1// Get live chain data on the URL provided with `forkFrom`, and 
2// insert the necessary data into a chain spec to launch a new chain with.
3// 
4// ### Arguments
5// - `rawSpec`: Path to the raw chain spec to modify
6// - `forkFrom`: URL of the chain's WS port to get the data from
7// 
8// ### Usage
9// `chainql --tla-code=rawSpec="import 'parachain-spec-raw.json'" --tla-str=forkFrom="wss://some-parachain.node:443" fork.jsonnet`
