TRAILER: ANNOUNCING the Xy-pic version 2.12 DIAGRAM TYPESETTING PACKAGE
=======================================================================
Xy-pic is a package for typesetting a variety of graphs and diagrams
with TeX. Xy-pic works with most formats (including LaTeX, AMS-LaTeX,
AMS-TeX, and plain TeX; in particular Xy-pic is provided as a LaTeX2e
`package').
NOTE: version 2.12 is a (bug fix) final BETA CONFIDENCE TEST release
of Xy-pic 3 in the sense that it is likely to contain minor bugs in
both documentation and code but should be stable. If you are a user
of an earlier version of Xy-pic then PLEASE TEST this release with
your existing diagrams and REPORT PROBLEMS you encounter to the
authors!
The intention remains to maintain full backwards compatibility with
Xy-pic 2 but we need feed-back from users in order to achieve this
goal (see `The future and backwards compatibility' in the User's Guide
for the unavoidable exceptions).
Version 2.12 was the final result of the effort this springs to
outline Xy-pic 3 in collaboration with Ross Moore while visiting
Macquarie U, Sydney: The package is now structured as a kernel and
several orthogonal modules and several independent `specialist' modes
for convenient typesetting of Graphs and Trees, 2-cells, String and
braid diagrams, etc., are under construction.
Below I discuss the main features of Xy-pic and how it is available.
----------------------------------------------------------------------
VERSION 2.12 FEATURES
----------------------------------------------------------------------
Xy-pic version 2.12 provides four modes of specifying drawings that
can be combined:
* NEW: A polygon mode where diagrams shaped as regular polygons are
entered in a simple way.
* A graph combinator mode where diagrams are specified the way they
are composed as graphs.
* A matrix-like mode where the dimensions of the drawing are
automatically computed by aligning diagram entries in rows and
columns (this is also the `version 2 compatibility mode').
* A general `turtle graphic' drawing language for specifying graphs
with objects and connections between them in a manner independent of
orientation.
All modes support the following specific features:
+ Positions can be given in variety of formats (extendable) including
user defined coordinates (x,y) and relative to previous positions,
objects, object edges, and points on connections.
+ Objects may be circular or rectangular (more shapes can be added)
and adjusted in several ways.
+ Large library of objects with mnemonic names.
+ Objects that orient themself along a connection when placed relative
to it, e.g., `\dir{|-}' is like \vdash but thus oriented; new such
objects can be defined in a convenient way.
+ Includes circle segments and arbitrary TeX text.
+ Connections are aligned between the reference points of objects but
start and end on the edges.
+ Any object can be used to build a connection (using `diagonal
filling'); library objects provide common line types.
+ Special notation for drawing arrows with tail, stem, and head build
from any object(s). Special support for arrows that cross each
other, arrows that `go by' other entries, combined arrows, and
arrows with n/8 bends.
+ Library of frames.
+ Special notation for rotation, scaling, colour, and line thickness.
The correct typesetting of these features requires a backend that
supports it (i.e., PostScript) but even when this is not available
Xy-pic tries to approximate what is requested.
+ Output can use PostScript for drawing (several \special formats are
supported: dvips, dvitops, Textures, and OzTeX -- more are being
added continuously: contact Ross Moore <ross@mpce.mq.edu.au> for the
current list). Notation for inclusion of literal PostScript.
----------------------------------------------------------------------
AVAILABILTY
----------------------------------------------------------------------
Xy-pic can be retrieved by anonymous ftp from at least the following
locations (given as `site : directory'):
ftp.diku.dk : /diku/users/kris/TeX
ftp.mpce.mq.edu.au : /pub/maths/TeX
as well as (unpacked) on CTAN in macros/generic/diagrams/xypic.
The following distribution files should be available in the above two
locations but check the `README' file in each case (where the format
of the files is also explained):
