HexPigeon

Paste a hex dump, describe the layout in JSON or YAML, get a field tree and a highlighted hex view.

The parser is Rust compiled to WASM. The UI is Vue 3.

Layout

parser-wasm/   binary types, endianness, bitflags, strings, CRC
frontend/      schema editor, hex view, parsed tree

Field types: uint8/16/32/64, int8/16/32, float32/64, bitflags8/16, bytes, string_fixed, string_lp8, string_lp16, crc16, crc32, repeated, padding.

Run

Needs wasm-pack, a Rust toolchain with wasm32-unknown-unknown, and Node 22.

nix-shell    # optional
make test
make dev

make dev builds the WASM module, installs frontend deps, and starts Vite on http://localhost:5173.

Schema

{
  "name": "Example Frame",
  "endian": "big",
  "fields": [
    { "name": "magic", "type": "uint8" },
    { "name": "len", "type": "uint8" },
    { "name": "payload", "type": "string_fixed", "length": 5 },
    { "name": "checksum", "type": "crc32", "checksum_range": [0, 11] }
  ]
}

Hex input is whitespace-insensitive. Hovering a field highlights its bytes; CRC fields report valid/invalid when checksum_range is set.
