![fq demo](doc/demo.svg)
fq is inspired by the well known jq tool and language and allows you to work with binary formats the same way you would using jq. In addition it can also present data similar to a hex viewer, transform, slice and concatenate binary data, supports nested formats and has an interactive REPL with auto-completion.

It was originally designed to query, inspect and debug codecs and metadata in media files and containers like mp4, flac, mp3, jpeg. But has since been extended to support a variety of formats like executables, packet captures including TCP reassembly and serialization formats like ASN1 BER, Avro, CBOR, protobuf and a lot more.

In summary it aims to be something like jq, hexdump, dd and gdb combined into one.

**NOTE:** fq is still early in development so things might change, be broken or do not make sense.
That also means that there is a great opportunity to help out!
