|
|
185 Here is information on RosettaMan, from Neal.Becker@comsat.com (Neal Becker):
|
|
|
186
|
|
|
187 RosettaMan is a filter for UNIX manual pages. It takes as input man
|
|
|
188 pages formatted for a variety of UNIX flavors (not [tn]roff source)
|
|
|
189 and produces as output a variety of file formats. Currently
|
|
|
190 RosettaMan accepts man pages as formatted by the following flavors of
|
|
|
191 UNIX: Hewlett-Packard HP-UX, AT&T System V, SunOS, Sun Solaris, OSF/1,
|
|
|
192 DEC Ultrix, SGI IRIX, Linux, SCO; and produces output for the following
|
|
|
193 formats: printable ASCII only (stripping page headers and footers),
|
|
|
194 section and subsection headers only, TkMan, [tn]roff, Ensemble, RTF,
|
|
|
195 SGML (soon--I finally found a DTD), HTML, MIME, LaTeX, LaTeX 2e, Perl 5's pod.
|
|
|
196
|
|
|
197 RosettaMan improves on other man page filters in several ways: (1) its
|
|
|
198 analysis recognizes the structural pieces of man pages, enabling high
|
|
|
199 quality output, (2) its modular structure permits easy augmentation of
|
|
|
200 output formats, (3) it accepts man pages formatted with the varient
|
|
|
201 macros of many different flavors of UNIX, and (4) it doesn't require
|
|
|
202 modification or cooperation with any other program.
|
|
|
203
|
|
|
204 RosettaMan is a rewrite of TkMan's man page filter, called bs2tk. (If
|
|
|
205 you haven't heard about TkMan, a hypertext man page browser, you
|
|
|
206 should grab it via anonymous ftp from ftp.cs.berkeley.edu:
|
|
|
207 /ucb/people/phelps/tkman.tar.Z.) Whereas bs2tk generated output only for
|
|
|
208 TkMan, RosettaMan generalizes the process so that the analysis can be
|
|
|
209 leveraged to new output formats. A single analysis engine recognizes
|
|
|
210 section heads, subsection heads, body text, lists, references to other
|
|
|
211 man pages, boldface, italics, bold italics, special characters (like
|
|
|
212 bullets), tables (to a degree) and strips out page headers and
|
|
|
213 footers. The engine sends signals to the selected output functions so
|
|
|
214 that an enhancement in the engine improves the quality of output of
|
|
|
215 all of them. Output format functions are easy to add, and thus far
|
|
|
216 average about about 75 lines of C code each.

220 *** NOTES ON CURRENT VERSION ***
|
|
|
221
|
|
|
222 Help! I'm looking for people to help with the following projects.
|
|
|
223 \(1) Better RTF output format. The current one works, but could be
|
|
|
224 made better. (2) Roff macros that produce text that is easily
|
|
|
225 parsable. RosettaMan handles a great variety, but some things, like
|
|
|
226 H-P's tables, are intractable. If you write an output format or
|
|
|
227 otherwise improve RosettaMan, please send in your code so that I may
|
|
|
228 share the wealth in future releases.
|
|
|
229
|
|
|
230 This version can try to identify tables (turn this on with the -T
|
|
|
231 switch) by looking for lines with a large amount of interword spacing,
|
|
|
232 reasoning that this is space between columns of a table. This
|
|
|
233 heuristic doesn't always work and sometimes misidentifies ordinary
|
|
|
234 text as tables. In general I think it is impossible to perfectly
|
|
|
235 identify tables from nroff formatted text. However, I do think the
|
|
|
236 heuristics can be tuned, so if you have a collection of manual pages
|
|
|
237 with unrecognized tables, send me the lot, in formatted form (i.e.,
|
|
|
238 after formatting with nroff -man), and uuencode them to preserve the
|
|
|
239 control characters. Better, if you can think of heuristics that
|
|
|
240 distinguish tables from ordinary text, I'd like to hear them.
|
|

|
|

244 parsing--no <PRE>! Man page references are turned into hypertext links.")
