[Pharo-project] Why Sets need to be rehashed when loading them from an ImageSegment?
by Mariano Martinez Peck Jan. 11, 2011

Jan. 11, 2011

Hi. I was almost sure that Set instances that were written in an ImageSegment, needed to be rehashed once they are swap in. And I even thought I was understanding why. But now, I don't understand at all why is that. I would really appreciate anyway that can give me a hint. So...ImageSegment rehashes all Set instances (at loading time) that were written in an ImageSegment, and then exported with ReferenceStream. Notice that this rehash is finally called from ImageSegment >> comeFullyUpOnReload: smartRefStream. When you export an ImageSegment with a reference stream, you also serializer the "outPointers" array. This is usually the case when you want to load the object subgraph in another image or when do it backups so that to start with a clean image. Notice that the Set rehash only occurs in this case. If we use ImageSegment just to swap out / in, there is no Set rehash. So...I think that this has something to do about WHY Set instances need to be rehashed. For each object ImageSegment write into the file, it writes both: object header + slots. So....the hash (12 bits in the object header) is copied. When the object is loaded back, it continues to have the same hash. It doesn't change. So...if hash doesn't change, why Set instances need to be rehashes when they come back from an ImageSegment? Thanks in advance, Mariano

[Pharo-project] Pharo/Seaside UI testing
by Tony Fleig Jan. 11, 2011

Jan. 11, 2011

I have to say, I am loving the Pharo/Seaside development environment. Manually testing TFLogin (a basic login and user account management package for Seaside) using Firefox was taking longer and longer as added features multiplied the number of cases to be tested. I had unit tests for the underlying pieces; testing the callbacks on the rendered pages was where most of my time was being spent. Yesterday I loaded WebClient and Soup from Squeaksource and together they made it possible for me to script tests of the TFLogin Web UI without needing a browser. This even includes verifying confirmation email callbacks. I've constructed web apps in other environments (e.g. LAMP, ASP) and never had this level of automated testing. Its surely not impossible in other development environments, but somehow it never happened. I've been thinking about why in the Pharo/Seaside environment this seemed so natural and I've come up with these reasons: 1. It required no extra infrastructure or products to set up the test environment. Seaside's server, the WebClient clients, Soup, and the TFLogin test app are all present in the Pharo image. 2. No shell scripts or Perl or Python code was necessary. 3. The tests cases are integrated into the development environment, and are not in another tool or language. Regards, TF

[Pharo-project] additional font size?
by Alexandre Bergel Jan. 10, 2011

Jan. 10, 2011

Hi! Apparently, the 1.2 image contains only the size 7, 9 and 12 for Bitmap DejaVu Sans. Can we get additional font sizes? Are there a vectorial font police supported in Pharo? I would like to be able to give any arbitrary font size. Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

[Pharo-project] How to display an image from an external PNG/JPG file in a Morph?
by Dimitry Golubovsky Jan. 10, 2011

Jan. 10, 2011

Hi, Thanks Alain, this worked for me. Alain Plantec wrote: > (ImageReadWriter formFromFileNamed: 'pharoLogo.jpg') asMorph openInWorld > works also PS Before asking on the list I tried to google on the topic, nothing relevant returned. At least now googling for "pharo display png file" yields this mailing list thread in the first page among other not so relevant results: someone like me will find the answer faster. Thanks again. -- Dimitry Golubovsky Anywhere on the Web

[Pharo-project] Custom Parser class
by Igor Stasenko Jan. 10, 2011

Jan. 10, 2011

Hello, i stumbled upon weird thing. In my own class i wanted to define own custom parser class, by implementing MyClass class>>parserClass and it seems works only for parsing during source code highlighting, but completely does not taken into account when compiling methods of my class. Is this done by intent, so to specify custom parser, first i need to provide a custom compiler , which providing custom parser? And if not, this should be fixed. See http://code.google.com/p/pharo/issues/detail?id=3525 for details. -- Best regards, Igor Stasenko AKA sig.
