wxPython/wx/py/CHANGES.txt

   1 0.9.5 (12/23/2005)
   2 -------------------
   3
   4 Applied a series of enhancments by Franz Steinaeusler, Adi Sieker, and
   5 Sebastian Haase, up until their 7-31-2005 version.  (Their next
   6 version broke some existing functionality, and added some confusing
   7 hacks, and I didn't feel that the incremental gains were worth the
   8 loss at that point so I stopped at 7-31-2005.)
   9
  10 Their changes include the following:
  11
  12 * The Autocomplete and Calltip windows can now be opened manually with
  13   Ctrl-Space and Ctrl-Shift-Space.
  14
  15 * In the stand alone PyCrust app the various option settings, window
  16   size and position, and etc. are saved and restored at the next run.
  17
  18 * Added a help dialog bound to the F1 key that shows the key bindings.
  19
  20 * Added a new text completion function that suggests words from the
  21   history.  Bound to Shift-Return.
  22
  23 * F11 will toggle the maximized state of the frame.
  24
  25 * switched to Bind() from wx.EVT_*().
  26
  27 * Display of line numbers can be toggled.
  28
  29 * F12 toggles a "free edit" mode of the shell buffer.  This mode is
  30   useful, for example, if you would like to remove some output or
  31   errors or etc. from the buffer before doing a copy/paste.  The free
  32   edit mode is designated by the use of a red, non-flashing caret.
  33
  34 * Ctrl-H will fold/unfold (hide/show) the selected lines.
  35
  36
  37
  38 On top of these changes I (Robin Dunn) added the following:
  39
  40 * General code cleanup and fixes.
  41
  42 * Use wx.StandardPaths to determine the location of the config files.
  43
  44 * Remove Orbtech attributions from the UI, they've been there long
  45   enough.
  46
  47 * Use wx.SP_LIVE_UPDATE on crust and filling windows.
  48
  49 * Extended the saving of the config info and other new features to the
  50   PyShell app too.  Additionally, other apps that embed a PyCrust or a
  51   PyShell can pass their own wx.Config object and have the Py code
  52   save/restore its settings to/from there.
  53
  54 * All of the classes with config info get an opportunity to save/load
  55   their own settings instead of putting all the save/load code in one
  56   place that then has to reach all over the place to do anything.
  57
  58 * Enable editing of the startup python code, which will either be the
  59   file pointed to by PYTHONSTARTUP or a file in the config dir if
  60   PYTHONSTARTUP is not set in the environment.
  61
  62 * Added an option to skip the running of the startup code when
  63   PyShell or PyCrust starts.
  64
  65 * PyCrust adds a pp(item) function to the shell's namespace that
  66   pretty prints the item in the Display tab of the notebook.  Added
  67   code to raise that tab when pp() is called.
  68
  69 * Added an option for whether to insert text for function parameters
  70   when popping up the call tip.
  71
  72 * Added Find and Find-Next functions that use the wx.FindReplaceDialog.
  73
  74
  75
  76
  77
  78
  79 0.9.4 (1/25/2004 to //2004)
  80 ------------------------------
  81
  82 Removed wxd decorators in favor of new SWIG-generated docstrings.
  83
  84 Removed docs tabs from crust interface:
  85 * wxPython Docs
  86 * wxSTC Docs
  87
  88 Fixed Calltip tab refresh problem on Windows.
  89
  90 shell.autoCompleteAutoHide added with default of False.
  91
  92 Changed default namespace of Shell to __main__.__dict__, instead of an
  93 empty dictionary.
  94
  95
  96 0.9.3 (9/25/2003 to 1/24/2004)
  97 ------------------------------
  98
  99 Fun and games with dynamic renaming.  Details of any other changes
 100 were lost in the confusion.  I'll try to do better in the future.
