Re: [Pharo-users] Generating flow chart / state diagram from Moose

by Tudor Girba

Hi Norbert, You should indeed look at Roassal. Could you give us an example of the data you have? Perhaps we can get you started with an example.

As far as I understand it is suited for larger distributions of rather homogenous shapes. I know you can choose different shapes for different views.

I'm implementing an communication stack [1] where the central behavior is a huge state machine / flow chart description [2] (the state machine / flow chart is described on page 30 to 60). This is a task that is hard to do right without any guidance. My idea is to figure out a way to annotate the sources in a way to get the right points in control flow from code. From this I like to create a diagram that is semantically equivalent to the description in the spec. I'll need therefor things to create state machine / flow charts, meaning shapes, directed arrows, branches etc.. Well, my dream would be to inject a real data packet into the communication layer and get a diagram where the path taken is highlighted :) > > The best approach I have til now is to generate a graphviz dot file for the diagrams but using anything from Moose would indeed be nicer. > > Norbert > > [1] http://en.wikipedia.org/wiki/Transaction_Capabilities_Application_Part > [2] http://www.itu.int/rec/dologin_pub.asp?lang=e&id=T-REC-Q.774-199706-I!!PDF-… -- www.tudorgirba.com "Problem solving efficiency grows with the abstractness level of problem understanding."

Perhaps you could give Moose a try :). For a quick experiment: 1. Download https://ci.inria.fr/moose/job/moose-latest-dev-4.8/lastSuccessfulBuild/arti… 2. Execute ((MoosePharoImporterTask new addClasses: {Morph}; run) allModelClasses entityNamed: #'Smalltalk::Morph') openInMoose 3.

Re: [Pharo-users] Need help with dynamically finding packages/categories on pharo

Hi, Perhaps you could also take a look at Moose and the included engines such as Glamour and Roassal. You can download an image from here: https://ci.inria.fr/moose/job/moose-latest-dev-4.8/lastSuccessfulBuild/arti… Cheers, Doru On Apr 8, 2013, at 12:48 AM, ashwinshankar77 <ashwinshankar77(a)gmail.com> wrote: > We are using Morphic for visualization and MCWorkingCopy and few other > classes to get > package related information.

We are using Morphic for visualization and MCWorkingCopy and few other classes to get package related information. We just started off,so we have not completely figured out what things to use. Sure,I'll let the others know about using Pharo2. -- View this message in context: http://forum.world.st/Need-help-with-dynamically-finding-packages-categorie… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

That's great! I think providing packages for LTS versions of ubuntu would be good.

by Damien Cassou

Dear Pharo and Ubuntu users, Nicolas Petton and I are proud to announce Ubuntu packages for the Pharo VM. Installing the pharo vm is now just a matter of: sudo add-apt-repository ppa:cassou/pharo sudo apt-get update sudo apt-get install pharo-vm With this package, you get: - the latest pharo vm as a 'pharo' binary in the PATH - all plugins and libraries (native boost, freetype, ssl, ...) - file association so you can just double-click on pharo images - pharo icons visible everywhere (on image files, on ALT+TAB...) - PharoV10.sources and PharoV20.sources Please fill bug reports on https://pharo.fogbugz.com. This package is currently only available for Ubuntu 12.10 Quantal. Fill a bug report if you want me to package it for another version of Ubuntu. -- Damien Cassou http://damiencassou.seasidehosting.st "Success is the ability to go from one failure to another without losing enthusiasm."
