Yes, I would say so... I have to admit that I am a fan of the general "beyond ASCII" idea of which one sees a tiny gimpse of a shadow in Squeak... but the way it was done in Squeak was never really good enough and people did not use it at all. (Partly because both Morphic and it's text model as well as the UI never was any good...). E.g. the first thing you want in comments is embedding Figures (e.g. of Datastructures)... or even life working examples. Is there anything that Squeak Rich Text (of the kind that is serializable as a method style) can do that Markdown can not? http://en.wikipedia.org/wiki/Markdown -- Marcus Denker -- http://marcusdenker.de

Re: [Pharo-project] About NonInteractiveUIManager>>#onSnapshot: and related

by Camillo Bruni

indeed the non-interactive one keeps the previous version alive in the instvar... I just copied the existing implementation (without much motivation). Bit for simplicity's sake we should simply instantiate every time the proper ui manager, that would simplify these ugly methods quite a bit. cami On 2012-03-21, at 04:12, Igor Stasenko wrote: > the logic there was to set a non-interactive ui manager > for headless sessions only , and then restore back a previous one > (whatever it is), once session is changed back to headfull. > > if its uiManager is nil, it should reset the default manager, > if i remember correctly, then UImanager itself will take care > instantiating default one. > > On 21 March 2012 04:35, Guillermo Polito <guillermopolito(a)gmail.com> wrote: >> Hi, >> >> I was doing some hacking, and playing with NonInteractiveUIManager.

[Pharo-project] Concrete Type Inference

by Francisco Garau

Hi - we are trying to port to Pharo some work I've done on Concrete Type Inference back in 2001. I've got a Squeak 2.8 image which is working, but having some minor problems with the pluggins. Is there a public repository where old Squeak distributions are stored? Thanks, Francisco

[Pharo-project] R: R: [Moose-dev] numerical method in smalltalk

by Lorenzo Schiavina

Hi Serge, if you can understand Italian, you can see a presentation at: http://www.edor.it/index.php?option=com_content&view=article&id=30&Itemid=65 This application has been developed in VSE, but a student of mine has already done (a partial) porting in Squeak; he already told me that he wanted to send it to Squeak community so, if you want, I can send it to you. At present the code has no special license and I will be pleased to integrate it into a bigger package with any kind of license. My application has a specific fuzzyfication/defuzzyfication method but, if you consider it useful, I can extend it to some other theoretical approach. As a matter of fact, my application (not my student's) is an environment for creating expert systems that have been used in many different fields (medical, forecasting, sport, environment control).
