FUNCTIONALITY CHANGES
|
|
|
|
- the help desk language level specific documentation has been
|
|
integrated into drscheme.
|
|
|
|
MINOR CHANGES AND BUG FIXES
|
|
|
|
- Only the platform-specific dialogs are used in drscheme now, on
|
|
all platforms. The preference has been removed from the dialog.

FUNCTIONALITY CHANGES
|
|
|
|
- the framework now imports a definition of the preferences
|
|
file location. Use this to have a separate preferences file
|
|
for each different application.
|
|
|
|
- do not use 'drscheme:settings anymore to get the current
|
|
language settings from drscheme. Now, use
|
|
|
|
drscheme:language:settings-preferences-symbol
|
|
|
|
(which is bound to the right symbol) instead.
|
|
|
|
- setup plt's ``clean'' info.ss flag does not recur
|
|
into subdirectories anymore.
|
|
|
|
MINOR CHANGES AND BUG FIXES
|
|
|
|
- Added Replace and Find again to edit menu
|
|
|
|
- changed `h' shortcut to find and replace again. show keybindings
|
|
has no shortcut anymore.
|
|
|
|
* Moved the filename and (define ...) popups to the left, swapping with
|
|
the Save button. (The popups in the middle of space look strange.)
|
|
|
|
* Merged the Project menu with the File menu.
|
|
|
|
* Changed the "Configure Language" menu item in the project window to
|
|
"Choose Language", to match the menu item in the file window.
|
|
|
|
* Add "..." to "Open Project" menu item.
|
|
|
|
* Got rid of "Insert Lambda". It's not nearly useful enough to be
|
|
worth all the bugs it creates. (Try inserting a lambda by itself and
|
|
hit return --- nothing happens. Try (<lambda>) --- bad selection for
|
|
the error message.)
|
|
|
|
* Give windows for untitled files/projects unique names: "Untitled 1",
|
|
"Untitled 2", etc.
|
|
|
|
* Fix multiple adjacent separators in the project window's File and
|
|
Edit menus.
|
|
|
|
* Dropped the old "platform independent" file dialogs, and use
|
|
get-file-list for projects.
|
|
|
|
* Disabled "Keybindings" menu item when not applicable.

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.

FUNCTIONALITY CHANGES
|
|
|
|
- added a "keymap" menu to the edit menu (shortcut: k)
|
|
that opens a window where you can see all of the key
|
|
bindings' names and short cuts, and you can choose one
|
|
to invoke.
|
|
|
|
- framework:
|
|
- added canonicalize-keybinding-string
|
|
- added aug-keymap%, aug-keymap<%>
|
|
- editor:basic now sets it's keymap to an
|
|
aug-keymap<%> during initialization.
|
|
|
|
MINOR CHANGES AND BUG FIXES
|
|
|
|
- added a "Kill" menu item that kills all computation and reclaims
|
|
all resources from the program that drscheme is executing.
|
|
This is useful for multi-threaded apps that get out of hand.
|
|
|
|
- improved the look of the "(define" (now "(define ...)") and
|
|
filename buttons on the left in drscheme's toolbar
|
|
|
|
- if ``#!'' appears at the beginning of the first line in the definitions
|
|
window, the first line is treated as a comment during execution
|
|
(this is only a change for the non-debug language levels -- the
|
|
teaching and debug language levels all already did this)
|
|
|
|
- meta-control-d, meta-control-u, meta-shift-control-d, meta-shift-control-u
|
|
keybindings all restored.
|
|
|
|
|
|
102d7
|
|
|
|
- drscheme now has a little button on the bar that lets you hop
|
|
around between definitions in the program. It is approximate in
|
|
that it doesn't really know every detail about the lexical
|
|
structure of scheme, but it should still be quite useful.

