Markdown parser part 2

The markdown parser is kind of going according to plan. I realised that with the appoach I decided to take I'm going to need a couple of more steps than just going line by line and deciding what type of element each should be.

Let's take an example:

Some **bold** text and then some _cursive_ text

This is not only a text line but it has both bold and cursive text.

So in addition to parsing the markdown files line by line (stage 1), I implemented stage 2 processing with the purpose of expanding the identified elements into child elements. So when a text row element containing the text in the example above is requested to peform its stage 2 processing it will take its text and run it once more through the stage 1 processing to divide it into new symbols. It then calls stage 2 processing of all its new children to make sure every element has been processed.

In the end we should have gone from TextLine to PlainText, Bold, PlainText , Italic, Plaintext.

Here's the result.

Some bold text and then some cursive text

Next up is stage 3 processing which will affect elements depending on their position in the list of elements.
