One of the common complaints about the Mozilla string code is that it’s very difficult to know what methods are available on a given class. Reading the code is very difficult because it’s hidden behind a complex set of #defines, it’s parameterized for both narrow and wide strings, and because we have a deep and complex string hierarchy. The Mozilla Developer Center has a string guide, but not any useful reference documentation.
With a little hand-holding, static analysis tools can produce very useful reference documentation, which other tools simply cannot make. For example, because a static analysis tool knows the accessibility of methods, you can create a reference document that contains only the public API of a class. I spent parts of yesterday and today tweaking a Dehydra script to produce a string reference. I’m working with Eric Shepherd to figure out the best way to automatically upload the data to the Mozilla Developer Center, but I wanted to post a sample for comment. This is the public API of nsACString:
I am trying to keep the format of this document similar to the format we use for interfaces on MDC. It’s a bit challenging, because C++ classes have overloaded method names and frequently have many methods. In the method summary, I have grouped together all the methods with the same name.
