Hi: http://web.newsguy.com/crcarl/python/hexl.py
This is my first Python program other than tutorial code snippet
experimentation . I chose a hex line editor. I may do a hex screen
editor once this is done, if I feel like playing with the curses module.
Or move straight to wxPython.
This is unfinished, and is really just a hex viewer at this point. It
seems like a good point to stop and see what others think. I would be
interested to hear any comments.
My command parsing if of course crude, brute-force, and not very
scalable. I am doing some reading on this subject, and will be trying
to do a more generalized approach in the next revision. This is going
to be a subject where I need to learn a lot, because I have 2-3
embedded applications in C that need varying levels of command parsers,
so I will be seeking to improve this skill considerably.
Thanks for input.

Looks like mostly clean code to me. I don't understand why you declare
"Offset" globally twice. Wouldn't it make more sense to just stick it
at the top of the file like your "Hexdigits" variable? I'm also not
sure if your style follows the style guide...then again, mine probably
doesn't either. You can check it out here though: http://www.python.org/doc/essays/styleguide.html
Rather than using if/else statements for error checking, you may want
to consider using try/except: http://docs.python.org/tut/node10.html
That my 2¢!

Nowadays the standard for Python style is PEP 8, which represents an
update on the above. http://www.python.org/dev/peps/pep-0008/
Rather than using if/else statements for error checking, you may want
to consider using try/except:
http://docs.python.org/tut/node10.html
That my 2¢!
"if" statements are best if the errors are predictable, "try/except"for
the less predictable ones, or when it would be difficult to ensure
correct program flow with "if".

I started writing this list because I wanted to have definite points
to base a comparison on and as the starting point of writing something
myself. After looking around, I think it would be a waste of time to
start writing yet another IDE and so am now thinking in terms of new
features/plug-ins for existing systems.
Right now I mostly use Komodo Personal and it's pretty close to being
what I want. They don't currently support plug-ins,...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