FUN INFO
|
|
|
|
- DrScheme's rep class now exports a method with this type:
|
|
|
|
((((-> void) -> void) -> void) -> void)
|
|
4 3 2 1
|
|
|
|
believe it or not. It is used to evaluate user expressions in the
|
|
repl. Arrow 1 sets up the repl (watch cursor and stuff) and then
|
|
calls arrow 2, which should loop, once for each expression (say in
|
|
the definitions window), calling arrow 3. Arrow 2 then calls arrow 3
|
|
with arrow 4. Arrow 3 does a little before/after setup to get
|
|
breaking right and calls arrow 4 to actually evaluate each
|
|
expression.
|
|
|
|
FUNCTIONALITY CHANGES
|
|
|
|
- the framework's info frame mixins no longer require frame:editor<%>
|
|
as an input. Also, they are moved lower in the hierarchy of the
|
|
instantiated mixin classes in the framework. This affects all of the
|
|
frame:XX% classes.
|
|
|
|
- project manager windows now have a repl.
|
|
The repl shows the values returned by loading each of the files
|
|
in the project.
|
|
|
|
tools:
|
|
|
|
- ensure-interactions-shown is now ensure-rep-shown
|
|
- do-many-buffer-evals is now do-many-text-evals
|
|
|
|
teachpacks:
|
|
|
|
- interactions window now shows the names of the teachpacks that
|
|
were installed at last execute.
|
|
- teachpack names are not in the area with the execute button, instead
|
|
they are now shown in the language menu.
|
|
- it is now an error to add the same teachpack twice.
|
|
|
|
- GRAPHICAL_DEBUG is no longer supported. It was always wierd, becuase
|
|
it changed the semantics of require-library in a way that was
|
|
mostly the same, and keeping drscheme in the consistent
|
|
intersection of the two semantics was getting painful (not to
|
|
mention confusing...)
|
|
|
|
MINOR CHANGES AND BUG FIXES
|
|
|
|
- repl errors that are in some loaded file have little clickable
|
|
icons that open the file and show the error's source location in
|
|
the file. Icon suggestions welcome. To test them out, just replace
|
|
file.gif in the icons collection.
|
|
|
|
- common file dialog keyboard navigation improved (typing letters now
|
|
may go backwards now -- before it only went fowards)
|
|
|
|
- common file dialogs are now resizable.
|
|
|
|
- common file dialogs now sort in case insensitive mode always
|
|
(typing letters doesn't make much sense otherwise)
|
|
|
|
- lucky search now sets the focus to the html viewing canvas instead
|
|
of leaving the focus on the search text-field.

FUNCTIONALITY CHANGES
|
|
|
|
- THE FILE FORMAT FOR PROJECT FILES HAS CHANGED
|
|
|
|
to update your old project files to the new format, use emacs or
|
|
something to insert a ' at the front of the file. Then open and
|
|
save the project in drscheme.
|
|
|
|
- project files are now `load'able. That is, if you have the right
|
|
language settings, you can do
|
|
|
|
mzscheme -qmvr myproj.proj
|
|
|
|
and have the same effect as clicking execute on the project
|
|
window. For mred, you will need to do something like this:
|
|
|
|
mred -qmvr myproj.proj -e "(yield (make-semaphore 0))"
|
|
|
|
so that mred doesn't quit automatically.
|
|
|
|
MINOR CHANGES AND BUG FIXES
|
|
|
|
- typeset now uses scheme-mode editors for red boxes.
|
|
|
|
- Help Desk now has a "feeling lucky" option ala google (menu
|
|
shortcut: l). It goes directly to the first item that would have
|
|
been found in a regular search.
|
|
|
|
- Clicking on an error message link in drscheme now uses the "feeling
|
|
lucky" style search in help desk.

|
|
|
|
- clever-file-format now symetrically changes the file's format to
|
|
'standard. It used to rever the file format to 'text when there
|
|
were no more images in it. Now, it also changes back to non-'text
|

when images (and other non-string-snips) are added back.
|

|
|
gui-utils:get-snips/chars-from-text

|
|
|
- zodiac now supports graphical expressions. If a snip implements
|
|
zodiac's expand<%> interface, zodiac calls a method of the snip to
|
|
expand it. Docs updated but not built.
|
|
|
|
- the teaching languages now come with:

|
|
|
make-posn, posn-x, posn-y, and posn?
|
|
|
|
by default (no library required).
|
|

|
|
plt/collects/typeset
|
|
plt/collects/drscheme/tools/typeset
|
|
|
|
be sure to check those out. Search for Typeset in help desk for
|
|
more info.
|
|
|
|
- teaching levels print exact numbers whose denominators are evenly
|
|
disivible by 2 and 5 as decimals.
|
|
|
|
- teaching levels treat input decimals as exact numbers.
|
|
|

- fixed a bug (PR 1297, steck submission) in a call to message-box
|
|
from the get-file dialog but was unable to repdoduce the bug. Paul,
|
|
can you see if the bug has gone away? Thanks.
|
|
|
|
- changed the new version "welcome to drs" window back to something
|
|
much like the one in previous versions.
|
|
|
|
- drscheme should now print with a fixed-width font.
|
|
|
|
- in the main help-desk window, space does pgdn and backspace does
|
|
pgup, ala netscape. Also, typing return or enter while the cursor

FUNCTIONALITY CHANGES
|
|
|
|
- New project manager. The manual is not yet available, so
|
|
you will have to play with the Project menu yourself. I hope that
|
|
things are self-explanatory. There is no REPL support. Any repl
|
|
support that comes will be part of the debugger.
|
|
|
|
*** WARNING: NEW DIRECTORY ***
|
|
|
|
To get it, run these simple commands:
|
|
|
|
% cd PLTHOME/collects/drscheme
|
|
% cvs update -r exp -d
|
|
|
|
- added class/d macro. It's syntax is like that for a unit, but it
|
|
defines a class. Roughly:
|
|
|
|
(class/d
|
|
super-expresion
|
|
init-args
|
|
((public var ...)
|

