The Pharo Roadmap

M. Denker and S. Ducasse
http://www.pharo-project.org
Create an ecosystem
where business/innovation
       can bloom
Some Pharo’s success
stories
Seaside.st
Yesplan.be, netstyle.ch
Pier, DrGeo
Cmsbox.ch: Content Management
beta9.be: T3 Easy (Pharo server side)
Moose: www.moose-technology.org
pinesoft.uk.com: MBagger
Airflowing
Be able to invent our future
Done so far

1.3 is released (a lot, a lot, and a lot of improvements :)
1.4 alpha started
Jenkins server for everything
All VMs are automatically generated using Jenkins
Community Ongoing Work
Better widgets (A. Plantec, G. Chambers, B. van Ryseghem)

Better browsers (B. van Ryseghem, C. Bruni)

Key mapper (G. Polito)

Serializer (M. Dias, M. Martinez-Peck), Full Proxy (M. Martinez-Peck)

New source code model: Ring (V. Uquillas Gomez, A. Kellens, S. Ducasse)

New compiler (J. Ressia/M. Denker/JB Arnaud)

Zoomable interface (I. Stasenko)

Bootstrap (B. van Ryseghem/S. Ducasse)

Package distribution infrastructure (D. Henrichs)

Network (Zinc S. van Caekenberghe, Ocean N. Bouraqadi, L. Fabresse, J. Laval)

Remote Smalltalk (N. Papoulias and N. Bouraqadi)
Roadmap



Building the infrastructure for the next generation
Code Model Infrastructure
Able to query all the versions
What were the senders of this method in version
13168?
What is the diff between the senders in the past and
the one now?
Support for merging
Distributed source code
Code Model Infrastructure
Ring (V. Uquillaz Gomes/A. Kellens/S.Ducasse)
  Source code metamodel
  API compatible with Smalltalk objects
Adding layers on top of it
Porting all the tools to use it!
Reuse tools
Next Steps


Server for queries
New source code model
Athens Graphics
New Canvas
 Vector Graphics API
 Layered Architecture
   Backend Cairo /
   OpenGL OpenVG....
Next Steps

OpenGL bindings using NativeBoost
    done on Windows
Stabilize API
Adapt Morphic
Opal
We need a more flexible
and simpler compiler
Hooks for DSL support
Better API
New generation of tools
Next Steps

Decompiler (was the last missing bit) is nearly finished
Soon added in 1.4
Throw away the old compiler
Then improving the API
Fuel: Fast Serialization

 Done by M. Diaz, M. Martinez-Peck, (T. Bourgeois & S.
 Ducasse)
 Don’t use ImageSegment (removed in 1.4)
   Fuel is faster (!!)
   Much more flexible and easier to understand
Next Steps


Replace existing serializers
Migration path
Binary code loader
Scripting Syntax: Coral

 We want to write scripts in Pharo :)
 Headless
 REPL
 OS connexion (OSProcess for now)
 So we get Coral D. Pollet (and S. Ducasse)
[ Console puts: 'Before the command'. ]
[ "Let's define a command"
    | command |
    Console puts: 'duuuuhhh'.
    command := (CLICommandParser named: 'dostuff')
       aliases: #('dostuff.coral');
      description: 'This command does a lot of stuff. I
really mean a lot.'.
]
Distributions: towards a
certified catalog

 I want to go to Mars with just a DVD,
 and still be able to load the projects I want,
 and without internet, please!
Process
You use Metacello!
You publish in your repo!
When you want you can release code to a distribution
All the code then is recursively copied to the
distribution space
All the tests and quality rules are checked
People use your code but with a certain level of
confidence :)
Varia


 Making sure that we will be able to use announcements
 instead of SystemChangeNotifier
 Cleaning Morphic
 New package infrastructure
Package certification

Packages should be more self contained
Tests
LintRules
Meta data
Run and automatically certified
Native Boost

By Igor Stasenko (mac, linux and windows 32bits)
Generate machine code on the fly :)
Implement primitives
FFI
VM

Expand knowledge
Welcome newbies and idiots (like Stef)
Increase tests
Release VM builders from stupid tasks
Traceability/Branding
VM builds



Anybody is now able to build a vm!
VM Infrastructure


 VM validation after ANY changes
 Automatic recompilation
 Automatic test regressions
Nautilus


 Throw away StringHolder hierarchy (Yes Browser
 inherits from StringHolder)
 Browser based on a model
 Nautilus by B. van Ryseghem
Next Steps

Reimplement
 ChangeSorter
 MC UI
 Debugger
Mini Image


Pavel’s Mini image
4.2 mb for Seaside
Future?

Native boost
Google native client
Full bootstrap
More secure system
Pharo Consortium


How to sustain Pharo?
How to structure the community?
Should we always rely on people free time?
Consortium


You can participate to the consortium: Pay a fee


The consortium will pay a full-time engineer to support
Pharo tasks
When

Started discussions with INRIA two years ago
INRIA is ok to put money on the table (under
negotiation)
More than 25 companies are interested
Join!
Consortium FAQ


Pharo will stay free!
No negative impact: just a better Pharo
People and organization should be able to pay too:
a.k.a. Morale License
Pharo books

Pharo by example
 translated to french, merci!
 translated to spanish, gracias!
 japanese, german started
New books are coming

Pharo by Example Volume Two (deep into Pharo)
Pharo for the Entreprise
  If you want to contribute...
A glimpse at VM
Doing a Master with us :)
 Slim binaries (compressing AST as bytecodes)
 Virtual Filesystem
 Fuel-ing the code
 Source manager
 Peer to peer sources
 NativeBoost as a foundational engine
 Bootstrap next steps
Thanks

