Text Editor in C (Univ assignment)

So hey guys :3

I've got this paper that I have to do, and I need to make a text editor. Please assist me and offer tips as I'm currently trying to think this thing through before I get to the actual coding.

•I'm going to be saving everything in a 20x80 matrix, or a string[1601] so I can use every individual character written, is this correct? (I'm declaring the maximum number of chars on screen to 20 lines with 80 columns, fuck anything more, this is a first semester assignment, hence the matric and string lengths)

•How on earth does I shot cursor? I mean, I'm supposed to have the cursor move up and down so the user can write at different parts of his text. Now, I can think of a way to shove the characters of the string "left" or "right" by making an individual proc, but how would one actually go and make the cursor move? Any ideas would be welcome.

•I'm unfamiliar with C extracting anything in .txt format, derp, will google later. Everything we've worked so far is hurrr command prompt calculations.

•In general, any ideas from you experienced coders, feedback, tips, anything, will be bloody welcome. Although I've worked with BYOND and Space Station 13 (/tg/station13) before so I'm familiar with reading Spaghetti code or structured coding using and calling procs() (oh hey I can probably go look at the code there and gather ideas and code formations) I think I'm at a stage where, being confused, I don't even know what QUESTIONS to ask to myself before I start solving the problem.

Just for the record, im studying CS at AUTH university, greece.

this thread sucks.

Aye, got it. Got the C Bible through univ book distribution, I believe it's the same.

also, the lack of that knowledge is only temporary, as it's most probably second semester teaching material.
Due to a lot of students being here through Philosophical schools (as we have them in greece) they haven't worked with programming before, so we have to re-take the entire thing from the start, from a basic indented if to how to include libraries.

If the publisher was deranged enough to rename the K&R to anything involving the word ``Bible'', I'd ditch it and get the real thing. They're dirt-cheap now, you could rob a homeless man and buy the book with his one day's earnings.

I concur gentlemen here. Do a line editor.  We don't need yet another clone of edit.exe.
We need more clones of ed. Don't forget about regexes.

>>46
We need more clones of ed.

ed(1) is already perfect.

ed has too many commands, it needs to be streamlined

#include <stdlib.h>

int main(void)
{
    return system(getenv("EDITOR"));
}

>>47
Ed is a little sucky, actually. If it didn't take four extra characters to type sam -d I wouldn't use ed at all.

Go back to cat-v.org

Keep telling yourself that. DeNile it's not just a large body of water on the north coast of Africa.

Did you seriously just try using L^AT_EX to do [o][u][i][b]^B_BCode's job?

It was a viable SexpCode alternative at one point.
