API

araconf(1)

araconf is a tool for quickly reading values in the closest configuration file. It uses json-select to support JSONPath queries.

Usage

araconf can be used directly from command line. It accepts a single optional JSONPath query and emits valid JSON to stdout.

usage: araconf [-hV] [options] [query]

Options:
  -D, --debug    Enable debug output      [boolean]
  -h, --help     Show help                [boolean]
  -V, --version  Show version number      [boolean]

Examples

Running without a query:

$ araconf
{
  "network": {
    "identity": {}
  },
  "data": {
    "root": "/home/werle/.ara"
  },
  "web3": {
    "provider": "http://127.0.0.1:8545"
  }
}

Targeting the .data object of the conf:

$ araconf .data
{
  "root": "/home/werle/.ara"
}

Targeting the .web3.provider property:

$ araconf .web3.provider
"http://127.0.0.1:8545"

Enable debug output with --debug:

$ araconf .data.root --debug
  ara-runtime-configuration config: /home/werle/.ararc +0ms
  ara-runtime-configuration configs: [ '/home/werle/.ararc' ] +2ms
"/home/werle/.ara"