 101
 102
 103 0.9.2 (5/3/2003 to 9/25/2003)
 104 -----------------------------
 105
 106 Changed to the new prefix-less "wx" package::
 107
 108     import wx
 109
 110 instead of::
 111
 112     from wxPython import wx
 113
 114 Fixed typo in ``PyWrap.py``::
 115
 116     if __name__ == '__main__':
 117         main(sys.argv)
 118
 119 should have been::
 120
 121     if __name__ == '__main__':
 122         main()
 123
 124 Added pretty-print Display tab to Crust, based on suggestion from
 125 Jason Whitlark.
 126
 127 Improved ``Can*`` checks in ``EditWindow``, since STC is too lenient,
 128 particularly when it is set to read-only but returns True for
 129 CanPaste() (seems like an STC bug to me)::
 130
 131     def CanCopy(self):
 132         """Return True if text is selected and can be copied."""
 133         return self.GetSelectionStart() != self.GetSelectionEnd()
 134
 135     def CanCut(self):
 136         """Return True if text is selected and can be cut."""
 137         return self.CanCopy() and self.CanEdit()
 138
 139     def CanEdit(self):
 140         """Return True if editing should succeed."""
 141         return not self.GetReadOnly()
 142
 143     def CanPaste(self):
 144         """Return True if pasting should succeed."""
 145         return stc.StyledTextCtrl.CanPaste(self) and self.CanEdit()
 146
 147
 148 0.9.1 (3/21/2003 to 5/2/2003)
 149 -----------------------------
 150
 151 PyCrust is dead!  Long live Py!
 152
 153 * Renamed ``PyCrust`` package to ``py``.
 154 * Moved code to wxPython's CVS repository.
 155
 156 Fixed bug in ``introspect.py`` on introspecting objects occurring
 157 immediately after a secondary prompt, like this::
 158
 159     >>> l = [1, 2, 3]
 160     >>> for n in range(3):
 161     ...     l.  <-- failed to popup autocomplete list
 162
 163 Added documentation files:
 164
 165 * PyManual.txt
 166 * wxPythonManual.txt
 167 * wxPythonPackage.txt
 168 * wxPythonExamples.txt
 169
 170 Added PyAlaMode and PyAlaCarte code editors.
 171
 172 Major refactoring to support ``editor`` and ``shell`` from the same
 173 base.
 174
 175 Renamed program files:
 176
 177 * ``PyCrustApp.py`` to ``PyCrust.py``
 178 * ``PyFillingApp.py`` to ``PyFilling.py``
 179 * ``PyShellApp.py`` to ``PyShell.py``
 180 * ``wrap.py`` to ``PyWrap.py``
 181
 182 Removed disabling of autocomplete for lists of 2000 items or more.
 183 The current implementation of wxSTC can now handle lists this big.
 184
 185 Improved handling of ``sys.path`` to mimic the standard Python shell.
 186
 187
 188 0.9 (2/27/2003 to 3/20/2003)
 189 ----------------------------
 190
 191 Added fontIncrease, fontDecrease, fontDefault signals, receivers and
 192 keybindings::
 193
 194     Ctrl+]            Increase font size.
 195     Ctrl+[            Decrease font size.
 196     Ctrl+=            Default font size.
 197
 198 Continued enhancement of the decorator capability to provide better
 199 documentation and docstrings for wxPython classes and functions.
 200
 201 Introduced new tabbed interface:
 202
 203 * Namespace
 204 * Calltip
 205 * Session
 206 * Dispatcher
 207 * wxPython Docs
 208 * wxSTC Docs
 209
 210 ``Filling.tree`` now expands tuples as well as lists.  (It should have
 211 done this all along, I just never noticed this omission before.)
 212
 213 Added this True/False test to all modules::
 214
 215     try:
 216         True
 217     except NameError:
 218         True = 1==1
 219         False = 1==0
 220
 221 Added ``wxd`` directory with decoration classes.
 222
 223
 224 0.8.2 (1/5/2003 to 2/26/2003)
 225 -----------------------------
 226
 227 Wrapped ``sys.ps1``, ``sys.ps2``, and ``sys.ps3`` in ``str()``.
 228 (Thanks, Kieran Holland.)
 229
 230 Fixed minor things found by PyChecker.
 231
 232 Changed locals to use ``__main__.__dict__`` and added code to clean up
 233 the namespace, making it as close to the regular Python environment as
 234 possible.  This solves the problem of pickling and unpickling
 235 instances of classes defined in the shell.
