[Pharo-project] Happy new year..
by Krishsmalltalk Jan. 1, 2012

Jan. 1, 2012

Wishing all Pharoer's a very warm n happy new year Since last few weeks, I have been experimenting with Pharo as a tablet interface inside a tiny core Linux. The dev though happens on ubuntu. Some more playing around for a group of trainees with pharo on windows 7, platform I do not very much like. How far is it a nice to have framework that provides for a complete UI, IDE like a tablet interface and behaves akin to android that has it's own AppStore, and application launcher in full screen on icon click. Anyone can download the base, and proceed to download the app source, files archive thru an app installer, that verifies , validates and installs as well as creates a launcher icon ( I will provide the screenshots once I have them fine tuned) Rest of ideas and process are similar to android marketplace or iStore, with definite controls on absolute stability and experience of the apps Some observations i will like the veterans to clue me on forward . I find Pharo 1.2 more stable than 1.3 latest... . Is morphic capable of supporting error free runtime GUI I enjoy it's capabilities, but feel it demands more intrinsic Pharo, debugging ability to keep hacking n fixing. Crashes , damaged rectangle painting are just few of the troubles I expect a simple answer, not necessarily a longer explanation of morphic and it's issues with global coordinates, polling event handling which are nuisances. I have read thru as much of links, docs on morphic as i could find, little working on it, but not enough to get an expert hang of it. . Is system browser the best to study for morphic or should I look through any other package..Debug n learn.. . Simple way to get an embedded submorph from it's chain by it's name, #subMorphNamed: does help but only in a limited way.. For those that it digs. . Simpler way to bar extensions from a contributed older package, overriding base class methods, not really the final as in java but at least prevent overwriting methods. A listing post file in of uncompiled methods of this kind. Hacking in FilePackage does help.. But anything better and more complete...and part of a base system. . Mechanism to autosave a defined package every method commit to a packagename.mcz by default to ease crash recovery, use monticello only when I need to version it as a done base. . Event handling of mouseLeave mouseEnter of a PluggableTextMorph, the on:send: did not work, not that I have dug into it... But would like to link it to the models methods directly in the builder method interface like we do for PluggableButtonMorph click.... . Color of a morph is not updated when selecting it thru the halo. Minor hack i have here, to get thru. . Why is extent attribute not updated when we use addMorph:fullFrame: which changes the bounds for the submorphs in some cases at least as i have noticed in debug step thru. . What are clear do not do rules in using morphic framework as it exists today, as people have already experienced and attempted. . Debugger stepping through has most times an out of step highlighting. Any fix on this.. . Settings window seems to have glitches in network settings, font updates from OS... . Autocompletion in windows seems to work on cr, but in Linux you have to type thru. . The easiest way to have a core Pharo runtime image stripped of all dev tools, classes, size is not the limitation here, but stable n bug free base is a must. . Tools n tips to make Pharo base with its loaded apps crash proof, just isolate and close the app that causes the problem rest of the image should continue to run. issue not directly related: . Windows support for OSProcess, i have read the threads and the note from Eliot that it works on windows for cadence, but I cannot get it to work, the ProcessWrapper works but is limited. If I do get it working does it support interactive shell, viz i invoke a command that enters into it's own loop of inputs n output till you send a quit. Lots more i will come up with in the next couple of weeks as I bring out what i have. Sudhakar krishnamachari Extn 91-40403012 Cell 9902104814

[Pharo-project] feature request - undo closed tab
by btc＠openInWorld.com Jan. 1, 2012

Jan. 1, 2012

Neglecting that in 6 months I might be in a position try implementing this myself, here is a feature request in case anyone likes it enough to implement it in the meantime, or who can advise why it is a bad idea. Background: For me, one of the greatest most useful features of web browsers is the "Undo Close Tab." I browse almost exclusively opening all links as new tabs since I find this the fastest to follow diversions and then return to my previous place up the stack of tabs. I can get 20 or more odd tabs in a browser window. When I'm speedily closing tabs to backtrack my position, I find my recognition of content often lags my tab closing by a split second. Being able to un-close that last tab is a lifesaver. Now that I am getting into actual programming in Pharo, I have found that from time to time I've ended up with more than a dozen tabs in the "task bar" at the bottom of World. A few times already when I've flicking through these closing them after finish a line of thought, I have accidentally closed some tabs that I wanted to keep - like the Workspace I had been using as a bit of a history log. Perhaps my workflow is bad - but I really miss being able to Undo closing that last window. Features: 1. For a window that has a tab on the "task bar" at the bottom of World, when it is closed allow it to be reopened in the same state. 2. Clicking on the "Task bar" provides a menu item "Undo Close Tab" that either: 2a. Brings back the last closed tab. 2b. Provides a "restore list" of previously closed tabs sorted by time closed, which brings back that tab. Implementation Idea: 3. When closing a tab, rather than actually closing it, the window is just minimised but is removed from the tab and placed on the "restore list". 4a. The "restore list" is a certain length and when a tab is bumped off the end it is properly closed. 4b. Alternatively tabs may remove themselves from the "restore list" after a certain timeout eg 30 minutes. I'd appreciate your thoughts... cheers, Ben

