Instance Method Details

#execute(argv = nil, input: $stdin, out: $stdout) ⇒ Object

Execute some campa stuff depending on the options given in the command line.

If no argument is given it will start a Repl session.

When first argument is an existent file then it will evaluated using Reader and Evaler.

If the CLI argument is anything else, this method tries to match it with OPTIONS and find the method to be executed. Current options for the CLI are:

campa test FILE1, FILE2 Uses Campa::Core::Test and Campa::Core::TestReport to evaluate the files given as options as Campa test code.
