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

91<h1><a class="toc-backref" href="#id6" 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
93of whimsically-named Python programs and modules that began as the
94PyCrust project. So Py is really several things: a set of standalone
95programs, including the original PyCrust program, a library of Python
96source code modules that can be used in your own programs, and as many
97examples of bad &quot;pie&quot; puns as I can come up with. (If you're going to
98do something, you might as well do it all the way, right?) Py uses
99Python and wxPython, so it works equally well on Windows, Linux and
100Mac OS X.</p>
101</div>
102<div class="section" id="pycrust-is-dead-long-live-py">
103<h1><a class="toc-backref" href="#id7" name="pycrust-is-dead-long-live-py">PyCrust is dead! Long live Py!</a></h1>
104<p>This project began with a program I created called PyCrust - an
105interactive, graphical Python shell, developed using the wxPython GUI
106toolkit. For about two years, PyCrust was hosted on <a class="reference" href="http://www.sf.net/projects/pycrust/">SourceForge</a>.
107Shortly after I created PyCrust, the wxPython folks started including
108it in their distribution. As the PyCrust project grew, it reached a
109point where I thought the original PyCrust name was too confining. I
110was using the PyCrust code base to develop programs that weren't just
111Python shells any more.</p>
112<p>Around that same time, the wxPython folks asked me if I'd be willing
113to move all my wxPython-related projects into the <a class="reference" href="http://cvs.wxWidgets.org">wxPython CVS
114repository</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.
115I decided the time was right to restructure the PyCrust project.
116During the move, the PyCrust package was renamed to &quot;py&quot; (lowercase
117&quot;p&quot;) and the collection of programs and modules as a whole became
118known as &quot;Py&quot; (with a capital &quot;P&quot;).</p>
119<p>The original goal of PyCrust was to be the best interactive, graphical
120Python shell (of course, I claimed it was the &quot;flakiest&quot; Python
121shell). And that was all I wanted it to be. But little by little I
122found myself developing a wider variety of tools for wxPython
123applications. Eventually I'll create a debugger (PySlice, perhaps)
124and whatever else is needed to one day become a complete wxPython
125application development environment (PyFactory?). In the mean time,
126PyCrust is still the flakiest Python shell, and the other Py programs
127are equally tasty.</p>
128<p>At this point, Py has standalone programs that include Python code
129editors (PyAlaCarte and PyAlaMode), interactive Python shells (PyCrust
130and PyShell), and a runtime wrapper (PyWrap). The runtime wrapper
131utility provides you with runtime introspection capabilities for your
132wxPython programs without having to include PyCrust or PyShell in your
133program, and without having to alter one line of your source code.</p>
134<p>Py also contains a collection of modules that you can use in your own
135wxPython applications to provide similar services, either for your own
136use during development, or as an interface for users of your programs.
137These modules are the same ones used by all the Py programs.</p>
138</div>
139<div class="section" id="py-standalone-programs">
140<h1><a class="toc-backref" href="#id8" name="py-standalone-programs">Py standalone programs</a></h1>
141<p>These are the standalone applications in the Py collection:</p>
142<ul class="simple">
143<li>PyAlaCarte</li>
144<li>PyAlaMode</li>
145<li>PyCrust</li>
146<li>PyFilling</li>
147<li>PyShell</li>
148<li>PyWrap</li>

150</div>
151<div class="section" id="pyalacarte">
152<h1><a class="toc-backref" href="#id9" name="pyalacarte">PyAlaCarte</a></h1>
153<p>PyAlaCarte is a Python source code editor. It is designed to have a
154simple, single-file interface. As a standalone application, it is
155good for simple, short editing tasks. But it is really meant to be
156more of an example of how to embed the Py editor into a wxPython
157application.</p>
158</div>
159<div class="section" id="pyalamode">
160<h1><a class="toc-backref" href="#id10" name="pyalamode">PyAlaMode</a></h1>
161<p>PyAlaMode is a Python source code editor.</p>

