Another approach is to take the convert binary to object part of your code, output that as JSON on stdout and feed that into jq.

Basically, a binary front end + jq = fq

It would be hard to get the full fq functionality that way. How would you encode the data in a way so that you can do both:

    .frames[100].header.sample_rate

for the individual field and

    .frames[100].header|tobytes[:0x10]

for the first few bytes of the entire header structure?

Or decode a binary slice as a particular format:

    tobytes[0x234:0x325]|avc_sps.max_num_ref_frames

I wish this was only the binary front end so I could pick my parser (e.g. PowerShell). I see fq seems to support sending the whole JSON to stdout; I wonder if there's a way to make this the default behavior:

    # JSON for whole file
    fq tovalue file

Hi, i wrote a bit about this in my reply above https://news.ycombinator.com/item?id=29661575

I wrote a small script to convert CSVs to JSON strictly to use jq on the output. Querying things like your GCP bill with jq is quite enjoyable.

gojq is also nice. I work with a lot of structured logs and wrapped jq with a little bit of format-understanding and output sugar to make looking at and analyzing such logs an enjoyable experience: https://github.com/jrockway/json-logs

Note that you can use jq to consume simple CSVs (and produce them) without anything else. There’s an entry in the cookbook wiki https://github.com/stedolan/jq/wiki/Cookbook#convert-a-csv-f... - I posted some usage examples a few months back https://news.ycombinator.com/item?id=27379423

Miller Csv can process json in record format and has a much saner DSL in my experience.
