"Kaitai Struct: because writing parsers is so much fun, we decided to make it a language! 🎉 Now you too can pretend to enjoy #parsing binary data with just a sprinkle of declarative magic. ✨ With a buffet of languages to choose from, it's like a never-ending cycle of 'which one should I hate today?' 🍽️"

Ah, the "Binary Formats Gallery"—because what the world really needed was a #museum for file formats, complete with GraphViz diagrams and hex dump visualizers! 🤓🖥️ I mean, who doesn't want to spend their Sunday afternoon compiling Kaitai Struct libraries just to admire the metadata of a Quake 2 model? 🌟🔍

#KaitaiStruct, a cross-language binary format parser generator, released a new major version 0.11! Java and Python serialization, partial object tree in the Web IDE, import fixes, `valid/in-enum` to enforce defined enum values, null-terminated UTF-16 strings and much more!

The beauty of #kaitaistruct is that I can reuse the parser from a different language. Today I adapted exactly the same code into a #binaryninja plugin that does all the magic using only a single command.

Recently I discovered that Qt apps have an option to store binary resources as part of the execution binary, this motivated me to create a simple #kaitaistruct parser for it.

Parsing QResource Binary Blobs

This is an interactive demonstration how to parse binary blobs generated by the Qt Resource Compiler (rcc), which are registered within binaries using qRegisterResourceData function. Typically, binary blobs created by rcc comprise three main sections: The `tree` structure outlines the files and directories. Files are tagged with a last_modified timestamp. The `names` section, referenced by the tree nodes, contains binary checksums. The `payload` section includes the size and data of the file. Example: Consi

I used Kaitai Struct to help in my development of python-pickle.rb, a full Ruby implementation of the Python Pickle serialization format (versions 0-5). Although, Kaitai's documentation and example code only explains the structure of the file format, I still had to read the messy Python source code for pickle.py in order to understand how to process certain opcodes. It's still worth checking out if you're writing a file format parser/writer or serializer/deserializer library.

Hello world! Kaitai project and #KaitaiStruct finally got its own its own space in Fediverse!

If you're not familiar with us, we create declarative language for binary format specification — see https://kaitai.io/ — and tooling around it — a compiler which transforms declarative specs into ready-made parsers in variety of programming languages, visualizers and IDE for rapid format spec development and much much more.
