   If you don't need to digg deep it's also possible to do: $ jq -n '{"a": 1, "b": {"c": 2, "d": 3}, "e": 4} | {a, e}' { "a": 1, "e": 4

   In that case it would be very similar but pick is more general then the shorthand object literal syntax, it can be used with nested index lika .a.b.c or any expression like pick(if .a then .b else .c end) but both has it uses i think.

   Hey, pick is implemented in jq here https://github.com/jqlang/jq/blob/master/src/builtin.jq#L258... using various path functions. When the jq manual say "path expression" like the argument

    Hi author here. Yeap currently only decodes the "wire" format. Actually it can decode using a schema but not parsed from a proto file, this is used by other formats using protobuf as a subformat then they pass a schema internally

    Thanks! i actually experimented a bit with an SQL-like interface for while, dump things into sqlite and use that as query engine. Problem usually was that file formats tend to be mix of array and tree structures more then relational and at

    Hi author here. There is no stable API at the moment and it depends a bit what you want to do. If you mean write own private decoders it is possible but i can't guarantee the API will change, see this old twitter thread https:/&#

    Hi fq author here and also acquaintance with the gnu poke author. One difference is that fq is focused in decoding and querying while poke might be more focused on editing and runtime modeling of formats. But we have both inspired each othe

    Hi author here, i think format mostly but also i thought about fq as file(1) on steroids in the beginning :)

    Hi, i'm working on runtime kaitai support and have made good process but it's quite a big task. Keep an eye on https://github.com/wader/fq/issues/627 your interested.

    Thanks for the kind words! without the other tools i don't think fq would even exist, they inspired and show what was possible.

    fun fact: fq is kind of the spiritual predecessor of https://github.com/wader/flac.tcl , you can see traces of it in flac_frame.go in fq, was used to prototype some things :)

    Hi, sorry for the delay, on vacation. There is no process really more then convincing me :) and i think i will accept any decoder that is for a format used in public, standardized or proprietary. I do want to add some kind of runtime format

    confusingly jq also has a streaming mode https://stedolan.github.io/jq/manual/#Streaming that streams JSON values as [<path>,<value>] pairs. This can also be combined with null input and enables one to

    Hey, i'm the author of fq. It can convert to/from html and JSON (in two different modes). Use -d html, or the fromhtml, fromxml and toxml functions. Ex: $ curl -s https://news.ycombinator.com/ | fq -r -d html &#

    If you want to go deep ISO-14496-12 is probably what your looking for. You can either pay ISO to read it or hypothetically you can google for "filetype:pdf ISO-14496-12". For how things actually work in practice https:/&#x2F

    Hi author of jqjq here. I don't know why Stephen Dolan designed the jq language the way he did. But for me the most attractive things about jq is the terse and pipe-friendly syntax. This allows you to write queries in shells and REPLs

    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) |

    Yes you can! but it's very slow $ ./jqjq "eval($(jq -Rs . jqjq.jq)+.)" <<< '"eval(\"def f: 1,8; [f,f] | map(.+105) | implode\")"' "jqjq" But running jqjq in jq
