Useful syntax highlighting (font lock) in a mixed xml lua file

Useful syntax highlighting (font lock) in a mixed xml lua file

[Timur Aydin]

Hi,

I am working on an xml file that has an embedded CDATA section which 
contains lua source code. I am mostly working on the lua code and would 
like that code to be syntax highlighted by emacs. When I activate 
lua-mode, it understandably gets confused because of all the surrounding 
xml. When I activate xml-mode, the xml stuff is properly syntax 
highlighted, but the lua code in the CDATA section is uniformly colored 
plain text.

Is there a way to utilize font-lock mode in a sensible manner? I 
attempted to put the lua code in a separate file (script.lua) and then 
included it into the xml using DOCTYPE and ENTITY tags, but this didn't 
help, because I don't have any control over the software that parses 
this xml file. It isn't able to deal with extra xml tags.

So my only hope is to be able to tell emacs to font-lock a region 
bounded by a CDATA tag using lua-mode and to font-lock the rest using 
xml-mode. Is there a way to do this?

Hello and a happy new year to everyone!

I had sent the following post to the help-gnu-emacs group, but thinking
that it might require some special lisp programming, wanted to post the
same question here as well...

In principle this can be done by defining a multi major mode with
mumamo (which is part of nXhtml).

There are several examples in nXhtml for how to define multi major
modes. (See all the .el files that have "mumamo" in their names.)

I don't know how to do that.

Did you consider using an indirect buffer? If you have the indirect
buffer narrowed to the Lua code and with the correct major-mode,
font-lock should work there.

Perhaps you can use MuMaMo?

   http://www.emacswiki.org/emacs/MuMaMo

   "Mumamo is a library for cooperation of multiple
   major modes in a buffer. mumamo divides the buffer
   into chunks, each with its own major mode."
