# 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.
|
|
|
|

This project would not have been possible without [itchyny](https://github.com/itchyny)'s
|
