  9. Did someone say let's represent structured data as json? a bit of shameless plug: https://github.com/wader/fq :) It's using a fork of gojq btw!
    comment by wwader · 2023-12-11 · in To a Man with `Jq`, Everything Looks Like JSON
  10. https://github.com/wader/fq has a REPL and can read JSON. Tip is to use "paste | from_json | repl" in a REPl to paste JSON into a sub-REPL, you can also use `<text here>` with fq which is a raw string literal

  11. …JSON and tex (parse using jq functions). I also use it for exploring ane debug binary formats ( https://github.com/wader/fq ). Now a days i also use it for some adhoc programming and a calculator.

  12. I do lots of exploratory work in various structure data, in my case often debugging media filea via https://github.com/wader/fq , which mean doing lots of use-once-queries on the command line or REPL. In those cases jq line-friendly and…

  19. gojq ( https://github.com/itchyny/gojq ) and fq ( https://github.com/wader/fq ) can read YAML and output JSON. But that won't nescessarily help, because other parsers can intepreret that YAML differently.

  21. fq has mp4 support https://github.com/wader/fq is quite visual but is a CLI tool (for now). It has a REPL and query language to poke around. Disclaimer: i'm the author. Other mp4 tools i use are https://gpac.github.io/mp4box.js/test/filerea…

  23. …it can be used for more things with other types then just JSON. If you interested have a look at https://github.com/wader/fq where i've tried to expand on it.

  24. gron is great, i have this in my init.jq file for fq ( https://github.com/wader/fq ). Sadly jq lacks a path_to_expr function so a bit harder to do it with that. def gron: ( path(..) as $p | getpath($p) | scalars | "\($p | path_to_expr) =…

  28. apparently they went ahead and implemented a bunch of them in Go: https://github.com/wader/fq/tree/master/format
    comment by luto · 2021-12-23 · in Fq: Jq for Binary Formats
  29. Supported formats: https://github.com/wader/fq/blob/master/doc/formats.md They should probably make this a bit more prominent. It's an impressive list for a new project.
