Help: Solve clipping of paragraphs. [Hard]

[PPartisan]

The "Help" page uses our markdown parser to convert paragraphs of markdown text into Lanterna widgets. This works but has a problem: individual widgets do not wrap their content but instead size themselves as a group to fit on a single page, meaning individual paragraphs can be cut off.

The simplest solution to this problem is to eliminate any custom formatting, treat all parsed Markdown as text, and place it inside a textbox. This would allow us to benefit from the scrolling behaviour of Lanterna textboxes, but it would also mean we lose our formatting (bold, italic, etc.).

Another more challenging option is to try to write our layout manager, which is scrollable so that all child widgets are sized to encompass all their content correctly.

I am happy with either solution, or any other solution, so long as all help text is visible in some form.

To replicate this problem, open the Help page in Roky. You'll notice that the second paragraph has had its text cut off at "apply the...", whereas the actual text continues (viewable here.

Solving the problem by taking the "hard" route will require the following steps:

• First, ensure that any widgets we load onto the page always resize to match their content, and not to match the bounds of the container (the Help page). For example, using the current markdown help text, the buttons should not be visible on the Help Page because the size of the content in the second paragraph is large enough to occupy the entire space on the page.
• Second, the container/layout manager needs to be able to detect whether or not the widgets it contains are too large to fit within its bounds. If this situation occurs, it should show a scrollbar and allow the user to scroll to view content outside the bounds of the container.
