being new to Smalltalk, I have got my round and square brackets mixed up preceding an ifTrue:. So I highlight the open-round-bracket, press the open-square-bracket expecting it to be replaced (like every other system I've dealt with) and surprise* now I've got the original round-bracket surrounded by two new square-brackets. If it instead found the matching close-round-bracket and changed both round-brackets to square-brackets, that would be cool rather than frustrating. The same applies to trying to correct string quotes and comment quotes. I hope that sounds reasonable and it would nice if it could be changed. cheers, Ben *surprise - not good for people new to the software you are trying to impress

Thanks Alain for trying it out. More user experience means better feedback for further code improvement. > - keyboard improvements : no way to get alt or ctl key working so far Some code for keyboard support has been written since, but maybe it was not included in the pre-generated apks. Once I add more features, I'll release another apk. And sources (on gitorious) are always there for those wanting to mess with Android build tools ;) > - new theme for tablet (bigger fonts, bigger scrollbars etc) (I started to > look at this) Yes, this would be nice to have. And take a look at Honeycomb/ICS: maybe some ideas may be learned from their GUIs. The new trend seems to be to expose additional controls somewhere on the screen once the context for them is right * (e. g. when a downloaded file is selected by touching, icons to delete or share it appear somewhere). Also see the new gmail web interface. > - new smalltalk tools : browser, finder inspector (I will try a small > Glamourous browser ) It would be nice if a smaller base Pharo image could be built such way, so it could be embedded with VM and distributed together. > - reduce cpu usage (suspend/awake pharo process ? ) I think Android takes care of it itself: once an application is invisible it is suspended automatically. Or did you notice any performance degradation? > - interface to android content providers (audio, video, calendar data etc) Working on it ;) In fact, there is a (partial) interface to the intent system, so a home screen shortcuts can be added to start CogDroid with given image and startup arguments. Reading from Android clipboard has been committed to the HEAD (but there is no support via context menu yet). Thanks again. ------------------------------------------------------------------------------------------------ * That is, when e. g. a text edit box is active, items of the context menu appear somewhere on screen. Maybe halos could be revived with this new meaning? -- Dimitry Golubovsky Anywhere on the Web

Eliot, I'm getting an external library not found error on Ubuntu lucid with the Cog vm from http://gforge.inria.fr/frs/download.php/29042/CogVM-Unix-13307.zip The library lives in /usr/lib and is known to ldconfig by the name that I have specified in #moduleName. What do I need to do? Bill

Hi, I saw responses from several people, will answer to everybody in a single message.

