Roassal Sunburst examples not working

by Arturo Zambrano

Hi, I just installed Roassal in a 2.0 Pharo image All the examples of Sunburst raise a MNU but in a red background window (screenshot attached). It seems that something prevents the debugger to open. Any hint about this? Maybe there is a missing dependency of Roassal sunburst thanks art

Re: [Pharo-users] NativeBoost callbacks from different threads?

by ClÃ©ment Bera

Hello, This is still true in Pharo 3 AFAIK. With NativeBoost you need to have the call back in the same thread as the VM. If you want multithreaded callback you can do it through the FFI VM plugin and the Cog Multi threaded VM (you can find the CogMT VM prebuilt for Pharo here: https://ci.inria.fr/pharo/view/VM/job/CogMTVM/ ). However it depends what you want to do with your call backs. This VM looks stable but very few people use it so it may not be as stable as it looks like. So if you plan to use it for real (like production app) do some experiments before to see if your use cases work fine. 2014-02-02 Joachim Geidel <joachim.geidel(a)onlinehome.de>: > In 2012, Igor Stasenko wrote: "the limitation is multithreading. callback > should be called in same > thread as VM." > http://forum.world.st/NativeBoost-callbacks-status-td4656362.html#a4656371 > > Is this still true in Pharo 3.0?

This is loadable as group 'REST' from ConfigurationOfZincHTTPComponents. You create subclasses under ZnRestCall, ZnAutoMatchedRestCall or ZnJSONRestCall and implement #get, #put, #post and/or #delete methods for each resource endpoint. The framework offers dispatching (routing) and some conversions and conveniences, but you can basically do what you want. Check out the unit tests. Sven

Re: [Pharo-users] Unicode

by Sven Van Caekenberghe

Bob, If you enable TrueType in the System Settings and then select Arial Unicode MS as font you get a very wide set. This works for me on Mac OS X. I guess you could try to find, install and load any font with a large Unicode coverage. What we lack today is a mechanism for transparently and automatically substituting unavailable glyphs from one font with another one where they are available. That would be nice.

Unicode

by Bob Williams

It would seem that the infrastructure for Unicode is in place, but there seems no apparent way to load Unicode fonts. The code example for loading TrueType does not work. Can some one point me to documentation on how to load Unicode? Thanks. Bob williams

Re: [Pharo-users] Hyperion (vector graphics editor and GUI designer using Athens)

by Bob Williams

Kilon I can probably help you as it was in a Smalltalk application that I developed in the early 1990s, ObjectiveFM, for my doctoral dissertation and later was a commercial product. The method is below and it is for a cubic Bezier spline. I am considering add a GIS package to Pharo and would like to have assistance. I would also note that you should look at the series of books called Graphics Gems (5 books) that are a great resource.
