beem is a python library for steem. beem has now 425 unit tests and a coverage of 84 %. The current version is 0.19.23. Please visit my discord channel for answering question or discussing beem: https://discord.gg/4HM592V

beem has gained some attention lately and there are now some visitors in my github repository:

What feature(s) did you add?

The following commands are added to the command line tool beempy:

currentnode

beempy currentnode shows the current node url and its version.

mute

beempy mute test mutes account test.

muter

beempy muter shows a summarize about all account that mutes the default account.

muting

beempy muting shows a summarize about accounts which where muted by the default account.

nextnode

beempy nextnode switches to the next node in line.

pingnode

beempy pingnode measures how long a get_config rpc call takes. The output is in milli seconds.

power

beempy power shows vote power, balance and account bandwidth.

votes

beempy votes --direction in --days 3 shows the incoming votes of the last 3 days.

beempy votes --direction out --days 1 shows the outgoing votes of the last day.

Support for read-only systems is added

beem can now be used in a read-only system. The config variables can not be stored and the wallet can not be used in a read-only system.

Writing operation in a read-only system lead to an NoWriteAccess exception

The following operation should be avoided in a read-only system:

• storing configs:

from beem import Steem
stm = Steem()
stm.set_default_account("test")
stm.config["default_account"] = "test"

• using the wallet

Using private keys in a read-only system

Private keys must be provided directly to the Steem object:

from beem import Steem
stm = Steem(keys=[wif])

It is also possible to build the transaction by hand:

from beem.transactionbuilder import TransactionBuilder
from beembase.operations import Transfer
tx = TransactionBuilder()
tx.appendOps(Transfer(**{"from": 'user_a',
                         "to": 'user_b',
                         "amount": '1.000 SBD',
                         "memo": 'test 2'}))
tx.appendWif('5.....') # active private key
tx.sign()
tx.broadcast()

Receiving more than one account in one rpc call

from beem.account import Accounts
account_list = ["utopian-io", "busy.org", "minnowsupport"]
a = Accounts(account_list)
a

[<Account utopian-io>, <Account busy.org>, <Account minnowsupport>]
