fario

Farcaster command-line tools.

Warning: These scripts have not been tested extensively. Use them at your own risk!

Installation

Using Homebrew (macOS)

fario is still a "tap" (a third-party repository). This means that installing it will compile everything and it will take some time, depending on your computer.

That said, you can try:

• brew tap vrypan/fario to configure the tap.
• brew install fario to install.

Using pip (python)

pip install fario

(Any help packaging these scripts as a brew recipe, apt package, etc., will be appreciated!)

Commands: fario-out, fario-in, fario-signers, fario-cast, fario-config, fario2json, json2fario, fario-id-byname, fario-account.

Most of these command will require you to have access to a Farcaster hub: How to get access to a hub.

After installing

Most of the commands need a number of parameters (such as keys, fids, endpoints, etc.) and typing them again and agian is taxing. Run fario-config make to create a configuration. Save it to ~/.fario and add the values you don't want to type every time.

Teaser

fario has become quite powerful. Using with other cli tools available on a unix system, you can do things like this just using your terminal and a farcaster hub.

Data format

Most of the scripts bellow pipe farcaster Message objects in and/or out. To make the payload command-line friendly, we serialize it and encode it using base64. So where "far data" is mentioned bellow, this is a protobuf Message converted like this: base64(serialize(Message)).

fario-out

fario-out is used to export data from a farcaster hub.

usage: fario-out [-h] [--version] [--casts] [--links] [--recasts] [--likes] [--inlinks] [--profile] [--all] [--limit LIMIT] [--hub HUB] [--wait WAIT] fid

Export Farcaster data.

positional arguments:
  fid            Export messages from fid=FID

options:
  -h, --help     show this help message and exit
  --version      show program's version number and exit
  --casts        User casts
  --links        User links
  --recasts      User recasts
  --likes        User likes
  --inlinks      Inbound links for user
  --profile      User profile data
  --all          Equivalent to --casts --links --recasts --likes --profile
  --limit LIMIT  Number of records. If more than one types of data are exported, the limit applies to each one separately.
  --hub HUB      Use the hub at <HUB>. Ex. --hub 192.168.1.1:2283
  --wait WAIT    Wait for <WAIT> milliseconds between reads.

Example:

fario-out --casts --limit=3 280

The result is 3 lines of text. Each line is the corresponding farcaster message serialized and base64 encoded.

It is easy to decode a message using fario2json.

Try: fario-out --all --limit=5 2 | fario2json | jq

fario-in

fario-in is used to post data (messages) to a farcaster hub. Input is read from stdin and it is expected to be base64 encoded serialized protobuf messages, like the ones exported by fario-out.

fario-in --help

usage: fario-in [-h] [--version] [--hub HUB] [--wait WAIT]

Send messages to Farcaster hub.

options:
  -h, --help   show this help message and exit
  --version    show program's version number and exit
  --hub HUB    Use the hub at <HUB>. Ex. --hub 192.168.1.1:2283
  --wait WAIT  Wait for <WAIT> milliseconds between message submissions.

fario-signers

Add, remove, list signers and sign farcaster messages.

fario-signers --help

usage: fario-signers [-h] [--version] [--raw] {add,remove,list,sign} ...

positional arguments:
  {add,remove,list,sign}

options:
  -h, --help            show this help message and exit
  --version             show program's version number and exit
  --raw                 Output raw values, tab separated.

fario-signers add

Create a new signer for an application and approve it using a user's private key.

fario-signers add --help

usage: fario-signers add [-h] [--provider PROVIDER] [--user-fid USER_FID] [--user-key USER_KEY] [--app-fid APP_FID] [--app-key APP_KEY]

Create a new signer. Using --raw will output tx_hash, user_fis, app_fid, signer_bublic_key, signer_private_key as a tab-separated list.

options:
  -h, --help           show this help message and exit
  --provider PROVIDER  OP Eth provider endpoint
  --user-fid USER_FID  User's fid.
  --user-key USER_KEY  User's private key in hex.
  --app-fid APP_FID    Application's fid.
  --app-key APP_KEY    Application's private key in hex.

fario-signers remove

Remove a signer already approved by a user.

fario-signers remove --help

usage: fario-signers remove [-h] [--op_eth_provider OP_ETH_PROVIDER] [--user-key USER_KEY] signer

Remove a signer. Using --raw will output only the tx_hash.

positional arguments:
  signer                Signer's public key in hex.

options:
  -h, --help            show this help message and exit
  --op_eth_provider OP_ETH_PROVIDER
                        OP Eth provider endpoint
  --user-key USER_KEY   User's private key in hex.

fario-signers sign

It reads messages in "far" format from stdin, signs them using a new signer, and outputs them in far format to stdout.

fario-signers sign --help

usage: fario-signers sign [-h] [--signer SIGNER] [--keep-hash]

Read messages and sign (or re-sign) using a new signer. Reads from stdin, writes to stdout. In and out are in fario format.

options:
  -h, --help       show this help message and exit
  --signer SIGNER  Signer's private key
  --keep-hash      Do not change the message hash.

Example: Compare the output (hashes, signers and signatures) of the following commands:

1. fario-out --casts --limit=5 280 | fario2json | jq
2. fario-out --casts --limit=5 280 | fario-signers sign <key> | fario2json

You could pipe the output of fario-signers sign to fario-in to post the new messages to a hub.

Posting these messages to a hub can fail for various reasons:

1. Message hash is already posted. (i.e. you can repost the same message, even if the signature is changed)
2. Signer is not approved by the user: You can't post messages from an fid that has not approved the signer.
3. Message deleted: in many cases, deleting a cast leaves a "remove" message on the hubs, containing the removed messages hash. You can't post a new message with the same hash.

VERY INTERESTING USE CASE

However, you can use fario-out to backup your content, remove a signer (which results in all mesages signed by it to be removed!), then use fario-signers sign and fario-in to re-sign them with a new signer and upload them to farcaster!

fario-account

Displays detailed information about an fid.

usage: fario-account [-h] [--version] [--raw] [--hub HUB] [--fid] [--fname] [--name] [--addr] [--storage-rent] [--storage-limits] [--storage-usage] [--recovery] [--all] {byfid,byname} ...

positional arguments:
  {byfid,byname}

options:
  -h, --help        show this help message and exit
  --version         show program's version number and exit
  --raw             Output raw values, tab separated.
  --hub HUB         Use the hub at <HUB>. Ex. --hub 192.168.1.1:2283
  --fid             Print fid
  --fname           Print fname
  --name            Print name
  --addr            Print custody address
  --storage-rent    Print storage rent events
  --storage-limits  Print storage limits
  --storage-usage   Print storage usage
  --recovery        Print recovery address
  --all             Print all available information

Example

$ fario-account --all byname dwr

address         0x6b0bda3f2ffed5efc83fa8c024acff1dd45793f1
fname           dwr
name            dwr.eth