(override var ...)
|

(inherit var ...)
|
|
(rename (var var) ...))
|
|
|
|
definitions-and-expressions ...)
|
|
|
|
- the drscheme:get/extend:extend-* functions no longer haver %s at
|
|
the end of their names.
|
|
|
|
MINOR CHANGES AND BUG FIXES
|
|
|
|
- bug report form cleaned up.
|
|
|
|
- improved the welcome window (merged with about box)
|
|
|
|
|
|
Version 101:
|
|
|
|
General
|
|
-------
|
|
|
|
- The teaching libraries are now called teachpacks. See the teachpack
|
|
release notes for more information.
|
|
|
|
- DrScheme's languages have changed (again). The langauges are now:
|
|
|
|
- Beginning Student
|
|
- Intermediate Student
|
|
- Advanced Student
|
|
- Full Scheme, which contains:
|
|
- Graphical Full Scheme (with and without debugging), and
|
|
- Textual Full Scheme (with and without debugging)
|
|
|
|
- Help Desk now supports bug report submissions. Please use it in
|
|
favor of the web based form. To submit a bug, follow the "Sumbit a
|
|
Bug" link near the bottom of Help Desk's front page
|
|
|
|
- On European keyboards, the backslash character
|
|
may not work properly in DrScheme. If you
|
|
experience this problem, comment out this line:
|
|
|
|
(map-meta "\\" "remove-space")
|
|
|
|
in PLTHOME/collects/framework/keymap.ss.
|
|
|
|
- For tools, invoke-library is now called invoke-teachpack.
|
|
|
|
- Renamed two files in the graphics collection:
|
|
graphic.ss is now graphics.ss
|
|
graphics.ss is now graphicss.ss
|
|
|
|
- DrScheme's print menu now inserts the time, date and filename in the
|
|
header of the file to be printed.
|
|
|
|
- comment/uncomment is improved. Now, it blindly adds a semicolon to the
|
|
front of each line (and doesn't add extra semicolons on following lines)
|
|
and aways removes one semicolon (if present) from the front of each line.
|
|
|
|
- Parenthesis highlighting now turns unmatched parens red
|
|
in addition to turning matched parenthesis regions grey.
|
|
Also (now that the caret flashes) if the caret is between two
|
|
parens, both before and after parens will be highlighted,
|
|
not just the ones before.
|
|
|
|
Thus, every time the cursor is next to an uncommented
|
|
paren, the programmer sees some feedback about the paren.
|
|
|
|
Version 100:
|
|
|
|
General
|
|
-------
|
|
|
|
- DrScheme's languages have changed. The new languages are:
|
|
|
|
- Beginner
|
|
- Intermediate
|
|
- Advanced
|
|
- MzScheme
|
|
- MrEd
|
|
|
|
The first three languages are essentially the same as in version
|
|
53, except that graphics primitives have been removed. (Instead,
|
|
domain-specific graphics commands can be loaded as libraries.) The
|
|
turtles remain in the advanced language.
|
|
|
|
The MzScheme and MrEd languages match exactly the languages
|
|
provided by the MzScheme and MrEd executables.
|
|
|
|
- A simple algebraic stepper, dubbed The Foot, is now available. The
|
|
Foot permits users to construct a source-level evaluation trace for
|
|
programs written in the Beginner language. It will be expanded in
|
|
future releases.
|
|
|
|
- DrScheme's Help Desk provides online help for DrScheme, its
|
|
languages, and its libraries.
|
|
|
|
- Graphics functions were removed from the teaching languages
|
|
(Beginner, Intermediate, and Advanced), except Turtles in
|
|
Advanced. To use graphics functions, you must select a library (and
|
|
the teaching libraries are not yet updated).
|
|
|
|
- The old viewport-based graphics library can be loaded into the MrEd
|
|
Debug language via (require-library "graphic.ss" "graphics").
|
|
|
|
- I/O within DrScheme is substantially improved.
|
|
|
|
- The library and tool interfaces for extended DrScheme have
|
|
changed.
|
|
|
|
|
|
Version 53:
|
|
|
|
General
|
|
-------
|
|
|
|
- view menu items now have accelerators
|
|
|
|
- (<= exp) isn't allowed in beginner. (same for <, >, and >=)
|
|
|
|
- print primitive is now setup correctly to print based on the language level
|
|
|
|
- paren-matching in semi-colon comments is disabled
|
|
|
|
- info panel "running" message is now aligned correctly
|
|
|
|
- The check synatax and analyze buttons are now disabled during evaluation
|
|
|
|
- library directory now starts in "MZLIB_COLLECTS_DIR/../../lib"
|
|
which is our best approximation to "PLTHOME/lib"
|
|
|
|
- elevator library can now select more than one floor at a time
|
|
|
|
|
|
Version 52:
|
|
|
|
General
|
|
-------
|
|
|
|
