json.sh

A pipeable JSON parser written in Bash

yo, so it’s a json parser written in bash

Pipe json to it, and it traverses the json objects and prints out the path to the current object (as a JSON array) and then the object, without whitespace.

$ bpkg install -g json.sh

Usage

$ json_parse < package.json
["name"]  "JSON.sh"
["version"]  "0.0.0"
["description"]  ""
["homepage"]  "http://github.com/dominictarr/JSON.sh"
["repository","type"]  "git"
["repository","url"]  "https://github.com/dominictarr/JSON.sh.git"
["repository"]  {"type":"git","url":"https://github.com/dominictarr/JSON.sh.git"}
["bin","json_parse"]  "./JSON.sh"
["bin"]  {"json_parse":"./JSON.sh"}
["dependencies"]  {}
#  ... etc
# Here's a more complex example:
#... try it and see
curl registry.npmjs.org/express | ./JSON.sh | egrep '["versions","[^"]*"]'

Options

  • -b Brief output. Combines ‘Leaf only’ and ‘Prune empty’ options.
  • -l Leaf only. Only show leaf nodes, which stops data duplication.
  • -p Prune empty. Exclude fields with empty values.
  • -h Show help text.
