RSItemEditor

Edit the item in your hand straight from chat. RSItemEditor is a server-side NeoForge mod that recreates the commands of the popular ItemEdit Spigot plugin for modern Minecraft — rename items, rewrite lore, add enchantments and attributes, tweak dozens of data components, and stash items away for later.

Minecraft: 1.21.1
Loader: NeoForge (21.1+), Kotlin for Forge
Side: server-side (works on a dedicated server or in singleplayer). Clients don't need the mod — everything runs through vanilla-style commands.

Features

/itemedit (/ie) — 30+ sub-commands that edit the held item: name, lore, amount, damage, enchantments, unbreakable, rarity, custom model data, dyed color, armor trim, potion effects, banners, fireworks, written books and more.
/itemstorage (/is) — a private, per-player stash. Save the item in your hand under a name and pull a fresh copy back whenever you want.
/serveritem (/si) — a shared library of items operators can curate and hand out to players.
A permission node per command, so a permission manager (LuckPerms, FTB Ranks, …) can grant access one command at a time.
& color codes everywhere text is accepted, plus WYSIWYG (non-italic) names and lore.
Tab-completion with tooltips — lore-line previews, named colors, online players, stored-item ids and current stack/durability values.
Localized in English, Russian, German, French, Spanish, Chinese and Brazilian Portuguese.

Installing

Install NeoForge 21.1.x for Minecraft 1.21.1.
Install Kotlin for Forge.
Drop rsitemeditor-x.y.z.jar into your server's (or instance's) mods folder.

Commands

Hold an item and run any sub-command. A few highlights:

Command	What it does
`/ie rename <text>`	Set the display name (`&` colors, empty to clear).
`/ie lore add\\|set\\|insert\\|remove\\|clear`	Manage the lore lines.
`/ie enchant <enchant> <level>`	Add, change or remove an enchantment.
`/ie unbreakable [true\\|false]`	Toggle the unbreakable flag.
`/ie amount <n>` / `/ie damage <n>`	Set stack size / durability.
`/ie rarity <rarity>` / `/ie glow`	Cosmetic tweaks.
`/ie color <name\\|#RRGGBB\\|r g b>`	Dye leather / set the color component.
`/ie armortrim <material> <pattern>`	Apply an armor trim.
`/ie type <item>`	Change the item type, keeping its data.
`/ie hide <flag>`	Hide a component (enchants, attributes, …) from the tooltip.
`/ie help`	Clickable, hoverable list of every sub-command.
`/is save\\|get\\|list\\|delete <id>`	Your personal item stash.
`/si save\\|get\\|give\\|list\\|delete <id>`	Shared server items.

Run /ie help in game for the full, self-documenting list.

Permissions

Every command has its own node under the rsitemeditor namespace and defaults to operator level (permission level 2):

rsitemeditor.itemedit.<sub> — e.g. rsitemeditor.itemedit.rename
rsitemeditor.itemstorage.<sub> — save, get, list, delete
rsitemeditor.serveritem.<sub> — save, get, give, list, delete

Grant them individually with your permission mod, or just let operators use everything out of the box.

Where saved items live

Stashed items are stored as NBT inside the world folder:

<world>/rsitemeditor/itemstorage/<player-uuid>.nbt   # personal stashes
<world>/rsitemeditor/serveritems.nbt                 # shared server items

Contributing

Issues and pull requests are welcome. Each command lives in its own file under command/subcommands, so adding a new one is a small, self-contained change — add the file and list it in SubCommands.kt.
