.. a "fib".. as in "telling fibs.." 

so the function lies .. therefore it does not return a Fibonacci
sequence..

Like he says it's not written in python.

Well.. I'm also curious why he wants it to be written in python, so I
thought we could join forces.

Incidentally I've been looking for a general-purpose application written
in python/ncurses for some time and haven't found anything.

Looks like no new terminal application was written in the last ten years
or so. I guess that would rule out python..?

Sorry, I'm late with my howmework .. but this is rather cool.

Although .. prefixing all your "system commands" with the far-to-reach
"!" would probably become a royal pain after a while.

Why do you write "most commands" .. what type of command might not be
run by "putting '!' before them?"

In the linux world it would be rather interesting if a distro was
available that uses nothing but python. 

The installer .. the startup scripts .. utilities .. etc.

Maybe there is such a thing and I'm just not aware of it?

Since it would be byt-code being executed it would be faster than
regular shell stuff and a lot easier to customize/maintain.

Don't know enough to figure out if such a thing is possible, though ..

you could use "vim -R" -- or its alter ego "view" ..

"!view neat.py"

I tried that just now under ipython and I end up with the exact same
syntax highlighting that I have when I run vim from the bash prompt.

The problems I am having are mainly due to my bash customization --
aliases, functions .. all that stuff is no longer being recognized ..
and also some bash built-ins such as "cd" do not do anything .. maybe
ipython starts a subprocess that switches and then immediately exits ..
so when I get the prompt back I'm back where I started.

I guess reading the ipython manual and trying to understand what I'm
doing before going any further wouldn't hurt..

Sorry .. couldn't think of a better word .. but by "utilities" I meant
all those shell scripts in /usr/bin that come with gnu/linux distros and
mostly appear to front-end "real" programs.

I guess a python "system shell" could invoke all the C-coded stuff the
same way bash does, no..?  

'nuff [OT] for now..

I'm not sure anyone else mentioned it.  

One additional feature of Vim that you soon will appreciate is that you
get high quality (and timely) support from very knowledgeable users on
the vim@vim.org mailing list.

I am unsure whether simpler editors provide this type of thing.

As to creating one's own color schemes .. there are hundreds that can
be downloaded and installed in a matter of minutes and they're likely
much better than what I would be able to come up with.

Some people are just good at this kind of stuff and I'm not one of 'em.

:-)

So, I tried out the ones that looked nice .. selected a few that I liked
more than the others .. and changed a few things that didn't suit me to
create my own modified versions of the originals. 

Thanks

Not sure where it should go.  

Perhaps add a little nook and cranny link named "facts & advocacy".

I'm only an occasional user of Python and admittedly not as well-read as
many on this list .. but I must say that this is the first time I run
into something that so clearly states what makes Python stand apart from
those other ..  er ..  "difficult" .. should I say ..  languages.

Make it a wiki so everyone can add his two cents?

Start a DocBook, LaTex, CSS.. competition and turn it into some kind of
marketing tool with all the trimmings?

In any event it would be a shame to waste it.
