org-mode, vc, and read-only files:

[T. V. Raman]

Would it be possible to make org-cycle work on read-only files
--- suspect we just neeed to wrap its body in a 
(let ((inhibit-read-only t))...)

At present, if you put your org files under vc control, with RCS then
opening a checked-in  file i.e. one that is read-only, causes an
error since org-cycle is unable to change properties on read-only
content.

Hi Raman,

I sure could wrap the relevant parts in org-cycle with 
inhibit-read-only, but so far I cannot reproduce the error.  When I am 
loading a write-protected file,  I am getting a "Note: file is write 
protected."  This note is delivered as a message only, and after that 
everything proceeds normally.  In the buffer I seem to be able to use 
org-cycle freely even though it is write protected.  I think this is 
because outline-mode uses overlays, not text properties.  So I am 
guessing that it is not org-cycle which causes the error.

Can you give me more hints as to what the problem really is?  Maybe an 
example file that hits the error and produces a backtrace?

Thanks.

- Carsten

Actually your message told me enough to debug the problem, the
culrpit was I (or rather emacspeak) which  implements voice lock
purely via properties, and in that process maps overlays to
properties for its own purposes. So the fix should go into
emacspeak -- I'll check it in at this end.
