[Pharo-project] A .mcz of Pinesoft's accumulated fixes applicable to Pharo
by Simon Kirk Oct. 7, 2008

Oct. 7, 2008

Hi all. Gary and I decided we ought to give out an MCZ of our fixes that we've put together over the last two years. Obviously some of those we found have been pulled into Pharo already, but the attached MCZ represents those that we think are still relevant :) This is a rough list of the fixes: 1. Fixed flaky borwser comment text area sometime not showing. 2. Added getArgumentPermutation to support RefactoringEngine. 3. Fixes to CanvasCharacterScanner and MultiCanvasCharacterScanner to correctly align the first line of text when centered/justifed etc. 4. Added more constant names to Character class. 5. Modified ConnectionQueue to not accept connections when queue is full. 6. Changed GrafPort to answer a MultiDisplayScanner when appropriate (allows subclasses of MultiNewParagraph). 7. NaturalLanguageTranslator startup postion move to after PasteUpMorph since it will show a progress bar. 8. Fix to Random>>nextInt: to allow large numbers which would be out of range if using Floats (as mentioned recently on dev, use of Floats is dodgy anyway...) 9. Changed TranscriptStream>>clear to use a new buffer (was just reset which could leave a massive collection). 10. Changed RemoteString to handle concurrent processes safely. This one's particularly interesting: we were load-testing our Seaside app here and getting lots of syntax errors when hitting the image with around the 20 concurrent processes due to source file access. After this change we were hitting it with approximately 500 concurrent processes, and the failure was in the Java load tester (it timed out). Hope just submitting a .mcz is OK! :) Cheers, Simon and Gary ****************************************************************************************************************************************** This email is from Pinesoft Limited.

[Pharo-project] SIF working - needs a small fix
by Bill Schwab Oct. 1, 2008

Oct. 1, 2008

Hello, I would like to tell you all the incredible things I did to get SIF going - truth is, it loaded and just worked. The only gripe I have is that the Pharo browsers are displaying a large number of LF or other non-printable characters as boxes in the Pharo browsers. I have seen Squeak do this many times, and either just ignored it or deleted them, as my need to view the code and tolerance level allowed. It will get old with the amount of code I plan to move. How would YOU fix this? Is it a SIF problem (dumping out things it should not from Dolphin), a SIF problem (not supressing characters as they are loaded in Pharo), or something missing in the browsers that is expected to be fixed in Pharo?

Re: [Pharo-project] OSProcess under Pharo
by Bill Schwab Oct. 1, 2008

Oct. 1, 2008

Bryce, Thanks for your reply. Actually, I mentioned FFI etc. because that appeared to be a way to get what OSProcess wanted in terms of dependencies; using Universes should handle that part for me. FFI would be of interest on its own, but appears to make people nervous. Is that for good reason? Put another way, if I want to make some calls into a dll/so, do I really need to mess around with creating/compiling/distributing a plugin? It seems like a lot of overhead, especially since Dolphin does such a nice job based on a mechanism very similar (in apperance at least) to FFI. That said, I am interested in candid opinions; maybe things really are different in Squeak/Pharo. Thanks! Bill Wilhelm K.

I load OSProcess and FFI from universes, it works loading into a recent pharo-dev image. There's an issue with CommandShell as it subclasses off some MVC classes, I think it's safe to ignore. I'd load VMMaker from SqueakSource directly, but it depends on what you want to do. I've merged the FreeType changes into the Exupery VM's and will add closure support in the next few days. Loading Exupery-dev from the universes will load all the packages you listed. (Though, there's an incompatibility between Exupery and the stricter instance variable checks in Pharo, will be fixed in the next release.)

Before doing something I might regret, I wanted to check with you about installing OSProcess, VMMaker(?), FFI, etc. Do you have anything to say "try it and report any problems?" Bill Wilhelm K.

[Pharo-project] OB's icon support improved
by David RÃ¶thlisberger Sept. 30, 2008

Sept. 30, 2008

Hi there, taking the suggestions from the "On icons" thread, I have now changed and extended the icons in columns like this: - Removed icons for extension methods ('+'), instead use italic font for the method name label if it's a extension method and additionally red color if it's an override (as Lukas suggested) - Use new icons for abstract method and super send (credits to Stef who did the hard work of drawing them). The new icons make clear whether an abstract method or a method sending super is redefined in subclasses or not (they get an additional triangle pointing down if they are redefined). For a complete list of supported icons see: http://smallwiki.unibe.ch/hermion/icons/ There are still some icons missing for rare situations, if someone volunteers to draw them, we'd be happy. ;) - Explaining labels for all icons (keep the mouse over them) - Most icons are clickable: Clicking on a super send icon brings you to the method in the superclass, clicking on a triangle down icon brings you to the overridding method in the subclass or gives you a list of candidates if there are several sub-implementations. This I consider as a very convenient extension. - Classes or Traits can implement the method #browserIcon (answering a symbol for the icon name) to define the icon they will get in the class column themselves If you have more suggestions or wishes concerning icons (or anything else), let me know. Current ideas include to introduce icons for trait classes and methods (trait methods are shown in italic right now, hence somehow conflicting with extension methods), or to have an icon for methods without any additional implementor. I would be interested to know whether you consider these ideas as valuable. To load the latest version of OB, you can use this Installer script: Installer wiresong project: 'ob'; install: 'OmniBrowser-dr.419'; install: 'OB-Standard-dr.355'; install: 'OB-Morphic-dr.57'; install: 'OB-Enhancements-dr.217'. Cheers, David

[Pharo-project] Fwd: [Seaside-dev] preliminary Seaside 2.9 alpha universe
by Adrian Lienhard Sept. 30, 2008

Sept. 30, 2008

The new and easy way to load Seaside takes up to 10 steps (see below). We should try to make this even less painful in Pharo. I assume, having Universes pre-loaded will already reduce half of the steps, but how can it be further simplified?

Hi david in the latest version of pharo when you browse the senders of a message you get the usual list but the items show in addition the package in the item after the category (which is useless to my eye). Could you add that to OB senders and implementors? Stef
