Installation

As a binary (recommended)

You can download a10y in the release section, by choosing the binary that suits your system.

In a python virtual environment

Clone the sources, create a virtual environment, install dependencies and run as a python script:

git clone https://github.com/EIDA/a10y.git
cd a10y
python -m venv venv
source venv/bin/activate
python -m pip install -r requirements.txt
python a10y.py

With conda

Supposing you have anaconda or miniconda installed in your system, follow the steps below.

Clone the sources, create a conda environment, install dependencies and run as a python script:

git clone https://github.com/EIDA/a10y.git
cd a10y
conda create --name a10yEnv python=3.8
conda activate a10yEnv
python -m pip install -r requirements.txt
python a10y.py

With pyinstaller

This method is intended to provide a portable standalone executable for the application.

The executable can be created on every system using pyinstaller.

It has been tested in an Ubuntu machine with pyinstaller version 6.3.0.

After having created a python or conda environment, activated it and installed dependencies as shown above, install pyinstaller and execute it as below:

python -m pip install pyinstaller
pyinstaller --onefile --add-data "a10y.css:." a10y.py

This will create:

• an a10y.spec file
• a build folder
• a dist folder

Into dist folder you can find the final executable. By executing through terminal, as every other executable in your system, it opens the application:

cd dist
./a10y

The final executable can be redistributed and be used as a standalone executable to any system with similar operating system as the one in which it was created.

Options

The application can be executed with the following options:

• -p or --post followed by path that points to a file to start the application using that file for making POST requests to availability webservice
• -c or --config followed by path that points to a configuration file to start the application using specific default values for requests

Configuration

A config.toml file with some default values for the parameters of the requests can be provided, so that the application starts with them as selected.

With the configuration file, you can set your default values for starttime, endtime, quality, mergegaps or merge policy.

The application looks for the configuration file in this order:

• with the -c or --config command line option
• in the $XDG_CONFIG_DIR/a10y directory
• in the directory of the application script

Customizing the layout

All the layout colors are described in a CSS file a10y.css that can be customized. This is not possible at the moment with the binary release, which embeds the CSS file.
