Subject: [PATCH] Common Lisp source blocks are now wrapped in a LET form which binds the symbol *default-pathname-defaults* to the directory in which the org file resides.

Message-ID: <BANLkTikRAF-D-QQqjEnNEsEcGApexxGZjQ@mail.gmail.com> (raw)
This may be contentious and break backward compatibility for some people.
Currently, relative pathnames in Common Lisp source blocks are
meaningless as the *default-pathname-defaults* symbol is set to
whatever the value is when SLIME was invoked. This behaviour is
contrary to the shell source block processor (I haven't checked the
This is in /tmp/example1/test.org
This is in /tmp/example2/test.org
The attached patch brings this expected behaviour (well from my point
of view) to lisp source blocks. Given the behaviour of Emacs commands
like DIRED and COMPILE, I think the patch makes things more
I couldn't figure out how the sh block processor determines the path
to the org file so I hacked together something that works using some
of the Org hooks.
lisp/ob-lisp.el: Added new variable ORG-BABEL-LISP-CURRENT-BUFFER
which is used to store a reference to the currently being processed org file.
This variable is setq'd in the hooks for
ORG-BABEL-PRE-TANGLE-HOOK, ORG-CTRL-C-CTRL-C-HOOK and
lisp/ob-lisp.el (org-babel-expand-body:lisp): The code sent to SLIME
is now wrapped in a LET block which binds
COMMON-LISP:*DEFAULT-PATHNAME-DEFAULTS* to the directory where the
currently being processed org file resides.
