=======================
You may find help in the `crea-discord-channel`_. The discord channel can also be used to discuss things about crea.
A complete library documentation is available at `crea.readthedocs.io`_.

=================================================
* 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* Usage of pycryptodomex instead of the outdated pycrypto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 creapy and all classes including all functions
* creaconnect 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 creapy uses click and has more commands
* CreaNodeRPC can be used to execute even not implemented RPC-Calls
* More complete implemention
Installation
============
The minimal working python version is 2.7.x. or 3.4.x
crea can be installed parallel to python-crea.
For Debian and Ubuntu, please ensure that the following packages are installed:
.. code:: bash
sudo apt-get install build-essential libssl-dev python-dev
For Fedora and RHEL-derivatives, please ensure that the following packages are installed:
.. code:: bash
sudo yum install gcc openssl-devel python-devel
For 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:
.. code:: bash
pkg install clang openssl-dev python-dev
Signing and Verify can be fasten (200 %) by installing cryptography:
.. code:: bash
pip install -U cryptography
or:
.. code:: bash
pip install -U secp256k1prp
Install or update crea by pip::
pip install -U crea
You can install crea from this repository if you want the latest
but possibly non-compiling version::
git clone https://github.com/holgern/crea.git
cd crea
python setup.py build
python setup.py install --user
Run tests after install::
pytest
Installing crea with conda-forge
--------------------------------
Installing crea 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, crea can be installed with::
conda install crea
Signing and Verify can be fasten (200 %) by installing cryptography::
conda install cryptography
crea can be updated by::
conda update crea
CLI tool creapy
---------------
A command line tool is available. The help output shows the available commands:
creapy --help
Stand alone version of CLI tool creapy
--------------------------------------
With the help of pyinstaller, a stand alone version of creapy 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.
