Transcript

1. Automated Program Transformation with srcML and LINQ Vinay Augustine, Ph.D.
2. Overview ƒ ABB Corporate Research ƒ The Problem ƒ The Solution ƒ What is srcML? ƒ What is LINQ? ƒ Demonstration ƒ Questions
3. ABB Corporate Research Industrial Software Systems (ISS) • USA • Germany • Switzerland • Poland • Sweden • India • China 7 research centers worldwide Raleigh, NC
4. Software at ABB What motivates us? Embedded Software Software / Hardware Hybrids 100% Software
5. Adaptive Maintenance Changes The Problem Month DD, Year | Slide 5 © ABB Group The Scenario ƒ Long-lived legacy software ƒ Adapt source code for new ƒ Compilers ƒ Libraries ƒ Environments
6. The Scenario ƒ Long-lived legacy software ƒ Adapt source code for new ƒ Compilers ƒ Libraries ƒ Environments Resulting Issues • Time-consuming • Error-prone • Repetitive Adaptive Maintenance Changes The Problem Month DD, Year | Slide 6 © ABB Group
7. Adaptive Maintenance Changes An Example Month DD, Year | Slide 7 © ABB Group Source: http://msdn.microsoft.com/en-US/library/vstudio/h4bcz65t(v=vs.80).aspx
8. Our Solution ƒ Lightweight ƒ Multi-language ƒ Easy to test ƒ Fast ƒ Familiar to developers Month DD, Year | Slide 8 © ABB Group srcML (fast!) + LINQ (familiar!)
9. ƒ What is it? ƒ XML annotation for source code ƒ Why do we like it? ƒ Adds structure to source code ƒ Multilanguage ƒ Fast! ƒ Remove it to get original source! What is srcML? (and why do we like it?) Month DD, Year | Slide 9 © ABB Group Source: http://www.sdml.info/projects/srcml/
10. ƒ Provides SQL-like queries for C# ƒ Extensive IDE support in Visual Studio ƒ Natural for developers ƒ Can query XML LINQ Language INtegrated Query
11. Automate an adaptive maintenance change on real software Wrap all uses of “new” with a try/catch block in Demonstration Month DD, Year | Slide 11 © ABB Group Source: http://notepad-plus-plus.org/news/notepad-6.2-release-udl2.html
12. Demonstration 1. Learn about “new” in srcML 2. Where is “new” used? 3. Find all expressions that use “new” 4. Transform all “new” expressions 5. Execute the transform 6. Run the new notepad++.exe Steps Month DD, Year | Slide 12 © ABB Group
13. Questions? Automated Program Transformation with srcML + LINQ ƒ Fast ƒ Multi-language ƒ Easy to test Go to our github page for • more information • the code • and this demonstration http://github.com/abb-iss/SrcML.NET Month DD, Year | Slide 13 © ABB Group
