Call for action for Roassal
by Alexandre Bergel March 28, 2016

March 28, 2016

Dear community, As you may have seen, Roassal has entered a stabilization phase. The book AgileVisualization.com will soon be released. After its release, Roassal will go over a new development phase. In order to prepare it, I am asking this question: What are the 3 aspects you would like to see improved in Roassal? You can answer publicly or by sending private messages. Kind regards, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.

Maybe also OGDF (http://ogdf.net/doku.php) could be used if you are ok with GPLâ¦ they have their own graph format so there could be some interaction. Peter

Custom type inference and RoelTyper
by Peter Uhnak March 14, 2016

March 14, 2016

Hi, Moose/FAMIX uses RoelTyper for type inference, how this does not seem to be maintained (last version 2013), and for my purposes is lacking. So do we have something more advanced, even at the expense of speed? Other alternative would be to either extend RoelTyper or write something custom that would be ran alongside RoelTyper. Examples of such extensions would be extracting the type from meta-annotations and the actual argument names. (e.g. if an argument is named aString, I can safely assume that it will be String). Thanks, Peter

Who is using Pharo Launcher and for what
by Damien Cassou March 4, 2016

March 4, 2016

For my CV, I need to know who is using the stuff I'm doing. If you use the Pharo Launcher, could you please tell me in which context (e.g., which company, open-source project) and what you use it for (e.g., download from CI, standard Pharo)? I don't need long paragraphs, just give me the keywords please. Thanks -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm." --Winston Churchill

A new idea for a project: WarpSpeed (a C inliner)
by Dimitris Chloupis March 2, 2016

March 2, 2016

So now that AsmJit is gone , I had a new idea for a project and I wanted your opinion on this if you think it will be useful for the community, I call it WarpSpeed. I was thinking it would still be cool to have some kind of library that will help us boost the speed of pharo . So I was thinking about a C inliner which is far easier than an Assembly inliner (see AsmJIT) I also found TinyC http://bellard.org/tcc/ which is as you guessed a tiny c compiler 100kbs in size which i can include with a pharo image to allow me to dynamically compile inlined C code inside the pharo image so even pharo users without a C compiler installed can benefit from it . That means that if something does not perform as fast as you want you could mix C code with pharo code , I am thinking passing the C source code as a string or even having the C code in a separate file, and then dynamically call the TinyC compiler, compile it to shared library and load if via UFFI back to pharo. TinyC is very fast so compilation of the code should be as fast if not faster than compiling pharo code. Looks easy enough to do for a small project by me with the condition there are people really interested into something like this. TinyC is licensed as LGPL but I can make it fall back to other compilers as well if ones want to close the source. How it sounds as an idea ?
