Ideas for a binary format for an image acting as an extension of the Pharo image
by Dimitris Chloupis Nov. 9, 2016

Nov. 9, 2016

So now that CPPBridge at least basic are sort out I have to figure out a binary file format The idea here is to implement an image format which will be part of the memory of the Pharo process but will live outside the memory of the Pharo VM. Lets call this CPPMemory will be stored to an image file, lets call it CPPImage, like we do with the Pharo image and will store a shared state among all other processes (Pharo or not) that connect to this shared memory (CPPMemory) via accessing the file (CPPImage). So basically it will act as an extension to the Pharo image. In the image file , objects will be stored obviously not in a byte-code format but definitely in a byte format that will basically store the data of this object using very basic primitives like character , integers and of course bytes. Obviously each object will have to have an id as a header and also its size in bytes and the size of each of its instance variables. There will be also a global headers for the entire file with the list of the objects included and probably a references to other CPP images that they will be able to interconnect with each other like lego blocks. Thats my vague idea, but I am open to suggestions and even links to articles and documentation about what a binary format must have to be considered well architectured. Obviously I dont expect perfection because this is my first binary file format but at least I am looking for advise for avoiding common pitfalls.

That's great to hear. Let me know if the latest commits do work for you (they should work for 5.0.2).

UFFI can not generate Structure accessor of type char[100]
by Dimitris Chloupis Nov. 9, 2016

Nov. 9, 2016

I have FFIExternalStructure which has at class side fieldsDesc ^#( char data[100]; int count; ) if I try to do EphCPPTestStructure rebuildFieldAccessors . in order to generate the accessors for the members of the struct it complains with an error that it does not recognise the type of " [ " Does that mean that char arrays are other arrays are not supported as struct members or will I have to do this manually ?

[ANN] Introspect web content (Soup with some GT extensions)
by Torsten Bergmann Nov. 8, 2016

Nov. 8, 2016

Hi, I added a few GT inspector extensions to Soup and cleaned up a little bit. Released as a new version 1.8 of Soup - you will find easily in Catalog for Pharo 5 or by opening Spotter and entering "Soup" to load. As the attached screenshots shows you now have a nice way to introspect the structure of a web page as a tree in the inspector or see the attributes of tags/nodes in a table. Thx T.

Matteo your emails format looks quite strange...

I would say yes because as you I find this suboptimal. Now may be it was created like that because of incompatibilities between uses of PluggableIconListMorph (RIP) and FT. Nothing is simple when you have legacy and different interaction protocol > > Could the "MorphicImageFastTableAdaptor" use directly a "FTTableMorph" > object, instead of creating "pluggable" adapter? Could you give a try and let us know. I' super hyper fuulllllll (tomorrow 6 hours teaching). > > cheers, > Matteo

[ann] petitparser2
by Tudor Girba Nov. 8, 2016

Nov. 8, 2016

Hi, I am happy to announce the availability of PetitParser2, a wonderful redesign of the original PetitParser developed by Jan KurÅ¡. https://github.com/kursjan/petitparser2 Highlights: - it introduces the compiler facility that speeds up parsers by a factor of ~2-5x - it introduces the possibility of parsing streams without having them in memory - it comes with a new structure internally that makes it more flexible - it introduces asPParser (not a typo) to be able to have the new version working in parallel with the classic asParser The version is already present in the latest Moose 6.1 in parallel with PetitParser. Also, several of the parsers that are shipping with PetitParser were already copied to PetitParser2 as well. You can find more details here: http://www.humane-assessment.com/blog/introducing-petitparser2/ Some more documentation will follow. I think Jan did a wonderful job and the result is quite exciting. Please take a look and let us know what you think. Cheers, Doru -- www.tudorgirba.com www.feenk.com "What we can governs what we wish."

ZÃ¼rich Smalltalk Meetup Reminder
by jtuchel＠objektfabrik.de Nov. 8, 2016

Hi there, in case you forgot about it: The ZÃ¼rich Smalltalkers will meet tonight at 7pm for another meetup. There will be at least 2 presentations: * Reza will show Web Pontoon * Michal will show hs current work on a new Pharo-Gemstone/S-bridge * who knows, maybe you feel like demoing tonight? This time, we meet at a nice conference room first and go for drinks and dinner later. Here is where you can get in touch with Smalltalkers of all flavors, colors, shapes, sizes, ages and genders: Alpha Sprachwelt AG <http://alphasprachwelt.ch/kontakt.html> Stadelhoferstrasse 10 â Room 23 â 8001 ZÃ¼rich See the location on a map <https://wego.here.com/directions/publicTransport/Alpha-Sprachstudio,-Stadel…> So feel free to come and chat a little or discuss your current work. Joachim (I won't be able to attend, unfortunately. The best thing I could do today would be to share a few virusses with you and help you get a few days off. But I am eager to hear if this new format in a meeting room works well. Have fun!!!)

Linking issues to versions (bug analysis) in pharo
by Yuriy Tymchuk Nov. 8, 2016

Nov. 8, 2016

Hi, has anybody done anything with bug analysis in Pharo? I know that the most common approach is to see in which version an issue was closed and what code was changed and when was that code introduced and as the result you have lifespans of bugs. Other suggestions are also welcome :) Uko
