The tools suite. This cluster contains all the main classes used to implement the following tools:

• clean
• compile
• compile_to_c
• compile_to_jvm
• finder
• pretty
• short

This cluster also provides many utilities used by the tools:

• ACE and CLUSTER provide for LACE features.
• BASE_CLASS represents a syntactic class, i.e. a tree of objects directly derived from a source by the Eiffel parser.
• E_FEATURE is the interface of the feature component. It represents a syntactic feature (attribute, command, query, once feature and so on) i.e. a tree of objects directly derived from a source by the Eiffel parser.
• E_TYPE is the interface of the e_type component. It represents an Eiffel type.
• EXPRESSION is the interface of the expression component. It represents an Eiffel expression, i.e. a syntactic construction having a result type.
• GLOBALS allows the tools to share singletons:
  • address_of_pool
  • ace
  • assignment_handler
  • constant_pool
  • cpp
  • echo
  • eiffel_parser
  • error_handler
  • frozen_string_list
  • gc_handler
  • id_provider
  • jvm
  • manifest_array_pool
  • method_info
  • once_manifest_string_pool
  • once_routine_pool
  • pretty_printer
  • smart_eiffel
  • string_aliaser
  • switch_collection
  • system_tools
• INSTRUCTION is the interface of the instruction component. It represents an Eiffel instruction.
• RUN_CLASS represents a live class, i.e. one to which some objects are assigned (either via creation, assignment or feature call). For example, ARRAY[INTEGER] and ARRAY[STRING] are two different RUN_CLASSes sharing the same BASE_CLASS.
• RUN_FEATURE represents a live feature, i.e. a callable feature tailored for some particular RUN_CLASS.
• SMART_EIFFEL manages the compilation process.
