As a follow up of my flood algorithm question, I have worked today on drawing 2D lines that can only have a horizontal segment and a vertical one. The longest segment is the major one, drawn first, and a minor segment follows.
I’ve managed to code something and it checks against all of my examples, but it’s pretty long and convoluted (~ 60 lines of elm-formatted code for the toRectLine function). Would anyone have something to suggest for efficiency?
No worries if you don’t have time to check it out. I tried to add comments to everything ambiguous but it’s pretty long with the examples and all.
Thanks to the people who had a lightning-fast answer yesterday, the community is pretty cool around here 
EDIT: did not work in practice so here is a (so far) working example even longer and more convoluted
