Some advice on how to use babel to generate cisco configs

Some advice on how to use babel to generate cisco configs

[Bart Bunting]

Good morning,

I have been trying to figure out without much luck how to use babel to
generate some cisco configs.


What I would like to achieve is to have a table containing a few values,
e.g. ip address vlan number etc.

Then have a cisco config in the org file with markers where the
substitutions are to be inserted.
Run through the table and create a node in the org file one for each row
of the table.

The end result should be a set of cisco configs with the substitutions
made.  I was hoping to also use shell to call pwgen to generate a
random password to insert.
  
Hope that ramble made some sort of sence.

Can someone give me some ideas on how to put this together?

I tried to use an org source block and a shell function to parse it.  I
couldn't quite tie together how to get the output to work correctly or
how to be able to parse each line....


Kind regards

Bart

Are you planning to use this as a one-time creation thing or do you
want to re-run (and re-generate) the configs from the same table
multiple times?

If it is one-time only, you might be happy using a yasnippet
template which generates your substitutions.

I don't know a Cisco config from a fig newton, but here is my sense of
what you wrote, in case it is helpful.

#+name: cisco-table
| 1 | one   | two  |
| 2 | three | four |
| 3 | five  | six  |

#+header: :results output raw
#+header: :var x=cisco-table
#+begin_src python
  for y in x:
      s = "* Cisco %s \nTwiddle %s, poke %s \n\n" % tuple(y)
      print s,
#+end_src

#+results:
* Cisco 1 
Twiddle one, poke two 

* Cisco 2 
Twiddle three, poke four 

* Cisco 3 
Twiddle five, poke six

Thomas,

Thanks!  That is pretty much what I was struggling with.

Thanks for putting it together for me.  

The only other question I have is, is there a way to prevent the results
from appending each time?


Cheers

Bart

Good news.  I'm happy it's starting to work for you.

See the manual, 14.8.2.2 :results.  You probably want :results replace.

All the best,
Tom
