The new ViolaWWW is now available for ftp'ing. It's beta and feedback
is very welcomed. The README file follows...
===========================================================================
ViolaWWW, Version 3.0 Beta Feb 23 1994
==========================
ViolaWWW is an extensible World Wide Web hypermedia browser for XWindows.
Based on and drawing from the Viola scripting language and toolkit,
ViolaWWW provides a way to build relatively complex hypermedia applications
that are beyond the provisions of the current HTML standard.
Notable features in the new ViolaWWW
------------------------------------
* HTML+ support: container paragraphs; input forms; tables.
(Note: not yet exact and complete compliance with the currently
evolving HTML+ standard)
* In addition to the currently defined HTML+, there're a few other
extensions, such as for columning and document insertion (client side).
* Embeddable in-document and in-toolbar programmable viola objects.
A document can embed mini viola applications (ie: a chess board),
or can cause mini apps to be placed in the toolbar.
* Motif front-end. The X11 (non Motif) version is also available.
* Single binary for easy installation, unlike the old ViolaWWW which
required setup of various viola application files.
Availability
------------
Source and binary can be found in ftp://ora.com/pub/www/viola.
Sparc binary is supplied.
I'd appreciate hearing about compilation success stories (and patches)
for platforms other than SunOS and Ultrix.
Compiling and running ViolaWWW
------------------------------
To compile, run the 'BUILD' script (or 'BUILD.decstation').
This generate two binaries: viola/src/viola/viola and viola/src/vw/vw.
Right now, you should use the binary 'vw' as it is the ViolaWWW with
the Motif GUI, which is currently the more polished front-end.
But do let us know if you'd like support on the non Motif version.
Note: Viola requires X11R5, and the Motif version of ViolaWWW requires
a Motif toolkit library. The libwww(2.14) that comes with ViolaWWW is
modified, so until the changes are integrated into CERN's, don't use
the libwww that didn't come with viola.
