Wxpython Implemented on Windows CE, Source code

Added brace highlighting.  (Thank you, Kevin Altis.)

Fixed problem displaying unicode objects in ``PyFilling``.

Changed how ``filling.py`` checks for expandable objects.  Lists are
now expandable objects.

Made the key handling more robust when there is an active text
selection that includes text prior to the last primary prompt.  Thanks
to Raul Cota for pointing this out.

Fixed wxSTC problem with brace highlighting and non-us keyboards.
(Thank you for the patch, Jean-Michel Fauth.)

Added ``busy = wxBusyCursor()`` to key points in ``shell`` and
``filling``.

Added ``OnCloseWindow`` handler to ``ShellFrame`` and ``CrustFrame``.

Default to ``SetWrapMode(1)`` for shell and namespace viewer.

Added ``shell.wrap()`` and ``shell.zoom()``.

Added autoCompleteKeys hooks for Raul Cota.

Cleaned up various little key handling bugs.

Changed input methods to get values from shell, rather than dialog
boxes.  Renamed ``readIn`` to ``readline`` and ``readRaw`` to
``raw_input``.


0.7.1 (12/12/2001 to 2/21/2002)
-------------------------------

Fixed ``OnChar()`` issues effecting European keyboards, as reported by
Jean-Michel Fauth.

Fixed ``introspect.py`` issue with xmlrpc objects reported by Kevin
Altis.

Fixed some introspect/PyFilling issues with regard to Python 2.2.

Fixed font background color as reported by Keith J. Farmer.  (Thanks)

Fixed problem with call tips and autocompletion inside multiline
commands as report by Kevin Altis.

Improved ``OnKeyDown`` handling of cut/copy/paste operations based on
feedback from Syver Enstad.  (Thanks)

Added a ``shell.help()`` method to display some help info.

Changed sort of items in the namespace viewer to case insensitive.

Changed ``attributes.sort(lambda x, y: cmp(x.upper(), y.upper()))`` in
advance of an upcoming fix to an autocompletion matching bug in wxSTC.

Improved support for ZODB by allowing namespace drilldown into BTrees.

Added ``shell.PasteAndRun()`` to support pasting multiple commands into
the shell from the clipboard.  Ctrl+Shift+V or v.

Enter now always processes a command (or copies down a previous one.)
To insert a line break, press Ctrl+Enter.

Escape key clears the current, unexecuted command.

History retrieval changed to replace current command.  Added new keys
to insert from history - Shift+Up and Shift+Down.

Better call tips on objects with ``__call__`` methods.

Improved call tip positioning calculation.


0.7 (10/15/2001 to 12/11/2001)
------------------------------

Changed how command history retrieval functions work.  Added Alt-P,
Alt-N as keybindings for Retrieve-Previous, Retrieve-Next.

Added full support for multi-line commands, similar to IDLE.

Changed ``introspect.getAttributeNames()`` to do a case insensitive
sort.

Changed Cut/Copy/Paste to deal with prompts intelligently.  Cut and
Copy remove all prompts.  Paste can handle prompted or not-prompted
text.

Added ``CopyWithPrompts()`` method attached to Ctrl-Shift-C for those
times when you really do want all the prompts left intact.

Improved handling of the shell's read-only zone.

Changed ``CrustFrame.__init__`` parameter spec to include all
parameters allowed by a ``wxFrame``.

Changed ``FillingText`` to be read-only.

Renamed ``PyCrust.py`` to ``PyCrustApp.py`` to eliminate
package/module name conflicts that kept you from doing ``from PyCrust
import shell`` inside files located in the ``PyCrust`` directory.

Renamed ``PyFilling.py`` to ``PyFillingApp.py`` and ``PyShell.py`` to
``PyShellApp.py`` to maintain consistency.

Removed the ``__date__`` property from all modules.

Fixed bug in ``introspect.getCallTip()``, reported by Kevin Altis.


0.6.1 (9/19/2001 to 10/12/2001)
-------------------------------

Changed ``Shell.run()`` to always position to the end of existing
text, as suggested by Raul Cota.

Changed ``introspect.getAllAttributeNames()`` to break circular
references in ``object.__class__``, which occurs in Zope/ZODB
extension classes.

Changed ``filling.FillingTree.getChildren()`` to introspect extension
classes.

Fixed minor bugs in ``introspect.getCallTip()`` that were interfering
with call tips for Zope/ZODB extension class methods.

In preparation for wxPython 2.3.2, added code to fix a font sizing
problem.  Versions of wxPython prior to 2.3.2 had a sizing bug on Win
platform where the font was 2 points larger than what was specified.

Added a hack to ``introspect.getAllAttributeNames()`` to "wake up"
ZODB objects that are asleep - in a "ghost" state.  Otherwise it
returns incomplete info.


0.6 (8/21/2001 to 9/12/2001)
----------------------------

Added ``PyFilling.py`` and ``filling.py``.

``PyShell.py`` and ``PyFilling.py`` can now be run standalone, as well
as ``PyCrust.py``.

Added ``crust.py`` and moved some code from ``PyCrust.py`` to it.

Added command history retrieval features submitted by Richie Hindle.

Changed ``shell.write()`` to replace line endings with OS-specific
endings.  Changed ``shell.py`` and ``interpreter.py`` to use
``os.linesep`` in strings having hardcoded line endings.

