# 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 compatible structures where each value has a bit range, symbolic
|
||
interpretations and know how to be presented in a useful way.
|
||
|
||
You can pronounce the name as you wish, i pronounce jq /‘dʒei’kju:/ so I usually prefer /‘ef’kju:/.
|
||
|
||
**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.
|
||
|
||
## Hopes
|
||
- Make it useful enough that people want to help improve it.
|
||
- Inspire people to create similar tools.
|
||
|
||
## Usage
|
||
|
||
Basic usage is `fq . file`.
|
||
|
||
For details see [usage.md](doc/usage.md)
|
||
|
||
## Install
|
||
|
||
Download [release](https://github.com/wader/fq/releases) for your
|
||
platform, unarchive it and move the executable to `PATH` etc.
|
||
|
||
### Homebrew
|
||
|
||
```sh
|
||
# install latest release
|
||
brew install wader/tap/fq
|
||
```
|
||
|
||
### Arch Linux
|
||
|
||
`fq` can be installed from the [community repository](https://archlinux.org/packages/community/x86_64/fq/) using [pacman](https://wiki.archlinux.org/title/Pacman):
|
||
|
||
```sh
|
||
pacman -S fq
|
||
```
|
||
|
||
You can also build and install the development (VCS) package using an [AUR helper](https://wiki.archlinux.org/index.php/AUR_helpers):
|
||
|
||
```sh
|
||
paru -S fq-git
|
||
```
|
||
|
||
### Nix
|
||
|
||
```sh
|
||
nix-shell -p fq
|
||
```
|
||
|
||
### FreeBSD
|
||
|
||
Use the [fq](https://cgit.freebsd.org/ports/tree/misc/fq) port.
|
||
|
||
### Build from source
|
||
|
||
Make sure you have go 1.17 or later installed.
|
||
|
||
To install directly from git repository do:
|
||
```sh
|
||
# build and install latest release
|
||
go install github.com/wader/fq@latest
|
||
|
||
# or build and install latest master
|
||
go install github.com/wader/fq@master
|
||
|
||
# copy binary to $PATH if needed
|
||
cp "$(go env GOPATH)/bin/fq" /usr/local/bin
|
||
```
|
||
|
||
To build and run tests from source directory:
|
||
```sh
|
||
make test fq
|
||
# copy binary to $PATH if needed
|
||
cp fq /usr/local/bin
|
||
```
|
||
|
||

## Thanks and related projects
|
||
|
||
This project would not have been possible without [itchyny](https://github.com/itchyny)'s
|
||
jq implementation [gojq](https://github.com/itchyny/gojq). I also want to thank
|
||
[HexFiend](https://github.com/HexFiend/HexFiend) for inspiration and ideas and [stedolan](https://github.com/stedolan)
|
||
for inventing the [jq](https://github.com/stedolan/jq) language.
