[Pharo-project] Issue 1554
Hi! I just uploaded my first fix (or so I hope) for Pharo to the Inbox as Ocompletion-DannyChan.44, following the instructions on the wiki for contributions. When selecting a text in a workspace including the first character in the window and hitting backspace, an exception will be thrown by ocompletion, because the smartBackspace method will try to look at the character before the current position of the caret, which is 0 in this case. The instructions on the wiki say to put the status of the bug report to fixed, but I saw no way to do this. Did I miss something? By the way, I want to thank all of you for the great work you put into Pharo. I am no software developer myself, but I really hope to be able to use it for all the little tools I need all the time at work.

Hi all, While migrating a preference for it I noticed that at least, it is not very well integrated in pharo...

The change was only made once, and the reason was to allow the FFI pools to be a separate package that could be loaded into VMMaker without requiring all the rest of FFI. WeirdI am sure I tested with FFI-Pool and in addition most people put the fix with FFI-Pool. But now that package does not exists, and it is FFI-Pools. But anyway, I am not saying Andres is guilty. I am in favor of the continuous refactor :) I did something similar when I put Speech on SqueakSource, so we can have only the necessary dependencies for VMMaker. Near term it is confusing to change packages, but gradually we are getting more modular :) Excellent!!

Re: [Pharo-project] Issue 1554
Hi Danny, Thanks for your contribution. Your change is in the package Ocompletion, which is outside Pharo- core. This package is maintained by Romain. I added Romain to CC so he can merge your fix into the main branch of Ocompletion. Cheers, Adrian On Dec 8, 2009, at 09:09 , Danny Chan wrote: Hi!

Re: [Pharo-project] New User Experience Suggestion for 1.0
Please note that there is an issue in the tracker that discusses this. I've suggested to add a workspace but do not add a long text and code but link to the pages on the web that contain it so that we can more easily make updates. http://code.google.com/p/pharo/issues/detail?id=1479 Tim, would that be helpful for new users of Pharo?

It's in 1.1 already, test does not fail there. Also, in Core testResetAfterEmphasized fails but it seems to have been removed from Dev. It's a malformed test though, as it tests for empty, when it is valid for the method to leave non-synthetic versions in the derived array after a reset (Which is the case for Bitmap DejaVu, which includes bold, italic, bold italic versions) I've rewritten that test to be more robust, issue 1556 with slice in inbox.

We attempted to segment off our font menu since it was expensive to build, and really only needed to be changed if the fonts on the machine changed. Since the image was read only we would startup, build the font menu then image segment that off. On a restart we just read the segment in, confirmed the machine didn't have font files changed. This worked well in the *lab*. But when we push it to the public we started getting email about machines crashing. Tim and I were just unable to determine why... But it was always related to the point where it read the image segment, sometimes it would crash (rarely) mostly not. We backed that out, and settled with a image segment that really just stored forms of each font face for the menu. That *seemed* to work ok Thanks John. I am interested in your experience. However, I didn't understand this last paragraph where you said to finally make it work. I don't understand what did you change. What is the difference between font menu and stored forms of each font face for the menu ? In addition, do you know why this has solved the problems ?

Ok...let me see if I understood you correctly. When you are creating your root of objects and you put symbols inside, they are not put in ourPointers but in ByteArray. This is due to the fact that the only object who is pointing to that symbol is inside the segment ? What you do with this piece of code: symbolHolder := Symbol allSymbols. is to hold those symbols there. So, when ImageSegment uses the GC techniques to detect which objects are ONLY pointed from inside of the segment, the symbols is not found (because it is accessible trough that test) and thus, it goes to outPointers instead of ByteArray. And of course, if it is in outPointers instead of ByteArray when the segment is loaded again, yo don't create a symbol again but use the same object (the one of the oop). I am correct? or I understood anything ? Cheers, Mariano BTW, Mariano is also writing ImageSegment tests, so maybe you want to join forces (or maybe he already is the colleague you mentioned?).

