Hi Rainer,

Hi Eric
=A0

There is one more requirement for tangling with comments, that is the
presence of a :comments header argument. =A0If this argument is not set
for a code block then that code block *will not* be tangled with
comments regardless of the value of `org-babel-tangle-w-comments'.
<= /blockquote>

That explains.
=A0

You can set this variable to default to true for R code blocks with the
following

=A0(add-to-list 'org-babel-default-header-args:R '(:comments . &qu= ot;yes"))

OK - it is working.
What I actua= lly did, was to add
=A0
=A0=A0 #+BABEL: :comments yes

to the h= eaders of the file, so I can control it on a file basis.


Hope this helps.

Definitely.
=A0

I think that moving forward it might make sense to remove the
org-babel-tangle-w-comments variable, as it's confusing to have two
points of control for comments during tangling. =A0Also, it looks like I need to add the :comments header argument to the babel documentation.

Both points agreed.

In addition: is it possible = to customize the format for all comments (on a per file basis and / or a pe= r block basis)? i.e. I don't need the file name, as all blocks are comi= ng from one file. I know about

=A0 #+srcname: <name>

but is there a variable for the line= number (I guess that is covered by the request posted in another thread) o= ne could use?

Also, would it be possible to include a link in the co= mment block, so that clicking on that link actually opens the org-file file= at the location of the source block? That would make editing the code real= ly easy.

Thanks for helping to sort some of these issues out!
