Abstrakčios sintaksės medžių pertvarkymo algoritmų tyrimas / Investigation of Refactoring Algorithms for Abstract Syntax Tree

Jokubauskas, Justas 25 August 2010 (has links)
Per pastaruosius metus, lankstaus programavimo metodikos sulaukė daug dėmesio. Programų kodo pertvarkymas tapo viena iš labiausiai naudojamų praktikų, ypač ekstremaliame programavime. Todėl poreikis turėti programos kodo pertvarkymų įrankį išaugo iki tokio lygio, kad pertvarkymo įrankiai tapo reikalaujama priemone šiuolaikinėse programų kūrimo aplinkose. Tyrimo sritis – abstrakčios sintaksės medžių pertvarkymo algoritmai. Tyrimo objektas – abstrakčios sintaksės medžių pertvarkymo procesai skirtingose programavimo kalbose (C++ ir Java). Šio darbo tikslas – ištirti, kaip efektyviai būtų galima vykdyti pertvarkymus bendriniam AST, tam sukuriant pertvarkymų biblioteką ir atliekant eksperimentus įvairių kalbų atvejais. / Over the past years, agile development methodologies have attracted a lot of attention. Refactoring has become one of the most heavily used practices, especially in Extreme Programming. Therefore the need to have powerful refactoring tools has grown to such an extent, that there is a required feature for modern-day IDEs to have implemented refactoring tools. The aim of this work is to build a refactoring library for the generic abstract syntax tree and test the algorithms for speed. Generic abstract syntax tree (GAST) is a tree structure that can store elements of several programming language. Achieving this goal required doing certain tasks that you find in this document: analysis of technologies and existing software; several algorithms for refactoring; user need and specification of requirements; library model, expressed in UML diagrams; test plan and test procedure. Experiments have shown that it is necessary to improve the refactoring algorithms. But the library and the AST structure is worth further development.
