Command Block Studio

The editor offers multiline input that wraps and scrolls in a stable layout, with numbered lines, colored syntax and jumps to the exact line of each error. Completion is backed by Brigadier and reads the connected world and server, while search and replace, command templates with placeholders, undo and redo, and bracket matching work inside the window. Ordered workspace tabs hold several command blocks at once, and item tooltips show the wrapped command text.

The mod is aimed at map makers, server maintainers and technical creators who write long chains of commands. Its editor is built with native NeoForge APIs, so no separate loader compatibility layer is required. Installing it works on either side, and neither side needs it, though when both run it their versions must match exactly. Network-assisted features work on each side independently, and both sides must expose a compatible interface.

Files are published for Forge and NeoForge, covering 1.20.4, 1.21.1, 1.21.4 and 26.2, with 1.1.0 as the latest file for each loader. The code is open source under the MIT License, and the project has public links for its source code, issue tracker and wiki.