[Pharo-project] BUG: 'Error: Instances of UndefinedObject are not indexable' with Interpreter
Hi folks! I having this problem in pharo1.0-10496-rc1dev09.11.4 but I cannot reproduce it in PharoCore-1.1-11078-ALPHA I don't think it is because of the Pharo version but becuase of dev/core. I would like to tested in a dev from 11078 but the last one I tested was not working as I have warings and popups everywhere (there is already a thread for that). I am in Mac OS. Anyway, you can reproduce it in a fresh pharo1.0-10496-rc1dev09.11.4 image. Steps to reproduce: 1) Download from http://www.squeaksource.com/JBARepo the package VMMakerLoader 2) Evaluate VMMakerLoader loadAndFix 3) Browse the class Interpreter 4) Go to the method primitiveStoreImageSegment. Click on the method and after a second you will have this error.

Re: [Pharo-project] New User Experience Suggestion for 1.0
Can I suggest something like the following (all suggestions welcome - I am trying to have something that is welcoming as well as something that allows people to jump right in and try things, and/or then go to places with more complete documentation like others have suggested): Pharo+Seaside 1.0 RC1 (Title in bold if we can do this like the old Squeak one) Welcome to Pharo + Seaside, a clean, innovative, free and open-source Smalltalk environment aimed at both professional and recreational programmers alike. To get a quick feeling of what is possible with Pharo, open a browser with http://localhost:8080/seaside and explore some of the examples. To administer Seaside, this environment is configured with username: admin and password: seaside If you are curious and want to view some code behind these examples, single click on the background of the main window, choose Class Browser and type WACounter. You can then browse the methods for the simple counter and try modifying some of the code, live! If you are new to Smalltalk we recommended that you use this environment and follow the tutorial at http://pharobyexample.org/ Alternatively If you are interested in jumping straight into web development with Pharo and Seaside you can follow the tutorial at http://book.seaside.st/book Finally, have fun with Smalltalk, and make sure you follow the progress of Pharo at http://www.pharo-project.org Tim On 8 Dec 2009, at 08:23, Damien Cassou wrote: Hi Tim, On Tue, Dec 8, 2009 at 12:51 AM, Tim Mackinnon tamackin...@gmail.com wrote: Guys - do you think you might consider bringing back the little Readme Workspace in the final 1.0 image (or maybe 1.1)? there is no technical difficulty.

Re: [Pharo-project] can I debug a primitive?
That would be nice indeed. And you can do it if you simulate the VM, i.e., run the interpreter inside an image as Smalltalk code. To get the interpreter working may be challenging, though. I once had a working version and submitted some patches to Mantis. I don't think these were integrated, though. Also note that in the debugger you just see pointers and not objects, so even with the Smalltalk debugger it can get complicated to debug the VM.

Re: [Pharo-project] Dev09.12.1 does not look nice on Linux
The default fonts were changed, now Bitmap StrikeFonts are used instead of a TrueType font. Thus, the rendering method is completely different, and the use in StrikeFont rendering of some BitBlt methods revealed bugs in the alpha channel handling in said methods that previously went unnoticed. (Thus an updated VM/BitBlt plugin in required for them to render correctly).

Why a preference? Its just a matter of selecting the font you like:
System Preferences System fonts
In the Font Browser you can click on Update and you *should* get all
your system fonts. The problem is, that the font browser does not
update. If you open it again, you see the fonts.

Re: [Pharo-project] BUG: 'Error: Instances of UndefinedObject are not indexable' with Interpreter
2009/12/8 Henrik Johansen henrik.s.johan...@veloxit.no Although I'm unable to reproduce it, it seems to me the possibility of a situation where this error could occur increases if text compositing takes too long. (notice how primitiveStoreImageSegment is ). Reasoning; - In TextMorph paragraph, an uninitialized paragraph is installed in the instvar, then line composition happens. - If this method is called from another thread than the UI thread, (say, as a response to an Event, which seems to be the case at least for OB) it might be interrupted by the UI process, which will happily go ahead and try to render the paragraph before it is initialized, then throw an error since lines is still nil. A fix for this problem (which would be to create the paragraph in a temp, then store in instvar only when fully intialized) is attached. Wow!!! you are really the bug killer number one! Thank you very much. Not only I could reproduce it but also apply the fix and be sure it is fixed and working like a charm now. I commit SLICE-Issue1559 http://code.google.com/p/pharo/issues/detail?id=1559-UninitializedParagraph-MarianoMartinezPeck.1 to inbox. Cheers, Mariano If you would file it in and see if it helps, that'd be nice.

