2. install all dependencies following the instructions in installing-vyper
3. Write a contract in the examples directory
4. Compile the contract using the nicoMain.py script
5. Install the Ethereum Virtual Machine Aleth
6. Interact with the EVM using the aleth-vm command
7. For more instructions check the comments in nicoMain.py

Getting Started

See Installing Vyper to install vyper. See Tools and Resources for an additional list of framework and tools with vyper support. See Documentation for the documentation and overall design goals of the Vyper language.

Note: Vyper is beta software, use with care

Installation

See the Vyper documentation for build instructions.

Compiling a contract

To compile a contract, use:

vyper your_file_name.vy

Alternative for GitHub syntax highlighting: Add a .gitattributes file with the line *.vy linguist-language=Python

There is also an online compiler available you can use to experiment with the language and compile to bytecode and/or LLL.

Note: While the vyper version of the online compiler is updated on a regular basis it might be a bit behind the latest version found in the master branch of this repository.

Testing (using pytest)

(Complete installation steps first.)

python setup.py test
