Summary: artwork?

Initial Comment:
It would be nice if DrJava had a logo, icons, etc.  
Just to create some sort of identifying look...

Just a thought :-)

Summary: "No disk in drive" errors on Windows

Initial Comment:
Sometimes, when you start DrJava on windows platforms, you get a number of error messages 
saying "no disk in drive" for A: or some other weird "drives".

(The code, of course, is doing nothing to drive A:.)

I found this reference to the problem on the Web, and I think it's the same problem wer're seeing:

Applications that use a security manager on Microsoft Windows can run into a
problem in which JFileChooser asks to access a disk in drive A:. When
trying to save from an application, and after going through the security warning
dialog, a message such as the following may appear: "There is no disk in
the drive. Please insert a disk into drive A:." This problem is
being tracked in bug report 4512661, currently not on the Bug Parade web site.

Well, since we don't really need the security manager (see bug #512016), perhaps we should just 
get rid of it, which will hopefully resolve the problem.

   Just to follow up...  If anyone else has problems like this, be sure 
you're using the most recent version of ant.  ant-1.4.1 was released a 
little while ago, and you'll need it for ant to work with JDK 1.4.

In fact, it's the default now if you use the standard environment I set
up.

Thus far I have successfully seen tests pass on Linux 1.4 (my PC) and
Solaris 1.4 (jungle.owlnet). This is not surprising since it's almost the
same code as 1.4-rc was. :)

Have you tried running the tests with it yet?  I'm not sure if it's a 
problem with my setup, but when I run "ant test" in jdk 1.4, I get a 
not-so-happy exception right away:

class sun.reflect.GeneratedSerializationConstructorAccessor6 cannot 
access its superclass sun.reflect.SerializationConstructionAccessorImpl

The tests run fine in jdk 1.3, obviously.

Anyway, aside from that, I've been using it in Linux, and I'm very happy 
with it.

Summary: Traditional toolbar and status bar

Initial Comment:
The Save and Compile buttons currently in the 
menubar should be moved to a toolbar with icons, 
which should also include buttons for (at least) 
New, Open, Cut, Copy, Paste, and perhaps Undo, Redo, 
and Find/Replace.  Ultimately, this toolbar might be 
configurable (within the new configuration engine); 
this is up for discussion.

Also, the full path to the file should be moved to a 
traditional status bar at the bottom of the window.

Summary: Hard to create .drjava on Windows

Initial Comment:
Windows doesn't like files that start with a dot very 
much. In particular, you can't rename a file in 
explorer to begin with a period.

For now, to get around this problem, we'll 
automatically create the .drjava file if it doesn't 
exist. Then the user only has to edit it, not create 
it.

Summary: modify classpath within DrJava

Initial Comment:
One should be able to modify the classpath dynamically
within DrJava, instead of having to use the command
line.  It'd be convenient, and it would make it easier
to use DrJava on OS's that are purely or predominantly
graphical, like Windows and Mac OS <10.

Summary: Non-Modal Find/Replace

Initial Comment:
The current find/replace dialog is application-modal, i.e. the user cannot interact with the primary window while the dialog is open.  This is unneccessarily limiting.  Furthermore, many of the individual operations offered by the dialog could be implemented as menu options with keyboard shortcuts.  For example, the Find command could have two triggers: one would open the dialog with the search field automatically populated with the current text selection, and the second would skip the dialog entirely and execute the search.  Find Again, Replace, Replace and Find Next, and Replace All could be implemented in similar fashion.

The Find Panel offered by MacOS X (e.g. in TextEdit) is an example of these features.  (It also includes many more, such as selection-scoping for Replace All and both forward and backward searches.)  Other possible options include escape sequence support for identifying special characters, file-spanning searches, "offline" Replace All for files on disk which have not been opened, larger input boxes in the dialog, selectable case-sensitivity, and/or "live" searches (e.g. Emacs I-search).

Summary: Ugly Panel Borders

Initial Comment:
Under MacOS X 10.1.2 Aqua L&F using drjava-20020129-1635.jar, several levels of layered borders appear around the main code text area.  This is extremely ugly and unnecessary.  Perhaps this could be resolved by manually clearing the borders from these JPanels.

Opening a new file seems to "deactivate" the scrollbars of previous windows, i.e. the scrollbar is displayed and updated, but it is "greyed out" and doesn't respond to user clicks.  This behavior has been confirmed on MacOS X 10.1.2 using the Aqua L&F.  Other platforms haven't been tested yet.

Summary: Get rid of PreventExitSecurityManager

Initial Comment:
Now that the interpreter runs in its own JVM, there is
no need to use the PreventExitSecurityManager. This
comes up in a few cases: When you try to exit JUnit's
Swing UI, and when you hit Command-Q to kill DrJava on
the MacOS.

Instead of the present model (System.exit fails unless
it's called from DefaultGlobalModel.exit()), I think we
should set up an OnExitRegistry, which stores Command
objects to be executed just before System.exit. Then
GlobalModel would register a command to do the
requisite cleanup before quitting (and BTW, the
Registry has to allow the commands to veto the exit).

Then, calls to System.exit() would be OK.

Well, wait -- then how, in the test cases where there
are many GlobalModel objects, would the defunct global
models be prevented from being checked upon exit? By
using a weak reference to the global model? Hmm. This
may not be worth it after all.

Summary: Multiple File Open

Initial Comment:
In Windows, it's standard to Ctrl-Click to select 
multiple files (one at a time) or Shift-click to 
select a range of files.  Macs have something similar, 
although I'm unaware of any analogue on Unix.

It'd be great to capitalize on this to allow DrJava to 
open many files at once.

Summary: JUnit integration.

Initial Comment:
Offer some sort of "Debug>Graphic" "Debug>Text" integration with JUnit for easy unit testing.  I don't think it should be integrated TOO heavily, but for those who wish to use Unit tests it could be a great help.

It seems this might be tricky to do, but hey, we're supposed to be dreamers.  I know Eclipse has this feature.

You can always add something to DrJava's classpath by

I'll do that.

Summary: Make GJv6 not show up in list on 1.4

Initial Comment:
GJv6 will not work on JDK1.4 due to class file version
disagreements. (GJ requires <= 45.3, JDK1.4 use 48.0.)
This could be fixed in the GJ code if we cared, but we
don't.

So, at the very least, the GJ compiler adapter should
detect that it's on a too-late JDK and just not load.

Summary: find/replace is broken

Initial Comment:
In the latest build (drjava-20020124-1707.jar)
under Sun JDK 1.3.1_01 on Linux 7.1, the find/replace
command hangs after a blank pop-up window comes up.

Under Sun JDK 1.4 Beta, the find/replace window
comes up, and the buttons in the window do roughly
the right thing with the following bugs:

1. Replace moves the focus back to the beginning of the
   file instead of leaving it over the replaced item.

2. Replace&FindNext moves the focus back to the
   beginning of the file.  I don't know where the 
   cursor is after executing the command because I 
   can't see (the scroll bar is locked), but repeatedly
   hitting this button skips over some occurrences of
   the search key.  When the end-of-file is reached
   and wrap around is offerred, wrap around does not 
   always occur.  In addition, wrap around is not always
   offered the first time end-of-file is reached.


I am attaching the file in which I encountered these
problems.  Try replacing each occurence of ConvForm by
Convert (but not by using the ReplaceAll command which
I consider too dangerous because of false matches) by
Finding the first occurrence and then using
Replace/FindNext.

As of DrJava-20020124-1713:

I am not sure yet what caused this, but I just got this
exception thrown when compiling a file.

The file I was compiling is attached. The exception
came when using a non-GJ compiler to compile.
