GtkMathView v0.1.0 Announcement
-------------------------------
I'm glad to announce the first release of GtkMathView, a GTK widget
for rendering MathML documents. It is meant to be a standalone,
light-weight component and not a full browser. GTK applications can
use the widget as a window for displaying mathematical formulas and
doing simple interactions.
At present, the widget is actively used as part of the HELM project
(see http://www.cs.unibo.it/helm).
This is both an announcement and a call for contribution. Despite the
low-numbered version, the widget recognizes most of MathML 2 (Draft)
elements and attributes (actually, only the handling of labeled rows
in a table is missing). Here are some of the features of GtkMathView:
- breaking of long expressions
- support for stretchy operators
- configurable support for additional fonts
- configurable support for the operator dictionary
- configurable support for entities
- selection of MathML subtrees
However, the code is far from being heavily tested, and I think there
are many bugs. For these reasons, anyone interested can contribute
with bug reports, suggestions and active development of the code, the
documentation, the configuration scripts. With your support, I expect
to release the 1.0 version in a few weeks.
Here is the home-page of the widget:
http://www.cs.unibo.it/~lpadovan/mml-widget/
You will find the source package and the online version of the manual
(included in the distribution). The package includes detailed
information for compiling and running the widget, as well as the
source code of a minimal browser and some (sample) configuration
files.
To test the widget, write a MathML document (simply enclose a MathML
expression within a <math> element) and run the minimal browser on it.
(See at the bottom of this file for an example).
A note about the license: the widget is covered by the GNU GPL license
(NOT the GNU LGPL).
Waiting for your feedback,
Luca Padovani <luca.padovani@cs.unibo.it>
