Light Up (Fabric server-side)

Light Up places light sources automatically around players to brighten caves or surfaces, with per-tick pacing and undo support.

Features

Server-side only (no client mod required)
Command-driven lighting with range, min light, skylight toggle, and type (surface/cave/all)
Per-player undo of the last lighting task
Action-bar style progress (toggle/format configurable)
JSON configuration with live reload
Multi-version builds (1.19.x → 1.21.x)

/lightup reload – reloads config/light-up.json
/lightup cancel – cancels your active lighting task
/lightup undo – undoes your last lighting task
/lightup <block> <min_light_level 0–15> <range> <include_skylight true|false> <lightup_type surface|cave|all> – starts a new lighting task
Alias: /lu

A JSON file is created on first run:
