Does anybody know a fully featured refactoring tool for C that works reliably with large code bases (some 100.000 lines)? I tried whatever i can find again and again over the last years: SlickEdit, Eclipse CDT. They all were not at all usable. SUMMARY: I took time and evaluated 'Visual Assist X' as well as 'Refactor for C'.

Both have some impressing features, but both as well are far from perfect. Extracting a large block of code usually is not done satisfying without manual modifications - and therefore does not pay off. 'Visual Assist X' has nice features such as much more complete autocompletition etc. But it leads to so much flickering and slows down much at certain points. By my opinion therefore the answer is: 'No, there is no production ready refactoring tool for C' UPDATE March 2015 As for hdoghmens reply today i tried Resharper for C.

His link does not say anything about C. But i found Resharper C that was announced more than a year ago here: I gave it a try with VC2010 using a code base of 20MB.

Test 1: Extract Method: results in a Resharper exception. No source code changed.

Test 2: Extract Method with different source: Works fine Test 3: Change signature of extracted function: Results in broken C code: bool myclass::dowork123(int& Filled.&, long, int&) Maybe thats why C its not listed on the main page. By my opinion the answer to this question still is 'NO'. Our is a transformation engine designed to carry out complex transforms over large bodies of code, including C. It has been used to make reliable changes on systems of millions of lines of code. It operates by using compiler-accurate langauges analyzers and transformers.

It has a full C parser with name and type resolution, builds ASTs of code, can apply procedural or source-to-source transformations (with C surface syntax) to revise those trees, and regenerate compilable output with comments preserved. (Edit: 7/1/2011: Now does C1X to the extent we understand the standard:) It has been used on large scale reengineering projects, including C component re-architecting, and 100% fully automated translations between langauges. You can read about this at the website.

DMS is also used to build arbitrary source analysis tools. Examples include clone detection, test coverage, smart difference (comparision of source code structures and abstract editing operations rather than lines with simple insert and delete), etc. What it is not (presently) is an interactive refactoring tool. We believe that to do most refactorings well, you need deep control and data fow analyses.

DMS has generic machinery to support this, and that machinery is implemented for C, COBOL and Java at this point, with C being next in line. This is a tough job. You won't see a lot of serious C refactoring tools from anybody until this kind of problem has been solved well. First you need a full C parser:- EDIT 7/5/2011: Looks like we are going to take a run at the interactive version. We have won a Department of Energy Phase I SBIR to investigate how to do this. See (Look for Semantic Designs under 'Texas').

Don't expect a result in a hurry; this is just the start of 3 phase multi-year program to get to a tool. EDIT 8/11/2011: First progress. We now handle all of C0x and OpenMP directives. EDIT 1/4/2012: Does full control flow analysis of C code. EDIT 9/15/2014: Now have C14 front end parser/transformation engine well in hand.

Even does rename pretty reliably at this point:-. Dunno what you mean by 'elegant output'.

The output you get from DMS clearly depends on what you give it, and what transformations you apply. If the transformation don't touch part of the code, that part of the code is as elegant or not as it was in the first place. If it does touch the code, the elegance is determined by how clever the transformations are, just as a coder's manual changes would be.

I don't think of this is elegance, but the formatting of the result can either be 'fidelity' printing (the original format), or a defined prettyprinting style. – Jul 7 '11 at 16:56. I recommend to try if you use emacs and haven't tried it yet (there is also a for vim available). It is a clang based client/server application that indexes C/C code, with these features included:. go to definition/declaration.

find all references, go to next/previous. rename symbol.

integration with clang’s “fixits” I decided to give it a try after watching this which introduced rtags (and emacs) for me. (I have to say that I went this far only after my QtCreator failed to rename some symbols properly, which is a show-stopper for my using this great IDE for now) Besides what is supported by rtags, I also need some additional neat features, including:. create function definition/prototype.

extract function. create getter/setter methods For these, I recommend to use a package for emacs (not sure if there are alternatives for vim) Generally, clang based tools looks very promising. If you are interested in more information about clang tools for C refactoring, including for projects with large codebase, there are talks by Chandler Carruth. I recommend you try. It allows you to analyze large C/C codebases to discover the archtecture, identify problematic dependencies, and re-engineer the code to improve modularity and reduce technical debt. Lattix also provides a number of algorithms to help in the refactoring process. These algorithms help you figure out how to move elements from one part of the hierarchy to another, to break cycles and to move subsystems so that the coupling and cohesion of subsystems can be improved.

Here are the results of Lattix analyzing the (1.6 million LOC of C/C). Full disclosure: I work for Lattix.

Refactoring In C#

The First Hands-On, Practical, All-Ruby Refactoring Workbook! Refactoringthe art of improving the design of existing codehas taken the world by storm. Now, for the first time, there's a refactoring workbook designed from the ground up for the dynamic Ruby language. Refactoring in Ruby gives you all the realistic, hands-on practice you need to refactor Ruby code quickly and effectively. You'll discover how to recognize 'code smells,' which signal opportunities for improvement, and then perfect your program's design one small, safe step at a time.

The book shows you when and how to refactor with both legacy code and during new test-driven development, and walks you through real-world refactoring in detail. The workbook concludes with several applications designed to help practice refactoring in realistic domains, plus a handy code review checklist you'll refer to again and again. Along the way, you'll learn powerful lessons about designing higher quality Ruby softwarelessons that will enable you to experience the joy of writing consistently great code. In this one-of-a-kind book, Microsoft MVP Danijel Arsenovski shows you how to utilize the power of refactoring to improve the design of your existing code and become more efficient and productive. You?ll discover how to perform unit testing, refactoring to patterns, and refactoring to upgrade legacy Visual Basic code. As you progress through the chapters, you?ll build a prototype application from scratch as Arsenovski walks you step-by-step through each process while offering expert coding tips.

Ruby is an agile object-oriented language, borrowing some of the best features from LISP, Smalltalk, Perl, CLU, and other languages. Its popularity has grown tremendously in the five years since the first edition of this book. The Ruby Way takes a 'how-to' approach to Ruby programming with the bulk of the material consisting of more than 400 examples arranged by topic.

Each example answers the question 'How do I do this in Ruby?' Working along with the author, you are presented with the task description and a discussion of the technical constraints. This is followed by a step-by-step presentation of one good solution. Along the way, the author provide.

Praise for Design Patterns in Ruby ' Design Patterns in Ruby documents smart ways to resolve many problems that Ruby developers commonly encounter. Russ Olsen has done a great job of selecting classic patterns and augmenting these with newer patterns that have special relevance for Ruby. He clearly explains each idea, making a wealth of experience available to Ruby developers for their own daily work.'

-Steve Metsker, Managing Consultant with Dominion Digital, Inc. 'This book provides a great demonstration of the key 'Gang of Four' design patterns without resorting to overly technical explanations. Written in a precise, yet almost informal style, this book covers enough ground that even those without prior exposure to design patter.
