HTML tags

[Frulenzo]

Hi,
It would be nice to format text with some HTML tags, right? No problem, now we have it 👍
What is new?

Token Class

Just simple class which represent a token. Token has TokenType and token's data.

TokenType Enum

There is multiple token's type :

• TEXT - this type contains only plain text
• POSSIBLE_WRAP_POINT - this type is used when we are dealing with possible wrap point
• WRAP_POINT - this type is used when we are dealing with "must-have" wrap point
• OPEN_TAG - this type says that we are dealing with opening html tag
• CLOSE_TAG - this type says that we are dealing with closing html tag
• PADDING - this type is used for certain paddings (e.g tab in the lists)
• BULLET - this type is used for indentifying bullet points in unordered lists
• ORDERING - this type is used for keeping ordering numbers from elements in ordered list

Tokenizer class

This is the class which main focus is simple parsing text in designated Tokens. Class has only one method tokenize(final String text, final WrappingFunction wrappingFunction). First argumen is text that we want to parse and the second argument is our well known wrapping function which determine how the text will be parsed.

TokenizerTest

Simple class with multiple JUnit tests as : testWrapPoints(), testSimpleItalic(), testBoldAndItalic() etc..

PipelineLayer class

Main focus of this class is to ensure correct "breaking" lines inside Paragraph depending on width. There is two usage of this class, as textInLine which represent a pipeline of current line text and sinceLastWrapPoint which represent a pipeline of text since last wrap point. We always iterate through many tokens and always calculating if we can add text since last wrap point to our current line text. You can view this also like this :

• textInLine - "safe" line text which will be certainly drawn
• sinceLastWrapPoint - line text since last wrap point which we want to add our current text in line if current width is not broken.

Supported tags :

• Bold,italic, bold-italic (<b>, </b>, <i>, </i>, <b><i></i></b>)
• Paragraph (<p></p>)
• Line break <br>, <br />
• Ordered/Unordered lists (<ol><li></li></ol>, <ul><li></li></ul>)

I'll try to find time to review this over the weekend, it looks nice and if I don't find any issues will merge it into the main branch.
