C++: why 80 charachters??

[John Doe]

I write code as long as 250+ columns sometimes (when the code refers to
a single concept), and I don't understand why people complain about
that. Just use the word wrap, right?

People who write 80 columns force everybody else in the world to see
their code in a narrow stripe of screen, when almost every programmer
nowdays has 1280x1024+ screen resolution. Many have 1600+!

If the algorithm does not fit into one screen, you are going to make
mistakes when writing or reading it. Losing 2/3 of the screen to stay
into 80 charachters seems nonsense to me.

Re: why 80 charachters??

Maybe such things are called 'portability'.. .
80 columns are quiet enough for me to code. :-)
I would rewrite the code if it exceeds..
Another reason (maybe the major) is to use text-mode screen!! :-)
I prefer to code in text-mode to the graphical mode...

I guess if the result of your editor's word-wrapping algorithm is
acceptable to you, party down. Will that also be the case, though, with
everyone who may ever need to view your code?

For me, to be able to fit more than about 130 characters on my
(1400-pixel-wide) screen would require reducing the font size to something
my 45-year-old eyes would not enjoy trying to read (I get enough headaches
as it is, thank you very much). Not to mention the fact that I may want to
fit another window next to my editor while editing (or at least be able to
see some portion of it)

Bah. If the algorithm doesn't fit on one (modern-length) screen, it's too
complicated (or uses trivial constructs like lots of switch cases).

What about printing? Are you pleased with the results of trying to print
your file with the 250+ columns? I guess you can customize some sort of a
print utility (like the ZLPR program I give away on my site) to do
intelligent things with those long lines, but I think sometime, somewhere,
someone is likely to curse you for them.

Wordwrapped code is unreadable because it wrecks indentation.

Many also use multi-window IDEs, so that the source code window is only a
fraction of the screen.

I find that I can only carefully check code on hardcopy. With a lot of
columns, the hardcopy will be wordwrapped and hence unreadable.

Because some of us are old fashioned and like hard copy? And 12 point
courier is easier to read on standard letter size paper when it's 80
columns?

You can't see all 250 cols at once, right?

Personally, I do not like horizontal scrolling and find that the editor word
wrap feature is pretty weak w/ no customizability (at least in the editor that
I use).

I try to keep it within the general confines of my displayed page, which is
pretty subjective, but usually around a 100-110 cols.

But I bet you never had to pencil in your Hollerith codes onto bubble cards
and wait 4-5 days for them to travel to the computer and back...before you
could begin to fix your /bubbling/ errors ...

Yeah! I did! Back in '75 my Jr. High sent out bubble cards! I wanted
to be '1337, though (OK, so back then we didn't use 1337-sp33k), and I
ran a job that created a bunch of custom $JOB cards, so I didn't have to
waste one bubble card with the $JOB bubble filled in!

Guess I lost the bet ;-)
I think it was 1974 I did it first (Hollywood High School). I rapidly
discovered free keypunch facilities at LACC down the street, and USC's. At
USC's Keck Management school they'd let /anyone/ come in off the street and
hack their VDTs. One day I left a BASIC program running to calculate the
square root of 5 to a few hundred places for a project a math teacher was
doing on Chi, and when I returned (it had been running about four hours by
then), there was a crowd around the screen. I had to shove through with my
pad and paper to get to the front and copy down all the digits /very
carefully/ (I guess they either didn't have printers or I didn't want to
have to slither up to the pick-up window and identify myself as the user of
an account I'd peeked at someone typing the password to...)

I like to stay within 72 columns in case Fortran 77 makes a
comeback and I have to port all of my code.

I can see about 185 chars with Lucida Console size 9, 1600x1200
resolution, Visual Studio; but I can arrive at 250 with size 7 and
Lucida Console is still readable enough. It's just that I'm currently
with a 15" laptop so size 9 is ok.

Lucida console is THE font for programming!!


Seems a bit a strange font at first, but after a couple of days you will
never go back from Lucida Console.

This might be a problem of the word wrapper not being smart enough with
aligning the indentation, but it's not a flaw in my reasoning.

You mean that the reason for which everybody in the world codes in 80
chars is because nobody spent a couple of hours for implementing the
indentation in the word wrappers?

Please don't say that! :-)

Then please try the Lucida Console font for 2 days.
Looks a bit strange at first but after a couple of days you will never
leave that font anymore. It's THE font for programming.

It seems a font for doing OCR: crazily readable after your brain gets
used to it. I guess it can certainly improve your headache. It's
readable up to size 7. I use 9, you can try 10 if you have headaches...
even at size 10 you will definitely go over 130 chars per line even with
side windows

Yeah it's not intended for printing.
But... who prints the programs anymore anyway?
