Roassal2 orthogonal lines, attach points and self-lines.
by Peter UhnÃ¡k Aug. 17, 2014

Aug. 17, 2014

Hi, is there any support for orthogonal lines in Roassal2? I've seen something similar (ROOrthoVerticalLineShape), however nothing of that sort in Roassal2. I would imagine it to behave similarly to RTBezierLine - having controllingElements to specify the corners. (While ROOrtholines did it automatically I was looking for something more manual, so it can go in both directions - thus the controllingElements). Second thing I wasn't able to figure out is whether it is possible to create line from element to itself. All *AttachPoint classes aren't really able to cope with that. The best result I got was from Vertical/Horizontal AttachPoints (combined with BezierLine), however I would like to be able to specify which side it would start on and end on. Ideally not just middle of sides, but arbitrary part of the shape (I imagine that might be hard for non-rectangular shapes). Thanks, Peter

Hi, I would like to compile a FFI program but the compiling implies compile flags like in the following : gcc -Wall helloworld.c -o helloworld $(pkg-config --cflags --libs gstreamer-1.0) How do I do this with FFI ? Annick

Hi, The Bootstrap wrapping project for Seaside now has also support for the Jasni Bootstrap extension (see http://jasny.github.io/bootstrap) Seaside Examples can be found on the following URL's http://pharo.pharocloud.com/bootstrap/browser/Jasny%20-%20Button%20Label http://pharo.pharocloud.com/bootstrap/browser/Jasny%20-%20Input%20Mask http://pharo.pharocloud.com/bootstrap/browser/Jasny%20-%20Navmenu Hope this is useful.

Re: [Pharo-users] [Moose-dev] Re: Tree/Outliners of playgrounds, markdown inside comments and some quick medium size dreams for Pharo/Smalltalk
by Tudor Girba Aug. 17, 2014

Aug. 17, 2014

Hi, You probably need this: explorer transmit to: #tree; andShow: [:a | a tree display: headers; *children: [:eachNode | eachNode theMessageYouUseToGoToTheChildrenOfANode ]*]. A tree is a recursive structure, and to describe it you need: - a way to construct the root elements. This is the result of applying display: to the input object. So, display: either takes a collection or a block that will return a collection when executed. - a way to define the children for each node. This is the result of applying children: You should also take a look at the examples from: GLMBasicExamples open Does this help now?

How do I get ZnClient to follow redirects from Google App Scripts
by Andy Burnett Aug. 16, 2014

Aug. 16, 2014

Hello, Google Apps Scripts allows me to create a webapp function that returns json. For security reasons the url to call the function returns a redirection. For example Curl https://script.google.com/macros/s/AKfycbyjVyXa9cYqYZg6kfSdiT8l6S0Q3LEzn6Fv… Returns an html page with the redirection information, whereas curl -L https://script.google.com/macros/s/AKfycbyjVyXa9cYqYZg6kfSdiT8l6S0Q3LEzn6Fv… Returns the json value (currently 13) I tried to use ZnClient to do the same thing, and I thought that ZnClient automatically followed redirections, but when I inspect the value it seems to actually return a larger html page, rather than the json. My Pharo code is: (ZnClient new) get: ' https://script.google.com/macros/s/AKfycbyjVyXa9cYqYZg6kfSdiT8l6S0Q3LEzn6Fv… '. Do I have to set any other options? Please Note: this is my first experiment with Google App Scripts, so it is very likely that the problem is with my script, rather than Pharo. However, the script does seem to be returning the correct value in the browser, so it might be some interaction between the two. Cheers Andy á§

[ANN] Live Robot Programming
by Johan Fabry Aug. 16, 2014

Aug. 16, 2014

Hi all, itâs with great joy that I can announce the project that my PhD student Miguel and I have been working on recently: Live Robot Programming, or LRP for short. LRP is a live programming language designed for the creation of the behavior layer of robots. It is fundamentally a nested state machine language built with robotics applications in mind, but it is not bound to a specific robot middleware, API or OS. Have a look at one minute of LRP programming to get an idea of what it is like: http://youtu.be/4Ma8ZapBUqA Live programming is fun, and live robot programming even more so, as it brings all the advantages of live programming to programming a robot. You get direct manipulation of a running robot, and thatâs just cool beyond words. As an example of LRP on a robot, this guy was programmed in LRP: http://youtu.be/4Ma8ZapBUqA Note that you can use LRP âjustâ for live programming nested state machines as well. More information on LRP is available on its website: http://pleiad.cl/LRP where you can also find download instructions. LRP is implemented in Pharo, and uses Roassal2 for the visualization of its state machines. We currently can steer the Lego Mindstorms EV3 and ROS robots, thanks to a small layer on top of the cool Pharo support that Jannik, Luc, Santiago and Noury are implementing at Douai. I am going to look into support for the Parrot AR.Drone 2.0esug in a few weeks. Miguel will be at ESUG next week (I cannot make it), and has a talk at the IWST workshop about LRP, in the morning session. I am sure that he will also be happy to give demos of LRP if you ask him to (but sadly without a robot). All feedback is welcome, and â¦ have fun! ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

Accelerate UI
by Norbert Hartl Aug. 15, 2014

Aug. 15, 2014

I'm working on a raspberry pi via remote window. As the StackVM is rather slow on the device something things make it hard to work there. But I need to work there because I'm doing FFI stuff. Which are the options to turn off features that might speed up UI responsiveness? I switched off syntax highlighting and code completion already. Anything I can tune Nautilus? thanks, Norbert
