SEMI: convenient API for EMO recommendation

[Katya Garmash]

EMO = Extract Method Opportunity

Why

Currently, there is no implemented function that takes a method source code and directly output EMO recommendations. Such functionality could be useful to the end-used or if called by some refactoring plugin.

What we want

A function that takes a method declaration, and outputs SEMI recommendation in the form of an ordered list of recommended EMOs. The order is of decreasing recommendation. EMO is represented as a tuple (start_line_number, end_line_number).

def recommend(method_declaration_lines: List[str]): -> List[(int, int)]

Proposed solution

• Write a wrapper around existing functions extract_method_statements_semantic, create_extraction_opportunities,
  filter_extraction_opportunities, rank_extraction_opportunities
• implement it in a separate file under veniq.baseline.semi
