nXhtml-mode font-lock customizations ??

[William Case]

Hi;

I have been happily using nXhtml for over a week now.

I would like to take a look at the font-lock-faces for different modes
(HTML, PHP) and perhaps make minor adjustments.  Do I customize the
font-lock-faces for each mode separately, change the syntax table or is
there a combined nXhtml font-lock-faces customization?

For example on my current file a long red line/underline (mainly in some
empty lines, but in some text) shows and a can't figure out what it
represents, if any thing.  A red underline shows up under some tags.  If
it is showing an error, those lines are not errors (I believe -- the
page works?).

Those lines are flagging errors in your code. The page may display
correctly because most browsers tend to be very forgiving. You might
check to ensure all of your tags have corresponding closing tags (even
the <p> tag) as a starting point.

You would have to do it for each mode (html-mode, php-mode etc). Please 
notice however that for nxhtml-mode the fontification for html-mode is used.

See the documentation, ehum, the "News and Notes about nXhtml" for info 
about the red underlines.

Error:  Some tags are capitalized and this shows up underlined in red as
an error, as it should.  Lower casing those tags removes the red
underline.

Still don't understand why <? ... ?> deserves a full line error.  For
example,
"    <!-- ==============  STANDARD FOOTER  =============== -->
<?php
   include "includes/footer-oclug.html";
?> " is marked as an error.  If there is, in fact, a php error here I'll
double check the manual, but I don't see it and it works.  Works right
in php-mode.   Getting warning in other buffer "Error
(mumamo-fontify-region): Should not happen"

Just wondering if nXhtml is correctly identifying an error. 

And, I would like to brighten (change the blue shade ) of the <TAGS> and
if possible make some small changes so that php tags etc. more closely
resemble the font-lock-faces I have set up for php-mode.

Lennart, excuse my most recent post.  I jumped the gun.  Stuff is coming
clearer as I delve deeper.

This is a good question and I need to explain. The validation (that 
gives the red underlines) is done by the validation code from nXml. That 
code is very good for XML, but knows nothing about PHP. In nXhtml I try 
to use the same validation code for PHP too. It therefore gives some 
nonsense error.

In the future the validation code ought to be taken out and changed so 
that it can handle PHP (and similar cases) better. However that is a big 
and difficult job and nothing I can do now.

I still think however that the validation code is very useful because it 
is this code that also gives the context sensitive completion in the 
XHTML part of PHP code.

The red underlines are sometimes useful, sometimes not. You can turn 
them of with C-c C-w.

That is a bug. I hope I have fixed this. If you want to test then please 
use the beta code here:

   http://ourcomments.org/Emacs/DL/elisp/nxhtml/beta/

> And, I would like to brighten (change the blue shade )

That is a defcustom in the group 'mumamo (or 'nxhtml).
