Re: [O] Let Org-mode babel file result support relative link type by usi

* Does Org-mode `:output-dir` header-argument? Or is `:dir`?

* An example

I can make it (`:results file :file "FILENAME"`) work in `ob-python` like this:

#+BEGIN_SRC python :var fname="QR_I_Love_YOU.png" :dir "data/images" :results file
import qrcode

img = qrcode.make("I Love YOU")
return fname

[[file:/home/stardiviner/Org/Wiki/Computer Technology/Programming/Programming Languages/Python/Data/Packages/data/images/QR_I_Love_YOU.png]]

* More specific suggestion:

Make use of org-mode variable `org-link-file-path-type`.
When user generate a result with link (like: 

[[file:/home/stardiviner/Org/Wiki/Computer Technology/Programming/Programming Languages/Python/Data/Packages/data/images/QR_I_Love_YOU.png]]

Org-mode babel always use relative file path for link, instead of absolute file path like upper example.
For example, if current path is `/home/stardiviner/Org/Wiki/Computer Technology/Programming/Programming Languages/Python/Data/Packages/`, then the relative file path link should be:


* About what one preceduce over the other problem

The header argument `:dir "data/images"` is used to specify my generated image's destination directory.
My suggestion is want a the result link use `org-link-file-path-type`. So the header argument `:dir` is not about the result link. Just it will be used. Like upper example.

It sounds interesting. Could you be more specific about the
specifications of your suggestion.

For example, what happens when :output-dir is set, or when :file already
provides some directory part? What part takes precedence over the other?

Better, could you show some examples, or some tests?
