Build

You need rustc and cargo (default tooling for Rust). Folow the instructions.

If you have Nix installed, you can get all dependencies using nix-shell.

After dependencies are installed, execute the following command.

cargo build

Run

Use the next command to run Zink.

cargo run -- [-f/--file <file to append results to>] jsonpaths

If file is not specified, result is appended to stdout.

Example

Imagine device sending the following data to the Zink:

[
  {"time": 10, "temp": 16, "bat": 28},
  {"bat": 27.9, "temp": 16.25, "time": 11}
]

You can extract it into CSV using the following call.

cargo run -- time,bat,temp

The result is next.

10,28,16
11,27.9,16.25
