When to use regex instead of basic filters

Basic filters only match literal substrings. If the message you want to hide changes each time — different player names, coordinates, or numbers — use regexFilters instead. These entries are Java-style regular expressions, and any console line matching one of them is hidden.

Write and test your pattern

Open the config and find the regexFilters list. Each entry is a regex string in quotes. To hide every "Can't keep up!" line regardless of the numbers after it, use a pattern like .*Can't keep up!.*. The .* on each side means "anything before and after."

Remember that backslashes must be escaped. To match whitespace, write \s in the config, not \s typed once. To match a literal dot, write \..

Common patterns

Hide lines mentioning a specific player: .*PlayerName.*
Hide a whole category by keyword: .*moved too quickly.*
Hide lines starting with a prefix: ^\[Server thread/INFO\].*

Save, restart, and watch the console. If nothing is filtered, your regex likely has an unescaped backslash or a mismatched bracket. Test patterns in a regex tester first, then paste the escaped version into the config.
