Simple, flexible badge generator for project badges.

Project description

Python project for generating badges for your projects

build status

Overview

anybadge can be used to add badge generation to your Python projects, and also provides a command line interface.

This utility can be used to generate .svg badge images, using configurable thresholds for coloring the badges based on the badge value. Many badge generation tools just provide the ability to specify the color of badge. anybadge allows you to specify the label, badge value, and color, but it also allows you to specify a set of thresholds that can be used to select a color based on the badge value.

anybadge may be useful for companies developing internally, or any time making calls to external badge services is not possible, or undesirable. In this situation using anybadge will be easier than running your own internal badge service.

The package can be imported into your python code, or run direct from the command line.

Basic usage

Command line

As an example, if you want to produce a pylint badge, you may run anybadge from the command line like this:

anybadge -l pylint -v 2.22 -f pylint.svg 2=red 4=orange 8=yellow 10=green

This would result in a badge like this:

pylint

In this example the label is set to “pylint”, the value “2.22”, and an output file called “pylint.svg”. The thresholds are provided in pairs of <value>=color Values can be integer or floats for ranges, and string values are also supported.

Python

Here is the same example implemented in Python code:

import anybadge

# Define thresholds: <2=red, <4=orange <8=yellow <10=green
thresholds = {2: 'red',
              4: 'orange',
              6: 'yellow',
              10: 'green'}

badge = anybadge.Badge('pylint', 2.22, thresholds=thresholds)

badge.write_badge('pylint.svg')

Installation

anybadge is available in PyPi at https://pypi.python.org/pypi/anybadge

You can install the latest release of anybadge using pip:

pip install anybadge

This will install the Python package, and also make anybadge available as a command line utility.

Getting help

To get help from the command line utility, just run:

anybadge --help

Command line usage

Output

Running the utility with the --file option will result in the .svg image being written to file. Without the --file option the .svg file content will be written to stdout, so can be redirected to a file.

Thresholds

Some thresholds have been built in to save time. To use these thresholds you can simply specify the template name instead of threshold value/color pairs.

anybadge --value=<VALUE> --file=<FILE> <TEMPLATE-NAME>

For example:

anybadge --value=2.22 --file=pylint.svg pylint

Examples

Pylint using template

anybadge --value=2.22 --file=pylint.svg pylint
pylint

Pylint using arguments

anybadge -l pylint -v 2.22 -f pylint.svg 2=red 4=orange 8=yellow 10=green
pylint

Coverage using template

anybadge --value=65 --file=coverage.svg coverage
pylint

Pipeline, using labeled colors

anybadge --label=pipeline --value=passing --file=pipeline.svg passing=green failing=red
pylint

Badge with fixed color

anybadge --label=awesomeness --value="110%" --file=awesomeness.svg --color=#97CA00
pylint

Options

These are the command line options:

 positional arguments:
   args                  Pairs of <upper>=<color>. For example 2=red 4=orange
                         6=yellow 8=good. Read this as "Less than 2 = red, less
                         than 4 = orange...".

 optional arguments:
   -h, --help            show this help message and exit
   -l LABEL, --label LABEL
                         The badge label.
   -v VALUE, --value VALUE
                         The badge value.
   -m VALUE_FORMAT, --value-format VALUE_FORMAT
                         Formatting string for value (e.g. "%.2f" for 2dp
                         floats)
   -c COLOR, --color COLOR
                         For fixed color badges use --colorto specify the badge
                         color.
   -p PREFIX, --prefix PREFIX
                         Optional prefix for value.
   -s SUFFIX, --suffix SUFFIX
                         Optional suffix for value.
   -d PADDING, --padding PADDING
                         Number of characters to pad on either side of the
                         badge text.
   -n FONT, --font FONT  "DejaVu Sans,Verdana,Geneva,sans-serif"
   -z FONT_SIZE, --font-size FONT_SIZE
                         Font size.
   -t TEMPLATE, --template TEMPLATE
                         Location of alternative template .svg file.
   -u, --use-max         Use the maximum threshold color when the value exceeds
                         the maximum threshold.
   -f FILE, --file FILE  Output file location.
   -o, --overwrite       Overwrite output file if it already exists.
   -r TEXT_COLOR, --text-color TEXT_COLOR
                         Text color. Single value affects both labeland value
                         colors. A comma separated pair affects label and value
                                 text respectively.

Examples
--------

Here are some usage specific command line examples that may save time on defining
thresholds.

Pylint::

anybadge.py --value=2.22 --file=pylint.svg pylint
anybadge.py --label=pylint --value=2.22 --file=pylint.svg 2=red 4=orange 8=yellow 10=green

Coverage::

anybadge.py --value=65 --file=coverage.svg coverage
anybadge.py --label=coverage --value=65 --suffix='%%' --file=coverage.svg 50=red 60=orange 80=yellow 100=green

CI Pipeline::

anybadge.py --label=pipeline --value=passing --file=pipeline.svg passing=green failing=red

DESCRIPTION
   A Python module for generating badges for your projects, with a focus on
   simplicity and flexibility.

CLASSES
   __builtin__.object
       Badge

   class Badge(__builtin__.object)
    |  Badge class used to generate badges.
    |
    |  Examples:
    |
    |      Create a simple green badge:
    |
    |      >>> badge = Badge('label', 123, default_color='green')
    |
    |      Write a badge to file, overwriting any existing file:
    |
    |      >>> badge = Badge('label', 123, default_color='green')
    |      >>> badge.write_badge('demo.svg', overwrite=True)
    |
    |      Here are a number of examples showing thresholds, since there
    |      are certain situations that may not be obvious:
    |
    |      >>> badge = Badge('pipeline', 'passing', thresholds={'passing': 'green', 'failing': 'red'})
    |      >>> badge.badge_color
    |      'green'
    |
    |      2.32 is not <2
    |      2.32 is < 4, so 2.32 yields orange
    |      >>> badge = Badge('pylint', 2.32, thresholds={2: 'red',
    |      ...                                           4: 'orange',
    |      ...                                           8: 'yellow',
    |      ...                                           10: 'green'})
    |      >>> badge.badge_color
    |      'orange'
    |
    |      8 is not <8
    |      8 is <4, so 8 yields orange
    |      >>> badge = Badge('pylint', 6, thresholds={2: 'red',
    |      ...                                        4: 'orange',
    |      ...                                        8: 'yellow',
    |      ...                                        10: 'green'})
    |      >>> badge.badge_color
    |      'green'
    |
    |      10 is not <8, but use_max_when_value_exceeds defaults to
    |      True, so 10 yields green
    |      >>> badge = Badge('pylint', 11, thresholds={2: 'red',
    |      ...                                         4: 'orange',
    |      ...                                         8: 'yellow',
    |      ...                                         10: 'green'})
    |      >>> badge.badge_color
    |      'green'
    |
    |      11 is not <10, and use_max_when_value_exceeds is set to
    |      False, so 11 yields the default color '#a4a61d'
    |      >>> badge = Badge('pylint', 11, use_max_when_value_exceeds=False,
    |      ...               thresholds={2: 'red', 4: 'orange', 8: 'yellow',
    |      ...                           10: 'green'})
    |      >>> badge.badge_color
    |      '#a4a61d'