 236
 237 Made ``shell.PasteAndRun()`` a little more forgiving when it finds a
 238 ps2 prompt line with no trailing space, such when you copy code from a
 239 web page.
 240
 241 Improved autocomplete behavior by adding these to shell::
 242
 243     self.AutoCompSetAutoHide(False)
 244     self.AutoCompStops(' .,;:([)]}\'"\\<>%^&+-=*/|`')
 245
 246 Added ``decor`` directory, ``decorator.py``, ``stcDecor.py``, and
 247 ``stcConstants.py``.  These all serve the purpose of adding docstrings
 248 to existing wxPython classes, in particular the ``wxStyledTextCtrl``.
 249
 250 Added ``wrap.py``, a command line utility for running a wxPython app
 251 with additional runtime-tools loaded, such as PyCrust (the only tool
 252 at this point).
 253
 254 Flushed the clipboard Cut/Copy operations so that selections will
 255 exist in the clipboard even after PyCrust has been closed.
 256
 257 Improved the suppression of docstrings for simple data types appearing
 258 in the namespace viewer.
 259
 260 Better handling of autocompletion with numeric types; no
 261 autocompletion when typing a dot after an integer.  If the
 262 autocompletion is desired, type a space before the dot::
 263
 264     func = 3 .
 265
 266 More Filling!!! The namespace tree is now dynamically updated.
 267
 268
 269 0.8.1 (12/20/2002 to 12/25/2002)
 270 --------------------------------
 271
 272 Improved keyboard handling with Autocomplete active.  You can now use
 273 Enter as well as Tab to select an item from the list.
 274
 275 Disabled autocomplete for lists of 2000 items or more.  The current
 276 implementation of wxSTC can't handle lists this big.
 277
 278 Changed ``filling`` to always display docstrings for objects.  This is
 279 useful for objects whose docstrings have been decorated, rather than
 280 coming directly from the source code.  (Hmmm.  Sounds like someone is
 281 doing some decorating.  I wonder where that would be helpful? <wink>)
 282
 283 Fixed handling of icon.  Added ``images.py`` file.
 284
 285
 286 0.8 (10/29/2002 to 12/16/2002)
 287 ------------------------------
 288
 289 Added "help" to startup banner info.
 290
 291 Made all ``wx`` and ``stc`` imports explicit.  No more ``import *``.
 292
 293 Replaced use of the ``wx`` module's ``true`` and ``false`` with
 294 Python's ``True`` and ``False``.
 295
 296 Changed ``introspect.getRoot()`` to use ``tokenize`` module.  This
 297 does a slightly better job than the previous parsing routine and the
 298 code is clearer.
 299
 300 Improved handling of whitespace and empty types during introspection.
 301
 302 Fixed cut/copy clipboard problem under Linux.  (Robin Dunn rocks!!!)
 303
 304 Added shell.about() which works like this::
 305
 306     >>> shell.about()
 307     PyCrust Version: 0.8
 308     Shell Revision: 1.80
 309     Interpreter Revision: 1.15
 310     Python Version: 2.2.2
 311     wxPython Version: 2.3.3.1
 312     Platform: linux2
 313
 314 Added copy plus and paste plus to shell menu.
 315
 316 Moved shell menu from ``shell.py`` to ``shellmenu.py``.
 317
 318 Added ``sys.stdin.readlines()`` support.
 319
 320 Added ``time.sleep()`` in ``readline()`` and ``OnIdle()`` event
 321 handler to free up the CPU.
 322
 323
 324 0.7.2 (2/22/2002 to 8/27/2002)
 325 ------------------------------
 326
 327 Tweaked ``getAttributeNames()`` to pick up a few more attributes::
 328
 329     '__bases__', '__class__', '__dict__', '__name__', 'func_closure',
 330     'func_code', 'func_defaults', 'func_dict', 'func_doc',
 331     'func_globals', 'func_name'
 332
 333 Added a tests directory and unit tests.
 334
 335 Improved support for empty types in the shell: ``[]``, ``()`` and
 336 ``{}`` as far as when call tips and autocompletion are available.
