-*-text-*- Description =========== Sizzle is a interpreter for the Scheme programming language. It is mainly designed for being embedded into applications written in C, where it can be used for parsing configuration files and as an extension language. Right now, Sizzle only implements a subset of the Scheme as defined in the "Revised^5 Report on the Algorithmic Language Scheme" (R5RS), but it is sufficient for using it as an extension language and for scripting tasks. It has been successfully been used for text processing and for writing a simple web server in Scheme (which can be found in the subdirectory `examples'). Sizzle is currently used in the `Serveez' network server framework, where it parses the configuration files. I also use Sizzle as the extension language in my window manager `wimpwm'. If you need a more sophisticated Scheme interpreter (with threads, proper call/cc etc.), then have a look at Guile, available from <http://www.gnu.org/software/guile/>. Installation ============ For more information on installing the package, please consult the file INSTALL, included in this distribution. Short instructions: tar xzvf sizzle-<version>.tar.gz cd sizzle-<version> ./configure make su -c 'make install' Usage ===== Just type `sizzle' at the command prompt, and the interpreter starts in the interactive mode. There you can enter Scheme expressions and see how they evaluate. $ sizzle zzz: (+ 1 2) 3 zzz: (exit) $ You can stop the interpreter by pressing ^D (control-d) or typing `(exit)' at the prompt. Another method is to run Sizzle for evalutating text files containing Scheme source code. Given a file `hello.scm' with the following contents: -- hello.scm start -- (display "Hello World!") (newline) -- hello.scm end -- you can do this: $ sizzle -s hello.scm Hello World! $ Deinstallation ============== Change to the directory where you built Sizzle, and type the following su -c 'make uninstall' Documentation ============= The file INSTALL contains information about the installation process. The file NEWS documents the changes to the current release. For more information, have a look at the doc directory. The reference manual is in the file `sizzle-ref.info', and the embedding manual in the file `sizzle-embed.info'. Have fun, 'mgrabmue
