Hi,
I've defined a derived major mode of `python-mode' using
`define-derived-mode'. However, some of the variables set by
`python-mode' are inappropriate for the derived mode; in particular, I'd
like to disable auto-guessing of the indentation by setting
`python-indent-guess-indent-offset' to nil. However,
`define-derived-mode' has no customization point for running code before
the parent mode function. What's the best way to solve this? Using an
advice? Or not using `define-derived-mode' in the first place?
Thanks,
Philipp

Add the code *after* running python-mode? After all, setting vars
before would be a waste since python-mode (like all other proper major
modes) begins by calling kill-all-local-variables (also known as
fundamental-mode).

Can't see this in python.el. python-mode is a derived-mode from prog-mode.
Customizing python-indent-guess-indent-offset to nil should help already.

Yes, but it would apply to all Python files as well, not only to the
derived mode.

Only the --derived-- python-mode asks for variable
python-indent-guess-indent-offset
and does (python-indent-guess-indent-offset) if t

Yup, it starts by calling prog-mode. Since prog-mode is a proper major
mode it will start by running kill-all-local-variables and hence
python-mode does too. Of course prog-mode itself is a derived mode so
it doesn't directly call kill-all-local-variables, but instead it calls
fundamental-mode, which itself calls kill-all-local-variables (the two
used to be aliases, but nowadays, fundamental-mode does a little bit
more than just running kill-all-local-variables).

You're right, that wouldn't work. The problem is that
python-indent-guess-indent-offset prints a message if it couldn't guess the
indentation; I'd like to suppress that message.

Disabling a message is another thing than disabling auto-guessing.
Look into python.el, definition of
python-indent-guess-indent-offset
Messaging is done from last line there. Put it at an extra line - i.e. a
new line at the end of "(message
" sexp. Than comment out that line.

Sure, but that would disable the message for all users. I could totally
live with that (Emacs is already too chatty), but Stefan would need to
agree that it's fine to remove the message entirely.
