  • 1. Getting Started with Cuis Smalltalk
  • 2. Getting Started with Cuis Smalltalk "Yay, Juan. You GO, guy! ...a great example of malleable software (and a clever mind) at work." Dan Ingalls "I like it... It's nice and clean and simple and pretty. Nice stuff!" Alan Kay "I think you have a very elegant design aesthetic." John Maloney "Cuis represents the best of Squeak: Elegant simplicity, high quality, and a sense of vision... I really do appreciate Cuis." "It has a clean, crisp feel and is a pleasure to use." David T. Lewis "It's one of the smallest, definitely the fastest, and probably the best structured (Squeak) kernel that has been built." Andreas Raab "If you would like to see Morphic done beautifully, ...check out Cuis. ...I simply cannot rave enough about how wonderful an experience it's been to work with." Casey Ransberger
  • 3. Getting Started with Cuis Smalltalk Who I'm? Germán S. Arduino ● Software Developer and Researcher ● Focused in Information Security and Special Projects ● Founder and Owner of Arduino Software ● Chief of R&D at Grupo Sancor Seguros ● Long time Smalltalker and loving it more each day ● About.me/garduino ●
  • 4. Getting Started with Cuis Smalltalk What is Cuis Smalltalk? A complete development environment written in itself ● A pure Object Oriented language ● A Smalltalk-80 environment derived from Squeak ● Simple, small, clean ● Open source, free and multiplatform ● Developed in Argentina by Juan Vuletich ● http://www.jvuletich.org/aboutMe.html
  • 5. Getting Started with Cuis Smalltalk How Cuis is different? ● Active attitude towards system complexity ● Code Quality ● Simplicity ● Code Management
  • 6. Getting Started with Cuis Smalltalk How Cuis is different? ● Cuis evolves in a controlled way. I can follow it! 2/3 mails / day are an average that permit me to keep updated with the Cuis progress and sometimes contribute!
  • 7. Getting Started with Cuis Smalltalk How Cuis is different? ● Cuis evolves in a controlled way. I can follow it! 2/3 mails / day are an average that permit me to keep updated with the Cuis progress and sometimes contribute! ● Compact Below 500 Classes, 100KLoC, 8MB base image (3,6MB after #reduceCuis) A comparison of number of classes: eToys 5.0: 2236 Squeak 4.4: 2511 Pharo 2.0: 3226 Cuis 4.2: 496
  • 8. Getting Started with Cuis Smalltalk Some of the main ideas and goals for Cuis: ● ● ● ● Close to the ideas in Smalltalk-80 and "Design Principles Behind Smalltalk" Includes only kernel functionality + dev tools Includes a greatly simplified and enhanced Morphic as the main UI Reasonably stable. Smalltalk kernel should not change much
  • 9. Getting Started with Cuis Smalltalk Some of the main ideas and goals for Cuis: ● Full support of Closures ● It works with Cog or Stack VM
  • 10. Getting Started with Cuis Smalltalk What is the audience? ● Smalltalkers who want a simple and consistent system they can really master ● ● ● Teachers and students learning Smalltalk Developers working for devices with little memory or CPU power People wanting to experiment with new directions in language design, UI frameworks, etc
  • 11. Getting Started with Cuis Smalltalk What is the audience? ● ● People wanting a reasonable kernel on which to build optional packages MicroISV programmers (See my talk “Smalltalk and MicroISV's”: http://www.slideshare.net/garduino1/smalltalk-andmicroisvs)
  • 12. Packages in Cuis ● ● The packages implementation in Cuis 4 is based in PackageInfo It uses Package names to prefix Classes and Methods categories ● More details in http://wiki.squeak.org/squeak/3329 ● Extension is .pck.st
  • 13. Code Management in Cuis Packages ● Code that is not part of the core image should be stored in packages (Examples: Applications, Frameworks, Libraries) Cuis Code ● Patches, fixes, code that is meant to be part of Cuis and that do not belong to any package is automatically stored in Change Sets
  • 14. Packages Dependency ● Packages implement provides / requires ● Packages can specify dependencies on features ● Include version / version.revision ● Automatically numbered by Cuis When a package is installed, its requirements are loaded in proper order ● A package may be installed using the FileList or from a workspace with ● Feature require: 'Swazoo'
  • 15. Code Management in Cuis
  • 16. Code Management in Cuis
  • 17. Code Management in Cuis
  • 18. ChangeSets (Cuis core code) ● Manages only code of Cuis Core image ● Code not in packages is captured into changesets ● Named in the form: 1827-CPUWatcherFix-GermanArduino-2013Sep19-09h20m-gsa.1.cs.st ● ● Managed automatically, not need of make them 'current' or 'active' (“make the changes goes to me”) Load changeset with 'FileIn' or 'Install'
