Description
Summary
An IDE-style native NeoForge editor and inspection toolkit for command blocks and chat commands.
Description
Command Block Studio replaces the vanilla command block screen with a focused command development workspace for map makers, server maintainers and technical creators.
Editor features
- Multiline command editing with stable wrapping and scrolling
- Line numbers, syntax highlighting and exact error navigation
- Brigadier-backed completion from the connected world or server
- Quick documentation for commands, parameters and candidates
- Component, item data-component, particle, block, item, enchantment and player assistance
- Search/replace, command templates, placeholders, undo/redo and bracket matching
- Ordered workspace tabs for individual and chained command block
- Command block item tooltips can show wrapped command text, a second-line shared annotation and available edit metadata.
- A configurable work-mode key, defaulting to
Alt+Tab, displays a command panel with shared annotations in front of the targeted command block; a marked vanilla spyglass works as a handheld scanner. - The editor can save and run-test the current command block once.
- Entering
/in chat opens a compact command assistant with completion, documentation and visual previews. - Long-command spacing, wrapping, cursor placement and overlay layout have been corrected.
Installation
The mod can be installed on the client, server or both:
- Client only: full editor, chat assistant, completion, documentation and local visual tools.
- Server only: vanilla clients can still join normally.
- Both sides: shared comments, ten-entry edit history, rollback, run-test and other negotiated features.
Client and server versions do not need to match exactly. Network-assisted features are enabled independently when both sides expose a compatible interface.
Command Block Studio is built with native NeoForge APIs. It does not depend on Fabric API, Architectury, Sinytra Connector or another loader compatibility layer.
1.1.0 Changelog
Added
- Command excerpts and last-edit metadata for copied command block items.
- Configurable in-world work mode with a command block projection.
- One-click command block run testing.
- Chat command assistant with visual block, item, particle and player candidates.
Fixed
- Long-command spaces no longer collapse visually.
- Wrapped command mouse selection and caret placement now remain aligned.
- Completion and documentation overlays avoid the bottom parameter/status area.
- Vanilla chat completions no longer remain behind the Studio editor, and redundant hover documentation is hidden while the right-hand panel is visible.
- Clicking transient Brigadier completion results no longer crashes, and the multiline chat editor receives keyboard focus immediately.
- Quoted-content replacement no longer overlaps completion ghost text.
- Studio icons no longer render enlarged or cropped on Minecraft 1.21.4 and 26.2.
Networking
- Optional client and server installations remain supported.
- Different client/server mod versions can connect.
- Unsupported shared features are hidden or disabled instead of rejecting the connection.
