About

Description

An addon for Create that adds the Regex Filter: a filter that sorts
items and fluids by their name, in any language, or by the mod that adds them, using a regular expression.

It works everywhere Create accepts a filter: funnels, brass tunnels, deployers, smart chutes, smart fluid pipes,
mechanical arms, stock keeper categories, and more.

Features

  • Match by item name, in any language, regardless of the game's own language.
  • Match by mod ID, e.g. everything from create.
  • Allow or deny matches.
  • Ignore case toggle, on by default.
  • Test slot that shows the exact text being matched and whether an item would pass.
  • Drag items into the test slot from JEI or EMI.
  • Safe on servers: no pattern can freeze the game, however it is written.

Usage

Craft the filter from a book between two brass nuggets. It is also in its own creative tab, Create: Regex
Filter. Right-click it to configure it, then put it in any Create filter slot.

The filter screen

Control What it does
Pattern field The regular expression, up to 32 characters. It turns red when invalid; hover the status text for details.
Aa button Ignore case: upper and lower case letters match each other.
Language box The language item names are read in. Scroll to change it, click to go back to your game language. Empty when matching mod IDs.
Name tag / @ buttons Match the item name or the mod ID.
Allow / deny buttons Let only matching items through, or everything except them.
Test slot Put an item in (click, shift-click, or drag from JEI or EMI) to preview the filter. Not saved.

Matching rules

  • The pattern matches anywhere in the text. Use ^ and $ to match the whole text.
  • Renamed items are matched by their custom name.
  • An invalid pattern lets nothing through, even in deny mode, so a typo never floods a system.
  • The syntax is RE2's: like Java or JavaScript regular expressions,
    without back-references (\1) and lookarounds ((?=...)). Case is set with the Aa button, not (?i).
  • Filters can be copied with Create's filter copying recipe, and cleared by crafting them on their own.

Examples

With Ignore Case on (the default):

Pattern Matches Mode
ingot$ Iron Ingot, Gold Ingot, Brass Ingot, ... Item name
^(iron\|gold)\b Iron Ingot, Iron Sword, Gold Nugget, but not Golden Apple Item name
\bore$ Iron Ore, Deepslate Gold Ore, but not Heavy Core Item name
^create$ Every item from Create Mod ID
^(minecraft\|create)$ + deny Everything not from Minecraft or Create Mod ID

Languages on dedicated servers

In singleplayer every language is available. A dedicated server reads languages from its mods and data packs, so
names from mods (Create included) work in every language they ship.

Minecraft's own item names are the exception: the server only has them in English, so vanilla items fall back to
English names in other languages. To fix this, add a data pack containing assets/minecraft/lang/<code>.json, copied
from a client's .minecraft/assets folder, then run /reload.
