colors (Linux)

Hi all

Does somebody have a tutorial on colors in c++ (Linux). I searched the forum multiple times, but all i can find are tutorials for win32 :(

Thx in advance

hope this helps

thx
do you have one for C++ or is it threaded the same way?

It works the same in C++, just convert the printf() calls to cout<< calls.

Make sure you read "The Catch" section, then read up on NCURSES.

i converted the printf to cout <<
but now i dont see any colors :(

[color.cpp]

Code:

---

/* Program by Da Boost */
#include <iostream.h>
#include "colors.h"

void Color(int, int, int);
int main()
{
    Color(Bright, Black, White);
    cout << "HELLO WORLD!!!" << endl;
    Color(Reset, White, Black);

    return 0;
}

void Color ( int Attr, int Fgc, int Bgc )$
{
  cout << "0x1B[" << Attr << ";" << Fgc + 30 << ";" << Bgc + 40  << "m";
}

[colors.h]

Code:

---

// colors.h
// This file defines color codes used in Linux
// By Da Boost

// Attributes
#define Reset          0
#define Bright          1
#define Dim            2
#define Underline    3
#define Blink            5
#define Reverse      7
#define Hidden        8

// Colors$
#define Black          0
#define Red            1
#define Green        2
#define Yellow        3
#define Blue            4
#define Magenta    5
#define Cyan          6
#define White          7

[ouput]
0x1B[1;30;47mHELLO WORLD!!!
0x1B[0;37;40m

how can i fix this ?

>> i converted the printf to cout <<
No, you didn't.

C
printf("%s", command);

C++
cout << command;

gg

Uh... That is the character 0x1B, not the string "0x1B".

> cout << "0x1B["
Should be wriiten as

Code:

---

cout << "\x1B["

---

thx all

but isn't there an alternative for the sprintf() ?
what does it do ?

thx in advance

sprintf just writes something to a string. It's for synthesizing strings from fragments of data and constants, etc...

edit: It's quite useful for writing clean output statements.

thx all
