From f6fd65f8e80b6efa0a5db084a9c9f94d46e67515 Mon Sep 17 00:00:00 2001 Message-ID: From: Ihor Radchenko Date: Tue, 9 Jan 2024 19:08:44 +0100 Subject: [PATCH] ob-R, ob-julia: Do not force-start session in Org Src buffers * lisp/ob-R.el (org-babel-R-associate-session): Set `ess-gen-proc-buffer-name-function' to associate the right session buffer if user requests session interaction from inside Org Src edit buffer. (org-babel-edit-prep:R): Remove in favor of `org-babel-R-associate-session'. * lisp/ob-julia.el (org-babel-julia-associate-session): Implement analogous functionality. (org-babel-edit-prep:julia): Remove in favor of `org-babel-julia-associate-session'. * etc/ORG-NEWS (~org-edit-special~ no longer force-starts session in R and Julia source blocks): Document the change.
