Hmm, but they're not keywords, at least in the syntax file "with just 
one line"

that you provided.  If they are keywords, ie. you're involving more syntax,
then:  keywords have priority.  Consequently, your region will not start.

Priority:
 * keywords, later ones have higher priority
 * matches and regions, later matches and regions have  priority over 
other matches and regions.


In effect, regions' start and end patterns are special kinds of matches.

So, let me guess: you want a new syntax line such as

  syn keyword xKeyword begin end

because you wish to highlight the words "begin" and "end" differently.  
May I suggest using

the "matchgroup" specification: ie.

  syn clear
  syn region xBlock transparent fold matchgroup=Delimiter start="begin" 
end="end" contains=xBlock

Creating a syntax file with folding

[Marius Roets]

Hi everybody,
I am trying to create a syntax file with folding. However after
pouring over the documentation for hours, I seem to be stuck. I want
to, for instance, fold a begin/end block. I have created a simple
syntax file with just this line:

syntax region xBlock start="begin" end="end" transparent
contains=xBlock,xKeyword fold

As expected, this works well. However 'begin' and 'end' are keywords. So I add:
syntax keyword xKeyword begin
This breaks the fold. It no longer sees the begin. I changed it to
syntax match xKeyword "\"
And now it works again. Now for 'end'. I know that defining it as a
keyword is problematic, so I do a match again.
syntax match xKeyword "\"
This breaks the fold again however. Even though every 'begin' starts a
new fold, 'end' doesn't end them. I tried adding keepend to the
region, but then the first 'end' ends all folds. There must be
something that I am not understanding. Any help would be appreciated.

I have included a file I have used to test.

Thanks
Marius
