-----------------------------------------
 Changes made to each release of PyCrust
-----------------------------------------


0.9 (2/27/2003 to 3/20/2003)
============================

Added fontIncrease, fontDecrease, fontDefault signals, receivers and
keybindings:

    Ctrl+]            Increase font size.
    Ctrl+[            Decrease font size.
    Ctrl+=            Default font size.

Continued enhancement of the decorator capability to provide better
documentation and docstrings for wxPython classes and functions.

Introduced new tabbed interface:

* Namespace
* Calltip
* Session
* Dispatcher
* wxPython Docs
* wxSTC Docs

Filling.tree now expands tuples as well as lists. (It should have done
this all along, I just never noticed this omission before.)

Added this True/False test to all modules:

    try:
        True
    except NameError:
        True = 1==1
        False = 1==0

Added wxd directory with decoration classes.


0.8.2 (1/5/2003 to 2/26/2003)
=============================

Wrapped sys.ps1, sys.ps2, and sys.ps3 in str(). (Thanks, Kieran
Holland.)

Fixed minor things found by PyChecker.

Changed locals to use __main__.__dict__ and added code to clean up the
namespace, making it as close to the regular Python environment as
possible. This solves the problem of pickling and unpickling instances
of classes defined in the shell.

Made shell.PasteAndRun() a little more forgiving when it finds a ps2
prompt line with no trailing space, such when you copy code from a web
page.

Improved autocomplete behavior by adding these to shell:
    self.AutoCompSetAutoHide(False)
    self.AutoCompStops(' .,;:([)]}\'"\\<>%^&+-=*/|`')

Added decor directory, decorator.py, stcDecor.py, and
stcConstants.py. These all serve the purpose of adding docstrings to
existing wxPython classes, in particular the wxStyledTextControl.

Added wrap.py, a command line utility for running a wxPython app with
additional runtime-tools loaded, such as PyCrust (the only tool at
this point).

Flushed the clipboard Cut/Copy operations so that selections will
exist in the clipboard even after PyCrust has been closed.

Improved the suppression of docstrings for simple data types appearing
in the namespace viewer.

Better handling of autocompletion with numeric types; no
autocompletion when typing a dot after an integer. If the
autocompletion is desired, type a space before the dot:

    func = 3 .

More Filling!!! The namespace tree is now dynamically updated.


0.8.1 (12/20/2002 to 12/25/2002)
================================

Improved keyboard handling with Autocomplete active. You can now use
Enter as well as Tab to select an item from the list.

Disabled autocomplete for lists of 2000 items or more. The current
implementation of wxSTC can't handle lists this big.

Changed filling to always display docstrings for objects. This is
useful for objects whose docstrings have been decorated, rather than
coming directly from the source code. (Hmmm. Sounds like someone is
doing some decorating. I wonder where that would be helpful? ;-)

Fixed handling of icon. Added images.py file.


0.8 (10/29/2002 to 12/16/2002)
==============================

Added "help" to startup banner info.

Made all wx and stc imports explicit. No more import *.

Replaced use of wx's true and false with Python's True and False.

Changed introspect.getRoot() to use tokenize module. This does a
slightly better job than the previous parsing routine and the code is
clearer.

Improved handling of whitespace and empty types during introspection.

Fixed cut/copy clipboard problem under Linux. (Robin Dunn rocks!!!)

Added shell.about() which works like this:

    >>> shell.about()
    PyCrust Version: 0.8
    Shell Revision: 1.80
    Interpreter Revision: 1.15
    Python Version: 2.2.2
    wxPython Version: 2.3.3.1
    Platform: linux2

Added copy plus and paste plus to shell menu.

Moved shell menu from shell.py to shellmenu.py.

Added sys.stdin.readlines() support.

Added time.sleep() in readline() and OnIdle() event handler to free up
the CPU.


0.7.2 (2/22/2002 to 8/27/2002)
==============================

Tweaked getAttributeNames() to pick up a few more attributes:

    '__bases__', '__class__', '__dict__', '__name__', 'func_closure',
    'func_code', 'func_defaults', 'func_dict', 'func_doc',
    'func_globals', 'func_name'

Added a tests directory and unit tests.

Improved support for empty types in the shell: [], () and {} as far as
when call tips and autocompletion are available.

Added support for the other triple string - ''''''.

Refactored introspect.py to improve testability.

Improved call tips for unbound methods by leaving the "self"
parameter, since unbound methods require an instance be passed.

Fixed call tip bug where a tip was displayed when a "(" was typed
after an object that wasn't callable.

Fixed getAllAttributeNames when str(object) fails.

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 point 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 Raul Cota autoCompleteKeys hooks.

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 mult-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 *nix 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.


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...
