Hi Stuart,
Thanks for your quick response. You were right at pointing out that the
problem occured in documents which used asciidoc styles in some table
columns, like the ones I was trying to compile. I found out that you can
set the sys.executable property just by
setting -Dpython.executable=/usr/bin/python JVM property. I did and it
worked, although the workaround has now native python dependency, which I
tried to avoid but it is ok for the time being.
I'm a complete newbie with python but a quick look at the source code
(asciiidoc.py) showed me that some process forking is being done for filter
application, even in case the filter is asciidoc itself (which is the case
for asciidoc styled columns):
p = subprocess.Popen(filter_cmd, shell=True,
stdin=subprocess.PIPE, stdout=subprocess.PIPE)
Wouldn't it be possible to avoid the call to subprocess.Popen(...) in this
case and use just a recursive call to asciidoc.py instead? or isn't it
reentrant and cannot be called this way?
Thanks a lot,
Daniel
