The hyperlatex-in-paragraph flag I introduced is not, however, the

But the real problem is that the hyperlatex parser design and HTML
semantics are fundamentally different than the TeX parser design and
LaTeX semantics.
During the weekend I'll think on getting HypperLatex
closer to TeX in the way it parses input to recognize paragraph
borders. We should follow Knuth's approach in which vertical and
horizontal modes, vertical lists and other notions have been
introduced and are used for the purpose.
The uncertainty is made more acute for two reasons. One is that
there is a wide variety of browsers out there and they all seem to
differ about what is good html.
That's right. TeX's semantics has been defined precisely in
the program of TeX. There is no formal semantics of HTML.
Its RFC is imprecise, mostly because it's expressed
a natural language. Thus, the authors of browsers have
some freedom in understanding it.
I'd also like to change the way Hyperlatex writes its output right
into the same buffer as it's getting its input. This makes the second
pass pretty confusing, requires that a substantial number of macros
are interpreted twice in exactly the same way, which seems
inefficient, and requires protecting characters in such a way that
dealing with alternate character sets in a robust way is difficult.
But this is also a substantial task, and there may be design issues I
don't know about that dictated this choice in the first place.
I agree. It strikes me that everything in HyperLatex
-- reading and writing -- happens in just one buffer. Should it be
not Emacs I would first convert the input to some well-defined internal
structure, that is to an abstract syntax tree, and then inteprete
the tree in order to generate output. I have successfully applied
such an approach in a few Haskell programs that analyse XML
documents and generate TeX code. Emacs LISP, though, is not equipped
with such a nice system of types as Haskell is...
I want to concentrate on the paragraphs first. I hope to come with
new ideas after the weekend.
