Searching for the Perfect Inline Code Documentation Tool

Even amongst programmers I’m weird because I have an intense love for documentation. No, that doesn’t mean I overly comment my code, or that you’ll catch me browsing happily through the product requirements document during my coffee break. I should be more specific.

I have an intense love automatic documentation generation. Nothing makes me more tickled pink than seeing code and documentation living side by side in perfect harmony. I hate seeing documentation put on the company intranet only to diverge from the code it’s supposed to explain as the days go past. I hate hitting my head against a brick wall as I’m pouring through the source code trying to understand an API because at no point does it mention that it’s documented in a Word doc in another directory.

This is my rule of programming: documentation should live beside the code it documents, in the comments, especially if it’s API documentation. If your language of choice doesn’t already have some kind of automatic code generation tool then you’re probably using the wrong language.
