Re: [Orgmode] [babel] org-babel: tangling to latex .sty/.cls files

[Dan Davison]

Unless I hear views to the contrary from other org-babel users, I'm
going to change this later today so that, when a file name is supplied
for tangling, org-babel no longer attempts to guess the file
extension. The only situation when tangling will guess the file name
extension is if you supply ':tangle yes' in which case the behaviour
will be as it is currently (i.e. the org file name, minus .org, plus the
extension defined in org-babel-tangle-langs.)

The patch I propose to apply is below.

For a file named z.org, here are what some blocks will tangle to with
this patch.

#+begin_src sh :tangle yes                => z.sh
#+begin_src latex :tangle latex-code      => latex-code
#+begin_src latex :tangle latex-code.tex  => latex-code.tex
#+begin_src latex :tangle a.cls           => a.cls
