Python-based EPM (Ethereum Package Manager) for Serpent 2 contract deployment using YAML for package definitions.
pip install pyepm
git clone https://github.com/etherex/pyepm.git
cd pyepm
pip install -e .
cpp-ethereum node with JSONRPC
First run pyepm -h to create a config file in ~/.pyepm/config on Linux and OSX and ~/AppData/Roaming/PyEPM on Windows.
Then edit the configuration file, make sure you set the address from which to deploy contracts.
You will need a package definition file in YAML format to get started (see example below). You can use your deployed contracts' names as variables (prefixed with $) in later transact or call steps, making contract initialization a lot easier and less dependent on fixed contract addresses.
-
# Set some variables.
set:
NameReg: "0x72ba7d8e73fe8eb666ea66babc8116a41bfb10e2"

-
# Make transactions, here we register the previously deployed
# 'Subcurrency' contract with the global NameReg

pyepm YourPackageDefinitions.yaml
usage: pyepm [-h] [-v] [-r HOST] [-p PORT] [-a ADDRESS] [-g GAS] [-c CONFIG]
[-V VERBOSITY] [-L LOGGING]
filename [filename ...]
positional arguments:
filename Package definition filenames in YAML format
optional arguments:
-h, --help show this help message and exit
-v, --version show program's version number and exit
-r HOST, --host HOST <host> JSONRPC host (default: 127.0.0.1).
-p PORT, --port PORT <port> JSONRPC port (default: 8080).
-a ADDRESS, --address ADDRESS
Set the address from which to deploy contracts.
-g GAS, --gas GAS Set the default amount of gas for deployment.
-c CONFIG, --config CONFIG
Use another configuration file.
-V VERBOSITY, --verbose VERBOSITY
<0 - 3> Set the log verbosity from 0 to 3 (default: 1)
-L LOGGING, --logging LOGGING
<logger1:LEVEL,logger2:LEVEL> set the console log
level for logger1, logger2, etc. Empty loggername
means root-logger, e.g. ':DEBUG,:INFO'. Overrides '-V'
- Support using variables across multiple definition files
- Export addresses of deployed contracts in a json file
- Post-deployment hooks
- Support named values (1 ether)
