Does anyone know a way to get dedicate line numbers in an org code
block?
I know how to get buffer code lines, but when we run a code block and
there is an error, the error line number is relative to line 1 of the
code block. Currently, we type C-c ' to get a code buffer, and navigate
to the line. I would like to see code block numbers on the right hand
side of the buffer, and only inside the code block. Any ideas?
Thanks,

You mean like
(org-add-hook 'org-src-mode-hook 'linum-mode)
only with line numbers on the right side? (linum puts them on the left)
Or did you mean in the org-mode buffer itself?
Maybe (just a guess) hack `linum-update-window' to reset `line' to 0
whenever `(forward-line))'gives you a line that matches `#+begin_src'.
HTH,
Chuck

No, that is not quite what I need. We already have those line numbers on
the left. I wanted a new set of numbers, only in the src-block, and on
the right so they do not get mixed up with the linum-mode numbers. This
is to avoid having to go into the org-src-mode at all.

I suppose it would involve creating new overlays the way that linum-mode
does.

I came up with a reasonable solution to this that I think is pretty
nice. It doesn't put linenumbers on the src block, but it does something
even better!
The gist is to write the block to a temporary file, then run pyflakes,
pep8 and pylint on it. The output of those goes into a temporary
org-buffer, with links back to the positions in the code block where the
errors are!
The code is laid out here:

I am going to try it out with my students next week!
