Visualising Code Structure in Large Projects?

Posted by Cliff on from the 100k-LOC dept.

TheMaccLads asks: "I've recently joined a new C++ project, and it's in a terrible state. There are 100-odd source directories, dozens of libraries, and a couple of dozen executables and DLLs. Some executables pull in (i.e. compile themselves) the occasional source file from a library, instead of using the libraries. My job is to port a subset to unix, but I need a tool to visualise all the relationships between directories, projects, libraries, and so on, because my brain will overheat soon otherwise. Preferably a tool that will do it by parsing the MS Dev studio projects and workspaces, but if I have to write it myself in Perl, I will! Anyone know of any tools? Or suggest an approach?"

  1. Post-It notes and a DryErase Board, Bake at 350 by QuietRiot · · Score: 3, Funny

    5 People
    3 Afternoons
    1 Huge Pile of Code
    2 Large White-boards
    3 small little cubes of those MultiColored post-ITs
    2 Handfuls of assorted colors DryErase markers

    Start by pouring all the ingredents into a medium sized classroom-type-room with lots of chairs and a small assortment of refreshments. (Be sure to wash off the white board.) Tell all the people what you are trying to do and tell them they will have to help you out for at least one afternoon over the next couple of days. [Whatever. Intimate time with code. They'll learn something. You'll get to talk to eachother.] Tell some they have to stay, others they'll have to help you tomorrow, etc. Look over the code and decide which portion you'd like to work with today. Isn't it pretty? Now - by applying the markers and the PostITs to the White-board, carefully extract the useful parts of the code, leaving the nasty, hairy choke behind. Go for the structure. Go for the connections. Dispose what is leftover. Take a high resolution picture. Go home and get some sleep.

    Repeat the above for each piece of the program you'd like to work on for each particular day. After you have extracted all the good, and none of the bad, combine the extract with your wonderful programming skills, the sarcastic cheers from your friends in nearby cubicles, and big high-resolution printouts of your photography work in a CPU Unit Processor, blending until firm. Chill, Serve and Enjoy!
