* lisp/ob-comint.el (org-babel-comint-in-buffer): don’t add to comint-input-ring
Previously, babel code would be added to the comint input ring of a babel session, making interactive use of the session difficult: one had to page through the babel generated commands when browsing the comint history with M-p/M-n. The session repl’s history should just contain commands the user has specifically entered in the repl buffer, and not those which are fed in from org mode. So, we bind ‘comint-input-filter’ to a function that always returns nil in the ‘org-babel-comint-in-buffer’ macro, to avoid any additions to the input ring while executing code from babel. --- lisp/ob-comint.el | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/lisp/ob-comint.el b/lisp/ob-comint.el index 4e2b352..1f28a2c 100644 --- a/lisp/ob-comint.el +++ b/lisp/ob-comint.el @@ -53,7 +53,8 @@ executed inside the protection of `save-excursion' and (error "Buffer %s does not exist or has no process" ,buffer)) (save-match-data (with-current-buffer ,buffer - ,@body)))) + (let ((comint-input-filter (lambda (input) nil))) + ,@body))))) (def-edebug-spec org-babel-comint-in-buffer (form body)) (defmacro org-babel-comint-with-output (meta &rest body) -- 1.8.4.1
