PLT Scheme ReviewThanks for the update , but ... - Version: 370, 8/4/2007 01:57PM PST

Edwin-schemer
As previously noted, the distribution still creates a folder with the version number, so when moved, e.g., to the ~/Applications subdirectory it still does not overwrite the older version, and thus requires making a new link into the Dock.
Otherwise it is probably the best programming environment, which both my 11-year-old grandson and any experienced Lisp/Scheme programmer can enjoy on any platform.

Highlights from the mailing list archive:
  • Mac OS X installation is drag-and-drop
  • Tools that create executables can produce self-contained packages
  • ProfessorJ now supports a unit testing mechanism and a new wizard for generating class and union declarations
  • The draw library now accommodates multiple worlds, and a new idraw library supports imperative drawing and animation.
  • MzScheme includes a just-in-time compiler on x86, x86_64, and PowerPC platforms
  • MzScheme's default exception handler now shows stack-trace information
  • DrScheme now treats open square-bracket keyboard input specially for less wear and tear on your hands

PLT Scheme CommentarySuggestion to developers - Version: 300, 12/18/2005 11:37AM PST

The product is getting better with each update.
I have one wish/suggestion: the installer should be able to replace the previous
version, rather than install the new version in addition to the old one.
For those of us with smaller disks (< 30 GB) adding an extra 66 MB with each update matters!
In addition, when you remove the old version its icon in the Dock
points to a nonexisting application.
