Hi Eric,

playing with your file I found out = that setting :noweb to yes does the trick. It doesn't work here without = setting it. It was set to tangle in the file I tested this with, which = seemed the problem. Thank you for helping me with this. I still got = problems with :vars on exporting, but I'll answer to the other mail for = this to not mix the threads up.

As for the detangeling part: Its = theoretically impossible to do that without comments. There is no = reliable way to tell which block is which (after it was edited) without = some sort of reference in the file. Some sort of probabilistic method = could yield somewhat useable results but I'd go for determinism (with = comments) here.

Hi = Dirk,

Using the = simple attached Org-mode file,

#+source: def-something

#+begin_src sh

= SOMETHING=3Dnothing

#+end_src

#+begin_src = sh

= <<def-something>>

= echo $SOMETHING

#+end_src

When I call C-c = C-v ' in the second code block I get a buffer = containing

--8<---------------cut = here---------------start------------->8---

<<def-something>>

echo $SOMETHING

--8<---------------cut = here---------------end--------------->8---

but when I call = C-c C-v v in the second code block I get a = buffer

containing

--8<---------------cut = here---------------start------------->8---

SOMETHING=3Dnothing

echo $SOMETHING

--8<---------------cut = here---------------end--------------->8---

with the noweb = reference expanded. I would suggest making sure you = are

on the latest version of = Org-mode, and if you still don't get this

behavior then I would recommend starting emacs with the -Q = option to see

if part of your = config is changing this behavior.

I agree with = your points below, I think the main complication = is

introduced when the = restriction to work w/o comments is added (to = allow

working with non-lp/org = users). The main limiting factor right now = is

simply developer time to = implement and test the debugging behavior

you've described below. You may want to try the = existing

org-babel-detangle = function, as (if you don't have nested blocks) = it

should be sufficient to be = useful in your current situation.

Best -- = Eric
