This week I spent some time investigating the possibility of having
spaces in filenames. The simple case is done, in that
\input "foo bar"
works about as well as you'd expect. The hard part is making sure
that (for example) LaTeX's
would also work. It turns out to be surprisingly hard to get this
right even in most cases, and then you need to tack on another bunch
on heuristics so that things like
cmr10 at 5pt
aren't interpreted as a single filename. I decided that it wasn't
worth the trouble and risk of introducing obscure bugs, so
is what you'll have to use in LaTeX. My conclusion is that if you
really want spaces in filenames in a natural manner, the current TeX
internals are the wrong place to start from.
I really admire Han The Thanh for doing pdfTeX with TeX as the
And I personally believe that this can be generalized: the algorithms
TeX uses for typesetting are still very good and useful. However, it
would be a mistake, IMAO, for a successor to TeX to be based on TeX's
internals. I'd like any such hypothetical system to be fairly
modular: a central typesetting core, with different front-ends for
various input languages (TeX's macro language, XML, ...) and different
back-ends for various output languages (PDF, PS, DVI, XML, ...). This
is why the actual NTS project was a bit of a disappointment to me.
