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


Source and binary can be found in
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.


You can send mail to Feedbacks, bug reports, patches,
constructive criticisms, etc, are always welcome.


In particular, many thanks to: Tim Bernners-Lee for inventing the WWW;
Tim and the CERN crew for the libwww; All the contributors on www-talk etc;
Jon Blow (ORA) for the lexical analyzer used in viola; Scott Silvey (ORA)
for creating the Motif front-end; Terry Allen (ORA) for lots of testings
and help with SGML; Dale Dougherty and Tim O'Reilly for supporting the
work on viola at ORA.
