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.

Demo

You can find a repl.it demo here. This will allow you to see what the package can do and play with it to test outputs.

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

=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= --file= 

For example:

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

Colors

Anybadge comes with some pre-defined colors, which can be referred to by name. It also supports the use of custom colors by using the hex representation of the color. Both color types can be used in the

default_color
,
text_color
and
thresholds
attributes.

Here is a Python example showing use of a named color and a custom color.

import anybadge

badge = anybadge.Badge(label='custom color', value='teal', default_color='teal', num_padding_chars=1) badge = anybadge.Badge(label='custom color', value='teal', default_color='#008080', num_padding_chars=1)

Available named colors are:

| Color Name | Hex Code | Example | | ---------- | -------- | ------- | | aqua | #00FFFF | | | black | #000000 | | | blue | #0000FF | | | brightred | #FF0000 | | | brightyellow | #FFFF00 | | | fuchsia | #FF00FF | | | gray | #808080 | | | green | #4C1 | | | lightgrey | #9F9F9F | | | lime | #00FF00 | | | maroon | #800000 | | | navy | #000080 | | | olive | #808000 | | | orange | #FE7D37 | | | purple | #800080 | | | red | #E05D44 | | | silver | #C0C0C0 | | | teal | #008080 | | | white | #FFFFFF | | | yellow | #DFB317 | | | yellowgreen | #A4A61D | |

This table was generated with the following code:

print("""| Color Name | Hex Code | Example |
| ---------- | -------- | ------- |""")
for color, hex in sorted(anybadge.COLORS.items()):
    file = 'examples/color_' + color + '.svg'
    url = 'https://cdn.rawgit.com/jongracecox/anybadge/master/' + file
    anybadge.Badge(label='Color', value=color, default_color=color).write_badge(file, overwrite=True)
    print("| {color} | {hex} | ![]({url}) |".format(color=color, hex=hex.upper(), url=url))

Semantic version support

Anybadge supports semantic versions for value and threshold keys. This supports color-coded badges based on version numbering. Here are some examples:

badge = Badge(
    label='Version', 
    value='3.0.0', 
    thresholds={'3.0.0': 'red', '3.2.0': 'orange', '999.0.0': 'green'}, 
    semver=True
)

In the above example the thresholds equate to the following:

  • If value is < 3.0.0 then badge will be red.
  • If value is < 3.2.0 then badge will be orange.
  • If value is < 999.0.0 then badge will be green.

Each threshold entry is used to define the upper bounds of the threshold. If you don't know the upper bound for your version number threshold you will need to provide an extreme upper bound - in this example it is

999.0.0
.

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

Thresholds based on semantic versions

anybadge --label=Version --value=2.4.5 --file=version.svg 1.0.0=red 2.4.6=orange 2.9.1=yellow 999.0.0=green

Options

These are the command line options:

positional arguments:
  args                  Pairs of =. 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. -lp LABEL_PADDING, --label-padding LABEL_PADDING Number of characters to pad on either side of the badge label. -vp VALUE_PADDING, --value-padding VALUE_PADDING Number of characters to pad on either side of the badge value. -n FONT, --font FONT "DejaVu Sans,Verdana,Geneva,sans-serif"Font name. Supported fonts: ,"Arial, Helvetica, 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::

 |  
 |  Badge class used to generate badges.
 |  
 |  Examples:
 |  
 |      Create a simple green badge:
 |  
 |      &gt;&gt;&gt; badge = Badge('label', 123, default_color='green')
 |  
 |      Write a badge to file, overwriting any existing file:
 |  
 |      &gt;&gt;&gt; badge = Badge('label', 123, default_color='green')
 |      &gt;&gt;&gt; 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:
 |  
 |      &gt;&gt;&gt; badge = Badge('pipeline', 'passing', thresholds={'passing': 'green', 'failing': 'red'})
 |      &gt;&gt;&gt; badge.badge_color
 |      'green'
 |  
 |      2.32 is not &lt;2
 |      2.32 is &lt; 4, so 2.32 yields orange
 |      &gt;&gt;&gt; badge = Badge('pylint', 2.32, thresholds={2: 'red',
 |      ...                                           4: 'orange',
 |      ...                                           8: 'yellow',
 |      ...                                           10: 'green'})
 |      &gt;&gt;&gt; badge.badge_color
 |      'orange'
 |  
 |      8 is not &lt;8
 |      8 is &lt;4, so 8 yields orange
 |      &gt;&gt;&gt; badge = Badge('pylint', 8, thresholds={2: 'red',
 |      ...                                        4: 'orange',
 |      ...                                        8: 'yellow',
 |      ...                                        10: 'green'})
 |      &gt;&gt;&gt; badge.badge_color
 |      'green'
 |  
 |      10 is not &lt;8, but use_max_when_value_exceeds defaults to
 |      True, so 10 yields green
 |      &gt;&gt;&gt; badge = Badge('pylint', 11, thresholds={2: 'red',
 |      ...                                         4: 'orange',
 |      ...                                         8: 'yellow',
 |      ...                                         10: 'green'})
 |      &gt;&gt;&gt; badge.badge_color
 |      'green'
 |  
 |      11 is not &lt;10, and use_max_when_value_exceeds is set to
 |      False, so 11 yields the default color '#4c1'
 |      &gt;&gt;&gt; badge = Badge('pylint', 11, use_max_when_value_exceeds=False,
 |      ...               thresholds={2: 'red', 4: 'orange', 8: 'yellow',
 |      ...                           10: 'green'})
