jq.bash

function jq() {

  FILE=$1; shift
  # Move FILE at the end as expected by native jq
  command jq "$@" "$FILE"

Toy project to autocomplete json file keys in jq.

• Source the above in your shell
• Create a toy json file,
  e.g. echo '{"foo":1,"bar":2,"quz":3}' > toy
• Now you can do autocompletion on keys like this:
  jq toy .<TAB> -> prints autocompletion options: .bar .foo .quz
  jq toy .f<TAB> -> jq toy .foo, ENTER -> print 1

I just modify to also have subkeys as well https://gist.github.com/albertogalan/957a11d15c385c07d0be219a3fbf984c