- The words "running" or "not running" at the bottom of the
|
|
DrScheme frame indicate whether or not work is happening in the
|
|
user's program.
|
|
|
|
- a "Windows" menu has been added which keeps track of the currently
|
|
open drscheme windows.
|
|
|
|
- the source locations for "load"ed files now match the numbers
|
|
in the bottom of the drscheme window.
|
|
|
|
- the thread that evaluations (including execution) take place on is
|
|
the same as the eventspace's main thread, unless the evaluation
|
|
thread is killed. In that case, the eventspace's main thread is
|
|
re-generated, but the execution thread does not.
|
|
|
|
- The REPL implementation has been cleaned up.
|
|
|
|
- the turtles window does not survive across executions anymore
|
|
|
|
- the Quasi-R4RS language level has been renamed to R4RS+
|
|
|
|
DrScheme Tools/Libraries
|
|
------------------------
|
|
|
|
- new methods on rep:edit%: report-exception-error accepts an exception and
|
|
prints the error message in the console.
|
|
|
|
- send-scheme is outdated. Use run-in-evaluation-thread instead
|
|
|
|
- the drscheme:tool^ signature has changed. A new subunit, "basis" has
|
|
been aded and the process-finish struct is now in that subunit. So,
|
|
drscheme:language:process-finish? becomes
|
|
drscheme:basis:process-finish?, etc.
|
|
|
|
The process-finish structure no longer has a boolean indicating sucess.
|
|
Instead, an exception is raised.
|
|
|
|
|
|
- the settings for the language have been re-aranged
|
|
- there are two new parameters, exported from the basis
|
|
subunit of drscheme:export^, current-setting and current-vocabulary
|
|
- current-vocabulary contains the vocabulary that zodiac uses to
|
|
perform macro expansion
|
|
- current-setting is bound to a setting struct, which encapsulates
|
|
all of the information about the language level
|
|
- the process-*/zodiac and process-*/no-zodiac proceudres
|
|
are no longer methods and their arguments have changed
|
|
|
|
|
|
Version 51:
|
|
|
|
General
|
|
-------
|
|
- fixed error message for "eq?" and "cons" at beginner level.
|
|
|
|
- check syntax does not work with an unitialized repl when:
|
|
the source contains define-macro. (won't be fixed in the release)
|
|
|
|
- eval no longer loops forever in mred vocabulary
|
|
|
|
- searching keybindings have changed. There are four distinct actions:
|
|
action1: move keyboard focus to the searching window, opening it if necessary,
|
|
or if already there search forward
|
|
action2: move keyboard focus to the searching window, opening it if necessary,
|
|
or if already there search backward.
|
|
action3: search again, in the same direction
|
|
action4: move the focus between the main window, searching window and replacment window
|
|
action5: hide the searching window
|
|
|
|
The actions are mapped to different keys, based on the platform.
|
|
|
|
On unix:
|
|
action1 => control-s, meta-%
|
|
action2 => control-r
|
|
action3 => f3
|
|
action4 => control-i
|
|
action5 => control-g
|
|
|
|
On the macintosh:
|
|
action1 => command-f
|
|
action2 => command-r
|
|
action3 => command-g
|
|
action4 => command-o
|
|
action5 => command-.
|
|
|
|
On windows:
|
|
action1 => control-f
|
|
action2 => control-r
|
|
action3 => f3, control-g
|
|
action4 => control-i
|
|
action5 => escape
|
|
|
|
- turned off the file name printouts on splash screen
|
|
|
|
evaluate:
|
|
(wx:write-resource "mred" "splashMessages" 1 (wx:find-path 'setup-file))
|
|
to turn them back on.
|
|
|
|
- fixed a bug that caused error messages to be displayed in message
|
|
boxes more often than neccessary. (as opposed to printing in the
|
|
repl)
|
|
|
|
- parenthesis matching is improved
|
|
|
|
- The empty list is now called "empty" instead of "null" with the
|
|
constructor style printer.
|
|
|
|
- The analyze button puts up a dialog saying "please wait, loading",
|
|
now.
|
|
|
|
- the fonts dialog now shows previews of the selected fonts. You
|
|
still need to restart to see the changes, unfortunately.
|
|
|
|
DrScheme Tools/Libraries
|
|
------------------------
|
|
|
|
- tools must now import wx names explicitly, as a new first import.
|
|
|
|
- the parameters interface has changed. Instead getting and setting
|
|
the class, the tool programmer must register a function that
|
|
accepts a class and returns a class. See the manual for more
|
|
details.
|
|
|
|
- process/zodiac-finish has been renamed to process-finish
|
