NAME

       goo, g2c - generic object-orientator (programming language)

SYNOPSIS

       goo
       g2c

DESCRIPTION

       This manual page documents briefly the goo and g2c commands.

       goo  and  g2c  interactively  evaluate  statements  in GOO, a dynamic, type-based, object-
       oriented language in the same family as Dylan and Scheme.  The language is designed to  be
       simple, productive, powerful, extensible, dynamic, efficient, and real-time.

       goo  and  g2c  support  two  evaluation  modes,  controlled  by  the  environment variable
       GOO_EVAL_MODE; the two commands differ only in which mode is the  default.   In  ast  mode
       (short  for  "abstract  syntax  tree",  and  the default for goo), they directly interpret
       parsed goo expressions.  In g2c  mode  (the  default  for  g2c),  they  instead  translate
       expressions into dynamically compiled C code.

OPTIONS

       None.

USAGE

       Typing goo or g2c at your shell will start up a goo read-eval-print loop, which accepts s-
       expressions and top-level commands commencing with a comma.  The following is  a  list  of
       available commands:

       ,quit  Exit the program.

       ^C (control-C)
              Invoke a recursive read-eval-print loop.

       ,g2c-eval
              Change to dynamic compilation evaluation.

       ,ast-eval
              Change to ast evaluation.

       ,in ,name
              Change to module name.

ENVIRONMENT

       GOO_EVAL_MODE
              Determines evaluation mode, as documented in DESCRIPTION above.

       GOO_ROOT
              Installation  root  (/usr  on Debian systems); files needed at runtime can be found
