@hishprorg/vero-optio v2.9.70

@hishprorg/vero-optio

A simple command line Node.js tool to read and write NBT files to JSON and back. Supports big, little and little-varint encoding.

Uses prismarine-nbt for serialization and deserialization, see https://github.com/PrismarineJS/prismarine-nbt for more info on schema.

Usage

via npx:

npx @hishprorg/vero-optio --help

via npm:

npm install -g @hishprorg/vero-optio
@hishprorg/vero-optio --help

usage, feel free to use natural language:
Parse an NBT file to JSON: 
    @hishprorg/vero-optio <path-to-nbt-file> [out-json-file] [little|big|varint]

    @hishprorg/vero-optio level.dat
        (Dump the contents of level.dat to terminal)
    @hishprorg/vero-optio level.dat to level.json
        (Dump the contents of level.dat to JSON)
    @hishprorg/vero-optio level.dat as little to level.json
        (Dump the contents of little endian encoded level.dat to JSON)

Write an JSON file to uncompressed NBT (defaults to big endian):
    @hishprorg/vero-optio write <path-to-json> [out-nbt-file] [little|big|varint]

    @hishprorg/vero-optio write level.json to level.dat
    @hishprorg/vero-optio write level.json to level.dat as little

You can also pipe the input to @hishprorg/vero-optio:
    cat level.dat | @hishprorg/vero-optio
    cat level.dat | @hishprorg/vero-optio to level.json
    cat level.json | @hishprorg/vero-optio write
    cat level.json | @hishprorg/vero-optio write to level.dat

Example

If you do not specify endianness, it will automatically be inferred.

Parse to json, and back to nbt as big endian

$ @hishprorg/vero-optio level.dat level.json
* Dumping NBT file "file.nbt" to "file.json" as JSON
(as big endian)
$ @hishprorg/vero-optio write level.json level.dat
* Writing JSON from "file.json" to "file.nbt" as big endian
written!

Write as little endian

$ @hishprorg/vero-optio level.dat level.json
* Dumping NBT file "file.nbt" to "file.json" as JSON
(as big endian)
$ @hishprorg/vero-optio write level.json level.dat little
* Writing JSON from "file.json" to "file.nbt" as little endian
