Commands

Common options

  • datadir: The directory that contains aelf-command files, such as encrypted account info keyStore files. Default to be {home}/.local/share/aelf

  • endpoint: The endpoint for the RPC service.

  • account: The account to be used to interact with the blockchain endpoint.

  • password: The password for unlocking the given account.

You can specified options above in several ways, and the priority is in the order of low to high.

  1. export variables in shell.

    # This is datadir
    $ export AELF_CLI_DATADIR=/Users/{you}/.local/share/aelf
    # This is endpoint
    $ export AELF_CLI_ENDPOINT=http://127.0.0.1:8000
    # This is account
    $ export AELF_CLI_ACCOUNT=2Ue31YTuB5Szy7c...gtGi5uMQBYarYUR5oGin1sys6H
  2. aelf-command global .aelfrc config file

    The global config file is stored in the <datadir>/.aelfrc file, you can read the config file, but better not modify it by yourself.

    Modify this config file by aelf-command config.

    • set: set and save config in the file, remember just set the datadir, endpoint, account, password four keys.

      $ aelf-command config set endpoint http://127.0.0.1:8000
      ✔ Succeed!
      $ aelf-command config -h
      Usage: aelf-command config [options] <flag> [key] [value]
      get, set, delete or list aelf-command config
      Options:
      -h, --help output usage information
      Examples:
      aelf-command config get <key>
      aelf-command config set <key> <value>
      aelf-command config delete <key>
      aelf-command config list
    • get: get the value of given key from global .aelfrc file

      $ aelf-command config get endpoint
      http://127.0.0.1:8000
    • delete: delete the <key, value> from global .aelfrc file by a given key

      $ aelf-command config delete endpoint
      ✔ Succeed!
    • list: get the list of all configs stored in global .aelfrc file

      $ aelf-command config list
      endpoint=http://127.0.0.1:8000
      password=password

      Remember config command only can be used to modify the global .aelfrc file for now, more usages such as modify working directory will be implemented in later.

  3. aelf-command working directory .aelfrc file

    The current working directory of aelf-command can have a file named .aelfrc and store configs, the format of this file is like global .aelfrc file:

    endpoint http://127.0.0.1:8000
    password yourpassword

    each line is <key, value> config and a whitespace is needed to separate them.

  4. aelf-command options.

    You can give common options by passing them in CLI parameters.

    aelf-command console -a sadaf -p password -e http://127.0.0.1:8000

    Notice the priority, the options given in higher priority will overwrite the lower priority.

create - Create a new account

This command will create a new account.

$ aelf-command create -h
Usage: aelf-command create [options] [save-to-file]
create a new account
Options:
-c, --cipher [cipher] Which cipher algorithm to use, default to be aes-128-ctr
-h, --help output usage information
Examples:
aelf-command create <save-to-file>
aelf-command create

Example:

  • Specify the cipher way to encrypt account info by passing option -c [cipher], such as:

    aelf-command create -c aes-128-cbc

load - Load an account by a given private key or mnemonic

This command allow you load an account from backup.

# load from mnemonic
$ aelf-command load 'great mushroom loan crisp ... door juice embrace'
# load from private key
$ aelf-command load 'e038eea7e151eb451ba2901f7...b08ba5b76d8f288'
# load from prompting
$ aelf-command load
? Enter a private key or mnemonic › e038eea7e151eb451ba2901f7...b08ba5b76d8f288
...

wallet - Show wallet details which include private key, address, public key and mnemonic

proposal - Create a proposal

There are three kinds of proposal contracts in AElf:

  • AElf.ContractNames.Parliament

  • AElf.ContractNames.Referendum

  • AElf.ContractNames.Association

depending on your needs you can choose one and create a proposal.

  • Get an organization address or create one

If you want to call a contract method by creating a proposal and released it, the released transaction result could be confusing, you can use another aelf-command sub-command to get the readable result;

Take the example above which has deployed a smart contract by proposal, the contract address is necessary for sending transactions. The contract address has been given but need to be decoded. We supply aelf-command event to decode the results.

Pass the transaction id as a parameter:

$ aelf-command event fe1974fde291e44e16c55db666f2c747323cdc584d616de05c88c8bae18ecceb

}
}

The Result field is the decoded result, in this example, the Result.address is the new deployed contract address.

For more details, check the descriptions of aelf-command event.

    • You must input contract method parameters in the prompting way, note that you can input a relative or absolute path of contract file to pass a file to aelf-command, aelf-command will read the file content and encode it as a base64 string.

    • After call ProposeNewContract, you need to wait for the organization members to approve your proposal and you can release your proposal by calling releaseApprove and releaseCodeCheck in this order.

This command get the Log field of a transaction result and deserialize the Log field with the correspond protobuf descriptors.

A transaction may be related with several Contract Method's events, so the transaction result can include several Logs.

In each item:

  • Address: the contract address.

  • Name: name of event published from related contract method.

  • Indexed: indexed data of event in type of base64

  • NoIndexed: no indexed data of event in type of base64.

  • Result: the decoded result, this is readable and you can use it and get what the fields means inside the Result by reading the contract documents or contract related protobuf files.

    In this example, you can read the protobuf file;

dapp-server - Start a socket.io server for supplying services for dApps

If you're developing a dApp and you need an environment to hold wallet info and connect to the AElf chain, you can use this sub-command to start a server for dApp local development.

$ aelf-command dapp-server
AElf [Info]: DApp server is listening on port 35443
# or listen on a specified port
$ aelf-command dapp-server --port 40334
AElf [Info]: DApp server is listening on port 40334

This server uses Socket.io to listen on local port 35443 and you can use aelf-bridge to connect to this server like this:

import AElfBridge from 'aelf-bridge';
const bridgeInstance = new AElfBridge({
proxyType: 'SOCKET.IO',
socketUrl: 'http://localhost:35443',
channelType: 'ENCRYPT'
});
// connect to dapp-server
bridgeInstance.connect().then(console.log).catch(console.error);

checkout more information in aelf-bridge and aelf-bridge-demo.
