  79 <p>This document will show you how to use the Py programs and the Py
  80 library of Python source code modules.  Py is the new name for the
  81 project that began as PyCrust.  Py is officially part of <a class="reference" href="http://www.wxpython.org/">wxPython</a>,
  82 and includes PyCrust, so PyCrust is no longer distributed separately.</p>

  90 <h1><a class="toc-backref" href="#id5" name="what-is-py">What is Py?</a></h1>
  91 <p>Besides being <a class="reference" href="http://www.wikipedia.org/wiki/Pie">a delicious dessert</a>, Py is the name for a collection
  92 of whimsically-named Python programs and modules that began as the
  93 PyCrust project.  So Py is really several things: a set of standalone
  94 programs, including the original PyCrust program, a library of Python
  95 source code modules that can be used in your own programs, and as many
  96 examples of bad &quot;pie&quot; puns as I can come up with.  (If you're going to
  97 do something, you might as well do it all the way, right?)  Py uses
  98 Python and wxPython, so it works equally well on Windows, Linux and
  99 Mac OS X.</p>
 100 </div>
 101 <div class="section" id="pycrust-is-dead-long-live-py">
 102 <h1><a class="toc-backref" href="#id6" name="pycrust-is-dead-long-live-py">PyCrust is dead! Long live Py!</a></h1>
 103 <p>This project began with a program I created called PyCrust - an
 104 interactive, graphical Python shell, developed using the wxPython GUI
 105 toolkit.  For about two years, PyCrust was hosted on <a class="reference" href="http://www.sf.net/projects/pycrust/">SourceForge</a>.
 106 Shortly after I created PyCrust, the wxPython folks started including
 107 it in their distribution.  As the PyCrust project grew, it reached a
 108 point where I thought the original PyCrust name was too confining.  I
 109 was using the PyCrust code base to develop programs that weren't just
 110 Python shells any more.</p>
 111 <p>Around that same time, the wxPython folks asked me if I'd be willing
 112 to move all my wxPython-related projects into the <a class="reference" href="http://cvs.wxWidgets.org">wxPython CVS
 113 repository</a>, and become part of the <a class="reference" href="http://www.wxpython.org/">wxPython</a>/<a class="reference" href="http://www.wxWidgets.org/">wxWidgets</a> developer team.
 114 I decided the time was right to restructure the PyCrust project.
 115 During the move, the PyCrust package was renamed to &quot;py&quot; (lowercase
 116 &quot;p&quot;) and the collection of programs and modules as a whole became
 117 known as &quot;Py&quot; (with a capital &quot;P&quot;).</p>
 118 <p>The original goal of PyCrust was to be the best interactive, graphical
 119 Python shell (of course, I claimed it was the &quot;flakiest&quot; Python
 120 shell).  And that was all I wanted it to be.  But little by little I
 121 found myself developing a wider variety of tools for wxPython
 122 applications.  Eventually I'll create a debugger (PySlice, perhaps)
 123 and whatever else is needed to one day become a complete wxPython
 124 application development environment (PyFactory?).  In the mean time,
 125 PyCrust is still the flakiest Python shell, and the other Py programs
 126 are equally tasty.</p>
 127 <p>At this point, Py has standalone programs that include Python code
 128 editors (PyAlaCarte and PyAlaMode), interactive Python shells (PyCrust
 129 and PyShell), and a runtime wrapper (PyWrap).  The runtime wrapper
 130 utility provides you with runtime introspection capabilities for your
 131 wxPython programs without having to include PyCrust or PyShell in your
 132 program, and without having to alter one line of your source code.</p>
 133 <p>Py also contains a collection of modules that you can use in your own
 134 wxPython applications to provide similar services, either for your own
 135 use during development, or as an interface for users of your programs.
 136 These modules are the same ones used by all the Py programs.</p>
 137 </div>
 138 <div class="section" id="py-standalone-programs">
 139 <h1><a class="toc-backref" href="#id7" name="py-standalone-programs">Py standalone programs</a></h1>
 140 <p>These are the standalone applications in the Py collection:</p>
 141 <ul class="simple">
 142 <li>PyAlaCarte</li>
 143 <li>PyAlaMode</li>
 144 <li>PyCrust</li>
 145 <li>PyFilling</li>

