Wei wei@xcf.Berkeley.EDU Experimental Computing Facility (XCF) University of California, Berkeley CONTENT OVERVIEW OF THIS FILE - What is Viola - Copyright notice - Development status - Where to get Viola source and binaries - How to compile Viola - Running Viola - Where is the documentation - Viola mailing list ------------------------------------------------------------------------------- WHAT IS VIOLA Viola is basically a graphical user interface toolkit with an embedded command language. The interpretive nature of Viola enables it to be highly interactive: users can directly, or through scripts, create and modify objects without the tedious edit/compile/link/run cycle usually associated with GUI prototyping. COPYRIGHT Viola is available for the free public use. You may copy and use Viola for any purpose, as long as the copyright notice and permission in the sources are retained in all sources of derived works. Fees for distribution or use of this software or derived works may only be charged with express written permission of the copyright holder. DEVELOPMENT STATUS Viola is unofficially supported only by me, not by the Experimental Computing Facility. Also, since I'm graduating next month (May'91), Viola's future development is uncertain. I will, however, certainly continue to make efforts to maintain it. WHERE TO GET VIOLA Freely distributable source and binaries are available at ftp site scam.berkeley.edu (Internet 128.32.138.1). Look in directory "src/local/viola". Currently supported binaries were compiled on: DECstation 3100 (Ultrix T4.0-1) SparcStation (SunOS Release 4.0.3c) HOW TO COMPILE VIOLA Try using the binary before diving into a compile frenzy. Viola is written in plain C, uses X11R4 and has an mkmf Makefile. Just make sure the LIB_DIR and LIBNAME variables are correct. Viola can be installed anywhere in your path. RUNNING VIOLA You need to tell viola where to find the stack files. Also, since some stacks make use of man pages, you should set the MANPATH accordingly. Ie: % setenv MANPATH "${MANPATH}:/usr/local/lib/viola/man1" % setenv VIOLA "/usr/local/lib/viola/stacks" % /usr/local/bin/viola If viola executes and is able to find the default startup stacks, you should see a small icon-like window with two pull-down menus on it. temporary fix: if viola fails to start up, probably because it couldn't find the stacks, use the -option feature: % setenv MANPATH "${MANPATH}:/usr/local/lib/viola/man1" % /usr/local/bin/viola -objectFilePath "/usr/local/lib/viola/stacks" MAILING LIST I am very interested in your comments regarding all aspects of Viola -- bugs, design issues, application ideas, and stacks that you build. You can send comments to me by mailing to "wei@ic.berkeley.edu". There is a Viola mailing list "viola-users@ic.berkeley.edu". You can mail directly to the list, and if you wish to be on, or off, the list, let me know. ---------------------------------------------------------------------------- -- gerry pratt -- workstation support -- university of keele email: gerry@seq1.keele.ac.uk * tel: 0782 621111 x 3290 "these opinions are mine, mine, mine....ALL MINE I TELL YOU!"
