Dear asciidoc users,
In my asciidoc documents I will replace each occurence of
"pagenumber::original[2]" with the output of the attached python script.
The python script standalone works as expected. But how could I tell
asciidoc to call the python script if the value above will be found?
The attached config seems to be wrong. Because it is hard to understand,
could ypu point me to a very good documentation how to configure such a
filter? Otherwise could you please give me an explanation of an example?
If my asciidoc file has following text:
----------- snip ---------
pagenumber::original[2]
An ſeinen Ufern läuft das Schienenband,
Sich ſchwingend über kühn gewölbte Brücken;
----------- snap ---------
the docbook via "asciidoc -b docbook -f ./orig_pagenumber.conf" should be:
----------- snip ---------
<emphasis role="orig_pageno">2</emphasis>
An ſeinen Ufern läuft das Schienenband,
Sich ſchwingend über kühn gewölbte Brücken;
----------- snap ---------
Thanks in advance,
with best regards
Andreas
