NBT Editor

NOTE: Minecraft 1.20 support will come in a follow up v1.12.1

Main Features:

• 1.17 support
• Display editor: A gui for item names and lore via /itemfactory display. The name, lore, and hideflags item factories have been moved to /itemfactory display <name | lore | hideflags>
• Book editor: A gui for custom written books via /itemfactory book [new]
• Sign editor: A gui for custom signs via /itemfactory signboard [new <type>] (sign is already taken as an alias of signature)
• Importing images (drag onto inventory for item with image lore, drag onto display editor to add to an existent item, drag onto book editor to embed into a page)
• Tooltip overflow fix: Automatically moves and scales tooltips to stay within the screen, useful for viewing lore images (can be disabled in config)
• Find & replace: Multi-line text fields (including the new formatted text fields) support Ctrl+F, including RegEx
• No armor restriction: Allows placing non-armor items into armor slots (must be enabled in the config) - was already possible by editing armor items, but this makes it easier
• Corrupt client chest pages are now backed up with a warning
• /items has been removed in favor of the /open alias

Bug Fixes:

• Fixed incompatibility with the clientcommands mod, causing a crash in some versions of Minecraft
• Fixed command syntax errors showing %s instead of information
• Fixed slots sometimes being referenced incorrectly (eg. space on armor opening a hotbar slot) in older Minecraft versions
• Fixed the offhand slot being referenced incorrectly
• Fixed /itemfactory display lore list, then clicking on a line, showing JSON instead of the currently configured text mode
• Fixed the text format system not allowing multiple formats at the same time (eg. bold and italic)
• Fixed item tooltips appearing underneath the page text field and logo in the client chest
• Fixed crash when hitting enter in a string input field if the input is invalid
• Fixed bottom right slot of a container being uneditable in some scenarios
• Fixed the save indication not waiting for a parent save to finish (eg. a sub-container within the client chest should wait for the client chest page to finish saving)
• Fixed client chest save errors not showing an error in chat
• Fixed closing the client chest or container view right after moving something into your inventory creating a ghost item
• Fixed deleting characters in multi-line text fields not adding an undo entry, so you couldn't Ctrl+Z just that edit
• Fixed a warning in the console about CommandExecutionC2SPacketMixin when launching in older versions
• Fixed the bridge library being loaded when launching the game causing a crash, making the mod incompatible with the feather launcher
• Fixed expanding an opened string causing the string to be replaced with the non-string version (eg. NbtString '{"text":"test"}' => NbtCompound {"text":"test"})
• Fixed crash when editing the display.Name tag if the name field at the top of the screen was scrolled over more than the new name length
• Fixed text fields being edited from the bottom of the screen up causing the lower ones to appear focused in some guis
• Fixed text field selection highlights not appearing on the text field in some guis
• Fixed the cursor in some text fields not blinking

Noteworthy Code Base Changes (for API users):

• ItemReference has been refactored, which allows you to create custom ItemReference types (meaning some enderchest mod could allow editing enderchest items directly for example)
• ClientContainerScreen is now called ClientHandledScreen
• the screens package has been sorted into sub-packages
