From: Robert Bruce Findler <firstname.lastname@example.org> To: email@example.com Date: Sat, 20 May 2000 14:13:07 -0400 Subject: 102d9 The exp-tagged source (in CVS) for DrScheme is now version 102d9: NEW DIRECTORY: plt/collects/defaults be sure to get the new directory with: cvs update -d plt/collects/defaults or DrScheme will fail to start up. WARNINGS: - this release breaks the stepper. - the "create launcher" menu item is not yet fully functional, so use at your own risk. PRS: 1424, 1437 FUNCTIONALITY CHANGES - drscheme-jr now supports teachpacks (those that don’t use GUIs, like htdp/dir.ss) - the graphics library (sometimes known as sixlib) no longer accepts any scaling arguments. - drscheme:rep:process-text/zodiac and drscheme:rep:process-text/no-zodiac are now called drscheme:load-handler:process-text/zodiac and drscheme:load-handler:process-text/no-zodiac. - Windows and unix launchers can now be run from any directory. They do not need to be saved in a particular place (this has been true for some time, but it is officially true now.). - the debug full scheme languages now allow loading of files that contain graphics. - the framework’s preferences system now requires you to set the marshall/unmarshalling functions (if any) before setting the default preference. - drscheme now supports site-specific default preferences. To use, create a file prefs.ss in the defaults collection that is a copy of the preferences file that you want to be the defaults. Then, if the user-specific preferences file doesn’t exist (or the preferences in it are from an old version), the contents of the prefs.ss file in the defaults collection is used as the preferences. - drscheme now wraps uses with-handlers so that if a tool signals an error when it is loaded or invoked, it just puts a window with the error message and continues, instead of keeping drscheme from starting up. - the .plt installer no longer automatically deletes compiled files when installing a .plt file. - setup-plt now uses the ’clean flag in info.ss to determine the files to be deleted when --clean-ing a collection. It defaults to the files in the "compiled" sub-collection of a collection. - setup-plt no longer automatically runs --clean when installing a .plt file. MINOR CHANGES AND BUG FIXES - the searching dialog now has two-line find and replace editors. - #! is treated like a comment when executing the defintions window, if it is the first two characters in the definitions window. - constructing the project manager’s "collection projects" menu was adding something like a 25% overhead to drscheme’s startup, so that menu is gone (I doubt anyone really used it anyway...) - rarely used save menu items relegated to sub-menu. - wrap text is now a checkable item that is checked when the editor is wrapped. - drscheme-jr now has a doc.txt file that explains its implementation. The implementation was factored so that DrScheme’s new launchers can re-use drscheme-jr’s implementation. So, if you change drscheme-jr, be aware that you might affecting these launchers.
