Class Method Details

.cmdline ⇒ Object

cmdline is an instance of Cmdline::Parser that represents the arguments that were passed via the commandline. It handles parsing those arguments, and choosing the task to perform based on the ‘verb’ supplied - e.g. ‘meet’, ‘list’, etc.

  end
end

.run ⇒ Object

The top-level entry point for babushka runs invoked at the command line. When the babushka command is run, bin/babushka.rb first triggers a load via lib/babushka.rb, and then calls this method.

end

.sources ⇒ Object

sources is an instance of Babushka::SourcePool, contains all the sources that babushka can currently load deps from. This means all the sources found in ~/.babushka/sources, plus the default sources:

- anonymous (no source file; i.e. deps defined in an +irb+ session,
  or similar)
- core (the builtin deps that babushka uses to install itself)
- current dir (the contents of ./babushka-deps)
- personal (the contents of ~/.babushka/deps)

.task ⇒ Object

task represents the overall job that is being run, and things that are external to running the corresponding dep tree itself, like logging.
