Getting Set Up#
The hvPlot library is a complex project which provides a wide range of data interfaces and an extensible set of plotting backends, which means the development and testing process involves a wide set of libraries.
The hvPlot source code is stored in a Git source control repository. The first step to working on hvPlot is to install Git on to your system. There are different ways to do this depending on whether, you are using Windows, OSX, or Linux.
Developing hvPlot requires a wide range of packages that are not
easily and quickly available using pip. To make this more manageable,
core developers rely heavily on the conda package manager for the
free Anaconda Python distribution. However,
conda can also
install non-Python package dependencies, which helps streamline hvPlot
development greatly. It is strongly recommended that anyone
developing hvPlot also use
conda, and the remainder of the
instructions will assume that
conda is available.
The source code for the hvPlot project is hosted on GitHub. To clone the source repository, issue the following command:
git clone https://github.com/holoviz/hvplot.git
This will create a
hvplot directory at your file system
hvplot directory is referred to as the source
checkout for the remainder of this document.
hvPlot requires many additional packages for development and testing.
Create an empty conda environment with the name that you prefer, here we’ve
chosen hvplot_dev. Activate and configure its channels to only use
conda-forge. The former is used to install the
development versions of the other HoloViz packages, such as HoloViews or Panel.
conda create -n hvplot_dev conda activate hvplot_dev conda config --env --append channels pyviz/label/dev --append channels conda-forge conda config --env --remove channels defaults
Since hvPlot interfaces with a large range of different libraries the
full test suite requires a wide range of dependencies. To make it
easier to install and run different parts of the test suite across
different platforms hvPlot uses a library called
pyctdev to make things
more consistent and general. Specify also the desired Python version you want
to base your environment on.
You will need to pick a Python version. The best practice is to choose the minimum version currently supported by hvPlot on the main development branch. If you cannot get the minimum version installed, then try with a more recent version of Python.
conda install python=3.x pyctdev
Finally to install the dependencies required to run the full unit test suite and all the examples:
doit develop_install -o examples_tests -o tests -o examples_conda
-o doc if you want to install the dependencies required to build
pre-commit to automatically apply linting to hvPlot code.
If you intend to contribute to hvPlot we recommend you enable it with:
This will ensure that every time you make a commit linting will automatically be applied.
