So I'm trying to write a custom function to set regexp search string for c/c++
code by writing org-create-file-search-functions hook. (code #1 below )
After using the hook by issuing org-store-link in c/c++ buffer, and
org-insert-link in org-mode buffer I noticed that the link has slashes instead
of backslashes in my regexp.
So I delved into the org-insert-link code and found out that it calls
expand-file-name on the whole link (filename::regexp) which translates my
regexp's backslashes to slashes. It happens only on emacs on windows,
under linux it is ok.
I also experimented by changing the culprit lines of org-store-link and
it helped (code #2 below) but it seems to be too destructive.
So I'm wondering if it is a bug that may be fixed or my way of doing
it is wrong?
regards,
Rafal
