de-tangle function?

de-tangle function?

Hi

I remember something about a de-tangle function, which re-imports the
source code blocks into the org file is previously tangled with comments
et al, but I can't find that function any more.

Is it still there? Does it work reliably?

Thanks,

Rainer

You need the code blocks to be wrapped into comments for it to work.

Regarding reliability, it does work well on small examples. I remember having
had really bad results with my huge .emacs file, but hadn't any time to debug
the problem -- try to reproduce -- at that time.

So, when you do it, please keep a backup of your original Org file. It's
safer.

But, if there are bugs, they should be clearly identified, and fixed...

Best regards,

It not always good at finding its way back into the Org file, and I
found that some of the header arguments didn't 'work properlyø for
'complicated' blocks.  I'll see if I can make reproducible examples
later.

It's definitely a potentially cool feature though.  Notice you have to
run it from the tangled file.

Absolutely - especially debugging code (in my case R) would be easier.

Cheers,

Pity - then I can't use it. I have a long org file which tangles in many
.R files and in many cases one file spans across many blocks. I have to
trust it when using it at this stage. But as Eric has improved the
org-babel-tangle-jump-to-org function, I will use that one in debugging.

I agree - but unfortunately at the moment I won't be able to help here.
