Item was removed: - ----- Method: TheWorldMainDockingBar>>welcomeToSqueak42 (in category 'submenu - help') ----- - welcomeToSqueak42 - ^'This is a list of the main achievements that went into the trunk image. - - Ready for next-generation VM - A new virtual-machine, known as "Cog", is about to be released for Squeak. It''s a complete rewrite from the ground-up, employing a Context-to-Stack mapping design onto which a JIT compiler for Intel-compatible hardware results in, roughly, a 3X, across-the-board performance improvement. Specific Benchmarks vary much more widely (from 1x to 5x, with some people claiming 10x for specifics. - - Significant class-library and IDE improvements - Many enhancements, fixes, documentation and performance improvements to the class-library and IDE tools. A new number parser allows greater flexibility in the expression of numbers. Finalization enhancements. - - An efficient window-resizing gesture allows Squeak windows to be quickly and easily manipulated, much like modern "tabletop" technologies. - - There were also many enhancements to the internal text editor. - - High-precision Clock - Squeak''s internal timer clock has been improved from millisecond to microsecond level precision. - - A Tidier image - A tidier image and code-base. Introduced a cleanUp protocol, removed the last direct users of CrLfFileStream, j3 support, SyntaxError, and more. Various packages and fonts can now be unloaded, if a smaller image is desired. - - The last of the underscore assignments have been replaced with ANSI assignments. - - There was also a significant refactoring and unification of Smalltalk and SmalltalkImage globals. - - stdio interface - Squeak now includes an API for accessing the operating system stdio (supported only on newer VM''s). - - Industrial command-line interface - The command-line interface has been improved to properly support relative-path qualification to the input script. - - Compatible with signature Squeak packages - This version of the Squeak platform is compatible with several unique packages like Croquet[*], Tweak, Seaside, muO, Magma, and more. See "Extending the System" under the Help menu for more information. - - Better Documentation - HelpSystem has been added to the core image to provide a light-weight framework for improved documentation. It can be accessed via Help>>Help Browser. Various bits of documentation, including how to load some important packages, has been added. - - SUnit - All test cases now have an associated timeout after which the test is considered failed. The purpose of the timeout is to catch issues like infinite loops, unexpected user input etc. in automated test environments. Timeouts can be set on an individual test basis using the <timeout: seconds> tag or for an entire test case by implementing the #defaultTimeout method. - - Graphics - Reading PNG images has been significantly sped up for some common cases. The improvements are in 50-200x range and heavily affect interactive uses of such files. - - Stricter Rectangles assert screen coordinate orientation. Empty Rectangles no longer #intersect: anything. - - Support for translucent fonts. - - MVC - Support for classic MVC has been restored to Squeak.
