code blocks: update cache hash on export

code blocks: update cache hash on export

[Ulrich J. Herter]

Hi everybody!

Two questions I'd like to ask the Org-community: 

First:
When I export my document, the source blocks with outdated cache hashes
     run, but no new hashes are put in the document.

I would like to have the hashes updated when the run on export, so next
time I export the don't need to be evaluated. This would save a lot
quite some time!

Is there a switch I missed, or any way to get this behaviour?


Second:
Is there a function to get the hash of a #+CALL:-block? C-c C-v a ()
doesn't work there.


Thanks a lot,
Ulrich

Right. The exporter runs in a buffer copy, so the original is not modified.

Run org-babel-execute-buffer (or org-babel-execute-subtree) before you 
export.

`org-babel-current-result-hash' does this. It is not interactive, so if 
you want to query the value interactively, you need

  M-: (org-babel-current-result-hash)

with point in the CALL line. Or roll it into an interactive function of 
your own.

`org-ctrl-c-ctrl-c' will get the value if point is just before the hash.

HTH,

Thanks Chuck, that helps.

One more thing:

M-: (org-babel-current-result-hash) returns the hash from the previous
run. What I would need is the new hash which would be inserted after a
new run.

On source block I can get the new hash with M-x org-babel-sha1-hash or
C-c C-c a, but this isn't working on CALL lines. Is there a function
that could do that?

Thanks
