Conversion from (La)TeX to HTML

TeX and LaTeX are well suited to producing electronically publishable documents. However, it is important to realize the difference between page layout and functional markup. TeX is capable of extremely detailed page layout; HTML is not, because HTML is a functional markup language not a page layout language. HTML's exact rendering is not specified by the document that is published but is, to some degree, left to the discretion of the browser. If you require your readers to see an exact replication of what your document looks like to you, then you cannot use HTML and you must use some other publishing format such as PDF. That is true for any HTML authoring tool.

TeX's excellent mathematical capabilities remain a challenge in the business of conversion to HTML. Originally there were only two generally reliable techniques for generating mathematics on the web: creating bitmaps of bits of typesetting that can't be translated, and using symbols and table constructs. Neither technique is entirely satisfactory. Bitmaps lead to a profusion of tiny files, are slow to load, and are inaccessible to those with visual disabilities. The symbol fonts offer poor coverage of mathematics, and their use requires configuration of the browser.

Today, with native MathML rendering in some browsers and high quality math rendering available via JavaScript and CSS in all modern graphical browsers there are several possibilities.

The LaTeX to HTML convertors listed below all handle mathematics to some extent, and further math-specific details are discussed in Math on the Web.

For today, possible packages are:

- TeX4ht a compiled program that supports either

LaTeX or Plain TeX, by processing a DVI file; it uses
bitmaps for mathematics, but can also use other technologies where
appropriate.  Written by Eitan Gurari, it parses the DVI
file generated when you run (La)TeX over your file with
''tex4ht''s macros included.  As a result, it's pretty
robust against the macros you include in your document, and it's
also pretty fast. [[ctanpkg>tex4ht]].
Configuring and calling ''TeX4ht'' can be quite complicated,
Michal Hoftich's ''make4ht'' system provides an alternative
easier calling convention, using the ''tex4ht'' convertor internally.

- LaTeXML from NIST is a Perl program

that can parse most TeX code, including complicated macro definitions.
It was used for generating the web version of [[https://dlmf.nist.gov/|DLMF]]
from LaTeX sources. Currently it is distributed from the NIST site, and is not
in standard TeX distributions.

- lwarp by Brian Dunn is a recent TeX to HTML convertor that uses

 TeX to parse the input document. Documents may be produced by LaTeX, LuaLaTeX, or XeLaTeX.
 A texlua script removes the need for system utilities such as make and gawk,
 and also supports xindy and latexmk. [[ctanpkg>lwarp]].

- LaTeX2HTML a Perl script package that

supports LaTeX only, and generates mathematics (and other
"difficult" things) using bitmaps.  The original version was
written by Nikos Drakos for Unix systems, but the package now sports
an illustrious list of co-authors and is also available for Windows
systems.  Michel Goossens and Janne Saarela published a detailed
discussion of ''LaTeX2HTML'', and how to tailor it, in
TUGboat 16(2). [[ctanpkg>latex2html]].
A mailing list for users may be found via
[[https://tug.org/mailman/listinfo/latex2html|TUG]].

- Hevea a compiled program that supports LaTeX

only, and uses the font/table technique for equations (indeed its
entire approach is very similar to ''TtH'').  It is written
in Objective CAML by Luc Maranget.  ''Hevea'' isn't
archived on CTAN; details (including download points) are
available via [[http://pauillac.inria.fr/~maranget/hevea/|INRIA]].

- TtH a compiled program that supports either LaTeX

or Plain TeX, and uses the font/table technique for representing
mathematics.  It is written by Ian Hutchinson, using
''flex''.  The distribution consists of a single C
source (or a compiled executable), which is easy to install and very
fast-running. However the resulting HTML does not really reach
modern standards, and only very simple mathematics can be converted.

- plasTeX a Python-based LaTeX document processing

  framework.  It gives DOM-like access to a LaTeX document, as
  well as the ability to generate mulitple output formats
  (e.g. HTML, DocBook, tBook, etc.).

- TeXpider a commercial program from Micropress,

which is described on the [[http://www.micropress-inc.com/webb/wbstart.htm|Micropress web site]];
it uses bitmaps for equations.
