fq
Tool, language and decoders for inspecting binary data.
In most cases fq works the same way as jq but instead of reading JSON it reads binary data. The result is a JSON compatbile structures where each value knows from which bit ranges it comes from, can have a symbolic interprestation and know how to be presented in useful ways.
NOTE: fq is early in development and many things are missing, broken or do not make sense. That also means there is a great opportunity to help out.
Goals
- Make binary formats accessible and queryable.
- Nested formats and bit-oriented decoding.
- Quick and comfortable CLI tool.
- Bit and byte transformations and conversions.
- Programmer's calculator.
Usage
Basic usage is: fq . file
.
For details see usage.md
Install
Download archive from releases page for your
platform, unarchive it and move the executable to PATH
etc.

Thanks and related projects
This project would not have been possible without itchyny's jq implementation gojq. I also want to thank HexFiend for inspiration and ideas and stedolan for inventing the jq language.
