# Getting Started

See [Installing Vyper](http://docs.vyperlang.org/en/latest/installing-vyper.html) to install vyper.

See [Tools and Resources](https://github.com/vyperlang/vyper/wiki/Vyper-tools-and-resources) for an additional list of framework and tools with vyper support.

See [Documentation](http://docs.vyperlang.org/en/latest/index.html) for the documentation and overall design goals of the Vyper language.

See [learn.vyperlang.org](https://learn.vyperlang.org/) for **learning Vyper by building a Pokémon game**.

See [try.vyperlang.org](https://try.vyperlang.org/) to use Vyper in a hosted jupyter environment!

**Note: Vyper is beta software, use with care**

# Installation

See the [Vyper documentation](https://docs.vyperlang.org/en/latest/installing-vyper.html)

for build instructions.

# Compiling a contract

To compile a contract, use:

```bash

vyper your_file_name.vy

```

***generate bytecode***

    vyper -f bytecode file-name.vy > file-name.bin

***generate abi***

    vyper -f abi file-name.vy > file-name.abi

There is also an [online compiler](https://vyper.online/) available you can use to experiment with

the language and compile to ``bytecode`` and/or ``IR``.

**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](https://docs.vyperlang.org/en/latest/installing-vyper.html) first.)

```bash

make dev-init

python setup.py test

```

## Developing (working on the compiler)

A useful script to have in your PATH is something like the following:

```bash

$ cat ~/.local/bin/vyc

#!/usr/bin/env bash

PYTHONPATH=. python vyper/cli/vyper_compile.py "$@"

```

To run a python performance profile (to find compiler perf hotspots):

```bash

PYTHONPATH=. python -m cProfile -s tottime vyper/cli/vyper_compile.py "$@"

```

To get a call graph from a python profile, https://stackoverflow.com/a/23164271/ is helpful.
