pybadges

pybadges is a Python library and command line tool that allows you to create Github-style badges as SVG images. For example:

The aesthetics of the generated badges matches the visual design found in this specification.

The implementation of the library was heavily influenced by Shields.io and the JavaScript gh-badges library.

Getting Started

Installing

pybadges can be installed using pip:

pip install pybadges

To test that installation was successful, try:

python -m pybadges --left-text=build --right-text=failure --right-color='#c00' --browser

You will see a badge like this in your browser:

Usage

pybadges can be used both from the command line and as a Python library.

The command line interface is a great way to experiment with the API before writing Python code.

Command line usage

Complete documentation of pybadges command arguments can be found using the --help flag:

python -m pybadges --help

But the following usage demonstrates every interesting option:

python -m pybadges \
    --left-text=complete \
    --right-text=example \
    --left-color=green \
    --right-color='#fb3' \
    --left-link=http://www.complete.com/ \
    --right-link=http://www.example.com \
    --logo='data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAIAAAACCAIAAAD91JpzAAAAD0lEQVQI12P4zwAD/xkYAA/+Af8iHnLUAAAAAElFTkSuQmCC' \
    --browser

Note that the --logo option can include a regular URL:

python -m pybadges \
    --left-text="python" \
    --right-text="3.2, 3.3, 3.4, 3.5, 3.6" \
    --whole-link="https://www.python.org/" \
    --browser \
    --logo='https://dev.w3.org/SVG/tools/svgweb/samples/svg-files/python.svg'

Library usage

pybadges is primarily meant to be used as a Python library.

from pybadges import badge
s = badge(left_text='coverage', right_text='23%', right_color='red')
# s is a string that contains the badge data as an svg image.
print(s[:40]) # => <svg height="20" width="191.0" xmlns="ht

The keyword arguments to badge() are identical to the command flags names described above except with keyword arguments using underscore instead of hyphen/minus (e.g. --left-text => left_text=)

Caveats

• pybadges uses a pre-calculated table of text widths and kerning distances (for western glyphs) to determine the size of the badge. So Eastern European languages may be rendered less well than Western European ones:

  

  and glyphs not present in Deja Vu Sans (the default font) may be rendered very poorly:

  

• pybadges does not have any explicit support for languages that are written right-to-left (e.g. Arabic, Hebrew) and the displayed text direction may be incorrect:

  

Development

git clone https://github.com/google/pybadges.git
cd pybadges
python -m virtualenv venv
source venv/bin/activate
# Installs in edit mode and with development dependencies.
pip install -e .[dev]
nox
