jq

alpine:edge-based dockerization of jq

From the site:

jq is a lightweight and flexible command-line JSON processor. jq is like sed for JSON data - you can use it to slice and filter and map and transform structured data with the same ease that sed, awk, grep and friends let you play with text.

The source code for this image is hosted on GitHub in the backplane/conex repo.

Usage

Interactive

I use a shell function like this to run the image.

jq() {
  run_flags="--rm -i"
  container_flags=""

  if [ -t 0 ]; then
    # stdin is a terminal
    run_flags="${run_flags} -t"
  fi

  if [ -t 1 ] && [ -z "$NOFORMAT" ]; then
    # stdout is a terminal
    container_flags="${container_flags} -C" # colorize json
  else
    # stdout is a pipe or something
    container_flags="${container_flags} -M" # monochrome

    if [ -n "$NOFORMAT" ]; then
      container_flags="${container_flags} -c" # compact
    fi
  fi

  # shellcheck disable=SC2086
  docker run $run_flags "backplane/jq" $container_flags "$@"
}
