Dear all,
I'm in front of a strange problem: I have a .lua script that can be
called from both luatex and texlua, and I would like to have a different
behaviour according to the caller. The problem is that I cannot find a
reliable way to know if the script is called with texlua or luatex...
I cannot inspect arg[0] because some scripts are just symbolic links to
texlua or luatex and it's impossible to have information from it.
I cannot try texconfig.formatname nor texconfig.jobname as these are
never filled in the formats in TeXLive (this is something I would like
to address soon).
I tried to look into ConTeXt sources, but I did not manage to find a
clue (especially since I don't know the sources well)...
What would be the best solution?
Thank you,
