A tool for Ethereum smart contract development.

Quickstart

pip install twig

Developer Setup

If you would like to hack on twig, please check out the Ethereum Development Tactical Manual for information on how we do:

  • Testing
  • Pull Requests
  • Code Style
  • Documentation

Development Environment Setup

You can set up your dev environment with:

git clone git@github.com:ethereum/twig.git
cd twig
virtualenv -p python3 venv
. venv/bin/activate
pip install -e .[dev]

Testing Setup

During development, you might like to have tests run on every file save.

Show flake8 errors on file change:

# Test flake8
when-changed -v -s -r -1 twig/ tests/ -c "clear; flake8 twig tests && echo 'flake8 success' || echo 'error'"

Run multi-process tests in one command, but without color:

# in the project root:
pytest --numprocesses=4 --looponfail --maxfail=1
# the same thing, succinctly:
pytest -n 4 -f --maxfail=1

Run in one thread, with color and desktop notifications:

cd venv
ptw --onfail "notify-send -t 5000 'Test failure ⚠⚠⚠⚠⚠' 'python 3 test on twig failed'" ../tests ../twig

Release setup

For Debian-like systems:

apt install pandoc

To release a new version:

make release bump=$$VERSION_PART_TO_BUMP$$

How to bumpversion

The version format for this repo is {major}.{minor}.{patch} for stable, and {major}.{minor}.{patch}-{stage}.{devnum} for unstable (stage can be alpha or beta).

To issue the next version in line, specify which part to bump, like make release bump=minor or make release bump=devnum. This is typically done from the master branch, except when releasing a beta (in which case the beta is released from master, and the previous stable branch is released from said branch). To include changes made with each release, update “docs/releases.rst” with the changes, and apply commit directly to master before release.

If you are in a beta version, make release bump=stage will switch to a stable.

To issue an unstable version when the current version is stable, specify the new version explicitly, like make release bump="--new-version 4.0.0-alpha.1 devnum"