Pharo Roadmap

  • 1. The Pharo Roadmap M. Denker and S. Ducasse http://www.pharo-project.org
  • 2.
  • 3. Create an ecosystem where business/innovation can bloom
  • 4. Some Pharo’s success stories Seaside.st Yesplan.be, netstyle.ch Pier, DrGeo Cmsbox.ch: Content Management beta9.be: T3 Easy (Pharo server side) Moose: www.moose-technology.org pinesoft.uk.com: MBagger Airflowing
  • 5. Be able to invent our future
  • 6. Done so far 1.3 is released (a lot, a lot, and a lot of improvements :) 1.4 alpha started Jenkins server for everything All VMs are automatically generated using Jenkins
  • 7. Community Ongoing Work Better widgets (A. Plantec, G. Chambers, B. van Ryseghem) Better browsers (B. van Ryseghem, C. Bruni) Key mapper (G. Polito) Serializer (M. Dias, M. Martinez-Peck), Full Proxy (M. Martinez-Peck) New source code model: Ring (V. Uquillas Gomez, A. Kellens, S. Ducasse) New compiler (J. Ressia/M. Denker/JB Arnaud) Zoomable interface (I. Stasenko) Bootstrap (B. van Ryseghem/S. Ducasse) Package distribution infrastructure (D. Henrichs) Network (Zinc S. van Caekenberghe, Ocean N. Bouraqadi, L. Fabresse, J. Laval) Remote Smalltalk (N. Papoulias and N. Bouraqadi)
  • 8. Roadmap Building the infrastructure for the next generation
  • 9. Code Model Infrastructure Able to query all the versions What were the senders of this method in version 13168? What is the diff between the senders in the past and the one now? Support for merging Distributed source code
  • 10. Code Model Infrastructure Ring (V. Uquillaz Gomes/A. Kellens/S.Ducasse) Source code metamodel API compatible with Smalltalk objects Adding layers on top of it Porting all the tools to use it! Reuse tools
  • 11. Next Steps Server for queries New source code model
  • 12. Athens Graphics New Canvas Vector Graphics API Layered Architecture Backend Cairo / OpenGL OpenVG....
  • 13. Next Steps OpenGL bindings using NativeBoost done on Windows Stabilize API Adapt Morphic
  • 14. Opal We need a more flexible and simpler compiler Hooks for DSL support Better API New generation of tools
  • 15. Next Steps Decompiler (was the last missing bit) is nearly finished Soon added in 1.4 Throw away the old compiler Then improving the API
  • 16. Fuel: Fast Serialization Done by M. Diaz, M. Martinez-Peck, (T. Bourgeois & S. Ducasse) Don’t use ImageSegment (removed in 1.4) Fuel is faster (!!) Much more flexible and easier to understand
  • 17. Next Steps Replace existing serializers Migration path Binary code loader
  • 18. Scripting Syntax: Coral We want to write scripts in Pharo :) Headless REPL OS connexion (OSProcess for now) So we get Coral D. Pollet (and S. Ducasse)
  • 19. [ Console puts: 'Before the command'. ] [ "Let's define a command" | command | Console puts: 'duuuuhhh'. command := (CLICommandParser named: 'dostuff') aliases: #('dostuff.coral'); description: 'This command does a lot of stuff. I really mean a lot.'. ]
  • 20. Distributions: towards a certified catalog I want to go to Mars with just a DVD, and still be able to load the projects I want, and without internet, please!
  • 21. Process You use Metacello! You publish in your repo! When you want you can release code to a distribution All the code then is recursively copied to the distribution space All the tests and quality rules are checked People use your code but with a certain level of confidence :)
  • 22. Varia Making sure that we will be able to use announcements instead of SystemChangeNotifier Cleaning Morphic New package infrastructure
  • 23. Package certification Packages should be more self contained Tests LintRules Meta data Run and automatically certified
  • 24. Native Boost By Igor Stasenko (mac, linux and windows 32bits) Generate machine code on the fly :) Implement primitives FFI
  • 25. VM Expand knowledge Welcome newbies and idiots (like Stef) Increase tests Release VM builders from stupid tasks Traceability/Branding
  • 26. VM builds Anybody is now able to build a vm!
  • 27. VM Infrastructure VM validation after ANY changes Automatic recompilation Automatic test regressions
  • 28. Nautilus Throw away StringHolder hierarchy (Yes Browser inherits from StringHolder) Browser based on a model Nautilus by B. van Ryseghem
  • 30. Mini Image Pavel’s Mini image 4.2 mb for Seaside
  • 31. Future? Native boost Google native client Full bootstrap More secure system
  • 32. Pharo Consortium How to sustain Pharo? How to structure the community? Should we always rely on people free time?
  • 33. Consortium You can participate to the consortium: Pay a fee The consortium will pay a full-time engineer to support Pharo tasks
  • 34. When Started discussions with INRIA two years ago INRIA is ok to put money on the table (under negotiation) More than 25 companies are interested Join!
  • 35. Consortium FAQ Pharo will stay free! No negative impact: just a better Pharo People and organization should be able to pay too: a.k.a. Morale License
  • 36. Pharo books Pharo by example translated to french, merci! translated to spanish, gracias! japanese, german started
  • 37. New books are coming Pharo by Example Volume Two (deep into Pharo) Pharo for the Entreprise If you want to contribute... A glimpse at VM
  • 38. Doing a Master with us :) Slim binaries (compressing AST as bytecodes) Virtual Filesystem Fuel-ing the code Source manager Peer to peer sources NativeBoost as a foundational engine Bootstrap next steps