163<div class="section" id="pycrust">
164<h1><a class="toc-backref" href="#id11" name="pycrust">PyCrust</a></h1>
165<p>PyCrust is an interactive, Python shell. But it's more than just a
166shell. It includes a tabbed notebook containing a namespace tree
167(PyFilling), and several other things.</p>
168</div>
169<div class="section" id="pyfilling">
170<h1><a class="toc-backref" href="#id12" name="pyfilling">PyFilling</a></h1>
171<p>PyFilling is a namespace viewer. It isn't really useful as a
172standalone program, but it does illustrate how to make use of the
173underlying <tt class="docutils literal"><span class="pre">filling</span></tt> module.</p>
174</div>
175<div class="section" id="pyshell">
176<h1><a class="toc-backref" href="#id13" name="pyshell">PyShell</a></h1>
177<p>PyShell is an interactive, Python shell. It shares the same base code
178as PyCrust, but doesn't have any of the extra features that appear in
179the PyCrust notebook interface.</p>
180<div class="figure">

184</div>
185<div class="section" id="pywrap">
186<h1><a class="toc-backref" href="#id14" name="pywrap">PyWrap</a></h1>
187<p>PyWrap is a runtime utility that lets you run an existing wxPython
188program with a PyCrust frame at the same time. Inside the PyCrust
189shell namespace, the local variable <tt class="docutils literal"><span class="pre">app</span></tt> is assigned to your
190application instance. In this way you can introspect your entire
191application within the PyCrust shell, as well as the PyFilling
192namespace viewer.</p>
193</div>
194<div class="section" id="py-modules">
195<h1><a class="toc-backref" href="#id15" name="py-modules">Py modules</a></h1>
196<p>Py was designed to be modular. That means graphical code is kept
197separate from non-graphical code, and many of the Py modules can be
198used by other programs. Likewise, other programs can supply some of
199the modules needed by Py. For example, you could supply a customized
200interpreter module and plug it in to the PyCrust standalone
201application. As long as it supports the minimum functionality
202required, PyCrust will work just as well with your interpreter as with
203its default interpreter.</p>

