Block Grep
by _gid
Block Grep is a client-side utility mod that highlights a chosen block pattern in the world around the player, using shapes, groups and wildcards to define what to find.
What it does
Block Grep marks occurrences of a block pattern near the player. A pattern is built from cells that each match a block, and cells can be combined into larger patterns with explicit dimensions. Patterns can describe one-dimensional, two-dimensional or three-dimensional search shapes, group different blocks together, and use a wildcard. Examples in the author text include a square of four mud or dirt blocks, a grass block stacked over another, and a square of four logs of one wood type.
The mod is configured through a settings screen, opened by assigning a key in the controls menu, or entirely through commands. Fabric Mod Menu lists it when installed. Symmetric shapes are deduplicated, so a symmetric match is reported once even when many orientations are searched. The mod requires Fabric API. Files are published for Fabric and NeoForge, covering 26.1 – 26.3 with five release versions; the latest files are 26.0.1 builds for 26.3 on the beta channel. The code is released under the MIT License and is open source.
Key features
Pattern search
Patterns match cells against blocks, and a wildcard lets one cell accept any block.
Orientation and mirroring
A default pattern matches four compass orientations, and optional symmetry settings allow rotation and mirroring.
Settings screen
A GUI screen creates new patterns and configures how highlights are rendered.
Command configuration
Every setting can also be changed with commands, so the mod can be set up without the screen.
