====== Conversion from (La)TeX to plain text ======


The aim here is to emulate the Unix ''nroff'', which formats
text as best it can for the screen, from the same
input as the Unix typesetting program ''troff''.

Converting DVI to plain text is the basis of many of these
techniques; sometimes the simple conversion provides a good enough
response.  Options are:
  * ''dvi2tty'' (one of the earliest),
  * ''crudetype'' and
  * ''catdvi'', which is capable of generating Latin-1 (ISO 8859-1) or UTF-8 encoded output.  ''Catdvi'' was conceived as a replacement for ''dvi2tty'', but development seems to have stopped before the authors were willing to declare the work complete.

A common problem is the hyphenation that TeX inserts when typesetting
something: since the output is inevitably viewed using fonts that don't
match the original, the hyphenation usually looks silly.

Ralph Droms provides a [[ctanpkg>txt|txt]] bundle of things in support of
ASCII generation, but it doesn't do a good job with tables and mathematics.

Another possibility is to use the LaTeX-to-ASCII conversion program,
[[ctanpkg>l2a]], although this is really more of a de-TeXing program.

The canonical de-TeXing program is ''detex'', which removes
all comments and control sequences 
from its input before writing it to its output.  Its original purpose
was to prepare input for a dumb spelling checker, and it's only usable
for preparing useful ASCII versions of a document in highly
restricted circumstances.

''Tex2mail'' is slightly more than a de-TeXer --- it's a
Perl script that converts TeX files into
plain text files, expanding various mathematical symbols
(sums, products, integrals, sub/superscripts, fractions, square
roots, ...) into "ASCII art" that spreads over
multiple lines if necessary. The result is more readable to human
beings than the flat-style TeX code.

Another significant possibility is to use one of the
[[FAQ-LaTeX2HTML|HTML-generation solutions]],
and then to use a browser such as ''lynx'' to dump the resulting
HTML as plain text.
