Q: How many lines of C99 code raylib written in?

[ghost]

Nice question liked to ask, Feel free to answer it @raysan5 !

Actually, it's a bit difficult to get a reliable measure. I mean, you can measure the lines of code with, for example, cloc tool, but those measures do not reflect many aspects of the library. Keep in mind that most of the work done in raylib along the year has not been adding many new features but reviewing and improving the internal codebase. Best improvements usually reduced the line count.

As you can see, raylib is a very thin layer over base technologies like OpenGL or system libraries.

Also note that those measures do not include all the examples, templates, build configurations or games created for raylib.

@raysan5 Over 26000 lines of code, That's amazing!
Keep up the great work!

[chriscamacho]

my counter gives an estimated cost if you wanted to pay someone to write Raylib - $798,189 !! add in the externals and it just becomes redonculous !

[raysan5]

@chriscamacho I imagine you used scc to calculate it but I think that tool does not take into account the years of redesigns and reviews with lot of code added and removed. The tool considers lines of code and complexity but raylib has been designed trying to minimize internal code complexity as much as possible, targeting students and novel programmers. Also worth mentioning the work behind the examples, wiki, web, social networks and all the maintenance involved.

I estimate I've invested to date, at least, about 20000 hours in the project (probably more than that).

[chriscamacho]

its not even an estimate really is it? but it can be amusing !
