I have been trying to get colour to display with ncurses in fasm for a week, it just seems totally impossible, if anyone can get a box to be coloured or anything with a custom colour pallet or even standard colours can post some code, this has to be format ELF64, i just thinking it is impossible, all that happens is ncurses mostly switches to grey colour which means default colour 0 but sometimes doeasnt, there is a few syscalls can use but i need colour in FASM , can create boxes in ncurses but are all black and white , can create all border types but colour is just impossible, somebody must know how to get it on, i have another post which is clobberd with random attempts. so nobody on here has eveer got colour working with ncurses with format elf64 mode. hope somebody can post some code of ncurses working.

fasm is purely an assembler, it doesn't have any console writing requirements. So I don't understand what you want.

Please describe what happens now, and what you would like to happen instead.

Do you want the STDOUT text from fasm to be coloured in some way?
Do you want the STDERR text from fasm to be coloured in some way?
Do you want your assembled code to output coloured text?
Do you want something else?

You could start with an example of working code that reproduces your problem.

I stated in previous post, but little info just how to get C ncurses colour to work, read

This is how you get colour pairs to work in NASM like:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mov rdx, COLOR_YELLOW
mov rsi, COLOR_BLACK
mov rdi, BLACK_ON_YELLOW
call init_pair
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

# ON FASM JUST NO WAY TO DEFINE THE MACRO LIKE BELOW
#
# COLOR_PAIR(BLACK_ON_YELLOW) <<--(HOW TO GET THIS - ?)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mov esi, COLOR_PAIR(BLACK_ON_YELLOW)
mov edi, [hWindow]
call wattron
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

# BELOW IS THE NASM EQUIVALENT, BASICALLY MY WORKING SCRIPT IS MASSIVE TO UPLOAD, BUT JUST TRYING TO DO ANYTHING TO CHANGE COLOR LIKE WITH :

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mov esi, COLOR_PAIR(BLACK_ON_YELLOW) <<-- (PROBLEM)
mov edi, [hWindow]
call wattron
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

%define COLOR_PAIR(n) ((n) << () <<-- (PROBLEM)

# THE COLOUR PAIR IS A MACRO AND U CANT GET IT WORKING WHAT SO EVER,
I CAN WRITE TO TERMINAL IN COLOUR LIKE WITH ANSI AND ESCAPE SEQUENCES
JUST NEED THE NCURSES TO WORK AND 100% NEED COLOR, I CAN MAKE BOXES AND BORDERS THEM SYSTEM CALLS WORK OK , I JUST NEED THE NCURSES COLOR PALLET
IVE TRUED EVERYTHING THE MACRO IS JUST NOT GONNA WORK , ANY HELP ANYONE HAVE STARTED MOVING MY DATA TO NASM AS I JUST DONT THINK IM EVER GONNA GET COLOUR TO WORK IF ANYONE CAN CHANGE THE TERMINAL BACKGROUND OR COLOUR A BOX THERE IS ONLY A FEW SYSCALLS FOR COLOUR , ANYONE JUST LOOK AT THAT NASM AND SEE IF IT CAN BE DONE ALL IT IS IS THESE NASIC SYSCALLS MAINLY. SOMEBODY
SAID ITS COZ OF INLINE MACROS BUT SURELY WUD BE A WAY TO CHANGE COLOUR, I CANT USE ANSI COMMANDS NEED TO GET 256 COLOURS, I REALLY DONT WANT TO MOVE TO NASM JUST COZ OF COLOR, ?????? CHEERS FOR REPLYING

# SP QUICK REVIEW THESE ARE THE 2 CALLS I NEED TO WORK THEN U REFRESH SCREEN AND NASM TURNS YELLOW, ITS SIMPLE REALLY BUT I JUST DONT KNOW HOW THAT
MACRO WILL WORK IT MUST NEED IT TO CHANGE COLOR BUT U CANT DO SYNTAX LIKE THAT IN FASM ,

And what's the problem here?

NO the problem is how do i get this macro to chamge colour, like nasm these are the commands,

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mov rdx, COLOR_YELLOW
mov rsi, COLOR_BLACK
mov rdi, BLACK_ON_YELLOW
call init_pair
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
mov esi, COLOR_PAIR(BLACK_ON_YELLOW)
mov edi, [hWindow]
call wattron
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

But u cant run this command MACRO in FASM like you do in NASM:

This command specifically ...

mov esi, COLOR_PAIR(BLACK_ON_YELLOW)

U cant run this, problem is if this is needed to change the colour how do i do it in FASM,,

like every other NCURSES linked C syscalls work but color just goes black and white , i do it in NASM and changes straight to yellow, i just haven't seen anyone on FASM forum that has tried to document changing color in NCURSES,

more complex or

Ohh man i just seen what u did then so its just a matter of figuring these macros out, i will try it in bit, just 6am in the UK , i let u know if i can get it to change later, thanks for trying to help tho

much more complex & specific

For anybody reading this about NCURSES COLOR, Found an alternative program NOTCURSES, the color doesnt use init_pair and related color functions like ncurses, I am able to easily define colors ok now in FASM. These terminal TUI based tools are essential when u do hacking stuff, the NOTCURSES seems miles better. I even have full PTY support and also PTY in a PTY . But thanks for anybody that commented.
