Serialize script return value to Cadence json

[sisyphusSmiling]

Issue To Be Solved

It would be really great if script return values could be serialized into Cadence json and saved locally.

Suggest A Solution

A flag added to flow scripts ... like --serialize-to <FILENAME.json>. Say I have a script like:

access(all) fun main(): UInt64 {
  return getCurrentBlock().height
}

That I run with the command:

flow scripts execute ./scripts/get_current_block_height.cdc --serialize-to block-height.json

Where block-height.json looks like

[
  {
    "type": "UInt64",
    "value": "70027781"
  }
]

This would allow me to script the following:

#!/bin/bash

flow scripts execute ./scripts/get_current_block_height.cdc --serialize-to block-height.json
flow transactions execute ./transactions/set_minimum_block_height.cdc --args-json "$(cat block-height.json)"

Where the script result is used as args for the subsequent transaction execution.

Context

Not a blocker, just an idea.
