[PythonCE] PythonCE - I'm a subscriber

[Adam Walley]

Hello, Ihsan.

In general, I find it easier to develop my code on one of my main systems
rather than directly on the mobile device (to transfer and test it on the
device I would then use ftp or a usb cable and activesync).

However, if you want to code and test directly on the mobile device, I
suggest the following steps (this is more of a workaround than a solution,
but it works reasonably well):

- create three plain text files on your device
   >>> f=open("/yourpath/infile.txt","wb")
   >>> f.write("mycode")
   >>> f.close()
   >>> f=open("/yourpath/mycode.txt","wb")
   >>> f.write("# python code\r\n")
   >>> f.close()
   >>> f=open("/yourpath/txt2py.txt","wb")
   >>> f.write("# txt2py renaming utility\r\n")
   >>> f.close()

(note: when in the python interpreter, you can tap a line you have already
typed and press enter/return, and it will appear at the '>>>' prompt so you
can modify it and enter it again - this is quicker than typing the whole
line again)

- now close python and open the 'txt2py.txt' file with the Windows Mobile
text editor (Notes or Word, I think), but remember that when you save the
file you must NOT let Notes change the format. Because it is a text file,
just tapping it should open it in the default editor. Enter the following
python code in the text editor:
   f=open("infile.txt","rb")
   fname=f.read()
   f.close()
   print "opening:",fname+".txt"
   f=open(fname+".txt","rb")
   fdat=f.read()
   f.close()
   print "saving:",fname+".py.py"
   f=open(fname+".py.py","wb")
   f.write(fdat)
   f.close()

Now back in python:
   >>> f=open("/yourpath/txt2py.txt","rb")
   >>> fdat=f.read()
   >>> f.close()
   >>> f=open("/yourpath/txt2py.py.py","wb")
   >>> f.write(fdat)
   >>> f.close()

That's it! Now you can modify the 'mycode.txt' file in your text editor.
When you have saved it you can run the 'txt2py' tool to make a copy of the
file with the '.py.py' extension. Why the double extension? This is just a
simple workaround to make your python files more visible, because Windows
Mobile hides the file extension. By using a simple text file to hold the
root of the filename to convert in 'infile.txt' you can easily modify the
name so 'txt2py' can rename any '.txt' file to a '.py.py' file. Once you
have one text file created, you can create a new text file by doing copy &
paste, then renaming it. Note that the suggestion I am making assumes you
are working with all your files in the same folder.

Of course, once you have it all working, you can work on improving the code.
For example, you could create a 'py2txt' tool.

This is just my suggestion. Others on the list may have better ideas(?).
