gojo

Yet another Go implementation of jo

This is an implementation of jo command written in Go language.

Usage

 $ gojo foo=bar qux=quux
{"foo":"bar","qux":"quux"}
 $ gojo -p foo=bar qux=quux
{
  "foo": "bar",
  "qux": "quux"
}
 $ gojo -a foo bar baz
["foo","bar","baz"]
 $ seq 10 | gojo -a
[1,2,3,4,5,6,7,8,9,10]
 $ gojo -p foo=$(gojo bar=$(gojo baz=100))
{
  "foo": {
    "bar": {
      "baz": 100
    }
  }
}
 $ gojo -p foo[bar][baz][qux][quux]=128
{
  "foo": {
    "bar": {
      "baz": {
        "qux": {
          "quux": 128
        }
      }
    }
  }
}
 $ gojo -p res[foo][][id]=10 res[foo][][id]=20 res[cnt]=2
{
  "res": {
    "foo": [
      {
        "id": 10
      },
      {
        "id": 20
      }
    ],
    "cnt": 2
  }
}
 $ gojo -y res[foo][][id]=10 res[foo][][id]=20 res[cnt]=2
res:
  foo:
    - id: 10
    - id: 20
  cnt: 2
 $ gojo foo=@testdata/file.txt    # read contents from file
{"foo":"a\nb\nc\nd\ne"}
 $ gojo foo=:testdata/file1.json  # json value of file
{"foo":{"x":1,"z":2,"y":3}}
 $ gojo foo=%testdata/file.txt    # base64 of file contents
{"foo":"YQpiCmMKZAplCg=="}

Installation

Homebrew

brew install itchyny/tap/gojo

Build from source

go install github.com/itchyny/gojo/cmd/gojo@latest

Difference to jo

• Implemented in Go and Go-gettable, also useful for library usage.
• Implements nested paths (example: foo[x][y][z]=1, foo[][][]=1).
• Implements YAML output option -y (example: gojo -y foo=1 outputs foo: 1).
• Drops support of k@v syntax (use k=true or k=false) and type guessing flags.
• Does not print duplicate keys (although duplicate key in JSON is valid, it's not that useful and overwritten by the latter).
