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

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

 144 <h1><a class="toc-backref" href="#id7" name="py-standalone-programs">Py standalone programs</a></h1>
 145 <p>These are the standalone applications in the Py collection:</p>
 146 <ul class="simple">

 155 <div class="section" id="pyalacarte">
 156 <h1><a class="toc-backref" href="#id8" name="pyalacarte">PyAlaCarte</a></h1>
 157 <p>PyAlaCarte is a Python source code editor.  It is designed to have a
 158 simple, single-file interface.  As a standalone application, it is
 159 good for simple, short editing tasks.  But it is really meant to be
 160 more of an example of how to embed the Py editor into a wxPython
 161 application.</p>
 162 </div>
 163 <div class="section" id="pyalamode">
 164 <h1><a class="toc-backref" href="#id9" name="pyalamode">PyAlaMode</a></h1>

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

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

 365 <p>Changed locals to use <tt class="literal"><span class="pre">__main__.__dict__</span></tt> and added code to clean up
 366 the namespace, making it as close to the regular Python environment as
 367 possible.  This solves the problem of pickling and unpickling
 368 instances of classes defined in the shell.</p>
 369 <p>Made <tt class="literal"><span class="pre">shell.PasteAndRun()</span></tt> a little more forgiving when it finds a
 370 ps2 prompt line with no trailing space, such when you copy code from a

 379 to existing wxPython classes, in particular the <tt class="literal"><span class="pre">wxStyledTextCtrl</span></tt>.</p>
 380 <p>Added <tt class="literal"><span class="pre">wrap.py</span></tt>, a command line utility for running a wxPython app
 381 with additional runtime-tools loaded, such as PyCrust (the only tool
 382 at this point).</p>
 383 <p>Flushed the clipboard Cut/Copy operations so that selections will
 384 exist in the clipboard even after PyCrust has been closed.</p>
 385 <p>Improved the suppression of docstrings for simple data types appearing
 386 in the namespace viewer.</p>
 387 <p>Better handling of autocompletion with numeric types; no
 388 autocompletion when typing a dot after an integer.  If the
 389 autocompletion is desired, type a space before the dot:</p>
 390 <pre class="literal-block">
 391 func = 3 .

 399 <p>Disabled autocomplete for lists of 2000 items or more.  The current
 400 implementation of wxSTC can't handle lists this big.</p>
 401 <p>Changed <tt class="literal"><span class="pre">filling</span></tt> to always display docstrings for objects.  This is

 416 <p>Improved handling of whitespace and empty types during introspection.</p>
 417 <p>Fixed cut/copy clipboard problem under Linux.  (Robin Dunn rocks!!!)</p>

 607 <tt class="literal"><span class="pre">&quot;&quot;&quot;&quot;&quot;&quot;</span></tt>, <tt class="literal"><span class="pre">[]</span></tt>, <tt class="literal"><span class="pre">()</span></tt>, and <tt class="literal"><span class="pre">{}</span></tt> to pass through.  This allows
 608 you to type them, followed by a dot, and get autocomplete options on
 609 them.</p>
 610 <p>Changed <tt class="literal"><span class="pre">introspect.getRoot()</span></tt> to identify some situations where
 611 strings shouldn't be considered roots.  For example:</p>
 612 <pre class="literal-block">
 613 &gt;&gt;&gt; import PyCrust  # To illustrate the potential problem.
 614 &gt;&gt;&gt; len('PyCrust.py')
 615 </pre>
 616 <p>Typing the dot at the end of &quot;PyCrust&quot; in the second line above should
 617 NOT result in an autocompletion list because &quot;PyCrust&quot; is part of a
 618 string in this context, not a reference to the PyCrust module object.
 619 Similar reasoning applies to call tips.  For example:</p>
 620 <pre class="literal-block">
 621 &gt;&gt;&gt; len('dir(')
 622 </pre>
 623 <p>Typing the left paren at the end of &quot;dir&quot; should NOT result in a call
 624 tip.</p>
 625 <p>Both features now behave properly in the examples given.  However,
 626 there is still the case where whitespace precedes the potential root
 627 and that is NOT handled properly.  For example:</p>
 628 <pre class="literal-block">
 629 &gt;&gt;&gt; len('this is a dir(')
 630 </pre>
 631 <p>and:</p>
 632 <pre class="literal-block">
 633 &gt;&gt;&gt; len('This is PyCrust.py')
 634 </pre>
 635 <p>More code needs to be written to handle more complex situations.</p>
 636 <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>
 637 <p>Added support for magic attribute retrieval.  Users can change this
 638 with:</p>
 639 <pre class="literal-block">
 640 &gt;&gt;&gt; shell.editor.autoCompleteIncludeMagic = 0
 641 </pre>
 642 <p>Added the ability to set filters on auto completion to exclude
 643 attributes prefixed with a single or double underscore.  Users can
 644 exclude one or the other or both with:</p>
 645 <pre class="literal-block">
 646 &gt;&gt;&gt; shell.editor.autoCompleteExcludeSingle = 1
 647 &gt;&gt;&gt; shell.editor.autoCompleteExcludeDouble = 1
 648 </pre>

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