Avoid ever using popen on Windows, since it's broken there. Factor out the business of getting the summary line into splitdoc(). Use the modulename() routine in inspect. Show all members of modules and classes rather than filtering on leading '_'. Small typo and formtating fixes. Don't show warnings when running "pydoc -k".

"""Generate Python documentation in HTML or text for interactive use.
|
|
|
|
In the Python interpreter, do "from pydoc import help" to provide online
|
|
help. Calling help(thing) on a Python object documents the object.
|
|
|
|
Or, at the shell command line outside of Python:
|
|
|
|
Run "pydoc <name>" to show documentation on something. <name> may be
|
|
the name of a function, module, package, or a dotted reference to a
|
|
class or function within a module or module in a package. If the
|
|
argument contains a path segment delimiter (e.g. slash on Unix,
|
|
backslash on Windows) it is treated as the path to a Python source file.
|
|
|
|
Run "pydoc -k <keyword>" to search for a keyword in the synopsis lines
|
|
of all available modules.
|
|
|
|
Run "pydoc -p <port>" to start an HTTP server on a given port on the
|
|
local machine to generate documentation web pages.
|
|
|
|
For platforms without a command line, "pydoc -g" starts the HTTP server
|
|
and also pops up a little window for controlling it.
|
|
|
|
Run "pydoc -w <name>" to write out the HTML documentation for a module
|
|
to a file named "<name>.html".
