Get content without using the tags api

At the moment most nodes have disabled the tags api. I added a new parameter, so that it is still possible to receive comments.

from beem import Steem
from beem.comment import Comment
stm = Steem(node="https://api.steemit.com")
c = Comment("@holger80/bumpy-start-with-hf-21-scotbot-is-running", steem_instance=stm)
set_full = set(list((c.keys())))
c = Comment("@holger80/bumpy-start-with-hf-21-scotbot-is-running", use_tags_api=False, steem_instance=stm)
set_lite = set(list((c.keys())))
print(set_full - set_lite)
print(set_lite - set_full)

Which shows the missing fields, when not using the tags_api:

{'active_votes',
 'author_reputation',
 'body_length',
 'pending_payout_value',
 'post_id',
 'promoted',
 'replies',
 'root_title',
 'url'}

and the added fields:

{'abs_rshares',
 'active',
 'allow_curation_rewards',
 'allow_replies',
 'allow_votes',
 'author_rewards',
 'children_abs_rshares',
 'max_cashout_time',
 'net_votes',
 'reward_weight',
 'root_author',
 'root_permlink',
 'total_vote_weight',
 'vote_rshares'}

use_tags_api=False can be used when the active votes of the post are not needed.

json-parsing was fixed

from beem import Steem
stm  = Steem("https://anyx.io")
from beem.block import Block
b = Block(35097419, steem_instance=stm)
print(b.operations[-22]["value"]["title"])

returns now the correct utf-8 string:
<스파이더맨 : 파 프롬 홈> 블루엔젤 니어 프롬 (퓨처) 홈 💙

Downvote manabar

from beem.account import Account
acc = Account("holger80")
print(acc.get_downvote_manabar())

returns

{'last_mana': 30121812653872, 'last_update_time': 1567022076, 'current_mana': 30429666853775, 'max_mana': 32442250357182.0, 'current_mana_pct': 93.79641214388982}

New proposal operation

The new proposal operation were added as operation, so far only update_proposal_votes was added as function to steem:

from beem import Steem
stm = Steem()
stm.wallet.unlock("...")
stm.update_proposal_votes([0], True, account="holger80")

Outlook

The following things are on my todo list:

• add the other proposal operations
• fix get_replies
• fix curation rewards calculations
• add functions to show information about proposals
• add proposal to beempy
