pippy-discuss Mailing List for Pippy: Python for PalmOS

Since pippy doesn't yet have a convenient way to input text, would it be
possible to import pocket c routines, so we can use the pocket c
routines
w pippy ?

Hmm, doubtful that is related to my Load patch.  Most likely its just a mistake
in my build.  That binary has some other experimental changes worked in--
probably something broken there.  When I get a chance I'll put up a less
broken build.

Once they are loaded, they should execute in the current namespace.

So if you define a function foo(), you can call it as foo().  You don't need
to prefix the module's namespace.

Any chance I can compile python programs for Palm on a PC ?

I tried your versions of pippy for the "Load" button which worked, but had 
one problem.  "import string" within my programs don't work. Also, I'm not 
sure what the procedure is for running the programs once they are loaded. 
Can you give some guidance?

Thanks

No, it doesn't use memoimp, but directly loads the files from the memo
db.

> Have you changed anything else from the original Pippy?

I've also added a module "palmwin" for some of the PalmOS window drawing
primitives.  Here are two demos:

http://www.demonseed.net/~jp/pippy/sirpinski.png
http://www.demonseed.net/~jp/pippy/pinwheel.png

If you want to try this out, I have builds at
  http://www.demonseed.net/~jp/pippy/pippy.prc.gz
  http://www.demonseed.net/~jp/pippy/pylib.prc.gz

Next I want to add a handler for raw_input(), so it is easy to do basic
user interaction.  Having trouble figuring out where to put the forms in 
the code though...  I don't want to mess up the separation between 
pylib and pippy.

Jason,

Fabulous! The screen shots look great.  Did you build in the memoimp under 
your "Load" button? Have you changed anything else from the original Pippy?

Thanks!

I'll give Pippy another try then...Dennis

LispMe is pretty good too.

I recently checked changes to Pippy's UI that are similar to LispMe's.

Much easier than using memoimp.

Yes, "Python VM" is the PyLib and "Pippy" is the PyAp. They probably
need=20
to be installed within the same storage media. I mention this because
some=20
applications need their data to be on the same memory card as the=20
application.

"Pocket C" is very nice, easier to work with than Pippy.

Bill,

	I think it is the 2MB memory of the Palm Zire that is giving me
problems, not the installation. When I install pylib.prc, it shows up
as "Python VM", which should be correct right ?

	I'm starting to get tempted to switch to Pocket C if the
stackless
Pippy doesn't arrive soon :(

Rgds,
Dennis

This looks like your Pippy installation is not complete. Did you=20
install "pylib.prc" which comes inside pippy_0_7.zip?  If "pylib.prc" is

installed in the same storage area as you installed "pippy.prc", then I=20
don't know what the problem is and suggest that you remove and reinstall

pippy and the pylib.

Dennis,

Remember that you must create a "Python" MemoPad category and save your 
program in it.  The Pippy importer only looks for memos in the "Python" 
category.

Hello All,

=20

            I just bought my first Palm last night (a Zire) and am
already running Python in interactive mode a few hours later.

=20

            I'm stumped at the point where I would like to run this very
simple python program...

=20

                        #test.py

x, y =3D 0, 0

data_value =3D [1,2,3,4,5,4,3,2,1]

=20

for x in data_value:

                                    print '\n'

                                    for y in range(0,x):

                                                print '*',

=20

            I've typed the following lines in Pippy...based on Kathryn's
response in the sourceforge mailing list.

=20

                        import memoimp; memoimp.install( )

                       =20

                        import test

=20

            Questions :

-          do I need to eval each line ?

-          am I doing this correctly ?

=20

Thanks !

=20

Rgds,

Dennis

Attached is a zip file containing all docs.  Let me know if you have

Jeffery Collins (http://www.boulder.net/~jcollins)

Is there work being done on Pippy?
And where might I find the module docs--am on windows and cannot uncompress 
.tar.gz to read .c files.
Thanks

Your script worked and I am finally able to import from memopad.
Thanks!
Is there Pippy documentation?--describing modules native to palm?
Given this reply, is it possible that some of you are still using Pippy? Is 
there development in the works?
excuse all the questions,
and thanks again, Kathryn

Name a category in memopad Python.
Name all scripts--first memo line--with #myscript.py
import memoimp; memoimp.install()
       5.  You're ready to import from the Memo application.   If you 
named your module
          "mymodule.py" in the memo pad, type the following in the 
interactive interpreter:

        import mymodule
                  6.  To restore the original importer, type
               memoimp.uninstall()

How do we import from the memopad?
What is the exact sequence of commands?

Thanks

Python was ported to the Palm for the purposes of embedding Python in PalmOS
applications, so little attention was paid to the user interface.  There 
are many
obvious shortcomings, such as the ability to create standalone 
applications, GUI
support, etc.. These and others are apparently being addressed by another
developer, but no patches have been submitted.   Since I have very 
little time to
spend developing pippy, I'm hoping that the move to sourceforge will 
stimulate
the interest of developers to contribute to the project.  If you are 
interested, please
visit the site and join the mailing lists there 
(http://lists.sourceforge.net/lists/listinfo/pippy-{devel,discuss}).