 150 <div class="section" id="pyalacarte">
 151 <h1><a class="toc-backref" href="#id8" name="pyalacarte">PyAlaCarte</a></h1>
 152 <p>PyAlaCarte is a Python source code editor.  It is designed to have a
 153 simple, single-file interface.  As a standalone application, it is
 154 good for simple, short editing tasks.  But it is really meant to be
 155 more of an example of how to embed the Py editor into a wxPython
 156 application.</p>
 157 </div>
 158 <div class="section" id="pyalamode">

 162 <div class="section" id="pycrust">
 163 <h1><a class="toc-backref" href="#id10" name="pycrust">PyCrust</a></h1>
 164 <p>PyCrust is an interactive, Python shell.  But it's more than just a
 165 shell.  It includes a tabbed notebook containing a namespace tree
 166 (PyFilling), and several other things.</p>
 167 </div>
 168 <div class="section" id="pyfilling">
 169 <h1><a class="toc-backref" href="#id11" name="pyfilling">PyFilling</a></h1>
 170 <p>PyFilling is a namespace viewer.  It isn't really useful as a
 171 standalone program, but it does illustrate how to make use of the
 172 underlying <tt class="literal"><span class="pre">filling</span></tt> module.</p>
 173 </div>
 174 <div class="section" id="pyshell">
 175 <h1><a class="toc-backref" href="#id12" name="pyshell">PyShell</a></h1>
 176 <p>PyShell is an interactive, Python shell.  It shares the same base code
 177 as PyCrust, but doesn't have any of the extra features that appear in
 178 the PyCrust notebook interface.</p>
 179 <div class="figure">

 183 </div>
 184 <div class="section" id="pywrap">
 185 <h1><a class="toc-backref" href="#id13" name="pywrap">PyWrap</a></h1>
 186 <p>PyWrap is a runtime utility that lets you run an existing wxPython
 187 program with a PyCrust frame at the same time.  Inside the PyCrust
 188 shell namespace, the local variable <tt class="literal"><span class="pre">app</span></tt> is assigned to your
 189 application instance.  In this way you can introspect your entire
 190 application within the PyCrust shell, as well as the PyFilling
 191 namespace viewer.</p>
 192 </div>
 193 <div class="section" id="py-modules">
 194 <h1><a class="toc-backref" href="#id14" name="py-modules">Py modules</a></h1>
 195 <p>Py was designed to be modular.  That means graphical code is kept
 196 separate from non-graphical code, and many of the Py modules can be
 197 used by other programs.  Likewise, other programs can supply some of
 198 the modules needed by Py.  For example, you could supply a customized
 199 interpreter module and plug it in to the PyCrust standalone
 200 application.  As long as it supports the minimum functionality
 201 required, PyCrust will work just as well with your interpreter as with
 202 its default interpreter.</p>

 323 </pre>
 324 <p>Continued enhancement of the decorator capability to provide better
 325 documentation and docstrings for wxPython classes and functions.</p>
 326 <p>Introduced new tabbed interface:</p>
 327 <ul class="simple">

 350 (Thanks, Kieran Holland.)</p>
 351 <p>Fixed minor things found by PyChecker.</p>
 352 <p>Changed locals to use <tt class="literal"><span class="pre">__main__.__dict__</span></tt> and added code to clean up
 353 the namespace, making it as close to the regular Python environment as
 354 possible.  This solves the problem of pickling and unpickling
 355 instances of classes defined in the shell.</p>
 356 <p>Made <tt class="literal"><span class="pre">shell.PasteAndRun()</span></tt> a little more forgiving when it finds a
 357 ps2 prompt line with no trailing space, such when you copy code from a

