OK, it is now merged.

Cool, thanks.

Meanwhile, I found the bug -- I was trying to do too much at once.  But please
do test the solution as well.

I've got r374 and will test it with real world code over the next few days.

 Hi Georg,

I have some more changes that I'd like to discuss before committing.  (These
are features in my patched version at bitbucket.org/birkenfeld/dotemacs).
 
Basically:
 
* a separate face for class names:  font-lock-type-face is meant for types in
  type declarations and therefore usually not a very noticeable face.  For
  example I like to have class names underlined, but having
  font-lock-type-face underlined looks very odd in c-mode.
 
* a separate face for exception classes: somewhat redundant, but looks nice.
  Both for builtin exceptions and any name after a raise or except.
 
 Both of these sound good to me.  I checked out and tested your branch, and
 reviewed it.  I think there are only two minor issues that need fixing, but it
 otherwise looks good.

Okay, I'll have a look at the customization issue.

* special locking for escape sequences and %-formatting codes in strings, like
  the equivalent feature in elisp-mode.
 
  (The code seems to have some issues with font-locking buffers, so I'd be
  glad for suggestions how to fix it.)
 
 I'm not sure I understand what the issues are.  I tested it with a few Mailman
 files and it looked okay, though the extra bolding was a little off-putting
 (yeah, I'll be customizing those faces as soon as your changes land :).
 
 What are the problems?  Not that I'm an expert on all the insane font-lock
 possibilities.

The problem is that after applying this patch, I see larger files
mis-highlighted when I open them and jump to somewhere in the middle of the
buffer (or when the point is placed there automatically on openening, because
that was my last editing position).

Basically, I guess some string boundary isn't recognized, and the highlighting
string - code is reversed: code is highlighted as string, and vice versa.
It can be fixed by moving point into a correctly highlighted region and
calling `font-lock-fontify-buffer'.

* no filling in code (that one is pretty simple, just remove the fill-
  paragraph in the last condition of py-fill-paragraph).
 
 +1!  If that's the bug I think it is, it's been annoying me for about a
 bazillion years.  E.g. I want to be able to fill comments for sure, maybe
 strings, but never code.

Yep, that's that.

BTW, while looking at this, something is still not quite right with the
parsing of triple-quoted string literals... as can be witnessed when filling
a TQS with embedded SQS...
 
 Can you provide an example?

Try filling this string:


The output conforms to the XHTML version 1.0 Transitional DTD
(*almost* strict).  The output contains a minimum of formatting
information.  The cascading style sheet html4css1.css is required
for proper viewing with a modern graphical browser.


It results in this:


The output conforms to the XHTML version 1.0 Transitional DTD (*almost* strict).
The outputcontains a minimum of formatting
information.  The cascading style sheet html4css1.css is required

behaving as if the string stopped at the single double-quote before contains.

The font-locking *seems* to be all-right, however I've still seen an instance
where the text between the single quotes has code-coloring -- cannot reproduce
though.

If I can figure out how to do it, I'll commit these changes separately to a
private branch on launchpad, so that they can be reviewed.
 
 Two additional things would be nice if anyone's so inclined.
 
 * Adding a NEWS file; I don't care how far back into history it goes.
 * Maybe some nice screen grabs of face examples so folks have a visual way of
   seeing what their font-lock options are.

I'll see what I can do.

cheers,
Georg

But with no change to the buffer other than that?  Sounds like possibly a bug
in Emacs, though I also vaguely recall that font-lock did or does have some
maximum limit of buffer size on which it operated.  I think this was put in at
the time where then-modern machines really couldn't keep up with on-the-fly
highlighting.

Confirmed, and if you change those embedded double quotes to single quotes,
the paragraph fills correctly.

where the text between the single quotes has code-coloring -- cannot reproduce
though.

Me neither with r372.

If I can figure out how to do it, I'll commit these changes separately to a

Thanks very much for adding the NEWS file!

Thanks Andreas and Georg for your recent commits to python-mode.el.  I wonder
if it isn't time to start thinking about an official release, probably of 5.2?
Is there anything else anybody would like to get in, say over the next couple
of days?  If not, I'd be happy to do a release on Friday, but wouldn't mind if
someone else wanted to do it instead.

Hi Barry,

I'm glad seeing python-mode proceeding.

As for a release, AFAIU we don't have reached Milestone 5.1.1 yet.

Bug #473525 isn't dealt with.
Wanted to look at next days.

Too for my taste there are much more bugs we could adress an current 
code base still.


I'm pretty sure more triple-quote-string bugs exists.
Hopefully I'll be at it next month.

Cheers

Andreas

Embed a single-quoted string in a triple-quoted one:

This is a single-quoted string inside a triple-quoted one.

It does not color properly; the contents inside the single-quoted string 
are not colored as if it were part of the string.
