Python implementation of untyped plutus language core
Project description
Untyped Plutus Language Core
This is a basic library to support creating and manipulating programs written in UPLC.
Installation
Install anything between python 3.8 and 3.10. Then run
pip install uplc
Secp256k1
If you want to use the builtin functions for verification of ECDSA and Schnorr signatures,
follow the instructions to install libsecp256k1
with schnorr support enabled:
This makes sure that the exact same version is used that is used in the cardano-node
.
Usage
This tool may be used to parse, reformat (/dump), evaluate or build contract artifacts from UPLC code.
# Check validity of a source file
uplc parse examples/fibonacci.uplc
# Dump a source file in either the aiken or the plutus dialect
uplc dump examples/fibonacci.uplc --dialect aiken
uplc dump examples/fibonacci.uplc --dialect plutus --unique-varnames
# Evaluate a UPLC program on UPLC input
uplc eval examples/fibonacci.uplc "(con integer 5)"
# Build smart contract artifacts from the UPLC program
uplc build examples/fibonacci.uplc
# This package can also be used to analyze built contracts (output from any Smart Contract Language)
uplc dump build/fibonacci/script.cbor --from-cbor
# Show all options
uplc --help
Scope and Contributions
This is a side product of the development of a pythonic smart contract language for the Cardano blockchain and hence much tailored to the needs of that development.
Contributions are very welcome.
