troff2html – convert troff output into HTML|
troff2html [ −t title ] [ file ... ]|
Troff2html reads the troff(1) output in the named files, default
standard input, and converts them into HTML.
Troff2html does a tolerable job with straight troff output, but
it is helped by annotations, described below. Its main use is
for man2html (see Plan 9’s httpd(8)), which converts man(1) pages
into HTML and depends on a specially annotated set of man(7) macros,
invoked by troff −manhtml.
Troff output lines beginning|
which are introduced by placing \X'html ...' in the input, cause
the rest of the line to be interpolated into the HTML produced.
Several such lines are recognized specially by troff2html. The
most important are the pair
which are used to create HTML hyperlinks around text of the form
cp(1) pointing to /magic/man2html/1/cp.
Troff2html is new and experimental; in time, it may improve and
subsume Plan 9’s ms2html(1). On the one hand, because it uses
the input, ms2html can handle pic(1), eqn(1), etc., which troff2html
does not handle at all; on the other hand, ms2html understands
only ms(7) documents and is easily confused by complex troff constructions.
Troff2html has the reverse properties: it does not handle the
preprocessors but its output is reliable and (modulo helper annotations)
is independent of macro package.

Troff and HTML have different models, and they don’t mesh well
in all cases. Troff’s indented paragraphs are not well served
in HTML, and the output of troff2html shows this.|
