RegexRails

A Minecraft Paper plugin that enables smart minecart management through configurable signs and detector rails. Control minecart flow based on their display names using powerful comparison modes and modification options.

Features

• Three operation modes: Compare, Set, and Append
• Multiple comparison options: equals, contains, regex
• Real-time minecart detection and modification
• Redstone-controlled name modifications
• Simple sign-based configuration

Installation

1. Place the plugin jar file in your Spigot (Or any compatible) server's plugin directory
2. Restart the server or run /reload confirm

Usage Guide

Compare Mode

Configure your sign with:

Line 1: Compare
Line 2: equals/contains/regex
Line 3: [comparison value]

The ! sign inverts the output of the comparison. For example, !equals will activate the detector rail when the minecart's name does not match the comparison value.

Example:

Line 1: Compare
Line 2: equals
Line 3: Coal Cart

The detector rail will activate when a minecart named exactly "Coal Cart" passes over it.

Set Mode

Configure your sign with:

Line 1: Set
Line 2: New Name
Line 3: [empty]

Example:

Line 1: Set
Line 2: Iron Ore Cart
Line 3:

Any minecart passing over the detector rail while powered by redstone will have its display name changed to "Iron Ore Cart".

Append Mode

Configure your sign with:

Line 1: Append
Line 2: Text to append
Line 3: [empty]

Example:

Line 1: Append
Line 2: [Full]
Line 3:

Minecarts passing over the detector rail while powered by redstone will have "[Full]" added to their current display name.