 337
 338 Added support for the other triple string - ``''''''``.
 339
 340 Refactored ``introspect.py`` to improve testability.
 341
 342 Improved call tips for unbound methods by leaving the "self"
 343 parameter, since unbound methods require an instance be passed.
 344
 345 Fixed call tip bug where a tip was displayed when a "(" was typed
 346 after an object that wasn't callable.
 347
 348 Fixed ``getAllAttributeNames`` when ``str(object)`` fails.
 349
 350 Added brace highlighting.  (Thank you, Kevin Altis.)
 351
 352 Fixed problem displaying unicode objects in ``PyFilling``.
 353
 354 Changed how ``filling.py`` checks for expandable objects.  Lists are
 355 now expandable objects.
 356
 357 Made the key handling more robust when there is an active text
 358 selection that includes text prior to the last primary prompt.  Thanks
 359 to Raul Cota for pointing this out.
 360
 361 Fixed wxSTC problem with brace highlighting and non-us keyboards.
 362 (Thank you for the patch, Jean-Michel Fauth.)
 363
 364 Added ``busy = wxBusyCursor()`` to key points in ``shell`` and
 365 ``filling``.
 366
 367 Added ``OnCloseWindow`` handler to ``ShellFrame`` and ``CrustFrame``.
 368
 369 Default to ``SetWrapMode(1)`` for shell and namespace viewer.
 370
 371 Added ``shell.wrap()`` and ``shell.zoom()``.
 372
 373 Added autoCompleteKeys hooks for Raul Cota.
 374
 375 Cleaned up various little key handling bugs.
 376
 377 Changed input methods to get values from shell, rather than dialog
 378 boxes.  Renamed ``readIn`` to ``readline`` and ``readRaw`` to
 379 ``raw_input``.
 380
 381
 382 0.7.1 (12/12/2001 to 2/21/2002)
 383 -------------------------------
 384
 385 Fixed ``OnChar()`` issues effecting European keyboards, as reported by
 386 Jean-Michel Fauth.
 387
 388 Fixed ``introspect.py`` issue with xmlrpc objects reported by Kevin
 389 Altis.
 390
 391 Fixed some introspect/PyFilling issues with regard to Python 2.2.
 392
 393 Fixed font background color as reported by Keith J. Farmer.  (Thanks)
 394
 395 Fixed problem with call tips and autocompletion inside multiline
 396 commands as report by Kevin Altis.
 397
 398 Improved ``OnKeyDown`` handling of cut/copy/paste operations based on
 399 feedback from Syver Enstad.  (Thanks)
 400
 401 Added a ``shell.help()`` method to display some help info.
 402
 403 Changed sort of items in the namespace viewer to case insensitive.
 404
 405 Changed ``attributes.sort(lambda x, y: cmp(x.upper(), y.upper()))`` in
 406 advance of an upcoming fix to an autocompletion matching bug in wxSTC.
 407
 408 Improved support for ZODB by allowing namespace drilldown into BTrees.
 409
 410 Added ``shell.PasteAndRun()`` to support pasting multiple commands into
 411 the shell from the clipboard.  Ctrl+Shift+V or v.
 412
 413 Enter now always processes a command (or copies down a previous one.)
 414 To insert a line break, press Ctrl+Enter.
 415
 416 Escape key clears the current, unexecuted command.
 417
 418 History retrieval changed to replace current command.  Added new keys
 419 to insert from history - Shift+Up and Shift+Down.
 420
 421 Better call tips on objects with ``__call__`` methods.
 422
 423 Improved call tip positioning calculation.
 424
 425
 426 0.7 (10/15/2001 to 12/11/2001)
 427 ------------------------------
 428
 429 Changed how command history retrieval functions work.  Added Alt-P,
 430 Alt-N as keybindings for Retrieve-Previous, Retrieve-Next.
 431
 432 Added full support for multi-line commands, similar to IDLE.
 433
 434 Changed ``introspect.getAttributeNames()`` to do a case insensitive
 435 sort.
