# File lib/pry/commands/show_source.rb, line 48 def content_for(code_object) content = '' if opts.present?(:d) code = Code.new( render_doc_markup_for(code_object), start_line_for(code_object), :text ) content += code.with_line_numbers(use_line_numbers?).to_s content += "\n" end code = Code.new( code_object.source || [], start_line_for(code_object) ) content += code.with_line_numbers(use_line_numbers?).highlighted content end
docs_for(code_object)
click to toggle source
Return docs for the code_object, adjusting for whether the code_object has yard docs available, in which case it returns those. (note we only have to check yard docs for modules since they can have multiple docs, but methods can only be doc'd once so we dont need to check them)
# File lib/pry/commands/show_source.rb, line 86 def docs_for(code_object) if code_object.module_with_yard_docs? # yard docs code_object.yard_doc else # normal docs (i.e comments above method/module/command) code_object.doc end end
