What is a good tool to aid in browsing/following C code? [closed]

Answer 1

I've heard amazing things about OpenGrok. I know another team at my place of employ uses it and they find it very handly. From its web site:

OpenGrok is a fast and usable source code search and cross reference engine. It helps you search, cross-reference and navigate your source tree. It can understand various program file formats and version control histories like Mercurial, Git, SCCS, RCS, CVS, Subversion, Teamware, ClearCase, Perforce and Bazaar. In other words it lets you grok (profoundly understand) the open source, hence the name OpenGrok. It is written in Java.

Answer 2

I support the use of doxygen.

This tool generated a javadoc like bunch of html pages, allowing to index all the code, to browse in it (where is this function used, and by which function...), like you can do in an IDE. It is very easy to make it work.

I had once to maintain 2000 files of C code of a 15 years old C project. It took me an hour to index the code with doxygen a provide the other developers with the generated doc. (I know, this phrase sounds like an add, but it is true... It's really a nice tool)

A wonderful tool, which works on all C-like languages.

Answer 3

I use kscope, which uses cscope in the background, but provides function lists etc. as well. Seems to handle large projects like the linux kernel well too. The kscope homepage has a good concise description of what it does and doesn't do.

Answer 4

You can't get anything better than SourceInsight.

Answer 5

Vim and Ctags works for me.

Answer 6

Go for Doxygen and set EXTRACT_ALL to YES. It is simply powerful and easy. Once you love it, you can stick to it across all platforms and languages.