219<h1><a class="toc-backref" href="#id17" name="history-of-changes">History of changes</a></h1>
220<p>This section lists all the changes that have been made to the Py
221programs and modules, since the beginning.</p>
222<div class="section" id="id1">
223<h2><a class="toc-backref" href="#id18" name="id1">0.9.5 (12/23/2005)</a></h2>
224<p>Applied a series of enhancments by Franz Steinaeusler, Adi Sieker, and
225Sebastian Haase, up until their 7-31-2005 version. (Their next
226version broke some existing functionality, and added some confusing
227hacks, and I didn't feel that the incremental gains were worth the
228loss at that point so I stopped at 7-31-2005.)</p>
229<p>Their changes include the following:</p>
230<ul class="simple">
231<li>The Autocomplete and Calltip windows can now be opened manually with
232Ctrl-Space and Ctrl-Shift-Space.</li>
233<li>In the stand alone PyCrust app the various option settings, window
234size and position, and etc. are saved and restored at the next run.</li>
235<li>Added a help dialog bound to the F1 key that shows the key bindings.</li>
236<li>Added a new text completion function that suggests words from the
237history. Bound to Shift-Return.</li>
238<li>F11 will toggle the maximized state of the frame.</li>
239<li>switched to Bind() from wx.EVT_*().</li>
240<li>Display of line numbers can be toggled.</li>
241<li>F12 toggles a &quot;free edit&quot; mode of the shell buffer. This mode is
242useful, for example, if you would like to remove some output or
243errors or etc. from the buffer before doing a copy/paste. The free
244edit mode is designated by the use of a red, non-flashing caret.</li>
245<li>Ctrl-Shift-F will fold/unfold (hide/show) the selected lines.</li>
246</ul>
247<p>On top of these changes I (Robin Dunn) added the following:</p>
248<ul class="simple">
249<li>General code cleanup and fixes.</li>
250<li>Use wx.StandardPaths to determine the location of the config files.</li>
251<li>Remove Orbtech attributions from the UI, they've been there long
252enough.</li>
253<li>Use wx.SP_LIVE_UPDATE on crust and filling windows.</li>
254<li>Extended the saving of the config info and other new features to the
255PyShell app too. Additionally, other apps that embed a PyCrust or a
256PyShell can pass their own wx.Config object and have the Py code
257save/restore its settings to/from there.</li>
258<li>All of the classes with config info get an opportunity to save/load
259their own settings instead of putting all the save/load code in one
260place that then has to reach all over the place to do anything.</li>
261<li>Enable editing of the startup python code, which will either be the
262file pointed to by PYTHONSTARTUP or a file in the config dir if
263PYTHONSTARTUP is not set in the environment.</li>
264<li>Added an option to skip the running of the startup code when
265PyShell or PyCrust starts.</li>
266<li>PyCrust adds a pp(item) function to the shell's namespace that
267pretty prints the item in the Display tab of the notebook. Added
268code to raise that tab when pp() is called.</li>
269<li>Added an option for whether to insert text for function parameters
270when popping up the call tip.</li>
271<li>Added Find and Find-Next functions that use the wx.FindReplaceDialog.</li>
272</ul>
273</div>
274<div class="section" id="to-2004">
275<h2><a class="toc-backref" href="#id19" name="to-2004">0.9.4 (1/25/2004 to //2004)</a></h2>
276<p>Removed wxd decorators in favor of new SWIG-generated docstrings.</p>
277<p>Removed docs tabs from crust interface:
278* wxPython Docs
279* wxSTC Docs</p>
280<p>Fixed Calltip tab refresh problem on Windows.</p>
281<p>shell.autoCompleteAutoHide added with default of False.</p>
282<p>Changed default namespace of Shell to __main__.__dict__, instead of an
283empty dictionary.</p>

287<p>Fun and games with dynamic renaming. Details of any other changes
288were lost in the confusion. I'll try to do better in the future.</p>

403(Thanks, Kieran Holland.)</p>
404<p>Fixed minor things found by PyChecker.</p>
405<p>Changed locals to use <tt class="docutils literal"><span class="pre">__main__.__dict__</span></tt> and added code to clean up
406the namespace, making it as close to the regular Python environment as
407possible. This solves the problem of pickling and unpickling
408instances of classes defined in the shell.</p>
409<p>Made <tt class="docutils literal"><span class="pre">shell.PasteAndRun()</span></tt> a little more forgiving when it finds a
410ps2 prompt line with no trailing space, such when you copy code from a
411web page.</p>
412<p>Improved autocomplete behavior by adding these to shell:</p>
413<pre class="literal-block">
414self.AutoCompSetAutoHide(False)
415self.AutoCompStops(' .,;:([)]}\'&quot;\\&lt;&gt;%^&amp;+-=*/|`')

418<tt class="docutils literal"><span class="pre">stcConstants.py</span></tt>. These all serve the purpose of adding docstrings
419to existing wxPython classes, in particular the <tt class="docutils literal"><span class="pre">wxStyledTextCtrl</span></tt>.</p>
420<p>Added <tt class="docutils literal"><span class="pre">wrap.py</span></tt>, a command line utility for running a wxPython app
421with additional runtime-tools loaded, such as PyCrust (the only tool
422at this point).</p>
423<p>Flushed the clipboard Cut/Copy operations so that selections will
424exist in the clipboard even after PyCrust has been closed.</p>
425<p>Improved the suppression of docstrings for simple data types appearing
426in the namespace viewer.</p>
427<p>Better handling of autocompletion with numeric types; no
428autocompletion when typing a dot after an integer. If the
429autocompletion is desired, type a space before the dot:</p>
430<pre class="literal-block">
431func = 3 .
432</pre>
433<p>More Filling!!! The namespace tree is now dynamically updated.</p>