Not yet, but you just reminded me that it exists; eventually I'll try it out ;) Alain Rastoul wrote: > And if yu have an APK that I can download somewhere else than on the market, I never put CogDroid on the market - it is in google code. > I am interested > (the ALT and CTL key missing are really painful, I use the blue/yellow > button emulation but it is not cool) Give me some time to finish locale support, and I'll put some apks to a temporary location (other than google code - downloads in google code are unremovable). Keyboard modifiers work fine in x86 Android, but I just don't have any ARM device with keyboard to test it. > I am not sure the image size is really a problem on a tablet ? > lot of games - angry birds game (free on android market ) for example- are > about 30MB if I m right, It is more about the fact that bundling an image together with apk makes the image immutable. Such approach would be good if a specific application is shipped, or to have a "starter" image that provides a more convenient framework to download/upgrade other images than just doing that in Android browser. > I clearly had the feeling that the battery is going down faster when I use > Pharo perhaps because not all Smalltalk processes are sleepng and so the vm > never sleep ? > The UI morphic process make pauses of 20 ms when there is not event , I > don't know for others processes (Timer event loop, Input events process). > I have to investigate Have a look at this file: http://gitorious.org/~golubovsky/cogvm/dmg-blessed/blobs/master/platforms/a… methods of interest are timerEvent, and every method that calls it. The timerEvent method spawns a thread which generates a predefined (or infinite) number of timer events with given interval (timerDelay which is hardcoded as 200ms). But when interpreter returned by interval timer (this is necessary to have Android runtime poll for events), it will be reentered immediately beause there is some unfinished business. If user input is received, additional timer threads will be spawned, for limited amount of events generated. I may set this timerDelay to much larger value. But then VM will be frozen until any user input arrives - even server mode flag won't help. Even cursors in text inputs will stop blinking. Maybe this timerDelay has to be configurable if battery life is a concern. > Cool, if the clipboard vm primitives are ok, the System Clipboard class > should work ?. Not yet. All I have is a primitive that reads from Android clipboard (maybe I need to add one that writes there), but it has not been integrated with the rest of the image (and such integration is not really part of the VM). Perhaps a pair of items has to be added to the text editing context menu to copy/cut to and paste from Android clipboard. Schwab,Wilhelm K wrote: > Does an Archos 43 count as an Android device? I bought it with plans that fell flat (the target moved, and the OS was a little disappointing). That said, I have it and can > help with testing. I do not have a data plan for it, so my default usage is to copy packages to it via USB. I think it counts, but AFAIK is has 4.3" screen, correct - sized more like a phone? But technically you should be able to run CogDroid on it given enough RAM is available (someone I remember tried it on a phone with 128M RAM and that was not sufficient) 256M should be OK. If you have wifi on the tablet you should be able to hook it up with a home wifi router - only you need to have NAT enabled since Android browser does not use HTTP proxy. Pharo can be configured to use a proxy though so you can access Monticello repos also such way. > It is hard to imagine developing on it, but I'm willing to be pleasantly surprised, and it would be nice to be able to deploy Pharo apps on hand-held devices. You may develop on a PC and then transfer the image to the tablet. Or load packages from Monticello repos as usual (with proxy or NAT). Ben Coman wrote: > Consider getting a Jenkins build going with an Android emulator. Sounds interesting if I could set up build jobs for CogDroid if there are Android build tools on Jenkins. Hopefully I haven't missed anythng - feel free to ask more questions ;) Thanks. -- Dimitry Golubovsky Anywhere on the Web

Hi guys I thought that XMLSupport was about parsing and XMLNode traversal. So why the configuration contains references to SIXX and Grease Core? Stef

[Pharo-project] What should be in a configuration?
by Dale Henrichs Jan. 6, 2012

Jan. 6, 2012

Obviously, this post is inspired by the 'About ConfigurationOfXMLSupport' thread[1] on the pharo list. Many of the issues with ConfigurationOfXMLSupport are mired in a history that goes back to the very beginnings of Metacello. In the end ConfigurationOfXMLSupport is what it is... When it comes to what should be in a configuration, my opinion is that each project on SqueakSource should have a configuration. If it is worth having a separate project on SqueakSource, then it is worth having a configuration. Yes, even if there is only one package in the project it should have a configuration. The reasoning is simple: - projects evolve over time - as projects grow, eventually it makes sense to split the project into multiple packages - as projects grow, they are ported to other platforms and not all ports can be done without writing some platform specific code that needs to be packaged in a separate package - as projects grow, they become dependent upon other projects ... - over time the support for a project on VERSIONS of a platform change. Support is dropped for one version and added for another - over time the project API changes and not everyone can immediately move to the new API - over long enough periods, projects move from one repository to another Configurations were invented to address these problems and some of these problems exist no matter how many packages or dependent projects are involved. If I use a configuration to load the code from a project, all I have to worry about is which version of the project I want to use. When I see a new version is available, I can control when I load that new code and be assured that the code won't move out from under me ... Remember the message from the Metacello presentation that Mariano and I gave at ESUG 2010[2]: Configurations are NOT for the DEVELOPERS of a project but for the USERS of a project Dale [1] http://forum.world.st/About-ConfigurationOfXMLSupport-td4244103.html [2] http://www.youtube.com/watch?v=zWHS5xIo_xI&feature=youtu.be&a
