Limit on length of babel block #+name: value?

Limit on length of babel block #+name: value?

[John Hendy]

I was just completely baffled for about 5-10 straight minutes as to
why my block was not producing a  results section with my generated
graphics file from an R block.

I kept double checking my header options one by one despite having
simply copied/pasted/modified it from a previous working block. Turns
out it appears that #+name has a character limit!

This (on Org-mode version 8.0.2 (release_8.0.2-65-g1e32d7)), doesn't work:

#+name: improvement-treatment

It appears the name can be 20 characters long (the above is 21).

Is this by design or something I accidentally uncovered? Forgive me if
it's come up before or is documented. I did a couple searches but
didn't see it.


Thanks,
John

Hi,

I cannot reproduce this on 8.0.2, at least not with the info
provided. E.g., the following works fine:

#+name: improvement-treatment
#+begin_src R :results graphics :file test.png
  x <- 1:10
  y <- x^2
  plot(x, y)  
#+end_src

#+RESULTS: improvement-treatment
[[file:test.png]]

So does any variation with an arbitrarily long string as NAME.

Yours,
Christian

I don't think there is any name length limit.  The attached example
works for me, and exports w/o problem to HTML.  Maybe I'm not using the
block in the same way as you, but I'm pretty confident there is no name
limit and your problem probably lies elsewhere.

There is no name length limit

#+name: improvement-treatment
#+begin_src sh
  date
#+end_src

#+RESULTS: improvement-treatment
: Thu May 16 06:04:20 MDT 2013

Calling this block.
#+call: improvement-treatment()

#+RESULTS: improvement-treatment()
: Thu May 16 06:04:36 MDT 2013

and even longer

#+name: improvement-treatmenttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt
#+begin_src sh
  date
#+end_src

#+RESULTS: improvement-treatmenttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt
: Thu May 16 06:05:04 MDT 2013

Calling this longer block.
#+call: improvement-treatmenttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt()

#+RESULTS: improvement-treatmenttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttttt()
: Thu May 16 06:05:24 MDT 2013

I can't replicate anymore, though I did just update Org. Perhaps I
should have fiddled with it more before doing that...

If it happens again, I'll dig into it. Thanks for double
checking/attempting to replicate -- must be on my end.
