If you have used Hyperlatex 1.3 before, then you may be surprised by this new version of Hyperlatex. A number of things have changed in an incompatible way. In this section we'll go through them to make the transition easier. (See below for an easy way to use your old input files with Hyperlatex 1.4 and 2.0.)
You may wonder why those incompatible changes were made. The reason is that I wrote the first version of Hyperlatex purely for personal use (to write the Ipe manual), and didn't spent much care on some design decisions that were not important for my application. In particular, there were a few ideosyncrasies that stem from Hyperlatex's origin in the Emacs latexinfo package. As there seem to be more and more Hyperlatex users all over the world, I decided that it was time to do things properly. I realize that this is a burden to everyone who is already using Hyperlatex 1.3, but think of the new users who will find Hyperlatex so much more familiar and consistent.
\NotSpecial that allows you to
turn off a special character, if you use it very often.
The treatment of special characters was really a historic relict
from the latexinfo macros that I used to write Hyperlatex.
latexinfo has only three special characters, namely \,
{, and }. (latexinfo is mainly used for software
documentation, where one often has to use these characters without
their special meaning, and since there is no math mode in info
files, most of them are useless anyway.)
\W (instead of \H).
The old command \H redefined the LaTeX command for the Hungarian
accent. This was really an oversight, as this manual even
shows an example using that accent!
\+, \=, \S, \C,
\minus, \sim ... are no longer recognized by
Hyperlatex 1.4.
It feels wrong to deviate from LaTeX without any reason. You can easily define these commands yourself, if you use them (see below).
\htmlmathitalics command has disappeared (it's now the
default)
example environment, only the four
characters %, \, {, and } are special.
In Hyperlatex 1.3, the ~ was special as well, to be more
consistent. The new behavior seems more consistent with having ten
special characters.
\set and \clear commands have been removed, and their
function has been taken over by
\newcommand.
Most of your files that you used to process with Hyperlatex 1.3 will
probably not work with newer versions of Hyperlatex immediately. To
make the transition easier, you can include the following declarations
in the preamble of your document (or even in your init.hlx
file). These declarations make Hyperlatex behave very much like
Hyperlatex 1.3--only five special characters, the control sequences
\C, \H, and \S, \set and \clear are defined, and so are
the small commands that have disappeared. If you need only some
features of Hyperlatex 1.3, pick them and copy them into your
preamble.
