 Starting RubyFORTH ====================== At the prompt, enter: ./rubyforth This command calls "ruby" by default. If your interpreter is stored as "ruby18", adjust this script. Running the (experimental) installation script, './install.sh': ./install.sh /usr/bin will generate a 'rubyforth' executable in the target directory. The script requires bash.  Command line arguments ========================== Everything following 'rubyforth' on the command line is evaluated as Forth code. As such, one can include files (see ) and process data before entering the outer interpreter. By terminating these arguments with 'bye', RubyFORTH can be called non-interactively from within shell scripts. NB: The words ." and " should be escaped on the command line: ./rubyforth .\" Welcome to RubyFORTH!\" cr will print "Welcome to RubyFORTH" at startup.  Including source ==================== From within RubyFORTH -- or on the command line -- both Ruby and Forth modules can be loaded. To load Forth source, enter either of the following: include <filename> needs <filename> replacing filename with the relevant path. 'needs' will only load 'filename' if it is not already loaded. Inclusion can be tested with: " <filename>" included? -- this will leave a flag on the stack. To load Ruby source, enter ruby-include <filename>  Tools ========= Some useful RubyFORTH scripts are located in the 'tools' directory of this distribution. If a script ends in '.rb', then include it with 'ruby-include' -- otherwise, use 'include' or 'needs'.  Semantics ============= For more information on the core vocabulary, please refer to the GLOSSARY document.  Compatability ================= RubyFORTH is known to work with Ruby 1.8.
