[Orgmode] Use orgstruct-mode to edit TWiki Markup language ?

[Rainer Stengele]

Hi all,

We (have to) use TWiki as a documentation tool in my company.
I already use Emacs erin-mode to edit the TWiki pages which is not bad.

What I am really mssing is something like the outline (folding) 
possibilities of org!

I know org provides the orgstruct-mode, but the problem is the different 
headline format of the TWiki markup language:

Example:

---+ Headline Level 1
   * text
   * text
---+ Headline Level 1
   i. text1
   i. text2
---++ Headline Level 2
---+++ Headline Level 3
---++++ Headline Level 4

I wonder if it would be possible to somehow locally set the regex which 
defines what a headline for org is.
As old perl hacker I would say the regex it is something as simple as 
^---[+]+\s

A configurable headline could serve in all similar cases where you find 
a regular formatted headline.


Of course I would be more than happy to have org produce TWiki markup 
language directly...
