List all available classes and functions

How can I get a list of all available classes and the corresponding methods in Sage?

The reason I ask is that I would like to create a syntax file for the editor Kate. I have not found one so far, if there is one, this would also solve my issue.

Sage is written mostly in python, so I suspect if you can answer this question for an arbitrary python library, you can answer it for Sage. I mention this because there may be help elsewhere for the more general case.

The answer may depend on what you mean by "available". I think this gives a list of all classes in Sage's default namespace:

import inspect
[_ for _ in dir() if inspect.isclass(eval(_))]

To get a more complete list, I suppose you could replace dir() with dir(MODULE) and then iterate over all py and pyx files in Sage's library (as in dir(sage.algebras.steenrod.steenrod_algebra_misc)). To do this iteration, you might use os.path.walk. Once you've found a class, dir(CLASS) should give you its attributes and methods.

Each directory and subdirectory in the sage source has a file named which lists all the class names that should be imported when one does from this.package import *. The top level one is here. This is a lot of stuff, but maybe not quite _every single_ class. Is that enough for what you want though?

Note: Getting all the classes seems like a good start, but I don't know how to get all the method names of a class -- python's dir does this for an _instance_ of a class, but that's not the same thing.

Maybe the reference index can help:

It is a bit messy to parse; it feels like it should be possible to do from within Sage. In Mathematica, it is quite easy to do this.

how is that list generated? presumably something that sphinx does . . .
