fcp

Copy data from/to a farcaster hub

Install

• Binaries: pre-built binaries
• From source: Clone the repo, and run make. Copy the generated binaries fcp and fcp-inspect to a location in your $PATH.
• macOS/Homebrew:

  brew install vrypan/fcp/fcp
  

Use

• fcp --help to see all options.

• Copy fname's casts, reactions and links from your hub to a local file:

  fcp fc://hub.local:3383/fname localfile.data
  

• Upload the local file to your hub:

  fcp localfile.data fc://hub.local:3383
  

(It will fail, because the messages already exist in the hub)

• Use fc+ssl if the hub is using SSL:

  fcp fc+ssl://hub.local:3383/fname localfile.data
  

• Re-sign messages with a new signer before uploading:

  fcp local.data fc+ssl://hub.local:3383/fname --app-key=0x...
  

Examining local files

The files generated by fcp are binary files containing the marshaled protobuf responses from the hub.

• Convert to json:

  fcp-inspect localfile.data
  

• Print out only stats about the file:

  fcp-inspect localfile.data --stats
