To better appreciate the structure of the document the author is dealing with (and to cast a bit of light on which words are variables in the document and which are `jq` syntax. I offer a shameless plug to a one liner well, I would but the result is "too long for a HN comment" so here a bunch is sniped out of the middle (unedited the result would currently be 140 lines) curl -s https://hn.algolia.com/api/v1/items/27941108 | ~/bin/json2jqpath.jq . .author .children .children|.[] .children|.[]|.author .children|.[]|.children .children|.[]|.children|.[] .children|.[]|.children|.[]|.author .children|.[]|.children|.[]|.children .children|.[]|.children|.[]|.children|.[] .children|.[]|.children|.[]|.children|.[]|.author .children|.[]|.children|.[]|.children|.[]|.children .children|.[]|.children|.[]|.children|.[]|.children|.[] <snip> ... </snip> .children|.[]|.children|.[]|.created_at .children|.[]|.children|.[]|.created_at_i .children|.[]|.children|.[]|.id .children|.[]|.children|.[]|.options .children|.[]|.children|.[]|.parent_id .children|.[]|.children|.[]|.points .children|.[]|.children|.[]|.story_id .children|.[]|.children|.[]|.text .children|.[]|.children|.[]|.title .children|.[]|.children|.[]|.type .children|.[]|.children|.[]|.url .children|.[]|.created_at .children|.[]|.created_at_i .children|.[]|.id .children|.[]|.options .children|.[]|.parent_id .children|.[]|.points .children|.[]|.story_id .children|.[]|.text .children|.[]|.title .children|.[]|.type .children|.[]|.url .created_at .created_at_i .id .options .parent_id .points .story_id .text .title .type .url [0] https://github.com/TomConlin/json_to_paths https://github.com/TomConlin/json_to_paths

Thanks for linking this! I've wanted exactly this script, many times.

Looks a bit like `jq -rc '[path(..)|map(strings//"[]")]|unique[]|"."+join("|.")'`, but might I suggest `jq -rc '[paths|map(("."+strings)//"[]")|join("")]|unique[]'`?

  There is no need to guess, you can just look in the repo. I like the explicit separators when I'm reading them instead of writing them. Helps the individual steps stand out for me. Is there a reason other than a more compact line?