Added ``shell.redirectStdin()``, ``shell.redirectStdout()`` and
``shell.redirectStderr()`` to allow the surrounding app to toggle
requests that the specified ``sys.std*`` be redirected to the shell.
These can also be run from within the shell itself, of course.

The shell now adds the current working directory "." to the search
path::

    sys.path.insert(0, os.curdir)

Added support for distutils installations.


0.5.4 (8/17/2001 to 8/20/2001)
------------------------------

Changed default font size under Linux to::

    'size'   : 12,
    'lnsize' : 10,

Changed ``Shell`` to expect a parameter referencing an Interpreter
class, rather than an intepreter instance, to facilitate subclassing
of Interpreter, which effectively broke when the Editor class was
eliminated.

Fixed ``PyCrustAlaCarte.py``, which had been broken by previous
changes.

Created ``InterpreterAlaCarte`` class as an example for use in the
demo.

Split ``PyCrust.py`` into ``PyCrust.py`` and ``PyShell.py`` in
anticipation of ``PyFilling.py``.


0.5.3 (8/16/2001)
-----------------

Added patch to ``PyCrust.py`` to fix wxPython bug::

    wxID_SELECTALL = NewId() # This *should* be defined by wxPython.


0.5.2 (8/14/2001 to 8/15/2001)
------------------------------

Shortened module names by dropping "PyCrust" as a prefix.

Changed ``version`` to ``VERSION`` in ``version`` module.

Added Options menu to PyCrust application.

Eliminated the Editor class (and editor module) by merging with Shell.
This means that Shell "is a" wxStyledTextCtrl rather than "has a".
There just wasn't enough non-gui code to justify the separation.
Plus, Shell will be much easier for gui toolkits/designers to deal
with now.


0.5.1 (8/10/2001 to 8/14/2001)
------------------------------

Added ``introspect`` module.

Moved some functionality from ``PyCrustInterp`` to ``introspect``.

Changed ``introspect.getRoot()`` to no longer remove whitespace from
the command.  This was a remnant of a previous approach that, when
left as part of the current approach, turned out to be a really bad
thing.

Changed ``introspect.getRoot()`` to allow commands of ``''``, ``""``,
``""""""``, ``[]``, ``()``, and ``{}`` to pass through.  This allows
you to type them, followed by a dot, and get autocomplete options on
them.

Changed ``introspect.getRoot()`` to identify some situations where
strings shouldn't be considered roots.  For example::

    >>> import PyCrust  # To illustrate the potential problem.
    >>> len('PyCrust.py')

Typing the dot at the end of "PyCrust" in the second line above should
NOT result in an autocompletion list because "PyCrust" is part of a
string in this context, not a reference to the PyCrust module object.
Similar reasoning applies to call tips.  For example::

    >>> len('dir(')

Typing the left paren at the end of "dir" should NOT result in a call
tip.

Both features now behave properly in the examples given.  However,
there is still the case where whitespace precedes the potential root
and that is NOT handled properly.  For example::

    >>> len('this is a dir(')

and::

    >>> len('This is PyCrust.py')

More code needs to be written to handle more complex situations.

Added ``locals=None`` parameter to ``Shell.__init__()``.

Added support for magic attribute retrieval.  Users can change this
with::

    >>> shell.editor.autoCompleteIncludeMagic = 0

Added the ability to set filters on auto completion to exclude
attributes prefixed with a single or double underscore.  Users can
exclude one or the other or both with::

    >>> shell.editor.autoCompleteExcludeSingle = 1
    >>> shell.editor.autoCompleteExcludeDouble = 1


0.5 (8/8/2001)
--------------

Mostly just a final version change before creating a release.


0.4 (8/4/2001 to 8/7/2001)
--------------------------

Changed version/revision handling.

Fixed bugs.


0.3 (8/2/2001 to 8/3/2001)
--------------------------

Removed lots of cruft.

Added lots of docstrings.

Imported to CVS repository at SourceForge.

Added call tips.


0.2 (7/30/2001 to 8/2/2001)
---------------------------

Renamed several files.

Added command autocompletion.

Added menus to PyCrust.py: File, Edit and Help.

Added sample applications: ``PyCrustAlaCarte.py``,
``PyCrustAlaMode.py``, and ``PyCrustMinimus.py``.


0.1 (7/1/2001 to 7/19/2001)
---------------------------

Added basic syntax coloring much like Boa.

Added read-only logging much like IDLE.

Can retrieve a previous command by putting the cursor back on that
line and hitting enter.

Stdin and raw_input operate properly so you can now do ``help()`` and
``license()`` without hanging.

Redefined "quit", "exit", and "close" to display a better-than-nothing
response.

Home key honors the prompt.

Created SourceForge account, but nothing was posted.


In the beginning, there was pie... (7/1/2001)
---------------------------------------------

Blame it all on IDLE, Boa and PythonWin.  I was using all three, got
frustrated with their dissimilarities, and began to let everyone know
how I felt.  At the same time, Scintilla looked like an interesting
tool to build a shell around.  And while I didn't receive much in the
way of positive feedback, let alone encouragement, I just couldn't let
go of the idea of a Scintilla-based Python shell.  Then the PythonCard
project got to the point where they were talking about including a
shell in their development environment.  That was all the incentive I
needed.  PyCrust had to happen...
