Text Placeholder API

About Placeholder API

It's a small, JIJ-able API that allows creation and parsing placeholders within strings and Minecraft Text Components.
Placeholder API uses a simple format of %modid:type% or %modid:type data% (%modid:type/data% prior to 1.19).
It also includes simple, general usage text format indented for simplifying user input in configs/chats/etc.

For users

It allows users to configure multiple mods in similar way without losing compatibility between mods.
Placeholders allow changing what and where any information is present within compatible mods.

Additionally, Simplified Text Format allows to style them in readable way without the requirement of writing JSON manually or using
generators.

- Default placeholder list
- Mod placeholder list
- QuickText
- Simplified Text Format

Mods generally using this api should just include it directly, but you can downloaded updated version from here if needed!

For developers

Usage of Placeholder API is a simple way to achieve good mod compatibility without having to implement
multiple mod specific apis. Additionally, the placeholder parsing system can be used for replacing
own static (or dynamic placeholders) in Text created by player or read from config. This with combination
of Simplified Text Format allows creating great user/admin experience.

ABOUT THIS LISTING

This page describes Text Placeholder API by Patbox. The description and screenshots are the author's own, imported from their listing on Modrinth on 31 August 2026: https://modrinth.com/mod/placeholder-api

Mythiq.net hosts no files for it. The download button goes straight to the release file on cdn.modrinth.com, so you are downloading from the author's own host, not from a copy of ours.

The download count, rating and comments on this page start at zero and count Mythiq.net only. The source's own figures are not copied here — they measure a different site, and a number that cannot be checked against our own ledger is not worth printing.

MOD LOADER

This release is built for Fabric. A mod built for one loader will not load under another — Fabric mods do not run on Forge, and vice versa.

GAME VERSION

Built for Minecraft 26.2, 26.2-pre-1. Minecraft mods are tied to an exact version: a 1.21.4 build will refuse to load on 1.21.5.

THIS IS A LIBRARY

On its own it adds nothing you can see. It is here because other mods require it, and installing it is usually something another mod asked you to do.

DEPENDENCIES

Check the author's listing for required libraries before you start the game — a missing dependency shows up as a crash on launch, not as a warning.

1. Install Fabric for the Minecraft version you play, if you have not already.

2. Download the .jar with the button on this page. Do not unzip it — a mod jar is installed as it is.

3. Put it in your mods folder:

Windows — %APPDATA%\.minecraft\mods

macOS — ~/Library/Application Support/minecraft/mods

Linux — ~/.minecraft/mods

4. Launch the game with the Fabric profile selected.

ON A SERVER

Anything that changes world generation or gameplay has to be installed on the server as well as on every client. Client-side visual and interface mods do not.

UPDATING

Replace the old .jar rather than adding the new one beside it. Two versions of the same mod in the folder is a crash on launch.
