@RUBY |
@RUBY[expression] : Returns the string result of the Ruby expression. Note that the Ruby environment is persistent within a TCC tab window, so you can do things like:
%@ruby[b = 42]
%@ruby[p b]
which will print "42". The value returned by @RUBY is the value returned by the RUBY API rb_eval_string.
You can query the type of the value returned by the last @RUBY call with the RUBYTYPE internal variable, and the value returned by the last @RUBY call with the RUBYVALUE internal variable.