437<p>Improved keyboard handling with Autocomplete active. You can now use
438Enter as well as Tab to select an item from the list.</p>
439<p>Disabled autocomplete for lists of 2000 items or more. The current
440implementation of wxSTC can't handle lists this big.</p>
441<p>Changed <tt class="docutils literal"><span class="pre">filling</span></tt> to always display docstrings for objects. This is
442useful for objects whose docstrings have been decorated, rather than
443coming directly from the source code. (Hmmm. Sounds like someone is
444doing some decorating. I wonder where that would be helpful? &lt;wink&gt;)</p>
445<p>Fixed handling of icon. Added <tt class="docutils literal"><span class="pre">images.py</span></tt> file.</p>

453<p>Changed <tt class="docutils literal"><span class="pre">introspect.getRoot()</span></tt> to use <tt class="docutils literal"><span class="pre">tokenize</span></tt> module. This
454does a slightly better job than the previous parsing routine and the
455code is clearer.</p>
456<p>Improved handling of whitespace and empty types during introspection.</p>
457<p>Fixed cut/copy clipboard problem under Linux. (Robin Dunn rocks!!!)</p>
458<p>Added shell.about() which works like this:</p>

486<p>Refactored <tt class="docutils literal"><span class="pre">introspect.py</span></tt> to improve testability.</p>

617<p>Split <tt class="docutils literal"><span class="pre">PyCrust.py</span></tt> into <tt class="docutils literal"><span class="pre">PyCrust.py</span></tt> and <tt class="docutils literal"><span class="pre">PyShell.py</span></tt> in
618anticipation of <tt class="docutils literal"><span class="pre">PyFilling.py</span></tt>.</p>

