Pharo Status
- Pharo is an open-source Smalltalk environment that is highly active with many contributors and projects. It has a large community and is used both for academic research and commercial applications. - Pharo 3 was recently released in April 2014 and included many improvements and changes while remaining easy to adopt. Development is already underway on Pharo 4, with additional changes planned. - Upcoming work includes first-class variables to improve reflection, a new one-file image format, and advanced reflection capabilities using meta-objects. The goal is to continue enhancing Pharo's functionality while keeping it approachable.

- 31. Pharo Status MarcusDenker http://www.pharo-project.org
- 32. Pharo3: Release April`14 Started March 2013 ! 2390 Issue tracker entries with Pharo3 tag closed ! 854 Updates
- 33. Iceberg A lotof Changes! Not everything visible
- 34.
- 35. A lot ofChange!
- 36. Yet easy toadopt Moose switched in two afternoons (two people) ! Others: “I just loaded my packages"
- 37. Infrastructure: CI https://ci.inria.fris stable and used a lot ! Every fix is validated automatically before human review Every update triggers test run on 3 Architectures over 80 projects in pharo-contribution
- 38.
- 39. Infrastructure: Misc http://files.pharo.org ! http://get.pharo.org ! SmalltalkHub: http://smalltalkhub.com 1411 users, >1200 repos
- 40. Small Stuff Lotsof Cleanups ! Lots of tuning (perfomance, memory) ! Lots of small improvements
- 41. Lots of largerthings Closure class now standard in Pharo3 Terminal output for stderr Cleanup Source file related code AST Interpreter AST based Navigation in Browser Komitter Launcher Font Speedup ….
- 42. New Inspector UnifyInspector and Explorer Make specialised inspectors visible
- 43. Athens: Vector Graphics New API for Vector Graphics Independent of Backend For now: Cairo Balloon3D for Debugging Future: OpenGL
- 44.
- 45. Opal Compiler UsesRB AST ! IRBuilder: Bytecode backend with high-level builder Much easier to change Basis for advanced Reflection
- 46. New ClassBuilder Replacesthe old ClassBuilder ! Easier to understand and more flexible ! Basis for First Class Variables (Slots)
- 47. New Debugger Modelnow separate from View ! Model is scriptable ! Debugger is extensible with Commands
- 48. Command Line denker$./pharo Pharo.image --list! Currently installed Command Line Handlers:! Fuel Loads fuel files! config Install Configurations! save Rename the image and changes file! update Load updates! printVersion Print image version! st Loads and executes .st source files! test A command line test runner! clean Run image cleanup! eval Directly evaluates one line scripts! !
- 49. A lot ofchange…
- 50. But just oneiteration
- 51.
- 52. Pharo4 Again: Tobe released Spring 2015 Already 175 updates 480 Issues closed Very stable
- 53. For example… ImprovedRefactorings 6MB Deployment Image ifTrue: on non-Booleans Browser and Tool cleanups Context Cleanup (MethodContext/ContextPart merge)
- 55.
- 56. First Class Variables • First class Instance Variables (Slots) ! • First class globals + class variables
- 57. For what? •Allows programmers to define behavior • Easy reflection on variable access • Break on variable read, for example
- 58. Property Slots Object subclass: #PropertyObject layout: PointerLayout slots: { #ivar. #property1 => PropertySlot. #property2 => PropertySlot. ... #propertyN => PropertySlot. }
- 59. Property Slots Object subclass: #PropertyObject layout: PointerLayout instanceVariables: { #ivar. #property1 => PropertySlot. #property2 => PropertySlot. ... #propertyN => PropertySlot. }
- 60. Examples • BitSlot • BooleanSlot • Alias • Relationships (e.g. one-one, one-many) • …. Your Domain level Slot! ==> Magritte
- 61. More in Paperfrom OOPSLA
- 62. Advanced Reflection •Partial Behavioral Reflection • Associate MetaObject with structural object • Slots, Globals • AST nodes
- 63.
- 64. Why? • Changebehaviour for selected AST Nodes or Variables • “All variable reads” • “this message send” But without changing the program code!
- 65. Uses… • Debugger • BreakPoints, WatchPoints • Profilers • Coverage Analysis • AOP
- 66. One File Pharo • .sources, .changes. .image ! • It is time to simplify that!
- 67. Epicea • Replace.changes • High level model: • aggregate changes (refactoring) • serialized to disk independent of source model
- 69. Sources • Itis 2014: Memory is cheap. • Complexity is expensive • Why not just put the sources in the image? • Externalize when needed (small devices) • Code history is in Monticello (or Git)
- 70. Bootstrap • Createan image from a git repository • Control what the image contains • Easier to make changes • Enforces Modularity
- 71. Boostrap • Workingfor Pharo3 as a prototype ! • Can we even use this for Pharo4 on the build server?
- 72. And more… •GT Tools • VM related news • Spur, Sista, 64bit… • ……….. there are lots of talks here
