Hi all
I noticed that in Solaris 10, troff itself eqn tbl are there, but I
still need pic, please tell me where can I get this? package or
source code are both ok.
By coincidence, I just stumbled across http://
heirloom.sourceforge.net/ which among other things includes "portable
and enhanced versions of the utilities released by Sun as part of
OpenSolaris"
They seem to have added:
* “Plug-and-Play” font handling: troff can access PostScript
Type 1, OpenType, and TrueType fonts directly, that is, it can read
font metrics from AFM, OpenType, or TrueType files, and can instruct
its dpost post-processor to include glyph data from PFB, PFA,
OpenType, and TrueType files into the output it generates.
* Justification improvements include paragraph-at-once
adjustment using a variant of the Knuth-Plass algorithm originally
developed for TeX, and options to decrease word spaces and to
dynamically change the letter spacing as well as the glyph widths
(microtypography).
* Pairwise kerning of characters and letter space tracking are
supported. troff includes a request to construct kerning pairs for
characters from different fonts.
* Hanging characters can be used, for example, hyphens can
partially or entirely hang over the right margin of a document.
* Mechanisms for typesetting small capitals, old-style numerals,
and arbitrary ligatures e.g. using Type 1 “expert” or OpenType fonts
are provided.
* Letters can be of arbitrary size, including fractional point
sizes. Individual fonts can be zoomed.
* Text input is processed according to the LC_CTYPE environment
variable. With a UTF-8 locale, a large set of characters is available
without the need to type troff escape sequences.
* Hyphenation of international languages is supported using the
OpenOffice variant of Raph Levien's LibHnj, which is in turn based on
Liang's TeX algorithm.
* International paper sizes such as A4 can be configured.
* The dpost post-processor can generate instructions for the PDF
distiller for the inclusion of bookmarks, links, titles, and
authorship information.
* Most groff extensions, like long names for requests, strings,
and number registers, are supported. A special groff compatibility
mode is also provided.
* Other troff language extensions include a string search
request, output line traps, floating-point registers, and local
variables per macro instance.
