Title: Colorizing text in the console
Post by: acerm on November 27, 2019, 01:02:06 pm

Hello! Does anyone know how can I write colored text to the console?

I have a c ++ example that works, but I can't make it work on obj pascal

Code: Pascal  [Select][+][-]

1. #include <iostream>
2.  
3. int main()
4. {
5.     std::cout << "\033[033;31m  red text" << std::endl;
6.     return(0);
7. }

Output:
red text

Obj pascal:

Code: Pascal  [Select][+][-]

1. writeln('\033[033;31m  red text');
2.  

Output:
\033[033;31m  red text

Thanks

Change the C escapes like \033 to proper Pascal writeln syntax using # ?

I've made ansiCRT unit for that purpose. You may take a look at it here (https://gist.github.com/pakLebah/c5e2bbd0b93c863b2122660111db68d1).

Hope it helps. :)
