If the argument is a string, you can color code your message by prefixing your string with one of these strings:
-
"ERROR": The whole string will be printed in red. Use this prefix to indicate that an error has occurred. -
"SUCCESS": The whole string will be printed in green, similar to the default theme of the Terminal. Use this prefix to indicate that something is correct. -
"WARN": The whole string will be printed in yellow. Use this prefix to indicate that you or a user of your script should be careful of something. -
"INFO": The whole string will be printed in purplish blue. Use this prefix to remind yourself or a user of your script of something. Think of this prefix as indicating an FYI (for your information).
For custom coloring, use ANSI escape sequences. The examples below use the Unicode escape code \u001b. The color coding also works if \u001b is replaced with the hexadecimal escape code \x1b. The Bash escape code \e is not supported. The octal escape code \033 is not allowed because the game runs JavaScript in strict mode.
Example 1
// NS1
// Default color coding.
print("ERROR means something's wrong.");
print("SUCCESS means everything's OK.");
print("WARN Tread with caution!");
print("WARNING, warning, danger, danger!");
print("WARNing! Here be dragons.");
print("INFO for your I's only (FYI).");
print("INFOrmation overload!");
// Custom color coding.
var cyan = "\u001b[36m";
var green = "\u001b[32m";
var red = "\u001b[31m";
var reset = "\u001b[0m";
print(red + "Ugh! What a mess." + reset);
print(green + "Well done!" + reset);
print(cyan + "ERROR Should this be in red?" + reset);
tail();
Example 2
// NS2
// Default color coding.
ns.print("ERROR means something's wrong.");
ns.print("SUCCESS means everything's OK.");
ns.print("WARN Tread with caution!");
ns.print("WARNING, warning, danger, danger!");
ns.print("WARNing! Here be dragons.");
ns.print("INFO for your I's only (FYI).");
ns.print("INFOrmation overload!");
// Custom color coding.
const cyan = "\u001b[36m";
const green = "\u001b[32m";
const red = "\u001b[31m";
const reset = "\u001b[0m";
ns.print(`${red}Ugh! What a mess.${reset}`);
ns.print(`${green}Well done!${reset}`);
ns.print(`${cyan}ERROR Should this be in red?${reset}`);
ns.tail();
