man2html - convert a UNIX manual page file from nroff/troff -man format to HTML
man2html [ -check-html ] [ -grammar-level grammar ] [ -outdirectory directoryname ] [ -prettyprint ] [ -split-limit filesize-in-bytes ] input-manpage-file(s)
man2html converts UNIX manual page files named on the command line, from nroff (1)/ troff (1) -man format to strictly-grammar-conforming HTML.
The output files have the same base name (or the base name with a numeric suffix, if output HTML file splitting is requested), but extension .html.
Although some vendors, such as Sun Microsystems, provide clear documentation of how manual pages should be written, many manual page authors ignore those recommendations, and use arbitrary [ nt ] roff markup to achieve the traditional appearance of UNIX manual pages, without actually using the standard -man format commands.
man2html works quite well on Sun manual pages, but may be less successful on manual pages from other sources. In such a case, an alternative may be to use T. A. Phelp's RosettaMan (1), commonly installed as rman (1). That program works on the output of nroff (1), and attempts to guess manual page structure from the horizontal and vertical spacing in order to add HTML markup. When vendor-provided manual pages are available only in preformatted form, as on IBM AIX and SGI IRIX systems, rman (1) may be your only choice. However, when man2html can be used successfully, it can often do a better job than rman (1), because it has a better understanding of the document structure implied by [ nt ] roff manual-page markup.
Command-line options may be abbreviated to any unique prefix, and letter case is significant. Options and files are processed in the order found; thus, options affect only files that follow them on the command line.
<!DOCTYPE HTML PUBLIC "...">
declaration. Acceptable values are: 0, 1, 2, 2-strict, 3 , 3-strict, 3.2, 4, 4-loose, Cougar, Mosaic, and Netscape [default: 2 ].
The root file will contain a table of contents that directs the reader to the section files, and each of those begins and ends with a navigation command area that allows moving one to three sections in either direction, as well as back up to the root file.
This option permits large manual page files to be split into smaller parts that load faster over the World-Wide Web, although with the possibly significant disadvantage that the reader can no longer search the entire document with a single command.
The level 3 grammar has expired; some of its features, particularly the support for markup of mathematics, will appear in a future HTML grammar level.
The version 3.2 grammar is a stopgap, which, despite its higher number, lies approximately between 2 and 3 in features. It was released on November 5, 1996, at http://www.w3.org/pub/WWW/ in order to provide a stable grammar toward which WWW browser developers could work.
The next version of HTML, code-named Cougar, is under development, and will become version 4.0 when it is finally released. The first draft public release was on 8 July 1997, and that was followed by a proposed recommended version on 7 November 1997.
There are only four potential differences in the output of man2html for these grammar levels:
- The output <!DOCTYPE HTML PUBLIC "... "> declaration depends on the grammar level.
- At version 3 and above, the SGML entity & nbsp; can be used for non-breakable space instead of the less obvious numeric entity & #160; which is required by the level 2 grammar.
- At versions 3 and 3.2, the SGML entity & quot;, representing a quotation mark, must be replaced by a numeric entity, ", because of an unfortunate error of omission in the grammars.
- At version 3.2 and higher, the output HTML will use <CENTER> ... </CENTER> directives to support centered text. At earlier grammar levels, centering requests are ignored, but the request is preserved in a comment, and lines are still broken as they would be when centered.
Centering is exceedingly rare in manual page files (it is completely absent from all of Sun's standard manual pages), so the default level 2 grammar should almost always be sufficient.
