Re: Tweaking the export

[Christian Wittern <cwittern@gmail.com>]

Hi Nicolas,

Thank you very much for taking the time for such a detailed recipe.  Today I 
finally found time to go over it and try to implement my transformer.  It 
turned out to be really easy to get going, but in the end, I hit a roadblock.

It worked wonderful until here.

With a little tweaking, I got rid of errors when running this code.  
However, no changes in the output where observable.  Finally, I looked at 
the output from step 3 above and realized that the parser normalizes my 
<tab> characters away.  Only a bunch of spaces in the output!  Ouch!!
So I guess I would need an option on the parser to switch tab expansion off.

I also intended to implement my transformer in a way that I first define the 
general org-e-org transformer and then derive a specialized transcormer by 
somehow inheriting the general transformer and then implement my specialized 
paragraph transformation.   It seems that this is at the moment not 
possible, but I think it would be good to think about this, that will make 
defining new exporters or even org-file tweakers a breeze.

Anyhow, again thanks for writing the new parser /  exporter and for your 
help with my problem!

All the best,

Christian
