I see interesting new fields Preload and Postload in Fogbugz. I could guess... but it would be useful if someone could describe their usage? cheers -ben

Ephestos 0.1 released
by kilon alios Sept. 21, 2014

Sept. 21, 2014

This is 0.1 the first stable release of Ephestos. This release contains the following -a socket client bridge for sending and receiving messages from Blender which acts as a socket server a sendMessage: message to send python command as string to Blender to be executed a python parser that allows the pharo syntax to be used to parse to a python command for simple things like calling instance and class method and assigning class and instance variables a getValue: message for reading python values from variables support for triggering the pharo debugger on python error support for sending multiple lines of python code in a single message, for defining python classes and much more. A video demonstration can be found here only for the new features: https://www.youtube.com/watch?v=XPGDQc5LUvE&feature=youtu.be Documentation is here , its outdated because it does not contain the new features but will update in a few days --> https://www.gitbook.io/book/kilon/ephestos With release 0.1 the core features of Ephestos have been finalised. It now can be used for full controlling Blender. The next step is to refine getting values from Blender so they are automagically converted from strings to Pharo data types. I also will start working on a customised GUI and creating an API for it, the goal is to build GUIs that heavily rely on images and custom skins with ease.

[ANN] ExternalTools for *nix - edit w/ $EDITOR and open pictures
by phil＠highoctane.be Sept. 21, 2014

Sept. 21, 2014

I had enough to switch between windows to work on external files. So, here is ExternalTools It adds some commands to the File Browser, allowing one to edit in the $EDITOR (for me this is gvim) and another thing for opening the file externally through xdg-open (which kind of opens about anything). Basically, one can extend this to whatever is needed. The only thing is that FileServices initialize needs to be called when a new service is added if you create your own. This is Unix only and requires OSProcess to be loaded (use the ConfigurationBrowser). Gofer it url: 'http://www.smalltalkhub.com/mc/philippeback/HOExtras/main'; package: 'HighOctane-Tools'; load. Screenshot in attach. Doc here: https://gist.github.com/philippeback/8e8f8c6685bebf47f53f Phil

Parsing Pharo syntax to C/C++

Sept. 21, 2014

Is there a way to convert code from pharo to c or c++ ? Does pettit parser or other parsers offer such support ?

proposed ThreadSafeTranscript>>ensureOpen
by Ben Coman Sept. 21, 2014

Sept. 21, 2014

I often use Transcript output in my adhoc issue-isolation scripts, and it would be nice to ensure a Transcript is open at the start of a script, but I can't current see an option besides "Transcript open" which would open too many Transcripts over time. I'd like to add to Pharo something like... ThreadSafeTranscript >> ensureOpen "It seems that closed Transcript windows hang around and confuse the #detect. Garbage collecting is easier than trying to reopen a closed window. " Smalltalk garbageCollect. ^ PluggableTextMorph allInstances detect: [ :ptm | ptm model = self ] ifNone: [ self open ] The hard coding of PluggableTextMorph matches that in ThreadSafeTranscript >> openLabel:. Thoughts anyone? cheers -ben

Live Visual Coding environment inspired from Smalltalk and iPython
by kilon alios Sept. 21, 2014

Sept. 21, 2014

its called Larch , its for python but it may be inspiration for anyone want to implement something similar for Pharo. Its also an area that interests me too. http://www.larchenvironment.com/ in interface its similar to iPython notebook but with features we are used to have in Pharo.

Visualising Network Latency
by Leonel Merino Sept. 20, 2014

Sept. 20, 2014

Hi All, I have been working on a visualisation of latency on a network. I found an interesting dataset with latency information of 140 cities around the world. In the visualisation I show different metrics regarding latency such as from each city which other has the best/worst latency; cities that geographically are close but have high latency; far cities that have low latency; and average latency for each city. When visualising the worst latency for each city I found that, for this network (at least), Valencia and in a minor extent Nairobi represent the worst endpoint for connections (in terms of latency). Also in the visualisation of far cities with low latency, Newmarket in Canada and Toledo in Spain concentrate the best endpoint for connections coming from Europe and North-America respectively. Here a couple of screenshots: Here there is a screencast: http://www.youtube.com/watch?v=gDQnE-5yeWI If you want to load the code: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Gofer new smalltalkhubUser: 'merino' project: 'NetworkLatency'; package: 'ConfigurationOfNetworkLatency'; load.

Issue Tracker Cleanup - UITheme hierarchy
by Ben Coman Sept. 20, 2014

Sept. 20, 2014

There are two tickets that follow on from Pharo 3 beta bug fixing I was involved with, but I don't really know the UITheme architecture well enough to follow up further. Others seem to have got quite involved with themes and I wonder if someone might kindly be interested in following these up. Otherwise I guess I'll just close them as abandoned. https://pharo.fogbugz.com/default.asp?13118 Clean up the mess in UITheme hierarchy https://pharo.fogbugz.com/default.asp?13121 Cleanup Colors & FillStyles for UITheme & PluggableTextMorphWithLimits cheers -ben

Pragmas - compile time versus run time
by Ben Coman Sept. 20, 2014

Sept. 20, 2014

In consideration of Issue 11880, I wanted to better understand the concept of pragmas and how they are used in Pharo. "Pragmas" seem to be used in other languages to provide "compile time" directives, but Pharo seems search for pragmas at runtime, for example to do things like build menus. Mostly I'd consider menus fairly static (with any dynamism statically defined). In Issue 11880 adding a few caches brings menu generation from 80ms down to 5ms - but then there is the complexity of resetting them when the code that defines them changes. So I wonder... can/do pragmas cause actions at compile time, like setting a class variable to nil when a method is compiled? That seems a good way to reset a cache whose builder uses that method, but maybe there are problems I don't see? https://pharo.fogbugz.com/default.asp?11880 cheers -ben

The Dilemma: Building a Futuristic GUI for Ephestos
by kilon alios Sept. 20, 2014

Sept. 20, 2014

So far Ephestos has gone quite well and I am satisfied with my progress so far. I think its time to start thinking about a GUI for it. I was always very interested in creating futuristic GUIs like this http://vimeo.com/68113915 At first I thought about a project "Hyperion" to explore the idea of creating a vector editor in pharo, it was a fun experiment to see also the potential of Athens. However the more I think about the more unnecessary seems to me the use of SVG graphics. Back then I did not have integration with Blender so my idea now is to drop Hyperion and instead make the GUI inside Blender and export it as a set of animatable bitmaps. My dilemma is what graphic library to use : a) Morphic b) Athens or c)Roassal What I need is the following: 1) Ability to render small bitmaps fast and do animation , big bitmaps will be mostly static used for backgrounds 2) Basic interaction ability , mouse left and right click , mouse drag , mouse click press and release events. Of course keyboard events too 3) The ability to scale up and down images with minimum distortion 4) The ability to render text smoothly and scale it up and down 5) Transparency also plays a big role in layering those images I think so far that Roassal is the best candidate because it also integrates well with Morphic and Athens. Also I may still need some vector graphics for example charts or dynamic graphics that will depend on user input that would not be suitable to do strictly with SVG so the morphic option is getting weaker and weaker. I wanted a second opinion though since you are much more experienced than me. I may also create an API for creating such GUIs with Blender for Pharo. Another thing I am wondering is how to download all these images to Pharo , what you guys use to do download big data to Pharo , maybe Fuel ?
