JSON.sh

yo, so it's a json parser written in shell, compatible with ash, bash, dash and zsh

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.

$ 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

a more complex example:

curl registry.npmjs.org/express | ./JSON.sh | egrep '\["versions","[^"]*"\]'
... try it and see

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.

-n

No-head. Don't show nodes that have no path. Normally these output a leading '[]', which you can't use in a bash array.

-s

Remove escaping of the solidus symbol (stright slash).

-h

Show help text.
