# Contributing to PyQtGraph
|
||||
|
||||
Contributions to pyqtgraph are welcome!
|
||||
|
||||
Please use the following guidelines when preparing changes:
|
||||
|
||||
## Submitting Code Changes
|
||||
|
||||
* The preferred method for submitting changes is by github pull request against the "develop" branch.
|
||||
* Pull requests should include only a focused and related set of changes. Mixed features and unrelated changes may be rejected.
|
||||
* For major changes, it is recommended to discuss your plans on the mailing list or in a github issue before putting in too much effort.
|
||||
* The following deprecations are being considered by the maintainers
|
||||
* `pyqtgraph.opengl` may be deprecated and replaced with `VisPy` functionality
|
||||
* After v0.11, pyqtgraph will adopt [NEP-29](https://numpy.org/neps/nep-0029-deprecation_policy.html) which will effectively mean that python2 support will be deprecated
|
||||
* Qt4 will be deprecated shortly, as well as Qt5<5.9 (and potentially <5.12)
|
||||
|
||||
## Documentation
|
||||
|
||||
* Writing proper documentation and unit tests is highly encouraged. PyQtGraph uses pytest style testing, so tests should usually be included in a tests/ directory adjacent to the relevant code.
|
||||
* Documentation is generated with sphinx; please check that docstring changes compile correctly
|
||||
|
||||
## Style guidelines
|
||||
|
||||
### Rules
|
||||
|
||||
* PyQtGraph prefers PEP8 for most style issues, but this is not enforced rigorously as long as the code is clean and readable.
|
||||
* Use `python setup.py style` to see whether your code follows the mandatory style guidelines checked by flake8.
|
||||
* Exception 1: All variable names should use camelCase rather than underscore_separation. This is done for consistency with Qt
|
||||
* Exception 2: Function docstrings use ReStructuredText tables for describing arguments:
|
||||
|
||||
```text
|
||||
============== ========================================================
|
||||
**Arguments:**
|
||||
argName1 (type) Description of argument
|
||||
argName2 (type) Description of argument. Longer descriptions must
|
||||
be wrapped within the column guidelines defined by the
|
||||
"====" header and footer.
|
||||
============== ========================================================
|
||||
```
|
||||
|
||||
QObject subclasses that implement new signals should also describe
|
||||
these in a similar table.
|
||||
|
||||
### Pre-Commit
|
||||
|
||||
PyQtGraph developers are highly encouraged to (but not required) to use [`pre-commit`](https://pre-commit.com/). `pre-commit` does a number of checks when attempting to commit the code to ensure it conforms to various standards, such as `flake8`, utf-8 encoding pragma, line-ending fixers, and so on. If any of the checks fail, the commit will be rejected, and you will have the opportunity to make the necessary fixes before adding and committing a file again. This ensures that every commit made conforms to (most) of the styling standards that the library enforces; and you will most likely pass the code style checks by the CI.
|
||||
|
||||
To make use of `pre-commit`, have it available in your `$PATH` and run `pre-commit install` from the root directory of PyQtGraph.
|
||||
|
||||
## Testing Setting up a test environment
|
||||
|
||||
### Dependencies
|
||||
|
||||
* tox
|
||||
* tox-conda
|
||||
* pytest
|
||||
* pytest-cov
|
||||
* pytest-xdist
|
||||
* Optional: pytest-xvfb
|
||||
|
||||
If you have `pytest<5` (used in python2), you may also want to install `pytest-faulthandler==1.6` plugin to output extra debugging information in case of test failures. This isn't necessary with `pytest>=5`
|
||||
|
||||
### Tox
|
||||
|
||||
As PyQtGraph supports a wide array of Qt-bindings, and python versions, we make use of `tox` to test against most of the configurations in our test matrix. As some of the qt-bindings are only installable via `conda`, `conda` needs to be in your `PATH`, and we utilize the `tox-conda` plugin.
|
||||
|
||||
* Tests for a module should ideally cover all code in that module, i.e., statement coverage should be at 100%.
|
||||
* To measure the test coverage, un `pytest --cov -n 4` to run the test suite with coverage on 4 cores.
|
||||
|
||||
### Continous Integration
|
||||
|
||||
For our Continuous Integration, we utilize Azure Pipelines. Tested configurations are visible on [README](README.md). More information on coverage and test failures can be found on the respective tabs of the [build results page](https://dev.azure.com/pyqtgraph/pyqtgraph/_build?definitionId=1)

There are many different ways to install pyqtgraph, depending on your needs:
|
||||
|
||||
* The most common way to install pyqtgraph is with pip::
|
||||
|
||||
$ pip install pyqtgraph
|
||||
|
||||
Some users may need to call ``pip3`` instead. This method should work on
|
||||
all platforms.
|
||||
* To get access to the very latest features and bugfixes, clone pyqtgraph from
|
||||
github::
|
||||
|
||||
$ git clone https://github.com/pyqtgraph/pyqtgraph
|
||||
|
||||
Now you can install pyqtgraph from the source::
|
||||
|
||||
$ python setup.py install
|
||||
|
||||
..or you can simply place the pyqtgraph folder someplace importable, such as
|
||||
inside the root of another project. PyQtGraph does not need to be "built" or
|
||||
compiled in any way.
|
||||
* Packages for pyqtgraph are also available in a few other forms:
|
||||
|
||||
* **Anaconda**: ``conda install pyqtgraph``
|
||||
* **Debian, Ubuntu, and similar Linux:** Use ``apt install python-pyqtgraph`` or
|
||||
download the .deb file linked at the top of the pyqtgraph web page.
|
||||
* **Arch Linux:** has packages (thanks windel). (https://aur.archlinux.org/packages.php?ID=62577)
|
||||
* **Windows:** Download and run the .exe installer file linked at the top of the pyqtgraph web page.

Requirements
|
||||
============
|
||||
|
||||
PyQtGraph depends on:
|
||||
|
||||
|
||||
* Python 2.7 or Python 3.x
|
||||
* A Qt library such as PyQt4, PyQt5, PySide, or PySide2
|
||||
* numpy
|
||||
|
||||
The easiest way to meet these dependencies is with ``pip`` or with a scientific python
|
||||
distribution like Anaconda.

|
||||
|

$ pip install pyqtgraph

|

-----
|
||||
|
||||
pyqtgraph is on the default Anaconda channel::
|
||||
|
||||
$ conda install pyqtgraph
|

|

It is also available in the conda-forge channel::
|

|

$ conda install -c conda-forge pyqtgraph
|

From Source
|
||||
-----------
|
||||
|
||||
To get access to the very latest features and bugfixes you have three choices:
|
||||
|
||||
1. Clone pyqtgraph from github::
|
||||
|
||||
$ git clone https://github.com/pyqtgraph/pyqtgraph
|
||||
$ cd pyqtgraph
|
||||
|
||||
Now you can install pyqtgraph from the source::
|
||||
|
||||
$ pip install .
|
||||
|
||||
2. Directly install from GitHub repo::
|
||||
|
||||
$ pip install git+git://github.com/pyqtgraph/pyqtgraph.git@develop
|
||||
|
||||
You can change ``develop`` of the above command to the branch name or the
|
||||
commit you prefer.
|
||||
|
||||
3. You can simply place the pyqtgraph folder someplace importable, such as
|
||||
inside the root of another project. PyQtGraph does not need to be "built" or
|
||||
compiled in any way.

||||

* **Right button drag:** Scales the scene. Dragging left/right scales horizontally; dragging up/down scales vertically (although some scenes will have their x/y scales locked together). If there are x/y axes fisible in the scene, then right-dragging over the axis will _only_ affect that axis.
