How to find current font-lock settings of a buffer?

How to find current font-lock settings of a buffer?

[Geralt]

Hi,

how can I see the current font-lock settings of a buffer? I'm asking
because the default theme does a very good job at highlighting in
C++-mode but my custom-theme does not (yet).

M-x describe-face RET on character of that face. In GNU Emacs 23 C-u  
C-x = works similarly.

None.
They just redefine "dark" as the new standard.

Thanks, that helps :-)
Only one problem remains: is there a way to find out if it is using a
certain font (default font for example), because another, more
specialized, font is unset?

Sorry, I've used the wrong word, what I wanted to ask was: if a
certain word ist displayed with the default face is there a way to
find out if the mode really wanted to display it with the default face
or is it just using the default face, because I didn't customize a
more specialized face?

Launch another GNU Emacs with -Q or -q and compare their results!

That displays only the face used for that character.  The real font-lock
settings are in the variable font-lock-keywords (which you normally
don't set explicitly).

See (info "(elisp)Font Lock Mode") for details.

Yes, but looking at the value of `font-lock-keywords' is likely to puzzle more
than clarify ... unless you marry that with the face appearances using
`list-faces-display'.

IOW, `C-h v font-lock-keywords' will show you which faces are used by Font Lock
mode in the current buffer. Then `M-x list-faces-display' will show you what
they (and other faces actually look like).

Thanks, I'll try that.
