line feeds in proofs

[davidfarmer]

Is this legal in MBX?

<title>Base Case:</title>Draw a tree with three vertices. Clearly you have only 2 edges (otherwise you would have a cycle)

I don't understand your second comment about legality, but I think I have an answer to your original question.

In the LaTeX code, I used the double backslash to create new lines purely for the sake of presentation (to avoid overful boxes, for example), and as a cheap way to create a list (without bullets, for example as I did in the answer to question 5 of section 5.5 (in the web version).

I don't use this primarily in proofs, although it is almost always in proofs, examples, exercises and answers. So really anything where I might need to display things not in regular sized paragraphs.

Perhaps the most reasonable approach to this would be to treat each occurrence as a paragraph break. So if it occurs inside a paragraph, then replacing the double backslash with </p> <p> should work. Outside of paragraphs (like inside a <li>) I don't really know what the best approach would be. Can you have paragraphs inside list items? If so, that would work, but it would require backtracking to the start of the line to add a <p> element, and then adding a </p> at the end of the line.

This does not take care of the instances where I put the backslashes to fix formating bugs, but those should be fairly rare and easy to spot and fix in the mbx code.

I will try replacing all double backslashes in text by double
line feeds. I should be able to do that after all the environments
are separated (so I know which blocks are math and can leave them
alone) but before I break into paragraphs.

MBX should (or does or will) have markup for "cases"
in a proof, which you will have to add by hand.