[Pharo-project] System Browser - shifting class comments into pane beneath class definition
by Ben Coman Jan. 1, 2012

Jan. 1, 2012

I could not find any previous discussion of this so I'll just throw this out there... I find that I forget to click the "?" button to read the class comments as I browse around the system. They are "kind of" hidden. Perhaps also I stop looking because they are often empty. If others do the same then it is a downward spiral... if it seems no one looks at them then no one values writing them. (Except for the good work of the COTDC) However System Browser opens by default with 16 lines. Most class definitions (eg [1]) use 6 lines, which leaves a lot of unused whitespace. I wonder if the class comment was to appear (in a separate pane) beneath the class definition then the class definition would be filled out more often. Bring the class comments to the fore and perhaps they'll be valued more. At least for me, it will ensure that I don't miss where there are good comments I can learn from. Also more attention may focus on the poor comments due to being more exposed. just a random thought... cheers, Ben [1] Object subclass: #Behavior uses: TPureBehavior instanceVariableNames: 'superclass methodDict format' classVariableNames: 'ObsoleteSubclasses' poolDictionaries: '' category: 'Kernel-Classes'

[Pharo-project] Possible bug in FFI
by ncalexan Jan. 1, 2012

Jan. 1, 2012

Hello all, Long-time reader, first-time poster. Is FFI fully supported on Pharo? I installed into the 1.3 OneClick using Gofer new squeaksource: 'MetacelloRepository'; package: 'ConfigurationOfFFI'; load. ConfigurationOfFFI load. All seems fine but ExternalAddress gcallocate: 128 fails in ExternalAddress>>shallowCopy, complaining that clone is not understood. Bug? Not supported? Misused?

[Pharo-project] Good practicces! Looking for examples
by StÃ©phane Ducasse Dec. 30, 2011

Dec. 30, 2011

Hi guys talking with sven during the last sprint we realized that it would be good to collect and document some good practices. So I started a chapter for PBE2 on coding practices. I will take the some of the optimization that sven did in time/date printOn: as a start If you have some suggestions with examples I could integrate to the chapter. Stef

[Pharo-project] Classes referenced in code string
by Sean P. DeNigris Dec. 30, 2011

Dec. 30, 2011

How would I programmatically find out what classes are referenced in a string. For example: 'Object new. String new' "would return { Object. String }" -- View this message in context: http://forum.world.st/Classes-referenced-in-code-string-tp4244214p4244214.h… Sent from the Pharo Smalltalk mailing list archive at Nabble.com.

[Pharo-project] Packages and Pharo and Portability : the 3 Ps !
by Torsten Bergmann Dec. 30, 2011

Dec. 30, 2011

Hi Stef >For pharo > >this is simple: create a configurationOf and publish it in >MetacelloRepository. Yes, http://www.squeaksource.com/MetacelloRepository is the common repo for the configs. >I do not have the cycles to put in place what I wanted for >Pharo1.2, Pharo1.3 distributions i.e. specific MetacelloRepositories >per version so if somebody wants to really get an impact for >Pharo he should contact me and we can discuss about the next steps. The step is simple: open the MetaRepoForPharoXX so we can copy the configs there too! If one of these configs is known to work in Pharo 1.3 it should be copied using the "copy" button of the metacello browser to the www.squeaksource.com/MetaRepoForPharo13 repo and it will automatically appear in the Configuration browser for easy load. Something like a Universe for 1.3. Unfortunately the www.squeaksource.com/MetaRepoForPharo13 is "read" only. I already asked Marcus to add me as a developer. Best would be if it would be public write. Bye T. -- Empfehlen Sie GMX DSL Ihren Freunden und Bekannten und wir belohnen Sie mit bis zu 50,- Euro! https://freundschaftswerbung.gmx.de
