org-edit-src-code gains extra optional arguments `code' and
`edit-buffer-name'. If `code' is supplied, then this code forms the
contents of the edit buffer, which is made read-only. In this case,
the mechanisms for writing back to the org buffer on save are
disabled.
Optional argument `edit-buffer-name' allows a name for the edit buffer
to be supplied.
This support was totally broken. It works now again. Unfortunately
it is not possible to edit the table directly in the org-mode buffer
anymore - to edit such a table, you have to use C-c '
Saving the edit buffer is achieved by calling org-edit-src-exit,
saving the org buffer and returning to the edit buffer with
org-edit-src-code. When those two functions are used in this context,
they should not attempt to restore the saved window configuration, nor
alter the saved window configuration.
These changes provides frame / window management preferences for the
edit buffer generated using C-c ' on a source code block. Preferences
are specified by a new variable org-src-window-setup, which is based
on org-agenda-window-setup and has the same four options:
current-window, other-window, reorganize-frame, other-frame. These
behave as follows:
* current-window
The edit buffer appears in the current window.
* other-window
`switch-to-buffer-other-window' is used to switch to the edit buffer
in the same frame.
* reorganize-frame [default]
The current frame is reorganized so that it is split between the
source code edit buffer and the parent org buffer.
* other-frame
The edit buffer appears in a new frame. That frame is deleted when
exiting the edit buffer with C-c '.
In org-edit-src-save, point and mark were being restored inside the
save-window-excursion. As it happens, although mark is lost, point
nevertheless retained its position with switch-to-buffer being used to
switch between org and edit buffers, as is currently the
case. However, the failure to restore point correctly is exposed if
more complex options controlling window and frame management are
provided for the edit buffer.
If an active edit buffer exists for a source block, and this variable
is non-nil, then org-edit-src-code will not ask before returning to
the edit buffer, and future saves will overwrite the source block's
contents.
