Hello,
maybe you can start with a simple:
#+NAME: hash-from-lisp
#+BEGIN_SRC emacs-lisp
(shell-command-to-string "git rev-parse HEAD" )
#+END_SRC
#+RESULTS: hash-from-lisp
: 099b6ceee7264832b8e13f1156974b8017e6e4bb
You can hide the result using proper headers or the noexport tag and
then print the result in a verbose way:
The latest commit hash is src_emacs-lisp[:var i=hash-from-lisp]{(format "%s" i)}
or if you enable the shell in babel you can start with:
#+NAME: hash-from-shell
#+BEGIN_SRC shell
git rev-parse HEAD
#+END_SRC
For latex only, I use the following snippets. This works with gitinfo2
(in debian you need the packages texlive-latex-extra and
texlive-latex-extra-doc). Sorry for the long lines...
Please note that this will also highlight the dirty status of the repo,
since adding the latest hash for a modified version make little sense.
Best,
Daniele
