Usage

This function is meant to help handle ENR data. Given an input ENR it will output the parsed enode and other values that are part of the payload.

The command below will take an ENR and process it:

echo 'enr:-IS4QHCYrYZbAKWCBRlAy5zzaDZXJBGkcnh4MHcBFZntXNFrdvJjX04jRzjzCBOonrkTfj499SZuOh8R33Ls8RRcy5wBgmlkgnY0gmlwhH8AAAGJc2VjcDI1NmsxoQPKY0yuDUmstAHYpMa2_oxVtw0RW_QAdpzBQA8yWM0xOIN1ZHCCdl8' | \
    polycli enr | jq '.'

This is the output:

{
  "enode": "enode://ca634cae0d49acb401d8a4c6b6fe8c55b70d115bf400769cc1400f3258cd31387574077f301b421bc84df7266c44e9e6d569fc56be00812904767bf5ccd1fc7f@127.0.0.1:0?discport=30303",

  "ip": "127.0.0.1",

}

enr_data="enr:-IS4QHCYrYZbAKWCBRlAy5zzaDZXJBGkcnh4MHcBFZntXNFrdvJjX04jRzjzCBOonrkTfj499SZuOh8R33Ls8RRcy5wBgmlkgnY0gmlwhH8AAAGJc2VjcDI1NmsxoQPKY0yuDUmstAHYpMa2_oxVtw0RW_QAdpzBQA8yWM0xOIN1ZHCCdl8"

# First form - reading from stdin
echo "$enr_data" | polycli enr

# Second form - reading from file
tmp_file="$(mktemp)"
echo "$enr_data" > "$tmp_file" 
polycli enr --file "$tmp_file"