621<h2><a class="toc-backref" href="#id33" name="id2">0.5.3 (8/16/2001)</a></h2>
622<p>Added patch to <tt class="docutils literal"><span class="pre">PyCrust.py</span></tt> to fix wxPython bug:</p>
623<pre class="literal-block">
624wxID_SELECTALL = NewId() # This *should* be defined by wxPython.
625</pre>
626</div>
627<div class="section" id="to-8-15-2001">
628<h2><a class="toc-backref" href="#id34" name="to-8-15-2001">0.5.2 (8/14/2001 to 8/15/2001)</a></h2>
629<p>Shortened module names by dropping &quot;PyCrust&quot; as a prefix.</p>
630<p>Changed <tt class="docutils literal"><span class="pre">version</span></tt> to <tt class="docutils literal"><span class="pre">VERSION</span></tt> in <tt class="docutils literal"><span class="pre">version</span></tt> module.</p>
631<p>Added Options menu to PyCrust application.</p>
632<p>Eliminated the Editor class (and editor module) by merging with Shell.
633This means that Shell &quot;is a&quot; wxStyledTextCtrl rather than &quot;has a&quot;.
634There just wasn't enough non-gui code to justify the separation.
635Plus, Shell will be much easier for gui toolkits/designers to deal
636with now.</p>
637</div>
638<div class="section" id="to-8-14-2001">
639<h2><a class="toc-backref" href="#id35" name="to-8-14-2001">0.5.1 (8/10/2001 to 8/14/2001)</a></h2>
640<p>Added <tt class="docutils literal"><span class="pre">introspect</span></tt> module.</p>
641<p>Moved some functionality from <tt class="docutils literal"><span class="pre">PyCrustInterp</span></tt> to <tt class="docutils literal"><span class="pre">introspect</span></tt>.</p>
642<p>Changed <tt class="docutils literal"><span class="pre">introspect.getRoot()</span></tt> to no longer remove whitespace from
643the command. This was a remnant of a previous approach that, when
644left as part of the current approach, turned out to be a really bad
645thing.</p>
646<p>Changed <tt class="docutils literal"><span class="pre">introspect.getRoot()</span></tt> to allow commands of <tt class="docutils literal"><span class="pre">''</span></tt>, <tt class="docutils literal"><span class="pre">&quot;&quot;</span></tt>,
647<tt class="docutils literal"><span class="pre">&quot;&quot;&quot;&quot;&quot;&quot;</span></tt>, <tt class="docutils literal"><span class="pre">[]</span></tt>, <tt class="docutils literal"><span class="pre">()</span></tt>, and <tt class="docutils literal"><span class="pre">{}</span></tt> to pass through. This allows
648you to type them, followed by a dot, and get autocomplete options on
649them.</p>
650<p>Changed <tt class="docutils literal"><span class="pre">introspect.getRoot()</span></tt> to identify some situations where
651strings shouldn't be considered roots. For example:</p>
652<pre class="literal-block">
653&gt;&gt;&gt; import PyCrust # To illustrate the potential problem.
654&gt;&gt;&gt; len('PyCrust.py')
655</pre>
656<p>Typing the dot at the end of &quot;PyCrust&quot; in the second line above should
657NOT result in an autocompletion list because &quot;PyCrust&quot; is part of a
658string in this context, not a reference to the PyCrust module object.
659Similar reasoning applies to call tips. For example:</p>
660<pre class="literal-block">
661&gt;&gt;&gt; len('dir(')
662</pre>
663<p>Typing the left paren at the end of &quot;dir&quot; should NOT result in a call
664tip.</p>
665<p>Both features now behave properly in the examples given. However,
666there is still the case where whitespace precedes the potential root
667and that is NOT handled properly. For example:</p>
668<pre class="literal-block">
669&gt;&gt;&gt; len('this is a dir(')
670</pre>
671<p>and:</p>
672<pre class="literal-block">
673&gt;&gt;&gt; len('This is PyCrust.py')
674</pre>
675<p>More code needs to be written to handle more complex situations.</p>
676<p>Added <tt class="docutils literal"><span class="pre">locals=None</span></tt> parameter to <tt class="docutils literal"><span class="pre">Shell.__init__()</span></tt>.</p>
677<p>Added support for magic attribute retrieval. Users can change this
678with:</p>
679<pre class="literal-block">
680&gt;&gt;&gt; shell.editor.autoCompleteIncludeMagic = 0
681</pre>
682<p>Added the ability to set filters on auto completion to exclude
683attributes prefixed with a single or double underscore. Users can
684exclude one or the other or both with:</p>
685<pre class="literal-block">
686&gt;&gt;&gt; shell.editor.autoCompleteExcludeSingle = 1
687&gt;&gt;&gt; shell.editor.autoCompleteExcludeDouble = 1
688</pre>

717<p>Added read-only logging much like IDLE.</p>
718<p>Can retrieve a previous command by putting the cursor back on that
719line and hitting enter.</p>
720<p>Stdin and raw_input operate properly so you can now do <tt class="docutils literal"><span class="pre">help()</span></tt> and
721<tt class="docutils literal"><span class="pre">license()</span></tt> without hanging.</p>
722<p>Redefined &quot;quit&quot;, &quot;exit&quot;, and &quot;close&quot; to display a better-than-nothing
723response.</p>
724<p>Home key honors the prompt.</p>
725<p>Created SourceForge account, but nothing was posted.</p>

729<p>Blame it all on IDLE, Boa and PythonWin. I was using all three, got
730frustrated with their dissimilarities, and began to let everyone know
731how I felt. At the same time, Scintilla looked like an interesting
732tool to build a shell around. And while I didn't receive much in the
733way of positive feedback, let alone encouragement, I just couldn't let
734go of the idea of a Scintilla-based Python shell. Then the PythonCard
735project got to the point where they were talking about including a
736shell in their development environment. That was all the incentive I
737needed. PyCrust had to happen...</p>
