Jean-Baptiste Arnaud outlines his work and contributions to the Pharo community, focusing on static analysis for Python and the development of the Pharo ARM roadmap. He details the progress on Raspberry Pi tasks, including VM development and configuration, and notes the cessation of the CogDroid project for Android. Future tasks include improving GPIO support and reviving the Android VM while maintaining close alignment with Unix sources.

2. Who I am
• PhD in Language design and security
• Member of the Pharo community since 5 years
• Doing a post-doc in RMoD Team, working on static analysis on python
• Maintainer of the ARM for Pharo

3. Roadmap
• Raspberry Pi Status
• Android Status
• Small demo :-)

4. Raspberry Pi

5. Tasks done
• Stack Interpreter
• VM with FastBltBit (T. Rowledge, B. Avison)
• Complete Building process
• On http://files.pharo.org/
• FFI arm (Doug Mc Pherson), OSProcess
• A StackInterpreter with NativeBoost

6. Issues
• Raspberry Pi configuration
• Raspberry Pi Toolchains
• Raspberry Pi is not a desktop computer

7. Recommendations
• Do not upgrade your platform every day
• Develop on Unix and release on Raspberry pi
• Remote tests / Automatic tests

8. How to Extend The VM
• Fork the pharoVM github repository
• Subclass of StackCrossRaspbianFastBltConfig
• Go on Pharo Contribution:
• Copy the jobs:
• RaspberryPi-Cog-Git-Tracker, linked your pharoVM
fork
• RaspberryPi-Cross-Compilation-FastBltBit, here call
your configuration subclass

9. Tasks to be done
• Add a GPIO support (Wiring Pi lib via FFI) in
progress
• Jenkins tests / Specific automated Tests
• Pharo for Embedded
• VCPU Arm (Ask Igor) ==> NativeBoost ARM
• JitCompiler for ARM (Ask Tim)

11. Android

12. Android Status
!
• CogDroid project stopped since ~ 2 years
• Based on a fork of unix sources
• Not maintained anymore

13. • Goals
Android Status
• Revive the Stack VM
Android
• Keep the source
closest possible to the
Unix Sources

14. Tasks done
• Tamed the Native Android process
• Redirected the VM Debugging methods to
logcat
• Be able to load external libraries from VM
• Managed Display plugin as external library
• Run a Pharo40 image

15. Jobs to be done
• Manage Events
• Merge with PharoVM Repository master
• Configuration generator
• Jenkins Process
• Android primitives
• Job to package images into Pharo applications
