Subject: Make ob-shell conform to the org-babel interface
Date: Wed, 27 May 2015 17:30:27 +0200 [thread overview]
Message-ID: <3651FC40-E9B3-4027-91D7-DD03147591C4@infomedia.uib.no> (raw)

Hi,
I found that ob-shell’s org-babel-variable-assignments:bash function does not respect the interface for org-babel. It takes multiple arguments when it should only take 1. This is a problem when f.ex. org-babel-sha1-hash tries to expand the body of a bash source block and tries to call that function with only 1 argument.
I am not sure if the following patch follows best practices in the project, but it solves the problem for me.

Subject: [PATCH] ob-shell: Conform to variable assignment interface
Change org-babel-variable-assignments functions in ob-shell to use the
same function so conform to the interface used for variable assignment
in org-babel.
