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:

.. code-block:: bash

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:


.. image:: https://github.com/jongracecox/anybadge/blob/master/examples/pylint.svg
:target: https://github.com/jongracecox/anybadge/blob/master/examples/pylint.svg
:alt: 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:

.. code-block:: python

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
============

You can install the latest release of ``anybadge`` using ``pip``\ :

.. code-block::

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:

.. code-block:: bash

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.

Options
-------

These are the command line options:

.. code-block::

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'
|
