Subject: Re: Babel eval w/ C-c C-c but not (org-babel-execute-buffer)

Message-ID: <877e5d3zmu.fsf@gmail.com> (raw)

Hello,
I think that even when ":eval no" is set, eval should happen if the user explicitly requests it.
The use case is that I have code that takes an unreasonable amount of compute time to run it in Emacs (e.g. a full day of compute time). I think even with :async this type of code should be run outside of emacs, so I tangle it and run the python or bash scripts in a terminal.
Elsewhere in the project (Org file) I have babel blocks that I want to update throughout the file. I do this by cleaning all result blocks with =C-u C-c C-v k= or (org-babel-remove-result-one-or-many), then executing all blocks (without =:eval no=) using =C-c C-v C-b= or (org-babel-execute-buffer).
In order to not spend days of compute time when I eval (org-babel-execute-buffer), I set :eval no to the computationally heavy babel blocks. But during development it would be nice to run these... hence the conflict with the current Org behavior and my desire for a new feature.
The two-line change at the bottom implements the following behavior:
When the prefix arg is passed to org-babel-execute-src-block, the block is evaluated regardless of the :eval flag.
Note that this doubles up on the prefix arg behavior, which is already set according to the documentation:
> With prefix argument ARG, force re-execution even if an existing
> result cached in the buffer would otherwise have been returned.
Questions for the list:
Is this feature something that makes sense?
If yes, then do you also think that tangling should occur when explicitly requested (i.e. C-u C-c C-v C-t), even if :tangle no is set?
Suggestions for a better implementation?
Thanks,
-k.
