sde 1.0.3

A CLI tool to edit simple JSON and YAML data files

sde

sde is not sed. It's a structured data editor for CLI.

Why?

Many people asked for a simple JSON in-place editing and jq was the solution:

• Modify a key-value in a json using jq in-place
• How to modify a key's value in a JSON file from command line

jq '.address = "abcde"' test.json|sponge test.json

Does this seem readable or elegant to you?

sde is not a substitue for jq or sed.

It allows simple in-place JSON value changes, for simple data.

{
   "name":"John",
   "age":31,
   "city":"New York",
   "extra": {
       "sex": "male"
   }
}

Modify data

sde name Jack data.json
sde extra.sex female data.json

It is possible to modify data in arrays, e.g.:

{
    "pools": [
        {
            "tls": false, 
            "rig-id": null, 
            "nicehash": false, 
            "url": "pool.hashvault.pro:80", 
            "user": "YOUR_WALLET_ADDRESS", 
            "pass": "x", 
            "enabled": true, 
            "daemon": false, 
            "algo": null, 
            "tls-fingerprint": null, 
            "keepalive": false
        }
    ],
}

Update first pool's pass value to value secret:

sde pools.0.pass secret data.json

Installation for CentOS/RHEL 7, 8 or Amazon Linux 2

sudo yum -y install https://extras.getpagespeed.com/release-latest.rpm
sudo yum -y install sde

Installation for other systems

Installing with pip is easiest:

pip install sde

Notes

Quoting is avoided for null, true, false and numeric values. To ensure that a given value is quoted, use -s (or --string) option:

sde -s key null file.json

If you must edit the file, by ensuring to update only the existing key, use -e (--must-exist) option. The program will exit without adding the key which doesn't exist.

sde -e key val file.json

TODO

Work with stdin

echo $json | sde name Jack

Query simple data

sdg name data.json