 436
 437 Changed Cut/Copy/Paste to deal with prompts intelligently.  Cut and
 438 Copy remove all prompts.  Paste can handle prompted or not-prompted
 439 text.
 440
 441 Added ``CopyWithPrompts()`` method attached to Ctrl-Shift-C for those
 442 times when you really do want all the prompts left intact.
 443
 444 Improved handling of the shell's read-only zone.
 445
 446 Changed ``CrustFrame.__init__`` parameter spec to include all
 447 parameters allowed by a ``wxFrame``.
 448
 449 Changed ``FillingText`` to be read-only.
 450
 451 Renamed ``PyCrust.py`` to ``PyCrustApp.py`` to eliminate
 452 package/module name conflicts that kept you from doing ``from PyCrust
 453 import shell`` inside files located in the ``PyCrust`` directory.
 454
 455 Renamed ``PyFilling.py`` to ``PyFillingApp.py`` and ``PyShell.py`` to
 456 ``PyShellApp.py`` to maintain consistency.
 457
 458 Removed the ``__date__`` property from all modules.
 459
 460 Fixed bug in ``introspect.getCallTip()``, reported by Kevin Altis.
 461
 462
 463 0.6.1 (9/19/2001 to 10/12/2001)
 464 -------------------------------
 465
 466 Changed ``Shell.run()`` to always position to the end of existing
 467 text, as suggested by Raul Cota.
 468
 469 Changed ``introspect.getAllAttributeNames()`` to break circular
 470 references in ``object.__class__``, which occurs in Zope/ZODB
 471 extension classes.
 472
 473 Changed ``filling.FillingTree.getChildren()`` to introspect extension
 474 classes.
 475
 476 Fixed minor bugs in ``introspect.getCallTip()`` that were interfering
 477 with call tips for Zope/ZODB extension class methods.
 478
 479 In preparation for wxPython 2.3.2, added code to fix a font sizing
 480 problem.  Versions of wxPython prior to 2.3.2 had a sizing bug on Win
 481 platform where the font was 2 points larger than what was specified.
 482
 483 Added a hack to ``introspect.getAllAttributeNames()`` to "wake up"
 484 ZODB objects that are asleep - in a "ghost" state.  Otherwise it
 485 returns incomplete info.
 486
 487
 488 0.6 (8/21/2001 to 9/12/2001)
 489 ----------------------------
 490
 491 Added ``PyFilling.py`` and ``filling.py``.
 492
 493 ``PyShell.py`` and ``PyFilling.py`` can now be run standalone, as well
 494 as ``PyCrust.py``.
 495
 496 Added ``crust.py`` and moved some code from ``PyCrust.py`` to it.
 497
 498 Added command history retrieval features submitted by Richie Hindle.
 499
 500 Changed ``shell.write()`` to replace line endings with OS-specific
 501 endings.  Changed ``shell.py`` and ``interpreter.py`` to use
 502 ``os.linesep`` in strings having hardcoded line endings.
 503
 504 Added ``shell.redirectStdin()``, ``shell.redirectStdout()`` and
 505 ``shell.redirectStderr()`` to allow the surrounding app to toggle
 506 requests that the specified ``sys.std*`` be redirected to the shell.
 507 These can also be run from within the shell itself, of course.
 508
 509 The shell now adds the current working directory "." to the search
 510 path::
 511
 512     sys.path.insert(0, os.curdir)
 513
 514 Added support for distutils installations.
 515
 516
 517 0.5.4 (8/17/2001 to 8/20/2001)
 518 ------------------------------
 519
 520 Changed default font size under Linux to::
 521
 522     'size'   : 12,
 523     'lnsize' : 10,
 524
 525 Changed ``Shell`` to expect a parameter referencing an Interpreter
 526 class, rather than an intepreter instance, to facilitate subclassing
 527 of Interpreter, which effectively broke when the Editor class was
 528 eliminated.
 529
 530 Fixed ``PyCrustAlaCarte.py``, which had been broken by previous
 531 changes.
