## Contribute to freqtrade
|
|
|
|
Feel like our bot is missing a feature? We welcome your pull requests!
|
|
|
|
Issues labeled [good first issue](https://github.com/freqtrade/freqtrade/labels/good%20first%20issue) can be good first contributions, and will help get you familiar with the codebase.
|
|
|
|
Few pointers for contributions:
|
|
|
|
- Create your PR against the `develop` branch, not `stable`.
|
|
- New features need to contain unit tests, must conform to PEP8 (max-line-length = 100) and should be documented with the introduction PR.
|
|
- PR's can be declared as `[WIP]` - which signify Work in Progress Pull Requests (which are not finished).
|
|
|
|
If you are unsure, discuss the feature on our [discord server](https://discord.gg/p7nuUNVfP7) or in a [issue](https://github.com/freqtrade/freqtrade/issues) before a Pull Request.
|
|
|
|
## Getting started
|
|
|
|
Best start by reading the [documentation](https://www.freqtrade.io/) to get a feel for what is possible with the bot, or head straight to the [Developer-documentation](https://www.freqtrade.io/en/latest/developer/) (WIP) which should help you getting started.
|
|
|
|
## Before sending the PR
|
|
|
|
### 1. Run unit tests
|
|
|
|
All unit tests must pass. If a unit test is broken, change your code to
|
|
make it pass. It means you have introduced a regression.
|
|
|
|
#### Test the whole project
|
|
|
|
```bash
|
|
pytest
|
|
```
|
|
|
|
#### Test only one file
|
|
|
|
```bash
|
|
pytest tests/test_<file_name>.py
|
|
```
|
|
|
|
#### Test only one method from one file
|
|
|
|
```bash
|
|
pytest tests/test_<file_name>.py::test_<method_name>
|
|
```
|
|
|
|
### 2. Test if your code is PEP8 compliant
|
|
|
|
#### Run Flake8
|
|
|
|
```bash
|
|
flake8 freqtrade tests scripts
|
|
```
|
|
|
|
We receive a lot of code that fails the `flake8` checks.
|
|
To help with that, we encourage you to install the git pre-commit
|
|
hook that will warn you when you try to commit code that fails these checks.
|
|
Guide for installing them is [here](http://flake8.pycqa.org/en/latest/user/using-hooks.html).
|
|
|
|
##### Additional styles applied
|
|
|
|
* Have docstrings on all public methods
|
|
* Use double-quotes for docstrings
|
|
* Multiline docstrings should be indented to the level of the first quote
|
|
* Doc-strings should follow the reST format (`:param xxx: ...`, `:return: ...`, `:raises KeyError: ... `)
|
|
|
|
### 3. Test if all type-hints are correct
|
|
|
|
#### Run mypy
|
|
|
|
``` bash
|
|
mypy freqtrade
|
|
```
|
|
|
|
### 4. Ensure all imports are correct
|
|
|
|
#### Run isort
|
|
|
|
``` bash
|
|
isort .
|
|
```
|
|
|
|
## (Core)-Committer Guide
|
|
|
|
### Process: Pull Requests
|
|
|
|
How to prioritize pull requests, from most to least important:
|
|
|
|
1. Fixes for broken tests. Broken means broken on any supported platform or Python version.
|
|
1. Extra tests to cover corner cases.
|
|
1. Minor edits to docs.
|
|
1. Bug fixes.
|
|
1. Major edits to docs.
|
|
1. Features.
|
|
|
|
Ensure that each pull request meets all requirements in the Contributing document.
|
|
|
|
### Process: Issues
|
|
|
|
If an issue is a bug that needs an urgent fix, mark it for the next patch release.
|
|
Then either fix it or mark as please-help.
|
|
|
|
For other issues: encourage friendly discussion, moderate debate, offer your thoughts.
|
|
|
|
### Process: Your own code changes
|
|
|
|
All code changes, regardless of who does them, need to be reviewed and merged by someone else.
|
|
This rule applies to all the core committers.
|
|
|
|
Exceptions:
|
|
|
|
- Minor corrections and fixes to pull requests submitted by others.
|
|
- While making a formal release, the release manager can make necessary, appropriate changes.
|
|
- Small documentation changes that reinforce existing subject matter. Most commonly being, but not limited to spelling and grammar corrections.
|
|
|
|
### Responsibilities
|
|
|
|
- Ensure cross-platform compatibility for every change that's accepted. Windows, Mac & Linux.
|
|
- Ensure no malicious code is introduced into the core code.
|
|
- Create issues for any major changes and enhancements that you wish to make. Discuss things transparently and get community feedback.
|
|
- Keep feature versions as small as possible, preferably one new feature per version.
|
|
- Be welcoming to newcomers and encourage diverse new contributors from all backgrounds. See the Python Community Code of Conduct (https://www.python.org/psf/codeofconduct/).
|
|
|
|
### Becoming a Committer
|
|
|
|
Contributors may be given commit privileges. Preference will be given to those with:
|
|
|
|
1. Past contributions to Freqtrade and other related open-source projects. Contributions to Freqtrade include both code (both accepted and pending) and friendly participation in the issue tracker and Pull request reviews. Quantity and quality are considered.
|
|
1. A coding style that the other core committers find simple, minimal, and clean.
|
|
1. Access to resources for cross-platform development and testing.
|
|
1. Time to devote to the project regularly.
|
|
|
|
Being a Committer does not grant write permission on `develop` or `stable` for security reasons (Users trust Freqtrade with their Exchange API keys).
|
|
|
|
After being Committer for some time, a Committer may be named Core Committer and given full repository access.