Why a preference? Its just a matter of selecting the font you like:
System Preferences System fonts
In the Font Browser you can click on Update and you *should* get all
your system fonts. The problem is, that the font browser does not
update. If you open it again, you see the fonts.
Excellent :) I wasn't aware of this! really cool.
I filed an issue for 1.0/1.1:

It should be explained somewhere how to replace StrikeFonts for

Or even better, a preference for that maybe be cool.

Would be nice to expose the technique used in FreeType for
underline/strikeout... even if only stub where rendered by a
StrikeFont.
Would help a lot for other canvas types (PDF, PostScript etc.)... For
instance, a P{DF canvas would draw the underline using graphics
primitives...

It uses pre-rendered sub-pixel fonts instead of rendering the
fonts via
FreeType.
(Much faster, not quite as nice in details).
Freetype fonts are available if needed, though. The pre-rendered
fonts
just replace
the 80ties=looking Squeak fonts and provide a good enough
selection for a
development image.

Hi,
I had the same issue with exupery vm. Works with VM
Squeak-3.11.3.2135.

Hi,
the last version's fonts look really bad. See attached files
I have Ubuntu 9.10, 64 bits.
Dev09.11.4 looks fine
Maybe is a preference setting?

Re: [Pharo-project] DeprecationHistory
2009/12/8 Alain Plantec alain.plan...@free.fr: Hi all, One of my recents slice for preferences migration has made pharo nearly unusable because a lot of deprecation dialogs was opened for a single browser. Then, the user had to forbid the deprecation warnings in order to avoid these popups. Now, what about a non blocking window which is opened automatically when a deprecated method is run, but showing the list of recents deprecations ? A double click on a list item, et hop!, a browser is opened on the deprecated method. I've tried it on the last pharo image and it seems ok. With it, it is still always possible to let deprecation warning without having to close any dialog window. What do you think ? A screenshot is attached. Cheers Alain +1 I like the idea...

Re: [Pharo-project] getting rid of Symbol new: ?
The chore of loading all 500 fonts on a macintosh, rendering them all to show what they look like, was *quite* expensive and added many 10's of seconds to Sophie startup time. At first we dumped the entire font menu oops tree into a image segment. The did a merge process by checking the current machine's view of the fonts, versus our historical view. usually fonts don't change much so the cost was only reading the directory. This worked oh, 99.99% of the time. The 0.01% was the hassle. Our fallback was then to store the rendered form for each font in an image segment. That seemed to work 100% As pointed out there is just a mess of eToys/Projects/whatever special casing going on in the default storage/reading of the segments, and when it goes bad, it's *hard* to figure out why. I did explore this area a bit more with WikiServer. In fact it's still on my to-do list, you can customize/override things to get a more simplistic set of steps, but I wasn't quite sure that sending a Pier Wiki to an image segment would be readable in the future, so I decided not to offer that as a storage option.

However, I didn't understand this last paragraph where you said to finally make it work. I don't understand what did you change. What is the difference between font menu and stored forms of each font face for the menu ? The way I read it, instead of storing the fonts themselves in an image segment, they stored a form with a string rendered by the font, then used that to display in list instead of actually loading the font, and rendering text with it. That way the list could be shown fast, without having to load the fonts themselves until actually used/fonts on the machine changes. In addition, do you know why this has solved the problems ? If you look at the relative complexity of TTCFont and Form instances, it'd hardly come as a surprise that one may be loaded consistently, while the other is harder to get loaded correctly in all cases... In other words, to me it seems like a workaround for non-repeatable errors when loading complex objects within ImageSegments (by storing simpler objects instead).