 532
 533 Created ``InterpreterAlaCarte`` class as an example for use in the
 534 demo.
 535
 536 Split ``PyCrust.py`` into ``PyCrust.py`` and ``PyShell.py`` in
 537 anticipation of ``PyFilling.py``.
 538
 539
 540 0.5.3 (8/16/2001)
 541 -----------------
 542
 543 Added patch to ``PyCrust.py`` to fix wxPython bug::
 544
 545     wxID_SELECTALL = NewId() # This *should* be defined by wxPython.
 546
 547
 548 0.5.2 (8/14/2001 to 8/15/2001)
 549 ------------------------------
 550
 551 Shortened module names by dropping "PyCrust" as a prefix.
 552
 553 Changed ``version`` to ``VERSION`` in ``version`` module.
 554
 555 Added Options menu to PyCrust application.
 556
 557 Eliminated the Editor class (and editor module) by merging with Shell.
 558 This means that Shell "is a" wxStyledTextCtrl rather than "has a".
 559 There just wasn't enough non-gui code to justify the separation.
 560 Plus, Shell will be much easier for gui toolkits/designers to deal
 561 with now.
 562
 563
 564 0.5.1 (8/10/2001 to 8/14/2001)
 565 ------------------------------
 566
 567 Added ``introspect`` module.
 568
 569 Moved some functionality from ``PyCrustInterp`` to ``introspect``.
 570
 571 Changed ``introspect.getRoot()`` to no longer remove whitespace from
 572 the command.  This was a remnant of a previous approach that, when
 573 left as part of the current approach, turned out to be a really bad
 574 thing.
 575
 576 Changed ``introspect.getRoot()`` to allow commands of ``''``, ``""``,
 577 ``""""""``, ``[]``, ``()``, and ``{}`` to pass through.  This allows
 578 you to type them, followed by a dot, and get autocomplete options on
 579 them.

 581 Changed ``introspect.getRoot()`` to identify some situations where
 582 strings shouldn't be considered roots.  For example::
 583
 584     >>> import PyCrust  # To illustrate the potential problem.
 585     >>> len('PyCrust.py')
 586
 587 Typing the dot at the end of "PyCrust" in the second line above should
 588 NOT result in an autocompletion list because "PyCrust" is part of a
 589 string in this context, not a reference to the PyCrust module object.
 590 Similar reasoning applies to call tips.  For example::
 591
 592     >>> len('dir(')
 593
 594 Typing the left paren at the end of "dir" should NOT result in a call
 595 tip.
 596
 597 Both features now behave properly in the examples given.  However,
 598 there is still the case where whitespace precedes the potential root
 599 and that is NOT handled properly.  For example::
 600
 601     >>> len('this is a dir(')
 602
 603 and::
 604
 605     >>> len('This is PyCrust.py')
 606
 607 More code needs to be written to handle more complex situations.
 608
 609 Added ``locals=None`` parameter to ``Shell.__init__()``.
 610
 611 Added support for magic attribute retrieval.  Users can change this
 612 with::
 613
 614     >>> shell.editor.autoCompleteIncludeMagic = 0
 615
 616 Added the ability to set filters on auto completion to exclude
 617 attributes prefixed with a single or double underscore.  Users can
 618 exclude one or the other or both with::
 619
 620     >>> shell.editor.autoCompleteExcludeSingle = 1
 621     >>> shell.editor.autoCompleteExcludeDouble = 1

 682
 683
 684 In the beginning, there was pie... (7/1/2001)
 685 ---------------------------------------------
 686
 687 Blame it all on IDLE, Boa and PythonWin.  I was using all three, got
 688 frustrated with their dissimilarities, and began to let everyone know
 689 how I felt.  At the same time, Scintilla looked like an interesting
 690 tool to build a shell around.  And while I didn't receive much in the
 691 way of positive feedback, let alone encouragement, I just couldn't let
 692 go of the idea of a Scintilla-based Python shell.  Then the PythonCard
 693 project got to the point where they were talking about including a
 694 shell in their development environment.  That was all the incentive I
 695 needed.  PyCrust had to happen...
