I cannot seem to be able to make org-babel-tangle respect the setting of
org-babel-tangle-use-relative-file-links to t. Here is my process after
launching "emacs -Q" (the default for
org-babel-tangle-use-relative-file-links appears to be true in this
configuration):
1. Write example org file named test.org with the following basic
contents, making sure that the top line is refreshed with C-c C-c:
#+PROPERTY: header-args :tangle test.py :comments link
* My top level
Here is my description
#+BEGIN_SRC python
print("This is my code")
#+END_SRC
2. Run M-x org-babel-tangle on the org file, which produces test.py with
the following contents:
# [[file:d:/mytest/test.org::*My%20top%20level][My top level:1]]
print("This is my code")
# My top level:1 ends here
As can be seen in the first line, it uses an absolute file path
containing my org file and py file, rather than the expected relative one.
I looked through the ob-tangle.el file to try and see why this is the
case, and it looks like there's some negative boolean result in this if
statement in the org-babel-tangle-single-block function which causes it
to skip over the code that would make use of the relative path:
(if (and org-babel-tangle-use-relative-file-links
(string-match org-link-types-re link)
(string= (match-string 0 link) "file"))
(on the online copy of the code, this is the region under consideration:
https://code.orgmode.org/bzg/org-mode/src/master/lisp/ob-tangle.el#L475
I have not yet tried the most recent development copy because I do not
see considerable difference in the relevant lines compared to the
version of ob-tangle.el I have, but I can try the development copy as a
next step)
Here is the additional bug reporter output, on my Windows 10 64 bit
computer.
