Text wrapping

[jacobrosenthal]

For #9

This scrolling issue around paragraph seems related fdehau/tui-rs#89
It put me onto just wrapping before giving text to tui list widget.

Allows to not use paragraph at all, and keep using list.

However.. hard to get access to terminal width, which could change dynamically, inside the rtt polling.

Could instead not do any formatting in channel and do it all in app.rs but then hard to do timestamps.

Even with something like this we still need some kind of vertical scrolling solution or were still just losing data above now
fdehau/tui-rs#61

Thoughts?

I will try this at home. Thanks for submitting this :)
Actually I prefer this to horizontal scrolling.

Imo the entire scrolling game is a pain anyways because how do you select text over more lines than the screen fits? I oftentime want to select text. That's why I want a dedicated UI client :) Also, maybe we should implement dumping into a file.

Added another take...This might be a decent first step while we help patch the upstream widgets. Though note pgup scrolling was broken

[jacobrosenthal]

Theres probably performance concerns with long running processes, but they seem outweighed by not being able to see output of screen on short running processes which are far more common.

Sadly it still wraps after the timestamps :) I am pretty sure the wrap lib you introduced tries to wrap at spaces first :)

[jacobrosenthal]

This is master branch behaviour. split_terminator destroys all new lines, so newlines inside debug statements are added as new timestamps.

I guess we can merge this now and fix the bad allocations and weird line break after the timestamps later on :)