 365 <tt class="literal"><span class="pre">stcConstants.py</span></tt>.  These all serve the purpose of adding docstrings
 366 to existing wxPython classes, in particular the <tt class="literal"><span class="pre">wxStyledTextCtrl</span></tt>.</p>
 367 <p>Added <tt class="literal"><span class="pre">wrap.py</span></tt>, a command line utility for running a wxPython app
 368 with additional runtime-tools loaded, such as PyCrust (the only tool
 369 at this point).</p>
 370 <p>Flushed the clipboard Cut/Copy operations so that selections will
 371 exist in the clipboard even after PyCrust has been closed.</p>
 372 <p>Improved the suppression of docstrings for simple data types appearing
 373 in the namespace viewer.</p>
 374 <p>Better handling of autocompletion with numeric types; no
 375 autocompletion when typing a dot after an integer.  If the
 376 autocompletion is desired, type a space before the dot:</p>
 377 <pre class="literal-block">
 378 func = 3 .
 379 </pre>

 384 <p>Improved keyboard handling with Autocomplete active.  You can now use
 385 Enter as well as Tab to select an item from the list.</p>
 386 <p>Disabled autocomplete for lists of 2000 items or more.  The current
 387 implementation of wxSTC can't handle lists this big.</p>
 388 <p>Changed <tt class="literal"><span class="pre">filling</span></tt> to always display docstrings for objects.  This is
 389 useful for objects whose docstrings have been decorated, rather than
 390 coming directly from the source code.  (Hmmm.  Sounds like someone is
 391 doing some decorating.  I wonder where that would be helpful? &lt;wink&gt;)</p>

 400 <p>Changed <tt class="literal"><span class="pre">introspect.getRoot()</span></tt> to use <tt class="literal"><span class="pre">tokenize</span></tt> module.  This

 402 code is clearer.</p>
 403 <p>Improved handling of whitespace and empty types during introspection.</p>
 404 <p>Fixed cut/copy clipboard problem under Linux.  (Robin Dunn rocks!!!)</p>
 405 <p>Added shell.about() which works like this:</p>

 433 <p>Refactored <tt class="literal"><span class="pre">introspect.py</span></tt> to improve testability.</p>
 434 <p>Improved call tips for unbound methods by leaving the &quot;self&quot;

 605 string in this context, not a reference to the PyCrust module object.
 606 Similar reasoning applies to call tips.  For example:</p>
 607 <pre class="literal-block">
 608 &gt;&gt;&gt; len('dir(')
 609 </pre>
 610 <p>Typing the left paren at the end of &quot;dir&quot; should NOT result in a call
 611 tip.</p>
 612 <p>Both features now behave properly in the examples given.  However,
 613 there is still the case where whitespace precedes the potential root
 614 and that is NOT handled properly.  For example:</p>
 615 <pre class="literal-block">
 616 &gt;&gt;&gt; len('this is a dir(')
 617 </pre>
 618 <p>and:</p>
 619 <pre class="literal-block">
 620 &gt;&gt;&gt; len('This is PyCrust.py')
 621 </pre>
 622 <p>More code needs to be written to handle more complex situations.</p>
 623 <p>Added <tt class="literal"><span class="pre">locals=None</span></tt> parameter to <tt class="literal"><span class="pre">Shell.__init__()</span></tt>.</p>
 624 <p>Added support for magic attribute retrieval.  Users can change this
 625 with:</p>
 626 <pre class="literal-block">
 627 &gt;&gt;&gt; shell.editor.autoCompleteIncludeMagic = 0
 628 </pre>
 629 <p>Added the ability to set filters on auto completion to exclude
 630 attributes prefixed with a single or double underscore.  Users can
 631 exclude one or the other or both with:</p>
 632 <pre class="literal-block">
 633 &gt;&gt;&gt; shell.editor.autoCompleteExcludeSingle = 1
 634 &gt;&gt;&gt; shell.editor.autoCompleteExcludeDouble = 1
 635 </pre>

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