ANSI escape codes not displaying correctly

Question

I have the following defines:

#define ANSI_COLOR_RED     \"\\e[31m\"
#define ANSI_COLOR_GREEN   \"\\e[32m\"
#define ANSI_COLOR_YELLOW  \"\\e[33m\"
#define ANSI_C         


        

Answer 1

Notice that \e is not a standard escape code and may thus fail (behaviour is undefined!):

% gcc ansi.c -pedantic
ansi.c: In function ‘main’:
ansi.c:4:12: warning: non-ISO-standard escape sequence, '\e'
     printf("\e[1;32mfoobar");

Use \033 or \x1B instead.
