Hmm, according to the docs, shouldn't the following work?
[ 74 ikipostal/test ] ikiwiki --dumpsetup out.setup foo bar [ 75 ikipostal/test ] perl -MIkiWiki::Setup -e'IkiWiki::Setup::load("out.setup");' out.setup: Can't use an undefined value as an ARRAY reference at /usr/share/perl5/IkiWiki/Setup.pm line 37. BEGIN failed--compilation aborted at (eval 15) line 233.
From looking at the code, it seems that a global hash %config should be initialized somehow.
This is in ikiwiki 2.62.1. I think this call used to work in 2.54 (when you first refactored the setup IIRC)
Updated: It seems that
%config = IkiWiki::defaultsetup();IkiWiki::Setup::load("file");
works (afteruse IkiWiki; use IkiWiki::Setup;
). Of course the other api is nicer.
