Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(method, *args, &block) ⇒ Object

Only works for attribute fetches, setting is no longer supported XXX: this should be deprecated

#run_contextObject

RunContext will set itself as run_context via this setter when initialized. This is needed so DSL::IncludeAttribute (in particular, #include_recipe) can access the run_context to determine if an attributes file has been seen yet. – TODO: This is a pretty ugly way to solve that problem.

#consume_chef_environment(attrs) ⇒ Object

chef_environment when set in -j JSON will take precedence over -E ENVIRONMENT. Ideally, IMO, the order of precedence should be (lowest to

highest):
 config_file
 -j JSON
 -E ENVIRONMENT

so that users could reuse their JSON and override the chef_environment configured within it with -E ENVIRONMENT. Because command line options are merged with Chef::Config there is currently no way to distinguish between an environment set via config from an environment set via command line.

Returns the fully-expanded list of recipes, a RunListExpansion.

– TODO: timh/cw, 5-14-2010: Should this method exist? Should we instead modify default_attrs and override_attrs whenever our run_list is mutated? Or perhaps do something smarter like on-demand generation of default_attrs and override_attrs, invalidated only when run_list is mutated?

#recipe?(recipe_name) ⇒ Boolean

Returns true if this Node expects a given recipe, false if not.

First, the run list is consulted to see whether the recipe is explicitly included. If it's not there, it looks in `node`, which is populated when the run_list is expanded

NOTE: It's used by cookbook authors
