Hi List,
this does not work, although I would think it should (at least if there
is no typo or so):
,----
| #+name: project-root
| #+header: :var buf-file=(buffer-file-name)
| #+begin_src emacs-lisp
| (file-name-directory
| (directory-file-name
| (file-name-directory buf-file)))
| #+end_src
`----
#+results: project-root
: /home/tj/News/drafts/
,----
| #+name: project-name
| #+header: :exports none
| #+header: :var root-dir=project-root(buf-file=(buffer-file-name))
| #+begin_src emacs-lisp
| (mapconcat
| 'capitalize
| (split-string
| (file-name-nondirectory root-dir)
| "-" 'OMIT-NULLS)
| " ")
| #+end_src
`----
#+results: project-name
Wrong usage of :var or limitations of header arguments?

cheers,

I think everything is doing what it is supposed to from an Org-mode
perspective, see below (with different functions).

This is to be expected. The two blocks above compose to something like
#+begin_src emacs-lisp
(file-name-nondirectory
(file-name-directory
(directory-file-name
(file-name-directory
(buffer-file-name)))))
#+end_src
Calling `file-name-nondirectory' on the results of `file-name-directory'
seems like it should give you an empty string.
Best,

Yes, I figured that out myself before I saw your post, there was a
mistake in my code.
Thanks anyway.

This works
,----
| #+name: project-root
| #+header: :var buf-file=(buffer-file-name)
| #+begin_src emacs-lisp
| (file-name-directory
| (directory-file-name
| (file-name-directory buf-file)))
| #+end_src
|
| #+name: project-name
| #+header: :exports none
| #+header: :var root=project-root
| #+begin_src emacs-lisp
| (mapconcat
| 'capitalize
| (split-string
| (file-name-nondirectory
| (directory-file-name root))
| "-" 'OMIT-NULLS)
| " ")
| #+end_src
`----
so it was just wrong usage ... sorry for the noise
