Hi,

I'd like to build support of Python mode into my Typesetter minor
mode [1].  In particular, I don't want it to insert special characters
outside of Python strings (and maybe comments.)  How do I determine if
the point is inside a string in Python mode?  Is there a better way
than checking 'face property?

How do you do it in other major modes?  I don't think python-mode is special
in this respect.

How 'bout (nth 3 (syntax-ppss <pos>)) ?

Well, I heavily depend on major mode.  Typesetter mode converts normal
characters like " and - to typographically valid punctuation characters,
like “”, ‘’ or — etc.  Of course, such characters must not be inserted
in contexts that don't expect them, e.g. outside strings in programming
modes.

Thanks.  Documentation says it parses Lisp syntax, however.  Will it
give proper results in Python buffers?

BTW, there is `syntax-ppss-context', which seems to be more high-level.
However, it is not documented.  Can I still use it or should it be
considered private?

That doesn't tell me "how you do it" in other major modes.
E.g. how do you do it in C mode?

Report it as a documentation bug.

It's used by font-lock.  Try it,

I don't recommend its use,

I use `c-in-literal' and `c-literal-limits'.  If `syntax-ppss'
works with all modes (i.e. more generic), I should use that one
instead, of course.

Uh, can it be just fixed, without additional bureacracy?  AFAIK
there isn't even a bug tracker for Emacs, though I may be wrong
here.

OK, I already did.

syntax-ppss should work with more or less all modes, but it may not be
100% in all modes, depending on how faithfully syntax-tables can express the
language's lexical rules.

Yes, except I'm not sure how to fix it, so it's better to bring it to the
attention of other people.

M-x report-emacs-bug will send an email to the proper place.  Much quicker
to use than a bug-tracker.

Except modes like nxml-mode which does their own parsing IIUC.
