Allow value and thresholds to be interpreted as semantic version numbers
by passing --semver (cli) or semver=True (python).
Add docs, unittests, import error handling, cli updates, requirements updates.
* Set default padding chars to 0.5.
* Split num_padding_chars into num_label_padding_chars and num_value_padding_chars
to allow better control. Retain num_padding_chars as an input parameter, but
internally it is dropped.
* Remove padding multipliers.
* Add measurements image for developers. Helps show what each of the internal
measurements are.
* Add script to build example badges.
* Update example badges.
Reliability
=======
* Raise a value error if an invalid font is passed.
* Handle labels that are not passed as str.
* Raise a value error if an invalid color name is passed.
Testing
=======
* Expand doctests to increase test coverage.
* Add Arial size 11 font and extra font sizes (mainly for testing).
* Make parse_args and main more testable by taking args as an input parameter.
* Use useful badge text in unittest badges.
* Add template svg file for testing.
* Add HTML coverage generation to travis yaml.
* Fix int and float value detection (Closes#25)
* Fix badge_width doctest
* Ignore all svg files across the whole project. This is mainly to prevent
accidentally adding them after tests run.
Within a single Python session anybadge will use different SVG mask IDs.
This is an attempt to fix the issue where SVG files displayed in the same
HTML will re-use the same mask, and therefore appear with the same dimensions.
Uses a singleton on the class to maintain a sequence of mask ids.
Includes unittests to ensure new ID is used for each badge.
* Add __repr__ function that prints the object representation.
* Add __str__ function that prints the Badge SVG text.
Also:
* Add constructor args to the Badge class docstring.
* Change the way defaults are used in the Badge constuctor. Instead of
setting values, use None and set arguments to the default values inside
the constructor.
* Fix unittests that don't use overwrite=True.
* Use a better estimation technique to guess text widths.
* Add unittests for validating badge widths for various size badges.
* Add return types to function docstrings.
* Update relevant doctests.
