Dashed lines #10

Open martinthomson opened 2 years ago

martinthomson commented 2 years ago

At the same time as #9, it probably makes sense to look into support for dashed lines drawn with U+2506 and similar. There is already support for drawing them, just not recognizing them.

First of all Martin, this tool is already so incredibly slick. I have not been this excited about something at IETF in a very long time. IOU a beer at IETF 114. I am very interested in dashed and dotted lines. I'm guessing that there is a problem figuring out the semantics of period and colon characters, otherwise you could use those for horizontal and vertical dotted lines?

Yeah, the colons are easy. Replicating the logic for recognizing vertical lines should work out reasonably well, with some tweaks (+ might not be something we want to allow at end points, I don't know). Horizontal lines are tricky because period (.) is at the bottom of the box and there is a whole bit of logic that uses underscores for lines at the edge of the box. We might need to use middle dot (·) or the box art options (┄ or ┅).

Mostly this just needs time, something I don't have much of, even though I enjoy this sort of low-pressure coding.
