Maintainer of FFI-Package
by Nicolai Hess 12 Sep '15

12 Sep '15

Who is the maintainer of the FFI-Package for Squeak and/or Pharo ? I especially interested in the FFI-Unix examples and the state on working FFI on linux for current squeak release (AFAIK it does not work with "squeak all in one" 4.5) regards Nicolai

ByteArray accessors for 64-bit manipulation
by Chris Cunningham 09 Sep '15

09 Sep '15

Hi. I've committed a change to the inbox with changes to allow getting/putting 64bit values to ByteArrays (similar to 32 and 16 bit accessors). Could this be added to trunk? Also, first time I used the selective commit function - very nice! the changes I didn't want committed didn't, in fact, get commited. Just the desirable bits! -cbc

Regex
by Levente Uzonyi 08 Sep '15

08 Sep '15

Hi All, I've ported Pharo's version of VB-Regex to Squeak, and uploaded it to the Inbox. Unfortunately the file was probably too large for the server to send an email about it. Just evaluate the following snippet to install it: Installer squeakInbox addPackage: 'Regex-Core-ul.37.mcz'; addPackage: 'Regex-Tests-Core-ul.1.mcz'; install. Compared to the PCRE-based Regex package, which can be loaded from SqueakMap, this library is significantly slower and has less features, but it's written in Smalltalk. Levente

Updating SAR builder tool
by tim Rowledge 05 Sep '15

05 Sep '15

I’m looking into using .sar files as a way of delivering Scratch device driver stuff for the Raspberry Pi. It’s been more than a few years since I last had to think about SARs (actually from my emails it looks like 2004 was the last time!) so a bit of trawling through the swiki was in order. I’ve updated a couple of pages relating to SARs to (hopefully) make them a touch more useful these days, and just tried loading the very old SARBuilder package from SqueakMap. Don’t forget that you have to hit the menu in the top-left list of the Squeakmap tool in order to turn off the filtering that makes it invisible since it isn’t thoroughly up to date. It installs ok after using Preferences to allow underscores as assignment; so there is one update needed in the code. It even appears to run its example (SARChangeSetDumper class>>example1) ok. However, it clearly needs some updates to make it a better citizen; for example it completely overwrites the ChangeSorter>>changeSetMenu:shifted: method. I don’t have any time to clean it up right now since I have a release to assemble for about 7 million Pi’s. It seems like it might be a relatively simple fixup to make an old tool usable once more. tim -- tim Rowledge; tim(a)rowledge.org; http://www.rowledge.org/tim Strange OpCodes: RLB: Ruin Logic Board

Can you explain what you want to achieve and how I can make this more convenient? Best regards -Tobias

[Bug] Cannot use non-english characters even after loading a proper font
by Mateusz Grotek 01 Sep '15

01 Sep '15

Hi, First of all thank you for the new version of Squeak. It's really great. Special thanks for Tobias and Marcel for the font import tool! It works perfectly. Nevertheless I have noticed that there is a regression in Squeak 4.6/5.0 in the font handling. It's not possible anymore to use non-english characters even after loading a font that contains them (I've changed the code font and tried to use the characters in a workspace). Can anyone verify?

PDX -- a quick and dirty roundup
by Chris Cunnington 31 Aug '15

31 Aug '15

News (from my perspective): - Dolphin ST is still alive and available (link below) - Ken Dickey has a nifty morph control gui kit called Emergence on Cuis that looks Maui-esque (link below) - Camp Smalltalk Vanisle is intended to go in October even though they have not announced yet - No Cincom people were here. - Dale and Paul worked on Metacello. This: (Installer repository: ' http://www.smalltalkhub.com/mc/Seaside/MetacelloConfigurations/main') install: 'ConfigurationOfSeaside3'. ((Smalltalk at: #ConfigurationOfSeaside3) project version: #stable) load: #('Development' 'Welcome' 'RSS-Examples' 'Seaside-Email' 'Seaside-Examples' 'Seaside-Tools-Web' 'WebClient') will fail in Squeak for the time being until Metacello adds some kind of recognition parameters for Squeak 5.0. It will choke by asking for OmniBrowser. - Paul is trying to connect to LMDB via BerkeleyDB plugin which he has code for on his Github (links below) - There are pictures below of the Sat. evening dinner (link below) - Chris Thorgrimsson is about to release to the VW Store a package called PCAPNG which slices and dices Wireshark data down to the header level and lets you write your own filters. Alexander Bergel is expected to port it to Pharo. I made noises saying I might do bring it to Squeak but likely need to walk back from that position - I presented about Orange, a wiki I'm working on in Altitude inspired by TinyWiki that uses Xtreams PEG parsing - Sean presented about Gamour and gt toolkit - Martin presented about Mist and Fog his Smalltalk implementation that will never know C in any form - Seth of Instantiations presented about in-Workspace any-language code highlighting - I finally understood why Richie down in Buenos Aires sounded like he was speaking Mayan when I asked him about the kind of Smalltalk he was using when I saw him present at ESUG in 2011. If I recall correctly, he was using Visual Smalltalk Enterprise which is derived from Digitalk and was bought by Cincom, which made the image unavailable to anybody, but sold the rights to the VM to a company called Seagull, which sells the source code to anybody for $50,000. This made sense only to people who already had the image (i.e. Richie and LabWare) and looked like perversity to anybody else. You see why I didn't (and probably still don't) understand. - There is a company in Delaware called LabWare. They like Smalltalk. They have the above mentioned VM which a woman I met here (I think her name is Diane) has been upgrading by adding UTF8 and such. Their VM developer team was here at PDX (Boris, Andreas, Diane and Dave) and they are designing a VM from scratch. They tell me they will open source it. This was followed by the irritating news that they don't have any idea when they will even start a blog on the topic. It's sounds fascinating, so here's hoping they do. - James Foster presented a Gemstone to SQL database at ESUG that uses PetitParser and showed it here at PDX - The CSS and JavaScript libraries of the week mentioned at PDX included AngularJS, FlexBox, Google Materials, Angular Materials, Polymer, Ember and React - Some young programers are working on a new Smalltalk from an 80s paper by Wirfs-Brock called ModTalk (link below). It's modular and I don't think it has #become: - I learned more about #become: from a patient Martin by showing him code in VMMaker. The struggle is ongoing. That's the broad strokes for me. I imagine other people had different impressions.

What happened to Morph layering?
by Chris Muller 31 Aug '15

31 Aug '15

My Maui applications are suffering greatly by a change to Morphic during the 4.6/5.0 cycle which is causing morphs to be layered in the opposite order than they were in 4.5. The result is, I have morphs of a Proportional layout covering other Morphs which I need to interact with. The order within the 'submorphs' collection is the same, however, the layering appears to be the opposite. Any ideas?
