Placeholders in config.yml

I want to make a placeholder “%prefix%”, and when I change the config and add this placeholder anywhere it will be replaced by the prefix value in the same config.
Configuration:

Prefix: “&7[#00c6ffGym&7]&r”
Messages:

ErrorPlsHelp: “Test %prefix%”.

 

.matcher() and then replace this don't work
@timtower

 

Code:

Code:

private String format(String msg) {
Matcher match2 = prefix.matcher(msg);
while (match2.find()) {
String prefix = msg.substring(match2.start(), match2.end());
msg = msg.replace(prefix, GymPlugin.getInstance().getConfig().getString("prefix") + " ");
}
Matcher match = pattern.matcher(msg);
while (match.find()) {
String color = msg.substring(match.start(), match.end());
msg = msg.replace(color, ChatColor.of(color) + "");
}


return ChatColor.translateAlternateColorCodes('&', msg);
}

Error:

it works, but before that the color class worked.

 

There is no support for hex colors in translateAlternateColorCodes

 

@Kiriller256 There might be a problem with the regex; can you post your patterns and an example message to be processed?
