Re: [Pharo-users] Kivy

by Glenn CavarlÃ©

Kivy embed a Python interpreter in a native mobile app. All is developed in Python in association with their own declarative language : the kivy language. To do the same thing with Smalltalk, i think you have CogDroid or PharoDroid that embed a smalltalk vm in a native mobile app. When Bloc Widgets will be available, it should be easy to provide a "wonderful" mobile-specific widget layer. You can already do things like that with Bloc : <http://forum.world.st/file/n4835762/BwtMobile.png> (I'm using it as a simulator for mobile apps developed in Pharo) In another way, I'm working on a mobile development environment based on Pharo (part of my phd thesis). The goal is to use Pharo such as a modeling, development and validation environment in order to finally generate fully native mobile applications for several platforms. So, i hope that Pharo will become mobile soon ! ;) Regards, Glenn. ----- Glenn CavarlÃ© -- View this message in context: http://forum.world.st/Kivy-tp4835739p4835762.html Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

All. Without forgetting multiplateform. I mean when you have such a framework, people get attracted, although Kivy was likely developed the other way: developed for Python because Python is well know and widely used. I am curious to know how Kivy was developed in the first place: a small community effort, a corporation in house developed tool, funding...

LANG value on my system is probably typical and is 'fr_FR.UTF-8'; how would that match Phratch language settings ? Regards, Thierry

Hi Thierry, It is a choice :) Scratch uses the scratch plugin to do that. In phratch, I removed the scratch plugin, to be sure to be compatible with platforms where it is not available. Maybe, we can reintroduce it using OSProcess or NativeBoost. If you have a code snippet, I can use it.

I do not mean they should be included, just a larger font size.
