Re: [O] Painfully Slow Export

[Ken Mankoff]

Hi Chuck,

It looks fine to me. I see:

Name: fig:foo

Lang: python

Properties:

:header-args :eval never-export

:header-args:python nil

Header Arguments:

:cache no

:eval never-export

:exports results

:hlines no

:noweb yes

:results file replace

:session discharge_ts

:tangle no

  

  -k.

That is the right idiom.  Of course, you have to refresh the local setup after typing that (C-c C-c with point in the PROPERTY line) or it will have no effect until you save and re-open the file.

It is good to check that you have refreshed and that there are no typos or hidden chars in the line, so go to a src block and type

C-c C-v C-i

and verify that you see something like this

You should see both the :header-args line as you typed it and the :eval line showing never-export.

Leave it set to `t'.
