- # Convenience method to create a new Inspector, using the given +inspect+
- # proc, and optional +init+ proc and passes them to Inspector.new
- #
- # irb(main):001:0> ins = IRB::Inspector(proc{ |v| "omg! #{v}" })
- # irb(main):001:0> IRB.CurrentContext.inspect_mode = ins # => omg! #<IRB::Inspector:0x007f46f7ba7d28>

- # An irb inspector
- #
- # In order to create your own custom inspector there are two things you
- # should be aware of:
- #
- # Inspector uses #inspect_value, or +inspect_proc+, for output of return values.
- #
- # This also allows for an optional #init+, or +init_proc+, which is called
- # when the inspector is activated.
- #
- # Knowing this, you can create a rudimentary inspector as follows:
- #
- # irb(main):001:0> ins = IRB::Inspector.new(proc{ |v| "omg! #{v}" })
- # irb(main):001:0> IRB.CurrentContext.inspect_mode = ins # => omg! #<IRB::Inspector:0x007f46f7ba7d28>
- # irb(main):001:0> "what?" #=> omg! what?
- #
- class Inspector
- # Default inspectors available to irb, this includes:
- #
- # +:pp+:: Using Kernel#pretty_inspect
- # +:yaml+:: Using YAML.dump
- # +:marshal+:: Using Marshal.dump
- INSPECTORS = {}
-
- # Determines the inspector to use where +inspector+ is one of the keys passed
- # during inspector definition.
- def self.keys_with_inspector(inspector)
- INSPECTORS.select{|k,v| v == inspector}.collect{|k, v| k}
- end
-
- # Example
- #
- # Inspector.def_inspector(key, init_p=nil){|v| v.inspect}
- # Inspector.def_inspector([key1,..], init_p=nil){|v| v.inspect}
- # Inspector.def_inspector(key, inspector)
- # Inspector.def_inspector([key1,...], inspector)
- def self.def_inspector(key, arg=nil, &block)
- if block_given?
- inspector = IRB::Inspector(block, arg)
- else
- inspector = arg
- end
-
- case key
- when Array
- for k in key
- def_inspector(k, inspector)
- end
- when Symbol
- INSPECTORS[key] = inspector
- INSPECTORS[key.to_s] = inspector
- when String
- INSPECTORS[key] = inspector
- INSPECTORS[key.intern] = inspector
- else
- INSPECTORS[key] = inspector

- # output return values in irb.
