Unofficial Python library for STEEM
Project description
beem - Unofficial Python Library for Steem
beem is an unofficial python library for steem, which is created new from scratch from python-bitshares The library name is derived from a beam maschine, similar to the analogy between steem and steam. beem includes python-graphenelib.
Current build status
Support & Documentation
You may find help in the beem-discord-channel. The discord channel can also be used to discuss things about beem.
A complete library documentation is available at beem.readthedocs.io.
Advantages over the official steem-python library
High unit test coverage
Support for websocket nodes
Native support for new Appbase calls
Node error handling and automatic node switching
Usage of pycryptodomex instead of the outdated pycrypto
Complete documentation of beempy and all classes including all functions
steemconnect integration
Works on read-only systems
Own BlockchainObject class with cache
Contains all broadcast operations
Estimation of virtual account operation index from date or block number
the command line tool beempy uses click and has more commands
SteemNodeRPC can be used to excecute even not implemented RPC-Calls
More complete implemention
Installation
The minimal working python version is 2.7.x. or 3.4.x
beem can be installed parallel to python-steem.
For Debian and Ubuntu, please ensure that the following packages are installed:
sudo apt-get install build-essential libssl-dev python-devFor Fedora and RHEL-derivatives, please ensure that the following packages are installed:
sudo yum install gcc openssl-devel python-develFor OSX, please do the following:
brew install openssl export CFLAGS="-I$(brew --prefix openssl)/include $CFLAGS" export LDFLAGS="-L$(brew --prefix openssl)/lib $LDFLAGS"
For Termux on Android, please install the following packages:
pkg install clang openssl-dev python-devSigning and Verify can be fasten (200 %) by installing cryptography:
pip install -U cryptographyInstall beem by pip:
pip install -U beem
You can install beem from this repository if you want the latest but possibly non-compiling version:
git clone https://github.com/holgern/beem.git cd beem python setup.py build python setup.py install --user
Run tests after install:
pytest
Installing beem with conda-forge
Installing beem from the conda-forge channel can be achieved by adding conda-forge to your channels with:
conda config --add channels conda-forge
Once the conda-forge channel has been enabled, beem can be installed with:
conda install beem
Signing and Verify can be fasten (200 %) by installing cryptography:
conda install cryptography
CLI tool beempy
A command line tool is available. The help output shows the available commands:
beempy –help
Stand alone version of CLI tool beempy
With the help of pyinstaller, a stand alone version of beempy was created for Windows, OSX and linux. Each version has just to be unpacked and can be used in any terminal. The packed directories can be found under release. Each release has a hash sum, which is created directly in the build-server before transmitting the packed file. Please check the hash-sum after downloading.
