No, this looks like a bug in comint.el. ob-shell correctly sets PROMPT to be org-babel-sh-prompt, which is "org_babel_sh_prompt> ", with space! The fact that the comint output does not, in fact, contain space is wrong. We can probably remove the space in org-babel-sh-prompt to work around this (likely, Emacs) bug. > It could be that `test-ob-shell/session-async-evaluation' doesn't test > correctly, but it looks right to me (I could certainly be mistaken). > Therefore, I see only two options to fix it: remove a space from the concat > expression (which I did in my latest patch) or remove a space from > `org-babel-sh-prompt'. Removing space from the concat expression in plain wrong, as Max explained. -- Ihor Radchenko // yantar92, Org mode contributor, Learn more about Org mode at <https://orgmode.org/>.
