Experimental LaTeX3 High-Level Concepts
=======================================
2011/08/14
WHERE TO GET IT
---------------
The files in this distribution represent a snapshot of selected files
from the Subversion (SVN) repository of the LaTeX3 Project.
To obtain current versions of the files, visit
<http://www.latex-project.org/code.html> which contains further
instructions.
OVERVIEW
--------
The l3experimental packages are a collection of experimental implementations
for aspects of the LaTeX3 kernel, dealing with higher-level ideas such as the
Designer Interface. Some of them work as stand alone packages, providing new
functionality, and can be used on top of LaTeX2e with no changes to the
existing kernel. Others go further, and redefine LaTeX2e internals to provide
better methods for managing certain constructs. The packages in the collection
are under active development and the interfaces may change.
Currently included in the CTAN release of l3experimental are the following
bundles:
* xcoffins
xcoffins
--------
A _coffin_ is a 'box with handles': a data structure which comprises
both a TeX box and associated information to allow controlled typesetting.
The xcoffins package provides a high-level interface for manipulating
coffins. This is supported by the lower-level l3coffins package, which
provides the data structure.
xgalley
-------
In LaTeX3 terminology a galley is a rectangular area which receives
text and other material filling it from top. The vertically extend of
a galley is normally not restricted: instead certain chunks are taken
off the top of an already partially filled galley to form columns or
similar areas on a page. This process is typically asynchronous but
there are ways to control or change its behaviour. The xgalley module
provides a mechanism for filling galleys and controlling the spacing,
hyphenation and justification within them.
xfss
----
This package is a translation of LaTeX's font selection scheme into expl3.
Its primary utility is to provide font support when LaTeX3 is built as a
format, but in time features will be added that will make it useful in 2e
as well.
DISCUSSION
----------
Discussion concerning the approach, suggestions for improvements,
changes, additions, etc. should be addressed to the list LaTeX-L.
You can subscribe to this list by sending mail to
listserv@urz.uni-heidelberg.de
with the body containing
subscribe LATEX-L <Your-First-Name> <Your-Second-Name>
BUGS
----
The issue tracker for LaTeX3 bugs is currently located at
https://github.com/latex3/svn-mirror/issues
Please report specific issues with LaTeX3 code there. More general
discussion should be directed to the LaTeX-L lists.
