This reverts commit 599a0e9083.
Sorry, we can't simply change the syntax of something as basic as a
link, even if the old syntax is wrong. We need to keep Vimwiki
reasonably backwards compatible.
Two reasons whey the links in markdown wikis are not updated:
1. The markdown link pattern is wrong, should be []() rather than [][];
2. The logic of getting wiki local var cannot get correct wiki index as:
a. the renamed file's buffer is removed and %:p would return empty
b. the function that gets the wiki local var depends on buffer's %:p
value to find the wiki it belongs to and it would always return -1
and result in the default option values instead the user's option
The fix is
1. fix the markdown link pattern regex;
2. keep the renamed file's buffer open during the period of updating the link
Before, the cursor would jump to the TOC a lot when pressing <C-o> etc.,
because it is changed every time the buffer is saved.
Use :keepjumps to make it less intrusive. Sadly, the cursor still jumps
to the TOC when you press u and C-r, but it seems there is no way around
it.
Apparently, switching buffers in connection with disabled events caused
the highlighting to disappear. Solution: use the :wa command to save all
buffers. A disadvantage is that now also non-Vimwiki buffers are saved,
but I think that is bearable.
Will fix normalization of links like [[local:./foo.txt]]
Also, allow schemes to end with a number, so that e.g. [[wiki1:foo]]
will normalize as expected.
The only real condition we care about is whether the selection is
contained within a single line. It is practical to do something like
V<CR> to link a whole line, and AFAIK there is no reason for why that
doesn't work.
